Websites link to others from various places on their site, but are all links created equally?
The answer – according to Google – is no.
Google’s John Mueller summarised in this Google Webmaster hangout from 2016, that having links to or from your site within the main body of the text is classed as primary content.
However linking to or receiving links from other sites from boilerplate (footer, sidebar, etc) locations may carry less weight.
That’s because these links can be viewed as less important in the eyes of Google, when compared to primary in-content links.
There is a difference, so bear this in mind when reviewing the location of incoming links to your site in future.
