Link Strategy: Internal and External

In 2026, links are a trust signal, not a numbers game — internal as well as external. They show search engines which pages belong together, which are important, and whom you trust. A good link strategy spreads relevance where it counts and collects earned recommendations instead of bought ones. In more than 25 years I have seen both sides: projects that took off with a few clean internal links, and ones that catapulted themselves out of the index with purchased backlinks. This article deepens the link pillar from SEO in 2026: What Actually Matters.

Internal and external linking at a glance

In short: internal linking is fully under your control, external links and backlinks only partly — and that is exactly why the internal lever pays off first. The table places the most important building blocks.

Link type	What matters
Internal links	descriptive anchors, spread relevance, help crawling
Anchor text	meaningful instead of "click here"; names the target topic
External links	point to reputable sources; signal authority
rel attributes	`nofollow`, `sponsored`, `ugc` for paid and user-generated links
Link depth	important pages ≤ 3 clicks from the homepage
Backlinks	quality over quantity; topically relevant and credible
Broken links	404s waste crawl budget and user trust

Anchor text and internal linking

The anchor text is the context you hand to search engines and readers — use it. Link with meaningful text like "SEO fundamentals" instead of "click here"; both humans and crawlers then understand it immediately. Internal linking is your strongest lever precisely because it is fully controllable: link related pages from within your body text, because that spreads PageRank deliberately to important content and helps crawlers find new pages at all. I treat internal linking as an editorial task, not a technical chore — every new article should deliberately point to two or three topically fitting existing pages.

External links and rel attributes

Linking out is not a risk but a quality signal — pointing to reputable sources shows judgment instead of secrecy. What matters is correct labelling: paid links get rel="sponsored", user-generated content like comments rel="ugc", and generally not-endorsed targets rel="nofollow". These attributes are not a vote of no confidence but honesty toward search engines about how a link came to be. Setting all external links blanket-nofollow, by contrast, throws away the chance to position yourself as a reliable source through good references.

Link depth and broken links

Picture a crawler starting on your homepage and clicking through: what it does not reach in three clicks, it sees less often. So keep important pages no more than three clicks from the homepage — deep pages are crawled less frequently and updated more slowly. Maintenance matters just as much: broken links, meaning 404s that lead nowhere, waste crawl budget and damage user trust. Check your site regularly with a crawler and fix or redirect broken references before they pile up.

Backlinks: quality beats quantity

Backlinks from credible, topically relevant domains remain a strong ranking signal — but the equation reads quality over quantity. A single link from a relevant expert source outweighs a hundred from link farms, and bought bulk links are more risk than lever today. Focus on earning links: through content others cite voluntarily. The disavow tool is the rare exception here, not a routine cleaning product — use it only when you have evidence of a manual action or a clearly toxic link pattern. Blanket disavowing harms more often than it helps.

FAQ

Are backlinks still important in 2026?

Yes, but differently than before. They remain a strong trust signal, but what counts is the quality and topical proximity of the referring source, not sheer volume. A few links from credible, relevant pages do more than large quantities from arbitrary directories.

Should I disavow harmful links?

Only with evidence. The disavow tool is meant for demonstrably toxic patterns or a manual action, not for precautionary tidying. Google ignores most low-quality links on its own anyway. Blanket disavowing can devalue good links too and do more harm than good.

How many internal links per page make sense?

There is no fixed number — relevance decides. Link as many related pages as fit the text meaningfully, with descriptive anchors. What matters is that every important page stays internally reachable at all and is not buried too deep.
