Penguin Looks At The Page Backlink Source
Another story I wrote on SEL based on the interview I did with Gary Illyes from Google was that Google Penguin is mainly a link spam algorithm and it works by linking most to the source of the link.
In short, and I think most SEOs understand this already, Penguin looks at the page linking to your site. If this page is really bad, it can be called a penguin link.
Some SEOs may have confused connections as just the anchor text or URL. But when I look at the concept that Google calls Penguin a “web spam algorithm” and specifically not a “link spam algorithm” – Gary said this is the reason why – looks at the source of the link coming from.
Google Penguin looks at the source site, not on the target site, he said in the interview. It is not the goal of the connection, but the source of the connection.
One example he gave of a link source that could be beaten with a penguin label is a source page that has a low quality forum profile page that links to you. He said, “blank profile pages, forum profile pages” could be an example.
