Internal Linking Strategy: Anchor Text, Site Architecture, and Link Equity Flow

Internal links do three jobs at once: they let readers move to related information, they let search engines discover pages, and they signal which pages the site considers important and what each page is about. Google says it uses links “as a signal when determining the relevancy of pages and to find new pages to crawl” (Google’s link best practices), and its ecommerce structure guide explains that “the more links a page has to it within a site, the higher the relative importance of the page to other pages on your site” (Google’s ecommerce site structure guide). An internal linking strategy is the deliberate design of those three jobs, based on what readers need, rather than a quota of links per page.

Principles from Google’s documentation

• Crawlable links: Google can generally crawl a link only if it is an <a> element with an href attribute.
• Every important page linked: “Every page you care about should have a link from at least one other page on your site”.
• Context: link to resources that “could help your readers understand a given page”, in context.
• No magic number: “There’s no magical ideal number of links a given page should contain. However, if you think it’s too much, then it probably is”.
• Descriptive anchors: good anchor text “is descriptive, reasonably concise, and relevant to the page that it’s on and to the page it links to”. Google warns against cramming keywords into anchors and suggests reading the anchor out of context to test whether it makes sense.
• Hierarchy: for ecommerce, Google suggests links “from menus to category pages, from category pages to sub-category pages, and finally from sub-category pages to all product pages”, and linking to important items from the home page or other content.

Link architecture

Three layers carry internal links:

Navigation and breadcrumbs also feed two search features: breadcrumb trails shown in results and the sitelinks Google chooses from a site’s structure.

Depth matters: Google mentions that the number of links needed to reach a page can inform its relative importance. Important pages should not sit many clicks away from the home page or be reachable only through deep pagination.

Anchor text

• Describe the destination’s topic: “how canonical tags handle paginated series” rather than “click here”.
• Vary anchors naturally when linking to the same page from different contexts; there is no need to repeat one exact phrase.
• Avoid generic labels (“this guide”, “learn more”, “our services”) that say nothing about the destination.
• Keep anchors concise; the surrounding words also provide context, which Google’s guidance mentions.

“Link equity” in practice

Google’s ranking systems guide says PageRank, a link analysis system, “continues to be part of our core ranking systems” (Google’s ranking systems guide). How internal links distribute value is not published in detail. Practical consequences that do not depend on unpublished mechanics:

• pages with many relevant internal links are signaled as more important;
• pages linked only from the sitemap or from deep archives are signaled as less important;
• links to redirects or 404s waste a reader’s click and add crawl overhead;
• nofollow on internal links is not a sculpting tool. Google’s guidance on qualifying outbound links says that for links within your own site, use robots.txt disallow if you need to prevent Google from fetching a page (Google on qualifying outbound links).

An internal linking audit

1. Crawl the site from the home page and export, for every URL: inlinks count, crawl depth, and the anchor texts of inlinks.
2. List important pages (high business value, high search demand) and check their inlinks and depth.
3. Find orphans: pages in the sitemap or CMS but not reached by the crawl.
4. Find broken and redirected internal links.
5. Review anchors for generic or misleading text.
6. Check hubs: does each topic hub link to all its child pages, and do children link back to the hub and to related siblings where useful?

A redesign example

Consider a hypothetical home improvement site with 400 articles organized only by publication date.

Audit findings (illustrative):

• the site’s highest-converting guides sit at crawl depth 6 to 8, reachable only through blog pagination;
• 70 articles have no internal links from other articles;
• 120 internal links point to redirected URLs from an old migration;
• anchors are mostly “read more” and “this post”.

Redesign:

• create topic hubs (roofing, plumbing, electrical, flooring), each listing and briefly describing its articles;
• add the hubs to main navigation;
• add two to five contextual links in each article to closely related articles, where they help the reader;
• replace links to redirects with links to final URLs;
• rewrite generic anchors to describe destinations.

Verification: check that a new crawl shows priority guides at depth 2 or 3, no orphans among current articles and no internal redirects; then watch Search Console for the hubs and priority guides being crawled and, over time, earning impressions.

Limitation: better internal linking improves discovery and signals importance; it does not guarantee rankings for any page.

Linking patterns to avoid

• Fixed link quotas per article.
• Sitewide footer blocks of keyword links.
• Linking every mention of a keyword to the same page.
• Circular linking schemes built for link counts rather than readers.
• Using nofollow to manage internal flow.

Keeping the structure intact as the site grows

Add internal linking to the publishing workflow: every new page receives links from at least one relevant existing page and links out to its hub and related pages, and the content inventory records each page’s hub.
