Frequently Asked Questions
What are internal links?
Internal links are links from one page of your site to another page on the same site. They connect your pages to each other, and building them well does two things: it spreads authority across your site, passing ranking strength between pages, and it helps search engines understand your site's structure and how pages relate. Internal linking is one of the most underused and valuable SEO tools.
How do you build internal links effectively?
Build internal links effectively by linking related pages to each other (connecting related content), using descriptive anchor text (clarifying what the linked page is about), linking to your important pages (spreading authority to the pages you most want to rank), and building a structure that connects your content (clarifying the site's organization). Maintained as you add content, this strengthens the site by spreading authority and clarifying structure.
Why do internal links matter for SEO?
Internal links matter because they spread authority across your site, passing ranking strength between pages, and they help search engines understand your site's structure and how pages relate. Strong internal linking strengthens your important pages by directing authority to them and clarifies your site for search engines. Poor internal linking leaves pages isolated and the structure unclear, missing these benefits, which is why internal linking is a valuable SEO tool.
What anchor text should you use for internal links?
Use descriptive anchor text that describes what the linked page is about, because anchor text gives context to both users and search engines. Descriptive anchor text clarifies the linked page's topic, helping search engines understand it, and helps users know what they will find. Avoid vague anchor text like "click here" that gives no context; instead, use text that describes the linked page's topic naturally within the content.
How many internal links should a page have?
There is no fixed number — the right amount of internal links depends on the page, its content, and what related pages are worth linking to. The goal is to link to relevant, related pages naturally where it helps users and connects your content, not to hit a specific number. Focus on relevant, useful links that connect related content and spread authority to important pages, rather than adding links for the sake of a count.
How does internal linking spread authority?
Internal linking spreads authority by passing ranking strength between linked pages — when a page links to another, it passes some authority to the linked page. By linking to your important pages from other relevant pages, you direct authority to the pages you most want to rank, strengthening them. This is why linking to important pages, and building a structure that connects your content, helps distribute authority across the site effectively.
