On 15 June 2009, one of the most important changes occurred in the SEO field. Matt Cutts (head of Google`s Webspam team) announced that Google no longer treats nofollowed links (<a rel=”nofollow” href=`…`>) in the same way.
In this article we will explain what PageRank Sculpting is and what changed in Google`s Algorithm. Briefly we will suggest a PR Sculpting technique that is analyzed in the article “PageRank Sculpting: You can still use nofollow“, thus experienced SEO Engineers should read directly that article.
Mainly in this blog post we will try to answer the following questions:
- What is PageRank Sculpting?
- What changed in Google`s algorithm?
- Is it still possible to do PageRank Sculpting? Can we use nofollow? (Yes we can)
Google more or less used to discourage the PageRank Sculpting techniques. From their point of view the SEOs were messing with their algorithm. In their documentation, in several events and in some blog posts they mentioned that they do not suggest using those techniques because a) they are not as effective as we think (they are time consuming), b) in some cases they can do more harm than good (nofollowing by mistake important information that users need to find).
Let’s see briefly what PageRank Scuplting is:
What changed in Google‘s algorithm?
Important Notice: The PageRank value that you see on Google toolbar is not the real rank. The actual score is not revealed by Google. Generally we consider that the toolbar scale is more or less logarithmic.
Let`s see how Google used to treat nofollow attribute at the beginning.
Suppose that you have a site with 4 pages. The homepage has 6 points of actual PageRank and there are 3 links that point to the internal pages. By using the original PageRank each internal page will receive 6/3=2 PageRank.
In the past if we blocked a link with nofollow, the 2 followed pages would get the PageRank of the blocked page.
Unfortunately now Google handles nofollow attribute in a different way. By nofollowing the first page it still gets PageRank 0, BUT the other 2 pages gain no PageRank. This causes a PageRank loss. See the image below:
Is it still possible to do PageRank Sculpting? Can we use nofollow? (Yes we can)
Matt Cutts mentioned in his blog that “More than a year ago, Google changed how the PageRank flows…“. I partially agree with the above as I am positive that in the last year wherever we used the nofollow attribute we saw good results. Perhaps the results were not as good as they used to be on the past, but still the websites that used PageRank Sculpting techniques had better PR flow than the ones that did not. But that’s not the point.
So we could say that rel=`nofollow` was a tool that was generally used for this purpose because of its simplicity. Thus the problem in these days is that the SEOs lost one of the most useful tools for PR Sculpting.
Or they did not?
The solution that WebSEOAnalytics suggests is a little bit tricky but very easy to implement and reliable. What if we continue using the nofollow attribute in our code and just before we send the HTML page to the user we convert the nofollowed links into something else?
- Recursive Function Calls
- The HTTP POST method
- Base64 Encoded URLs
The webSeoAnalyticsLinker helps you to continue using the rel=`nofollow` attribute in your code and be able to perform PageRank Sculpting in the way you did before. It can be installed in every site with minimal effort and solve the rel=`nofollow` problem once and for all.
