Connect the next useful piece of information
Internal links help readers move between related content on the same website. Navigation and breadcrumbs explain the broad structure; contextual links answer a more specific need at the point it arises. A service page can link to an explanation without interrupting its commercial message with every technical detail.
Google can most reliably crawl links implemented as anchor elements with href destinations. Link text should describe the destination naturally. Google’s link guidance covers crawlable markup and descriptive anchor text.
Example: linking a service page to a glossary term
Suppose a website hosting page discusses DNS changes during migration. Linking the first useful mention of DNS to its glossary page gives a less technical reader an explanation. That glossary page can then point to DNS management and related concepts such as domain names and email deliverability.
The links serve different purposes: one explains a term, another helps someone find professional assistance. Their wording should make that distinction clear. Repeating the same glossary link after every occurrence of DNS adds clutter without helping the reader choose a next step.
Checks for a growing website
Make sure important pages have a route from a relevant hub or related page. Review links when URLs change and update them to the final destination, avoiding unnecessary redirect chains. Check links inside reused builder templates as well as ordinary paragraphs.
Do not automatically link every keyword to a sales page regardless of context. A phrase describing an educational concept should lead to the promised explanation. Nor should every page receive the same long block of unrelated links. A useful internal linking plan reflects the relationships between subjects and gives readers a manageable set of choices.
Common questions about internal link
How many internal links should a page contain?
There is no universal target. Add links where the destination helps the reader understand a concept, compare a relevant option or take an appropriate next step.
Can internal links replace the main navigation?
No. Contextual links complement navigation. Visitors still need dependable access to major sections, particularly when they enter the website through an individual glossary or service page.
