I discussed the issue of nofollow distorting the web graph with a Googler and I was told that only about 1% of all links are nofollow.
It is hard to argue with a google employee, but at the same time, I can't help but feel that nofollow links make up significantly more than 1% of the websites that google INDEXES.
I am not saying he is lying, but something doesn't add up... Maybe people who work for google aren't very good at math? ;)
When I look at a backlink report for a site with "legitimate" links, nofollow links are significantly higher than 1%.
I am pretty sure that joomla and word press and other major CMS all have nofollow links, don't they?
and twitter uses nofollow links, as does facebook.
Aren't there tons of content farms along the likes of ehow? Aren't those links all nofollow?
Aren't all the external links on wikipedia nofollow?
Aren't there hundreds of thousands of blogs out there? Aren't those links (and the ones that appear in the comments) all nofollow?
granted, there are blogs that aren't monitored and have dofollow comment links, and granted there are spammers who exploit them like mad and cram thousands of dofollow links into those comments.
Maybe those nofollow links are countered by all the dofollow spam directories out there? Maybe they are countered by all the dofollow MFA sites that scrape google and bing search results? and yes, if you count Made-For-Links article sites, then they are full of do follow links.
But you would think that google would dismiss those kinds of sites from the link graph entirely?
I don't know... maybe someone just needs to hit me upside the head with a 2 X 4 for me to "get it", but I just find it really hard to believe that nofollow links only make up 1% of the link graph of the web.
The best products/websites generate a lot of buzz, which manifests itself in a vast amount of nofollow links in forums, blog comments, social media. And I really mean the best sites, they tend to have a lot of nofollow links.
Yes, that is what I am seeing, too.
