Book Excerpt: What Are Authority Links?

The following is an excerpt (with some recent modifications and editorial comments) from our book, WordPress Search Engine Optimization (now in second edition!). You can buy the book at Amazon.

Authority Links: What They Are and Why You Want Them

There is a measure of power that some links possess that is independent of PageRank and it is the principle of authority links. Authority links are links from websites that have established a substantial degree of trust and authority with search engines as a result of their age, quality, and size. Authority is a somewhat subjective concept. Unlike PageRank, neither Google nor the other search engines offer any public reference or guidelines as to what constitutes an authority site or authority link. Authority sites are going to be the market leading sites, sites representing established government and educational institutions, large corporations, or leading websites. Authority links can bring tremendous ranking power to a website if one is lucky enough to obtain one or more.

Authority links are the golden eggs of link building. They tend to be extremely difficult links to get, and for that reason most webmasters rarely get them. The best approach to authority links is to be vigilant for opportunities to obtain them, but it is most likely fruitless to waste time seeking them out.

Our discussion of PageRank and authority links leads naturally to the notion of the relative power of inbound links. No two links are the same in terms of power. The degree of authority of a site, the PageRank of the page upon which the link appears, and the number of outbound links on the page where your link appears will all effect the relative value of the links you obtain. That said, almost all links are worthwhile, even lower value links. With what we’ve learned in the previous few pages, you will have a strong sense of how to evaluate link opportunities and to evaluate the relative strength of links.

Sometimes, you’ll be forced to settle for lower value links but in higher volumes, as is the case with link directories. But never fall into the trap of thinking that the only links worth getting are high-authority, high-PageRank links. All links are good for your rankings (except links from link farms and content farms, from which you should never seek out links).

Link Anchor Text

A vital concept in link building is link anchor text. Link anchor text is the word or words that constitute the visible text of the link itself, the “blue underlined text” as it is often called. The anchor text of a link is a powerful ranking factor; anchor text serves as a signpost to Google as to the content and subject of the destination page.

How Anchor Text Appears in HTML Code

The anchor text of a link is coded by placing the desired text between the open and closing markup of the hyperlink:

<a href="https://tastyplacement.com/">This Is Anchor Text</a>

Controlling the link anchor text of inbound links is vital whenever possible. The problem is that you can’t always control the anchor text of inbound links. And unfortunately, the higher quality the link, the more restricted you’ll be in choosing anchor text. A perfect example is the Yahoo Directory. A link in the Yahoo Directory is a great link to get, but Yahoo dictates that the anchor text you select be the name of your website or the name of your business. Yahoo does not allow you to stuff keywords into the anchor text. Here lies another good reason to choose a keyword-rich domain name for your website and business. When your business name is carefully crafted to comprise keywords, like “Austin Air Conditioning,” then you can employ those high-volume keywords more easily in your link building efforts.

To continue an example from an earlier chapter, if you have identified the phrases “Jacksonville air conditioning,” “Jacksonville air conditioning contractors,” “Jacksonville air conditioning companies,” and “Jacksonville air conditioning repair,” as the keywords around which a specific page is built, then your anchor text selection is nearly complete. You can use the same keywords as your desired anchor text.

When you can control the anchor text, you should craft the anchor text of links based on the keywords you have designated for each destination page. With this device used in connection with sound on-page optimization, tremendous ranking power comes into focus. Remember that Google and the other search engines have a primary goal of returning quality search results to their visitors. When anchor text accords with the on-page elements of a web page, that gives search engines confidence as to the subject of that page. And, when a search engine is confident about subject matter, it rewards the page with high rankings.

But be careful with anchor text when gaining links in high numbers. It is unwise to secure hundreds of links all with picture-perfect anchor text; this manner of link building does not appear natural to search engines. There is a risk of over-optimization when your link anchor text is too perfect. Generally, you never want more than 70% of your anchor text for a particular page to be solely based upon a small family of perfect keywords. Thus, there is a hidden benefit to garnering links for which you can’t control the anchor text because these links dilute your principal keywords to some extent.

If your anchor text isn’t varied naturally, then you should intentionally vary the anchor text. Clever SEO professionals sometimes go as far as to obtain noise links. A noise link is a link with common generic terms used as the anchor text like “click here,” or “website.”

Not all hyperlinks have anchor text. Images can be hyperlinks, but do not use anchor text. In this case, search engines register the link but have no anchor text upon which to determine the subject matter of the link. Links in image maps and flash files suffer from the same limitation. For this reason, such links are less desirable.

Should You Disallow Old Link Structures With Robots.TXT?

Questions from Readers…

We’re getting great questions from readers of our book, WordPress 3.0 Search Engine Optimization. Today, Michael tackles a question sent in by Jeff of Houston, TX. Remember, send in those questions and feedback! We’re always  thrilled to help out our readers.

Hi Mr. David,

I’m sorry to contact you with such an insignificant matter, but I just got your book today and wanted to ask if you could clarify an issue that I have encountered. My site has been up for about 6 months and I had been using a permalink structure of /year/month/day/postname and I changed it to /category/postname. I also used Deans Permalink Migration plugin to add 301 redirects for published posts.

I want to use your Ultimate Robot.txt file to my site, but I’m wondering if I add the “Disallow: /2011/ ” directive to eliminate duplicate content in my archives, will it disallow my previous posts that had /2011/ in the old permalink structure? Any help or clarification on this issue would be very appreciated. Thank you for your time.

Jeff

Houston, TX

Jeff,

We love hearing from readers.

Yes, I believe that if you add the directive Disallow: /2011/ you will remove year archives from indexing, but also any post that uses the year in that position as part of its permalink structure. I tested it, and it appears to disallow the content.

You can test your robots.txt file by using Google Webmasters’ Crawler Access testing tool. The tool lets you test the text of a robots.txt file and compare it to a specific URL. The tool then tells you if your robots.txt file is allowing or blocking the URL. You can find the tool by logging into Google.com/webmasters and then selecting “Site Configuration” and then “Crawler Access” from the left menu. We didn’t cover this specific tip in WordPress 3.0 Search Engine Optimization, but we will implement it in a future edition of the book.

Now, but you say you’ve changed your permalink structure–that should solve the problem. In the case where a robots.txt entry would block regular blog posts from getting indexed when blocking year archives, the solution is clear: don’t block either. Just make sure your year archive is set to display excerpts of the posts, rather than the full text of the posts.

Are Site-wide H1 Tags in WordPress Good or Bad?

Questions from Readers

The great thing about writing our book, WordPress 3.0 Search Engine Optimization, is we get to hear from all those readers who have taken our material and put it to work in the field. Today, we’ve got a fascinating question from Robert, who asks that question we confront every day in one way or another: Just how far should I trust Google’s sophistication?

Hi Michael,

I’m currently reading your Packt book on WordPress SEO, and I have a quick question about HTML5 and the way it uses header tags. Your book says to use only one H1 tag per page, which makes sense. However, HTML5 advocates multiple H1 tags per page, as long as each is contained in a separate section/header.

Worse yet, the first H1 tag on a page is usually a wrapper around the home link logo and contains the same meaningless title text on every page. You can see a typical example at CSS3maker.com :

<header>

<h1 id=”logo”><a href=”index.html” title=”CSS 3.0 Maker”>Css 3.0 Maker</a></h1>

</header>

Most SEO bloggers assume single H1 tags are a thing of the past. Based on your experience, has there been any evidence that Google/Yahoo interpret HTML5 content any differently than HTML/XHTML?

If not, should I remove the header and h1 tags around my logo anchor tag? My site looks like the CSS3maker code above. And like them, I don’t have anything else in my header, so if I remove the H1 tag, wouldn’t I also just scrap the header tag? I have a meaningful H2 tag in my content section, which could be elevated to an H1 tag.

Thanks,
Robert

BTW, I’m really enjoying your book.

 

Robert,

This may be a cop out…but does this help?

I think google is tuned in enough to ignore site-wide h1 tags. One of my philosophies is “packaging”–make it so brain-dead easy for a search engine that it can’t POSSIBLY get confused. We are sort of on-page nerds when it comes to that stuff. Most of the pages we create are pretty perfect, at least on the page.

Do we, in our SEO business, remove site-wide h1 tags around logos and site names in the header? Absolutely we do, but I don’t think it’s the kiss of death if you don’t. Remember one thing: google has to fit its algorithm so that it doesn’t punish sites for small mistakes–otherwise, it would punish 80% of the web or more.

I am very glad you are enjoying the book!

SEO Master Class: The Mathematics and Operation of Google PageRank

The following is an excerpt (with some recent modifications and editorial comments) from our book, WordPress Search Engine Optimization. You can buy the book at Amazon.

The Mathematics and Operation of Google PageRank

Google’s PageRank is part of its search algorithm; the other search engines’ ranking algorithms work similarly. Yahoo and Bing, while they obviously measure inbound link counts as a ranking factor, do not disclose to web users any measure of page value equivalent to PageRank. PageRank works through complex mathematics. Understanding the mathematical intricacies is not vital, but can help illuminate how PageRank impacts your link building efforts. PageRank works the same on all platforms, WordPress or otherwise.

The PageRank Calculation

PageRank calculations works as follows: Google assigns a numerical value to each indexed page on the Web. When an indexed page hyperlinks to another page on the Web a portion of that numerical value is passed from the linking page to the destination page, thereby increasing the destination page’s PageRank. Inbound links increase the PageRank of your web pages and outbound links decrease PageRank. PageRank, often abbreviated as “PR,” is expressed as a number from 0 to 10. Google.com and Facebook.com, both of which benefit from millions of inbound links, enjoy a PageRank of 10. In common parlance, a PageRank 10 site is referred to as a “PR10 site.” Remember though that PageRank refers to pages on the web, not just sites themselves. A PR5 site simply means that the site’s front page is a PR5.

So how is PageRank specifically calculated? Every indexed page on the web enjoys a small amount of PageRank on its own, a PageRank score of 1. This inherent PageRank is the original source of all PageRank on the web; it is only through linking between pages and sites that some pages accumulate higher PageRank than others. However, a page can never send all of its PageRank to other pages—this is where the damping factor comes into play. The damping factor is simply a number between 0 and 1 (but think of it as zero to 100 on a percentage scale); it represents the amount of PageRank that can be sent away from a page when that page links out to other pages.

If a search algorithm’s damping factor were set to zero, no page would ever send PageRank away, and the entire PageRank calculation becomes pointless. On the other hand, if the damping factor is set to 1, then 100% of a page’s PageRank is sent away through outbound linking, and any page with any outbound links retains no PageRank. In this case, the algorithm also fails—the internet would be populated entirely sites of either PR0 or PR10 with no sites in between. As it happens, the damping factor employed by Google is widely believed to be .85. This means that 85% of a page’s PageRank is available to be passed to other pages through linking, while 15% of a page’s PageRank will always be retained. It is believed that Google can alter the damping factor for particular sites.

Consider for a moment that Google manages PageRank calculations for billions of web pages. If that wasn’t daunting enough, consider that Google undertakes the even more staggering task of managing the mathematical calculations of immeasurable numbers of links between those billions of sites.

PageRank, Diagramatically

This graphical illustration of Pagerank calculations for a hypothetical group of web pages shows that the PageRank distribution is accumulated in site “B” because it enjoys a high number of links. The sites represented by the small circles at the bottom of the illustration retain only 1.6% of the PageRank distribution because they link outward and have no inbound links. Note also that site “C” enjoys a healthy amount of PageRank simply because it enjoys a single link from site “B.”

You Have to Share Your PageRank

Also bear in mind that the amount of PageRank available to be passed by a page will be equally divided among all the outbound links on that page. So, if a webpage has a total of six links: three internal links and three external links (links to outside websites) then the PageRank passed away by that page will be shared equally among the six links on that page.

What does that mean for the link builder? Well, it means that if you have secured a link on a great PR4 page, but that page has 200 outbound links, then you’ll be sharing the available PageRank with 199 other sites. That’s why you want to seek out pages with low numbers of outbound links. When there are fewer outbound links, your link will enjoy a much greater percentage of the available PageRank.

The Logarithmic PageRank Scale

If the mathematics underlying PageRank weren’t complicated enough, there is another facet that you must consider. The PageRank scale of PR1 to PR10 isn’t linear, it is logarithmic. Therefore, it takes ten times as much linking power to rise from a PR2 to a PR3 page. Expressed another way, a PR4 page has 100 times the linking power of a PR2 page. As each level of PageRank is reached, it becomes harder and harder to reach the next level. There are only about 120 to 150 PR10 pages at any given time, and generally this elite class of pages and sites includes Google.com, Microsoft.com, WhiteHouse.gov, and other sites of equivalent popularity and character.

PageRank Is Historical

PageRank is historical and only updated every three months or so (although sometimes much longer periods pass between PageRank updates, it’s really up to the whim of Google)—when you check the PageRank of a page, you aren’t seeing the current PageRank, you are seeing the PageRank reported as of the last PageRank update.

SEO Master Class: Choosing a Keyword-Rich Domain Name

The following is an excerpt (with some recent modifications and editorial comments) from our book, WordPress Search Engine Optimization. You can buy the book at Amazon.

SEO Master Class: Choosing a Keyword-Rich Domain Name

Almost all websites will rely on primary keywords on core pages like the front page. If your keyword research teaches you that one phrase or a very small group of related phrases represents your high-volume, high-relevance primary keywords, then you’ll want to consider using those keyphrases in a keyword-rich domain name. For some, this won’t be possible or desirable: perhaps the domain name has already been chosen, or the business’ marketing strategy revolves principally around a customized brand name. But if you have the opportunity to choose a keyword-rich domain name, you’ll benefit from a little extra power in your ranking efforts down the road. You may have noticed that often a competitive search market is populated with websites that have keywords in their domain name. This is no accident: key terms in the domain name is a ranking factor and experienced webmasters know it.

Whatever you do, choose wisely; if you ever need to change your domain name, it’ll take a lot of work and you’ll loose both incoming links and existing customers.

Tip:

SEO professionals know that you don’t always have—and won’t always need—every SEO element (domain age, keyword-rich domain name, expert title tags, thousands of inbound links, etc.) to rank well. When you consider all the elements together that make a site rank well, you want to make sure you have 80% of the elements present—but don’t fret if a few elements are out of your control.

Domain names are certainly an element that search engines consider as a ranking factor. Remember a search engine’s core purpose: to deliver relevant search results to a user entering a query. Certainly a domain name that includes a few of the searcher’s query terms would tend to be relevant for that query. The weight afforded by search engines to keywords in the domain names is moderate. In competitive markets, a keyword-rich domain name can provide some extra push to pass tough competitors. This can be frustrating in a market where every conceivable variant of a domain name has been snatched up.

Also keep in mind that keyword prominence applies to keywords in domain names. This means that the first words in a domain name are afforded greater weight by the search engines than the last words in a domain name. You will also want to mirror the word order of popular search phrases whenever possible and keep your important terms first in the domain name.

To craft a domain name, begin with your primary keywords. We’ll use some real keyword data and search volume surrounding the keyphrase “Denver homes” as an example.

Keyword Monthly Search Volume
Denver homes for sale 1000
Denver homes 1000
Denver homes for rent 280
new homes Denver 280

The preceding table demonstrates a few important points:

  • “Denver” is the first word in both of the highest volume key phrases.
  • “Denver” appears in all four of the keyword variations.
  • “Homes” appears in all four of the keyword variations.

In this example, the terms “new” and “for rent” aren’t the valuable terms—unless of course your website is concerned with rental homes and apartments in Denver, in which case the “Denver homes for rent” keyphrase is the only relevant one on which to base your domain name. With “Denver” in the first position for the majority of searches, you will want to maintain that word order.

You should also consider keyword overlap in crafting domain names. Keyword overlap exists when one key phrase or keyword is incorporated either partially or fully within another—and you can use it to your benefit. In our example, “Denver homes” has full overlap with “Denver homes for sale.” When you see overlap like that with robust search volume for both phrases, the longer key phrase becomes even more attractive as a primary keyword for your domain name. “New homes Denver” has only a partial overlap, and even that’s a stretch because the word order is reversed.

And so, in our example, the path is clear: “Denver homes for sale” is a highly desirable high-volume phrase to use as the basis for a domain name. But what to do if “denverhomesforsale.com” is already taken? You have two options: buy an existing or dropped domain, play with hyphens, or create a clever variation with extra words.

Buying/Acquiring Domain Names

You can always buy a domain name from its owner or wait for an existing domain to expire (so-called “dropped” domains). For dropped domains, there are a host of online services that, for a fee, will help you navigate the increasingly complex world of expired domains. This approach will yield some some inevitable frustrations: the system is dominated by experts that have mastered its subtleties. As a newcomer, you’ll likely have to endure a learning curve. Also, an owner of an expired domain is entitled to a redemption period during which you’ll have to wait if you want to snatch up a choice domain. For most SEO pros, the extra time and risk isn’t worth it—especially when you can overcome a less-than-perfect domain name with sound on-page optimization and some extra linking power.

You can also buy a domain in the aftermarket from an existing domain owner. Dangers to watch our for with this approach are that some domain owners make it impossible to be found, and when you do find them, they have a completely deluded sense of the domain’s value. Services like sedo.com and domainbrokers.com maintain ostensibly active listings of domains for sale. Domain registrars like godaddy.com offer domain “buying services” where you select a desired domain name and they attempt to secure it for you.

In the domain resale market, asking prices for domains are typically astronomical. Overall, the domain resale market is riddled with complexities, dead ends, and punitive pricing. If you do undertake to purchase a domain, either by resale or following expiration, be prepared for a hunt. Smart SEO professionals don’t overpay for domains, and they certainly don’t endure unreasonable delays to launch their next project.

Hyphens and Extra Characters in Domain Names

It’s true: all the easy domain names are taken. But you still have an opportunity to fashion a keyword-rich domain name with a little creativity. All domain names must follow these technical rules:

  • Domains can include letters (x, y, z).
  • Domains can include numbers (1, 2, 3).
  • Domains can include dashes/hyphens, and can be repeated in sequence (-, –, —).
  • Domains cannot include spaces.
  • Capital letters are ignored.
  • Domains can’t begin or end with a dash.

Hyphens present a good opportunity. In our example, we might consider checking for the availability of denver-homes-for-sale.com. This domain keeps the keywords in order, maintains keyword prominence, and the hyphens have two benefits: they certainly make the domain easier for humans to read and can help search engines distinguish the words (i.e., “kitchens pot,” vs. “kitchen spot”). The drawback of hyphens—and it is worth consideration—is that hyphenated domains are awkward and unmemorable and can appear trashy. Visitors are unlikely to remember your specific combination of words and hyphens. It can also be inconvenient to express your email address repeatedly as “Peter at Denver homes for sale , dot com, with hyphens between all four words.” That said, in a pure search environment, where you are going solely for keyword-based traffic, you can worry less about memorability. You’ll be getting your visitors solely from search and not requiring repeat visitors.

Hyphenated domains have a fairly-deserved reputation as being a bit trashy; many link farms and thin content sites employ hyphens in their domain names.

A helpful variant of this technique is to simply apply a suffix to the domain, such as denverhomesforsalenow.com or denverhomesforsale303.com (303 is an area code in Denver). Get creative: think of a term that adds to your domain. The terms “express” and “pros” have positive connotations. “Express” suggests speedy, high-value service. “Pros” suggests someone licensed with experience. Find an appropriate suffix for your domain and you will have a keyword-rich domain without the hassle and expense of purchasing in the domain aftermarket.

As a final word on domains, make sure you use a reputable domain registrar. Some disreputable registrars may make it difficult for you to transfer you domain away later.

Tip:

Don’t park your domains, put up content! Domain registrars like GoDaddy offer domain parking “service.” This isn’t a service at all—it’s a way for GoDaddy to squeeze a few pennies in pay-per-click ads out of your domain. The better approach is to put up even just a few paragraphs on your domain just to get the search engines indexing the page and building up some site age. Parked domains don’t earn site age.

Book Excerpt: How to Use Demographic Data to Find Wealth Centers

The following is an excerpt (with some recent modifications and editorial comments) from our book, WordPress Search Engine Optimization. You can buy the book at Amazon.

Follow the People, Follow the Money

When building your keyword list, you’ll always want to return to the question “who is my customer?” If you are a deck builder, pool builder, or plastic surgeon, your customer is a homeowner (in the case of home services) and a person of financial means (in the case of home services or plastic surgery). It’s obviously helpful to know where the people with the money live. If the residents of a town or neighborhood aren’t able to afford your product, you’ll obviously not want to market there. Similarly, you’ll prefer to put your efforts into high-population areas over low-population areas. This same approach can apply to other demographics that might impact your bottom line: where are the families with children? Where do the senior citizens live? These inquiries are basic demographic questions that you can use to focus your keyword strategy.

For most, you’ll have a sense of your own community: where the population centers are, where the wealthier people with disposable income live. There may be other variations: areas with new home construction underway are a gold mine for home services like window blinds, alarm companies, and pool builders.

If you don’t have a true encyclopedic understanding of the demographics of your region, or you simply want to deepen your understanding of the local marketplace, there is a great web-based tool that can help you “follow the money.” The tool is Webfoot Maps and can be found at http://maps.webfoot.com/. Webfoot has created a collection of demographic-based Google Maps mashups that visually represent demographic data like population density and household income as an overlay over a standard Google Map. With this tool, you can zoom into your town and see where the population centers are and where the high-income folks are living.

The site offers a tremendous amount of data and it can be very helpful in crafting a keyword strategy. The census data upon which the site relies is from 2000, but will likely be updated soon when the new 2010 census data becomes available. To use the tool, browse to http://maps.webfoot.com/ and follow the link for “US 2000 Census.” From there, you can select any of the following demographic criteria:

  • Median Household Income
  • Population density
  • Median Owner-occupied home value
  • Median age
  • Median home value/median income
  • Percent White
  • Percent Black
  • Percent Hispanic
  • Percent Asian
  • Percent Native
  • Percent Female
  • Percent Male
  • Percent of owner-occupied housing units
  • Percent of renter-occupied housing units
  • Percent of vacant housing units
  • Average household size
  • Average family size
  • Percent with college degree
  • 2008 Unemployment Rate (county)
  • 2007 Unemployment Rate (county)
  • Unemployment Rate Change 2008-7

Webfoot presents sensible graphical data for each default selection, but you can adjust the “Value” parameter to display, for example, only areas with incomes above $100,000 per year.

Webfoot’s demographic Google Maps mashup at work displaying household income in the geo-markets including and surrounding Kansas City. Darker areas indicate higher income levels. Areas with higher incomes can present excellent web marketing opportunities for some businesses.
