It’s been said that Google takes over 100 different considerations into account when figuring out where to return your page in a search result. Even though that sounds like a lot, all those 100+ factors can be boiled down into two core concepts. To rank well, you need to maximize both.

Ranking = Strength + Relevance

Page Strength

I know a lot of SEO’s love to say PageRank is dead. I disagree, and see evidence of it every day. Sure, PageRank is certainly not as important as it used to be, but it’s certainly not dead.

PageRank is a measure of how important a page is on the Internet as a whole. Every page that links to your is essentially counted as a vote of confidence for the page. Links from important pages like the New York Times count more than links from lesser pages like your brother’s personal blog about his dog. To over-simplify things greatly, Google’s PageRank score is a sum of the value of all those votes in comparison to all the other pages on the web.

There are other factors adding to a page’s strength as well. Such as:

• Is the page new?
• Has the page and/or domain been around for many years?
• Is the domain registered for a long term between renewals, like 5 years?
• Is the domain or page penalized for not following the webmaster guidelines?
• Is the domain selling links?
• Is the page located in Wikipedia? (OK - maybe not that one)

I know I’m missing some factors, but you get the general idea about what might play into strength.

What’s clear though, is that your page is never going to rank well on strength alone.

Ranking well needs one additional key factor…relevance.

Query Relevance

If strength was all that was required, a site like www.google.com would rank #1 for all queries…it’s a PageRank ten out of ten. That obviously would not make sense.

Relevance is a measure of how related a page is to what the user has search for. Your brother Joe’s blog about his dog, even though not a strong site, may very well be the most relevant destination for people searching for “joe dog blog”.

Relevance factors include:

On-Page:

• Query Terms in the title?
• Query Terms in header tags?
• Query Terms in body text?
• Query Terms in outgoing link text?

Off-Page:

• Query Terms in incoming link text?
• Query Terms in “on page factors” of the pages linking in?

It’s possible for a page to rank well based on a strong relevance while having a low pagerank, which is why some people say pagerank is dead. (That doesn’t mean PageRank is dead, it just means there are other factors than can overcome a low pagerank.)

Burn the Candle on Both Ends

Strength and Relevancy are simple high level concepts that can be easily explained and understood by both technical and non-technical users alike.

Some tasks, like link building, will have an impact on both.

For a strong ranking, your strategy should be to maximize both strength and relevancy. Don’t give one the blind eye.

Matt Cutts opened up a whole new world of possibilities when he told Rand from SEOmoz that it’s acceptable for a site owner to use nofollow on internal links to control the flow of PageRank within a site.

There’s a whole can of worms that has been opened up by internal use of nofollow being considered white hat. Matt muddied the waters a bit in this comment, but still indicates internal use of nofollow is a white hat tool webmasters can use by saying “It’s available if you want to get into that much fine-grained control.”

So far the best information I’ve seen about this is the Third Level Push (modified Siloing) For Deeper Index Penetration. That’s an excellent post, tool, and process, but it’s not the whole story. It’s also a little hard to get your head around.

On most sites, especially smaller ones, I don’t think PageRank sculpting is generally required. It may actually cause more harm that good.  On larger sites, especially where SEO is not a primary concern, PageRank Sculpting could make a huge difference in how linkjuice flows through your site.

Here’s one example.

PR Sculpting using internal nofollow tags may be helpful for a site with extensive multiple layers of site navigation as part of the template for a site. (Think your entire sitemap on every page.)

The one example I’m thinking of right now has over 80 links in css based drops downs in the top navigation bar. Granted, there are over a thousand pages on the site, so it still only links to a small fraction of the overall pages.

If your site only has a handful of site wide navigation links, link sculpting isn’t for you. However, if you have multiple levels of CSS based dropdowns leading deep into your site, including to areas not very valuable in terms of search traffic, you may be a good candidate for internal use of nofollow.

Having a large quantity of deep links from every page on your site can only help, right? Well, maybe not. By linking to a large number of pages from your site template, you end up spreading your link juice very thin over your entire site, like peanut butter on bread. While that may be what’s best, sometimes that does more harm than good.

Instead of spreading your link juice thinly over a large portion of your site, you may be better off strategically directing a larger portion of your PageRank to certain pages by properly implementing nofollow on some internal links. We’ll get into that in future posts.

Is your site navigation like peanut butter on bread? Is it helping or hurting the PageRank flow within your sites?  This is like a sharp knife…sometimes it’s the best tool for the job, but if you’re not careful…it could hurt or kill your site.
