What are sitewide links?
Most will already know this, but just to be clear, a sitewide link is one that appears on most or all of a website's pages. ... 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.
Sidewide links are those links that appear on every page of the website. We usually find it on header and footer section of the page. You could easily place sitewide links, or have sitewide links to your website placed on other websites.
