Should Wikipedia/Wikimedia deserve a spam report?A shady story of power and "link juice"
Grab some popcorn, I'll tell you a story...
In April 2015 Wikipedia Italia published a banner at the top of every page, asking Italian users to donate a percentage of their taxes to Wikimedia Foundation. This is nothing new or unusual. This banner is still online, as I write this post.
The banner has a link to a landing page: http://landing.wikimedia.it/
Still, nothing strange or wrong with the page itself but
at the bottom of this page there is a completely unrelated keyword-rich link
that points to the home page of a web agency. Its anchor text is the competitive Italian keyword "realizzazione siti web" ("website creation").
Now, I remember you, this landing page is linked from every freakin' article of the Italian encyclopedia
, so I suspect that Google should assign to it a bit of importance.
I discovered the link only at the end of April, and I started monitoring the position of the home page of that web agency for the query [realizzazione siti web]. You can observe the rankings in the attached image.
Currently, the page ranks at the 35th position and it best position, since I started monitoring it, was 20. These results are nothing spectacular, but
we don't know in what position the page ranked before
being linked by the Wikimedia landing page.
So, now I'm waiting for Wikipedia to remove the banner, an action that should slowly change the position of the web agency home page to the position it occupied before being indirectly
pushed by every freakin' page of the encyclopedia
I admit that I'm a bit pissed off, but I'll learn a few things from this event and I think that it could be an interesting case study to understand how much a single page, while important, can actually influence the rankings.
My prediction is: not very much. But we'll see.
The above considerations don't take in account other factors: the position of the link in the page being the first and the quantity of other links in the page to be the second.
