How internal linking helps SEO

Four ways internal links help

1. Discovery. Search engines find pages by following links. A page with no internal links pointing to it may be found slowly or not at all.

2. Context. The clickable text of a link (anchor text) tells search engines what the target page is about. "Read about our technical SEO service" says far more than "click here".

3. Importance. Pages that receive many internal links — especially from strong pages like your homepage — are signalled as important.

4. User journeys. Links move readers from learning to deciding: from a blog post about a problem to the service that solves it.

Good and bad anchor text

Keep anchors natural and descriptive. Do not force exact-match keywords into every link.

Linking patterns that work

• Hub and spoke: a main service page links to its sub-services; each sub-service links back to the main page.
• Blog to service: every helpful article links to the relevant service.
• Service to industry and location: service pages link to industries and locations where the service matters, and vice versa.
• Related reading: articles link to closely related articles.

This website uses all four. Notice how this post links to services and to the internal linking strategy guide.
