Is Link Building Still Relevant to SEO in 2026?

Yes, link building is still relevant to SEO in 2026. Google still uses link analysis, including PageRank, in its ranking systems. Earning useful editorial links remains a legitimate part of competing for organic visibility.

That doesn't mean links deserve your next marketing dollar.

For a SaaS company, the real question is whether stronger external references would help a page that already answers a buyer's question, or whether you're trying to promote a page, product, or offer that isn't ready. Those are different investments.

Here's the verdict: keep link building in your strategy, but make it earn its place in this quarter's budget. Neither “links are dead” nor “more links will fix it” is a useful operating rule.

What Google's comments actually mean

The debate didn't come from nowhere. In a November 2022 Search Off the Record Q&A, Google's John Mueller anticipated that the weight placed on links would decline as Google got better at understanding content. He framed that as an expectation, not a published percentage or an announcement that links had stopped counting.

Two later remarks get quoted just as often. In 2023, Gary Illyes said links had not been a top three ranking factor "for some time". In April 2024 he went further at a conference, saying Google needs "very few links to rank pages", then added on X that he shouldn't have said it. Neither comment said links had stopped counting. Both said they count for less than the industry assumed.

Google's current ranking-systems documentation still identifies PageRank as part of its core systems. Its link-analysis systems help it understand what pages are about and which may be useful for a query.

Those positions aren't contradictory. A ranking signal can become less decisive without becoming irrelevant. Don't turn an older “top three factors” claim into a permanent rule, either: the documentation doesn't provide a universal weighting for your query.

The distinction matters when evaluating what link building does for SEO. Its role in discovery and ranking isn't a guarantee that another campaign will outperform fixing a weak comparison page. Relevance is the broad answer. Priority requires evidence about your site.

The evidence supports relevance, not guaranteed returns

There is measurable evidence, but it needs the right label.

In Ahrefs' January 2025 study of one million search results pages, researchers selected the highest-volume US keywords and examined their top 20 results. Referring domains showed a 0.255 Spearman correlation with rankings, alongside 0.248 for backlink count. Both are weak or very weak correlations.

That's an association, not a promised lift. A coefficient of 0.255 doesn't mean links improve rankings by 25.5%, and the study didn't randomly assign backlinks to otherwise identical pages.

Popular brands may attract both links and strong rankings. Pages that already rank can also earn links because more people discover them. The high-volume US sample isn't a precise model for a niche B2B query with limited searches.

Still, the combination matters: link analysis is part of Google's ranking systems, and a large observational sample shows an association between link metrics and rankings. Neither supports declaring backlinks irrelevant. Neither proves that buying a particular number will produce pipeline.

For a marketing team, the value of backlinks needs a page-level business case, not just an industry statistic. Treat the study as a reason to investigate your opportunity, not permission to skip that investigation.

Put the strongest evidence side by side and the pattern is consistent: links still help pages rank, and they help less than they used to with everything that happens after the ranking.

When links aren't the answer

Consider a hypothetical workflow SaaS targeting procurement teams. Its use-case page gets relevant impressions, but the copy never explains approval permissions or integrations. Prospects who reach a demo discover that the product doesn't support their required workflow.

A campaign might increase exposure. It won't create the missing capability or answer the missing question.

The same investment problem appears when an important page is accidentally excluded from indexing or when thin content doesn't match what buyers need. Fixing access or usefulness changes what you're promoting. More links don't perform that repair.

Product-market fit is a separate constraint: repeated wrong-fit demos, poor activation, or rejection of the core offer warrant customer and product work, not an automatic increase in acquisition spend.

Don't confuse “not the bottleneck today” with “never useful.” The decision is about sequencing. Make the page and offer worth discovering, then reconsider distribution.

AI citations change what you measure

AI Overviews make the relevance question more urgent, but they don't supply evidence that backlinks have become obsolete.

A backlink points from another webpage to yours; our primer on how backlinks work covers the mechanics. A brand mention names you. An AI citation identifies a source within an answer. A system may cite a page without recommending its publisher's product, and a brand mention may arrive without a citation or clickable link.

A page must be indexed and eligible for a Search snippet to appear as a supporting link in AI Overviews or AI Mode. Eligibility isn't guaranteed selection, and Google's requirements shouldn't be generalized to every LLM.

The data points two ways at once. Most pages cited in AI Overviews already rank on Google's first page, so the work that earns rankings, links included, still feeds AI visibility. But when you ask which brands appear in those answers, mentions across the web track far more closely than link counts do.

That makes link building in AI search a broader measurement problem, not a reason to rename every mention a backlink. Track links, mentions, citations, and qualified visits separately. Mentions you already have are the cheapest place to start: turning unlinked brand mentions into links serves both lines at once.

Digital PR can create material worth referencing, such as original research or expert explanations. But a recognizable brand entity isn't a purchasable citation guarantee. Nor is E-E-A-T a numerical score you increase by adding links.

The bar rises for the campaign's usefulness: can it produce a credible source that someone would actually reference? Don't fund a link-count target and assume AI visibility will follow.

Four signals to check before investing this quarter

Use these as a decision sequence, not four reasons to approve a campaign regardless of what you find.

1. A specific page has a credible commercial job

Name the URL, the buyer it serves, and the next useful action. An integration page helping an operations lead evaluate compatibility has a clearer job than an article chasing loosely related traffic.

Check this week: Review the page with sales or product marketing. Inspect search-query relevance, demo feedback, and conversion paths. New pages won't have much data, so use customer interviews rather than pretending absence of data proves demand.

Decision: Fund promotion when there's credible buyer fit and a useful destination. If the offer or audience remains uncertain, validate that first. Good SaaS link building needs somewhere commercially relevant to send attention, even when the immediate landing page is educational.

2. The suspected link gap survives a fair comparison

Compare pages serving the same intent, not your startup's domain against a giant software brand. Look at the relevant editorial referring domains behind those pages, while checking differences in usefulness and page type.

Check this week: Inspect a small set of comparable pages and the sources linking to them. Ask whether those sources reference evidence, a tool, expertise, or something your page genuinely lacks. Our guide to sizing the link gap for a single query walks through that comparison step by step.

Decision: A credible reference gap makes links a hypothesis worth testing, not a proven cause of the ranking gap. If the comparison exposes a better answer or better intent match, improve yours first. Third-party domain authority is a comparison metric, not Google's own score or a spending target. It is the same competitor gap analysis we run before any SaaS link building engagement starts.

3. You have a defensible reason to earn attention

“We need links” isn't a publisher's reason to reference you. Useful benchmark data, a genuinely helpful calculator, or a specialist explanation gives an editor something to work with.

Check this week: Write down the asset, the audience, and why a relevant publisher would cite it. Identify plausible publications and let someone outside the campaign challenge the pitch. If you need ideas, these backlink tactics built on assets only a SaaS product has are a good shortlist.

Decision: Proceed when the work has value beyond placing a URL. If the only plan is guaranteed ranking credit from interchangeable placements, stop and rethink it. Budget for research, production, outreach, and review; comparing link building pricing without those inputs can make an apparently cheap option misleading.

4. You can learn whether the investment helped

An increasing link count doesn't settle the budget question. You need a baseline and a decision rule before launch.

Check this week: Record target-page visibility, relevant visits, qualified conversions, campaign costs, and concurrent site changes. Choose a review window that fits your crawl activity and sales cycle, not a promised universal payback date. The SEO KPIs that tie search to pipeline give you a ready-made baseline.

Decision: Run a bounded test with an owner and a spending limit. Review placement quality alongside business signals. If results disappoint, inspect the page, audience, placements, and tracking before simply scaling volume.

Link building ROI remains uncertain when several changes happen together. Separate observed outcomes from the share you can reasonably attribute to the campaign.

The verdict for 2026

Backlinks still matter. Automatic budget approval doesn't follow. Links still help pages rank, ranking still feeds AI answers, and mentions now carry weight that link counts alone don't capture.

If you can name a useful page, a plausible reference gap, a worthwhile asset, and a way to evaluate results, link building deserves a considered test. If you can't, the better decision may be to fix something else first.

That's not abandoning the tactic. It's refusing to let a general truth replace a specific investment decision.
