What are they?
- Internal links are hyperlinks that connect two pages on the same domain together.
- They can take many forms, such as text links, image links, navigational links, and more…
Why are they important:
- Search engines use internal links to understand how website authority (also known as ‘pagerank’) is distributed across a website.
- In a very general sense, the more internal links pointing to a page, the more important it is to a search engine.
How it works:
- A website accrues pagerank from the quantity and quality of external links pointing to it’s pages (typically, the homepage holds the most pagerank of all pages on a website).
- Pagerank then ‘flows’ between pages through internal links; as one page links to another, pagerank is transferred from the linking to the linked page. This gives each page a ‘score’ – the higher the score the more pagerank a page holds.
- As with external links, not all internal links are equal; a link from the homepage will transfer more pagerank than a link from a blog page, for example.
