I have a bunch of websites with recipes from around the world. On the footer of each one of them there are links to the others.
I was wondering if this technique is good or not for SEO. I own all of the websites and Google knows about it (they all are in Google Webmasters).
Also, having the backlink in the footer means that it is in literally every single page. Does that affect as well? Is it better to have a backlink just in one or two pages?
