Strategic internal linking: boosting the authority of your key pages
Unlike backlinks, internal linking is an SEO lever you fully control, without depending on anyone else.
- An internal link passes part of one page's authority to another
- High-traffic, low-conversion pages are your best linking levers
- A descriptive link anchor always beats a “click here”
- No important page should be orphaned, without an inbound link from the rest of the site
What internal linking is and why it's crucial
Internal linking means the links you create between the pages of your own site. Unlike backlinks, which you don't control, it's a lever you fully steer. Its role is twofold: guiding visitors from page to page, and passing part of one page's authority to another.
When an internal link goes from a well-ranked page to a page you want to strengthen, you transfer part of its authority to it. This is especially powerful for your commercial pages: if a page attracts lots of organic traffic but converts poorly, well-designed linking can channel that traffic toward your service pages. Conversely, a conversion page that struggles to rank climbs faster when it's linked from already-established pages.
Good linking also has a technical benefit: it increases the likelihood that Google discovers and quickly indexes new or less visible pages, since they're connected to pages the crawlers already know well.
Prioritizing your key pages before linking
Not every page deserves the same treatment. First identify your “source” pages: those that already receive organic traffic or backlinks, and therefore have authority to redistribute. Then identify your “target” pages: your service or conversion pages that deserve to rank better. Internal linking means intelligently connecting the former to the latter, not adding links at random.
Linking techniques that work
- Descriptive anchors : link text that describes the target page helps Google as much as the visitor, far more than a “click here”.
- Contextual links : a link placed within the body of an article, relevant to the topic at hand, carries more weight than a link lost in a menu or footer.
- Silo structure : a pillar page that links to satellite articles, which all link to the associated service page, concentrates authority effectively.
- No orphan pages : every important page should receive at least one inbound link from another page on the site.
A redesign is the best time to rethink all internal linking from the design stage, rather than fixing pages one by one: this is what we build into every website design and redesign project.
Mistakes to avoid
Too many links on a single page dilutes the authority passed to each one: a few relevant links are better than twenty links buried in the text. Also avoid always using the same anchor for a given link, which can look artificial to Google. Finally, never overlook your service pages in this thinking: they're often the forgotten ones in linking, even though they're the most profitable destination.
Frequently asked questions
How many internal links per page?+
There's no magic number, but a few relevant, contextual links are better than a long list that dilutes the authority passed on.
Does internal linking replace backlinks?+
No, the two are complementary. Internal linking optimizes the authority already present on the site, while backlinks bring in new authority.
Should you redo the linking with every new article?+
Ideally yes: every new article should link to your existing key pages, and be linked from them if the topic lends itself to it.
