No SEO strategy is exactly the same, but there are core strategies that brands should use regardless of industry or category. Internal linking is one of them.
There are a few benefits to implementing an internal linking strategy:
Optimize internal links with relevant anchor text to clearly communicate the subject matter. If Google and the other search engines continuously see anchor text that is similar and that links to the same page, the chances of that page showing in search results for similar words are higher.
Internal links should be part of every SEO campaign because they are one of the factors within your control.
