What Momma Never Told Me about SEO

I just attended the Inbound Marketing University Webinar “Advanced SEO Tactics: On Beyond Keyword Research” led by Rand Fishkin of SEOmoz, and I must admit I’m feeling a little frazzled. Why? So many of my cherished SEO beliefs have been turned upside down.

Search Engine Ranking: It’s Not All About the Content

The content on a Web site is not nearly as important to SEO as the context that site inhabits on the Web: Which other domains link to it? How many other domains link to it? What is the quality of those links?

According to a survey of 70 SEO experts, your site’s search ranking depends much more on external factors such as inbound links than on onsite content.

Expert opinion: Relative Importance of Algorithm Components in Google

See that purple slice? The content on your page is about 15% of what Google considers when ranking your page. Anchor link text (the green slice) also affects SEO, but inbound links and host domain authority (does Google have reasons to “trust” that your Web site is legitimate?) are by far more influential.

Inbound Links Trump Onsite Keyword Usage

The very large, very bright orange wedge in the following image represents the overwhelming influence of link popularity—the number of other domains that link to your site—on your search rank.

What About Keywords?

Aw, shoot. You just spent 6 months researching the best keywords for your site. Now you need to go do some link building. But since you’ve got those keywords anyway, where will they do the most good?

Keywords in your Domain Name Really Matter.

Keywords in H1, H2, H3 tags? Not so much.

So you’d think that if site content is not the most influencing factor in your search rank, it should be second, right? Nope. That honor goes to your domain URL. Keywords in your domain name (www.yourdomainname.com) exert nearly twice as much influence on your search rank as keywords in site content.

Correlations between Web page data and search ranking

When it comes to site content, your title is one of the most important elements on the page, so be sure to use keywords as close to the beginning of the page title as possible. (Good: Used Cars for Sale | Thomson Motors; Not As Good: Thomson Motors | Used Cars for Sale).

Heading elements exerted little to no influence on search rank, according to Fishkin’s data. That doesn’t mean that you should stop paying attention to headings. Fishkin recommends sticking with best practices. You are creating pages for people, not search engines, and people appreciate a clear, descriptive header.

Alt Text Rules

I was very surprised to hear that high search rank is closely correlated to the use of alt text on images. The alt attribute contains a brief description of an image. When you view a screen with images disabled, you’ll see the alt text in place of the image. Search engines are blind and deaf, so the only way they can recognize an image is by its alt text.

One webinar participant asked if this correlation was due to the fact that anyone who includes quality alt attributes is already on the ball when it comes to SEO, and Fishkin conceded that this might indeed be the case.

In any event, it is always a good idea to include alt text for images. Purely decorative images (such as spacer gifs) should contain a null (empty) alt attribute.

Key Takeaway 1: Focus on Link Building, but Don’t Abandon Best Practices

I know that I, for one, will be redoubling my efforts at link building for SEO. It’s important, however, to continue dotting those i’s and crossing those t’s in our Web development practices. Code correct HTML markup, write good heading text, and concentrate on delivering high-quality content to your audience.

Key Takeaway 2: Links Trump Content, but Content Earns Links

(or, Great Content Is Useless Unless It Compels People to Link to It)

This clever tweet came from Rena Bernstein during the IMU Webinar

As rattled as I was to hear that my precious H1 elements were not sacrosanct, I took comfort in the knowledge that unique, substantive content is still the name of the game. Without useful content, there’s no reason for people to use the Web at all. The key is to keep focus on both content and context. We want to create great content that results in other people discussing it and sharing it. The links generated from that online discourse improves our search rank.

Key Takeaway 3: No Site Is an Island

A large part of how easy you are to find on the Web is reliant upon your relationship to others. Are they interested in you? Do they talk about you? Do they link to you? When someone runs a Google search using a keyword, Google looks for the best, most relevant results to deliver. One way it decides if your Web page is a good-quality search result is how popular it already is. If others found your page useful, then the searcher might as well.
