As we have all heard, Wikipedia has placed “nofollow” tags on their outbound links. This was greeted with a fair amount of dismay by the SEO and Webmaster world at large, as well it should have been.
But it turns out that Wikipedia links still have great value. Why? Because other people go to Wikipedia pages and then link to the sites that Wikipedia links to.
In a non-scientific examination of some of the sites we work with, we have seen Wikipedia links result in a significant number of additional links. One site we know regularly gets 20+ additional links for every Wikipedia link they get. Best of all, these are relevant links.
So don’t lose all interest in Wikipedia yet. Links there can still help your site.
