What is Site-Wide links In SEO?

A sitewide link is one that appears on most or all of a website's pages. A common area to see sitewide links is in the blogroll that is in the sidebar and appears on every page. You can also get sitewide links from being mentioned in the footer of a site if the site uses a template where the same footer is used for every single page.

Hi Friends,
Sitewide links are outbound links that appear multiple times throughout an entire web site or a section of a website. Typically these are links that appear in the footer, sidebar or navigation menu.
