How important is internal linking for digital agencies?

Very important — internal linking is one of the few on-page SEO levers you have complete control over. For digital agencies, the most impactful internal link structure routes authority from high-traffic pages (often the homepage) to your highest-value conversion pages (service pages, product pages, location pages).

How many internal links should a page have?

There's no fixed rule, but aim for 3–10 contextual internal links per page (excluding navigation and footer links). The most important rule: every important page should receive at least one internal link from a relevant, high-authority page.

What is anchor text and does it matter for internal links?

Anchor text is the clickable text in a hyperlink. For internal links, descriptive anchor text helps Google understand what the linked page is about. Use a mix of keyword-rich, topical, and natural anchors. Avoid over-using exact-match keyword anchors — aim for variety.

How do I find orphaned pages on my agencies website?

An orphaned page has no internal links pointing to it. Find them by running a site crawl with a tool like Screaming Frog or Semrush. Alternatively, check Google Search Console's Coverage report — pages that Google hasn't indexed often have no internal links. Fix by adding contextual links from relevant, related pages.
