Subdomains

The internal link analyzer is able to recognize subdomains and treats them as internal links. If a link points to a subdomain this will be visible under link type “subdomain”. Watch the video from Google’s web engineer, Matt Cutts regarding the use of subdomains.

Best practices internal links

• Number of links: Back in 2008, Matt Cutts (head of Google’s Webspam team) recommended limiting the number of links to a maximum of 100 links per page. Today (since 2013) Matt Cutts explained having more than 100 links per page isn’t an issue, and this limitation is dropped from Google Webmaster Guidelines.
• Duplicate links: Try to limit the number of duplicate links. If you get a high percentage of duplicate links (>50%) you’re not spreading your link strength effectively.
