- 0 – Money from the Web – 0 – The Reality Show

A few years ago to combat blog comment spam, the search engines implemented no follow backlinks. This changed strategies for both big business and small business SEO. The links with the no follow attribute were thought to have little to no value because they don’t pass link juice, or PageRank (PR) to the linked to site. Now, it things appear to have changed.

SEOMoz recently reported in their 2011 ranking report that a correlation exists between ranking and the presence of no follow links.It seems that the search engines are looking at the ratio of do follow links to no follow links. If there are too many do follow links, the link profile appears to be unnatural. The search engines expect that in the normal course of link getting, links from both do follow and no follow sites are normal.

So, if you look at your site link profile and it has a high ratio of do follow links, you need to go to no follow blogs, social media bookmarking sites and other sources of no follow links to improve the profile.

What About Authority?

It’s probably true that PR is not passed with a no follow link. . That may or may not be the case, but let’s say it is. My question has been for some time now, even if no PageRank is passed, is a link from an authority site related to the linked to site valuable?

Many SEO specialists and teachers have been saying for years to ignore the no follow attribute. They say is a link is a link and their testing shows it doesn’t seem to matter whether it’s no follow. I’m wondering out loud, if link juice is not passed through PR, are other signals being used to determine authority and relevance.

Search Engine Algorithms

For a lot of reasons, search engines are designed and tweaked to provide the best result for search queries. The algorithms look at off page and on page factors. We’ll look at off page factors. A link from a site provides a vote to the destination site. If the link is no follow, the PageRank (PR) is gone, but I’m thinking other signals in the algorithm are present that make the link from an authority site valuable.

With Google stating that there are over 200 signals in the algorithm, and others saying it’s many more, why wouldn’t they be including the relevance of the link in relevance factors.

Let say that two sites have content that is of the same quality. There’s nothing to choose between them. Based on on page factors, it’s a dead heat. Still, one ranks higher than the other. Why?

On site factors are the same, so the ranking must be based on off site factors. These sites have the same PageRank profile. Each has 500 links with the same anchor text, the same PR profile and the same distribution of do follow and no follow links.

I am submitting that where the links come from is an overlooked factor. If the first site’s links are mostly from sites related to the content, while the second site get its links from general or non-related sites, the first site will rank higher. I don’t think many would argue the value of relevance, but I’m firmly suspecting that no follow links are passing relevance signals even if they’re not passing PR.

A New Life for No Follow Links?

So, just maybe, no follow links have value after all. How much we don’t know for sure, but if the engines know it’s no follow and still record the signal, there’s go to be one or more reasons. We believe there’s a link profile signal. The question is, are there relevance signals in the algorith for no follow links? I do not advocate ignoring the value of the do follow link, but it appears that in our SEO and local SEO programs, we need to pay attention to assuring we have good quality no follow links too.

As I was out strolling the web this evening my attention was drawn to another web basic that I had not specifically discussed in the Website Basics section. I had a page on navigation, but basic to navigation is the link system. I wrote up an article on the topic and posted it to the Website Basics section this evening. I expect to find a few more topics and I am soliciting suggestions for basic topics that I have not covered.
