What is internal linking?
Also called: internal links, site structure
Definition
Internal linking is linking from one page on your site to another page on the same site. It helps visitors and crawlers find pages and tells search engines which pages matter and what they're about.
Internal linking, explained
Search engines discover most pages by following links. Google's link guidance says every page you care about should have a link from at least one other page on your site. A page that nothing links to, an orphan page, may never be found, or may be crawled rarely and judged unimportant.
Internal links also carry meaning. The anchor text, the words you click, tells Google what the target page is about. A link that says "compare launch platforms" is more useful than "click here". And pages that receive many internal links from important pages, like your homepage or a popular guide, are treated as more important.
For links to count, crawlers must be able to read them. Google can reliably follow an <a> element with an href attribute. It can't reliably follow links that only exist as JavaScript click handlers or buttons that change the URL with script. In React frameworks, use the framework's link component, which renders a real <a href>.
A practical structure for a startup site: a small set of hub pages (features, pricing, blog, tools, glossary) linked from the navigation and footer. Each hub links down to its detail pages. Detail pages link back up to their hub and sideways to closely related pages. New pages get linked from at least one existing page that Google already crawls often, which is usually the fastest way to get them indexed.
Programmatic pages depend on this more than anything. Hundreds of pages linked only from a sitemap tend to index slowly. The same pages linked from relevant hubs and from each other index faster and rank better.
Why it matters for founders
You control internal links completely, and they cost nothing. For a new site with few backlinks, they're the main way to tell Google which pages matter and to get new pages crawled.
Example
You publish a guide to directory submissions. You link to it from your blog hub, from your pricing FAQ, and from the glossary entry for "directory submission" with the anchor text "how to choose directories".
Common mistakes
- Orphan pages that exist only in the sitemap.
- Generic anchor text like "read more" everywhere.
- Links rendered as buttons or JavaScript handlers that crawlers can't follow.
- Stuffing dozens of exact-match keyword links into a footer.

- Anchor textAnchor text is the visible, clickable text of a link. Search engines read it as a description of the page being linked to, so clear, specific anchor text helps both readers and rankings.
- Topic clusterA topic cluster is a group of pages about one subject: a broad pillar page linked to several detailed pages on subtopics, which link back. It shows readers and search engines the depth of your coverage.
- BacklinkA backlink is a link from another website to yours. Search engines use backlinks to discover pages and as one signal of which pages are trusted and worth ranking.
- Programmatic SEOProgrammatic SEO is creating many search-targeted pages from structured data and templates, such as one page per integration, city or comparison. It works when each page answers a real query with unique, useful data.
