Internal Linking: The Ranking Lever You Control Completely

The lever nobody can take away from you

You cannot force another site to link to you, and you cannot make Google's algorithm behave. Internal links are different: you decide where every one goes, what its anchor text says and which pages receive the most. They pass authority around your site, tell Google which pages matter and what each is about, and guide visitors towards the pages that make you money. For most small business sites, they are also the most neglected asset available.

The neglect shows up in familiar patterns: service pages buried three clicks deep, blog posts that link to nothing, and important landing pages no other page mentions at all. Fixing these costs nothing but time, needs no developer on most content management systems, and often moves rankings within weeks because Google recrawls and re-evaluates as it follows the new links. Unlike a backlink campaign, there is no outreach, no waiting on strangers and no budget beyond attention.

The free-tools audit workflow

You can run a competent internal link audit without spending a pound. Work through this sequence:

• 1. Crawl your site with Screaming Frog's free tier (up to 500 URLs, enough for most small sites) and export the inlinks data to see how many internal links each page receives
• 2. Open Google Search Console's Links report and compare the 'internally linked pages' list against the pages you actually want to rank
• 3. Sign up for Ahrefs Webmaster Tools, free for your own verified site, and run its Site Audit for internal link opportunities suggested from your existing content
• 4. Compare the crawl results against your XML sitemap: any URL in the sitemap the crawler never found through links is an orphan page
• 5. Note anchor text as you go; Screaming Frog's inlinks export shows the exact anchor used for every link

The output you want is a simple sheet: page, links in, links out, anchors used, and a priority flag against every money page that is under-linked.

Orphan pages: traffic you already paid for

An orphan page has no internal links pointing to it. It might still be indexed via the sitemap, but Google treats it as unimportant because your own site treats it as unimportant. Orphans are common after redesigns, migrations and years of blog publishing: the page exists, ranks for little, and quietly wastes the effort that went into creating it.

For each orphan, make one of three decisions: link it, merge it or remove it. If it targets a query you care about, add links from at least two or three relevant pages, including one strong page. If it duplicates a better page, merge the content and redirect. If it is genuinely obsolete, remove it with a 301 redirect to the nearest relevant page. Leaving orphans in place is choosing to leave rankings on the table.

Anchor text: descriptive, varied, honest

Anchor text is one of the clearest relevance signals you control. Google reads the linked words as a description of the destination page, so vague anchors throw that signal away.

• Describe the destination: 'boiler installation costs' beats 'read more' or 'this article' every time
• Vary the phrasing across links; five identical exact-match anchors pointing at one page looks manufactured, while natural variations do not
• Keep anchors honest: the linked page must deliver what the anchor promises, or visitors bounce and the signal sours
• Link from within body copy where possible; in-content links carry more weight than footer or sidebar boilerplate
• Prioritise a handful of meaningful in-content links per page rather than exhaustively linking everything to everything

One habit worth building: when you publish a page targeting a new phrase, search your own site for that phrase using the site: operator to find every existing mention, then turn the best mentions into links. It is the fastest way to find natural linking spots, and the surrounding language is already contextual.

A worked scenario: rankings moved by links alone

Consider a pattern that turns up constantly in audits. A ten-year-old trades site has a 'bathroom fitting' service page sitting at the bottom of page two. A crawl shows it receives two internal links, both from the footer. Meanwhile the blog contains nine posts about bathroom renovations, tiling and wet rooms, and not one of them links to the service page.

The fix takes an afternoon: an in-content link from each relevant post using varied descriptive anchors ('bathroom fitting service', 'professional bathroom installation', 'our bathroom fitters'), a link from the homepage's services section, and links between the blog posts themselves. No new content, no backlinks, no technical changes. When Google recrawls, the page's internal authority and topical context have both changed materially, and pages in this situation frequently climb as a result. It is the cheapest experiment in SEO, and it belongs before any spend on link building or new content.

Make linking part of publishing, not a yearly rescue

Audits decay. The durable fix is a rule set applied to every new page before it goes live:

• Every new page receives at least three internal links from existing relevant pages within a week of publishing
• Every new page links out to at least two relevant existing pages, one of them commercial
• Anchors are written by hand and describe the destination
• Money pages are reviewed quarterly: are they still among the best-linked pages on the site?
• The crawl is rerun twice a year to catch new orphans before they age
