I never heard about Knol until my friend referred me to the site. As soon as I entered the homepage, all I recognize was the concept of Wikipedia, which allows everyone to write a page on a specific issue. The title says “Knol: A Unit of Knowledge”. For any blogger who interested on building backlinks, This might sound interesting since you can take part by writing any articles that you know and put a link right to your blog. But unfortunately, you need to look up the page source and spot the meta robots that stated the pages are indexed but all the outbound links are nofollowed.

The nofollow tag here means that links you put in the Knol’s page will not count as a referrer to your site for the PageRank calculation. Again, it’s only affect the site’s Pagerank, not the your site itself. Knol is starts to grow into a trustworthy source of content. In this case, any blogger can use Knol as the entry page for the specific niche that they cover on their blog. They could use the article tactics to promote their blog as well as they usually did on ArticlesBase, iSnare, or ArticleAlley. Writing a page on Knol can establish someone’s authority on specific field.

The advantage of Knol is that they’re ranked specifically on Google’s SERP, since they are one of the Google’s property. Danny Sullivan from Search Engine Land has been conduction some tests with Knol pages, and the results are surprising. 30% of all the Knol pages that he created for test pages were ranking on the first page of Google’s results after one day.

The SEO master, Aaron Wall also proved that with some backlinks involved a Knol page that duplicates a page of an existing web page will outrank the original.

I haven’t tried it, yet but I’m sure they will provide a good contribution to my blog if I can use it properly. Are you interested?
