Most guides on internal linking tell you to “add contextual links between related pages”. Useful, but it leaves out the part that actually moves rankings: which pages should you link from first, and where should that authority land?

If you add internal links at random, you spread link equity evenly across a site that does not deserve even treatment. Your comparison page, your pricing page, your service page and your highest-margin category page are the pages that pay the bills. Your blog posts are the pages that collect backlinks. An internal linking strategy for SEO is simply the plumbing between the two.

This guide gives you a prioritisation framework based on real data (Search Console clicks, referring domains, crawl depth) plus nine rules you can apply the same afternoon.

What internal linking does (short version)

Internal links are links pointing from one page of your domain to another page of the same domain. They do three jobs:

• Discovery and crawling: Google finds and re-crawls URLs through links. Pages with few or no internal links get crawled rarely, or not at all.
• Authority distribution: PageRank-style value acquired through external backlinks flows through internal links. A page with 40 referring domains can share that strength with the pages it links to.
• Relevance and context: Anchor text and surrounding copy tell Google what the destination page is about, and how pages relate inside a topic cluster.

Point three is why internal linking is not just a technical hygiene task. Point two is why it is one of the cheapest SEO wins you have: you already own the authority, you are simply routing it badly.

First, define your money pages and your donor pages

Before touching a single link, split your URLs into two lists. The piece Internal links: ultimate guide + strategies makes a good next read.

Page type	Examples	Role in the strategy
Money pages	Service pages, product and category pages, pricing, demo requests, high-intent comparison pages, local landing pages	Receive links. They rank for commercial keywords and generate revenue.
Donor pages	Blog posts, guides, glossaries, free tools, studies, news posts	Send links. They attract backlinks and informational traffic but rarely convert directly.

Keep the money page list short. Ten to twenty five URLs is enough for most sites. If everything is a priority, nothing gets enough links.

Build your prioritisation sheet in 30 minutes

This is the step most internal linking tutorials skip. Export four data points into one spreadsheet, one row per URL:

1. Clicks and impressions (last 3 months) from Google Search Console.
2. Referring domains per URL from your backlink tool of choice (Ahrefs, Semrush, Majestic, or your own link records).
3. Existing internal links in from a crawl (Screaming Frog, Sitebulb, or the Links report in Search Console).
4. Crawl depth (number of clicks from the homepage) from the same crawl.

Then score your donor pages. A simple weighting that works well:

Signal	Why it matters	Weight
Referring domains to the URL	Direct measure of the authority available to pass on	50%
Organic clicks to the URL	Real users who can click through to the money page	30%
Topical closeness to the money page	Relevant links carry more weight and convert better	20%

Sort descending. The top 20 rows are your first internal linking sprint. A single well-placed link from a post with 30 referring domains beats forty links from thin pages nobody visits and nobody links to.

The 9 rules of an internal linking strategy that moves revenue

Rule 1: Link from your strongest donors first, not from your newest posts

The default behaviour is to add internal links while publishing new content. New posts have zero backlinks and zero authority, so those links pass almost nothing. Reverse the order: start with the pages that already earned links and traffic, and add a contextual link to the relevant money page from each one.

Practical target: every money page should receive at least 3 to 5 links from pages in your top authority quartile.

Rule 2: Keep money pages within three clicks of the homepage

Crawl depth correlates with how often Google re-crawls and how much internal equity a page accumulates. If your key service page sits five clicks deep behind a paginated blog archive, fix the structure before optimising anchors.

• Depth 0: homepage
• Depth 1: main navigation categories and top service pages
• Depth 2 to 3: sub-services, product pages, priority comparison pages
• Depth 4+: acceptable only for archive content and low-priority URLs

Quick wins to reduce depth: add a curated “popular services” block in the footer, link money pages from your most-visited blog posts, and replace infinite pagination with hub pages that link to individual posts.

Rule 3: Place the link inside the body copy, high on the page

Contextual links inside a paragraph outperform links stuffed into a footer or a sidebar widget, both for click-through and for the relevance signal they send. Where possible, put the link to your money page:

• inside the first half of the article, ideally after the section where the reader realises they have a problem you solve;
• surrounded by relevant text (the sentence around the anchor is part of the signal);
• as a normal <a href> tag in the HTML, not a JavaScript event that only fires on click.

Rule 4: Vary anchor text, but keep the target keyword recognisable

Internal anchors are one of the few ranking signals you fully control, which is exactly why identical exact-match anchors repeated 60 times look manipulative and stop adding value. Use a distribution instead:

Anchor type	Example (target: “SEO backlink service”)	Suggested share
Exact match	SEO backlink service	20 to 30%
Partial match / variation	our backlink building service, buy quality backlinks	40 to 50%
Long tail / question	how we build backlinks for clients	15 to 25%
Branded or natural	DigBacklink, see the pricing here	10%

Two extra habits that matter: never use “click here” as your only anchor to a commercial page, and make sure the anchor text still reads naturally out loud. If you would not write that sentence for a reader, do not write it for Google.

Rule 5: One link per destination, per page

When a page contains several links to the same URL, Google generally uses the first anchor and ignores the rest for anchor purposes. Multiple links to the same target also dilute the equity split of everything else on the page. Pick the strongest sentence, link once, and use the remaining link slots for other destinations.

Rule 6: Control the total number of outgoing internal links

There is no hard limit, and Google dropped the old “100 links per page” guideline years ago. But equity is divided among links, so a page with 250 links passes very little through each one. Practical guardrails:

• Blog post: 4 to 10 contextual internal links, of which 1 or 2 point to money pages.
• Category or hub page: as many as the layout genuinely needs, but avoid mega-menus repeating every URL on every page.
• Money page: keep outbound internal links focused. Do not send visitors back into the blog from the middle of a sales page.

Rule 7: Kill orphan and near-orphan pages

An orphan page has zero internal links pointing to it. A near-orphan has one, usually from a sitemap or an archive page. Both waste crawl budget and any backlinks they hold.

1. Crawl the site and cross-reference the crawl with your XML sitemap and GSC-indexed URLs. Anything in the sitemap that the crawler never reached is an orphan.
2. For each orphan, decide: link it, merge it, or remove it.
3. Link it if it has traffic, backlinks or commercial value. Add 2 to 3 contextual links from relevant existing pages.
4. Merge it with 301 redirects if a stronger page covers the same topic.
5. Remove or noindex thin tag archives, old promotions and duplicate paginated URLs.

Special case worth checking: orphaned pages that hold backlinks. Those are free authority sitting behind a locked door. Reconnect them and route them toward a money page.

Rule 8: Stop leaking equity into low-value URLs

Every sitewide link to a page nobody needs to rank (login pages, empty tag archives, endless filter combinations) takes a share of what your templates distribute. Instead of scattering nofollow everywhere, which mostly wastes the equity rather than redirecting it:

• Remove template links to URLs with no search or conversion purpose.
• Block crawlable filter and sort parameters with robots rules where appropriate.
• Consolidate near-duplicate archives into a single hub page.
• Replace footer link dumps with a short, curated list of your priority pages.

Rule 9: Measure the result, then run the next sprint

Internal linking is measurable. Record a baseline before you start and check it 4 to 8 weeks later:

• Average position and impressions of each money page (Search Console, page-level filter).
• Internal links count per money page (crawl or GSC Links report).
• Crawl depth of money pages.
• Assisted conversions or clicks from blog to money page (analytics event or UTM on internal link where relevant).

Then repeat the prioritisation sheet each quarter. New backlinks land on new posts, so your donor ranking changes over time. A good rhythm is a quarterly internal linking sprint of two to three hours for most sites.

A 90-minute workflow you can run today

1. 0 to 15 min: list your money pages (max 25 URLs) and note the primary keyword for each.
2. 15 to 40 min: export GSC clicks and referring domains per URL, build the donor score, sort descending.
3. 40 to 60 min: for the top 20 donor pages, find the natural mention of the money page topic (site search: site:yourdomain.com "keyword").
4. 60 to 80 min: insert one contextual link per donor page, using varied anchors from the table above.
5. 80 to 90 min: log everything in the sheet (date, source URL, target URL, anchor) and note the baseline metrics.

That log is what turns internal linking from a vague chore into an auditable asset. It also stops two team members from linking the same post twice with the same anchor.

Mistakes that quietly cap your results

• Linking only from new content. Zero-authority sources, minimal effect.
• Sitewide sidebar links to the same money page. Google largely discounts boilerplate; contextual beats template.
• Identical anchor text everywhere. Looks engineered and wastes the chance to cover keyword variations.
• Linking to redirected or 404 URLs. Every redirect hop and dead link is friction. Fix targets to their final URL.
• Ignoring the reader. A link that makes no sense in context earns no clicks, and click behaviour still matters for conversions even if you argue about its ranking role.
• Forgetting mobile. If your internal links live in a collapsed block that mobile users never open, they still count for crawling but do nothing for revenue.

How internal linking multiplies your backlink budget

Here is the part worth internalising if you invest in link acquisition. When you earn a backlink to a guide, the value does not stop at that guide. It flows onward through whatever internal links that guide contains. So the same backlink can either:

• sit on a blog post that links nowhere useful, or
• push part of its strength into the page that sells your product.

Same cost, very different return. Before buying the next batch of links, spend ninety minutes on the plumbing. Then every new referring domain you acquire lands in a structure that carries it toward revenue instead of dead-ending in an archive.

FAQ

What is the best internal linking strategy for SEO?

Link from your highest-authority, highest-traffic existing pages to a short list of commercial pages, using varied and descriptive anchor text, keeping those commercial pages within three clicks of the homepage, and fixing orphan pages. Prioritise by referring domains and organic clicks rather than adding links at random.

How many internal links are too many?

There is no fixed limit, but equity is split between links. For a standard blog post, 4 to 10 contextual internal links is a good range. Navigation and footer templates repeating hundreds of links on every page dilute value and should be curated down.

What are the best internal linking tools?

Screaming Frog or Sitebulb for crawl depth and orphan detection, Google Search Console for clicks and the internal Links report, Ahrefs or Semrush for referring domains per URL, and a simple spreadsheet to score and log everything. Plugins such as Yoast or Link Whisper can suggest link opportunities, but always validate suggestions against your priority list.

Do internal links really pass authority?

Yes. Internal links distribute PageRank-style value across your site and carry anchor text relevance. That is why a link from a page with dozens of backlinks is worth far more than a link from a brand new post.

How often should I audit internal links?

Run a full audit twice a year and a shorter prioritisation sprint every quarter, plus a check any time you migrate, redesign, prune content or acquire a batch of new backlinks.

Should internal links be nofollow?

Almost never. Internal nofollow generally wastes equity rather than redirecting it. If a page should not be crawled or ranked, remove the link, consolidate the page or handle it with robots and canonical rules instead.

What is a good internal link count per money page?

Aim for at least 10 internal links total, including 3 to 5 from strong, topically relevant donor pages. Track this number per URL and treat it as a KPI alongside rankings.
