Backlinks still underpin the Search systems behind AI Overviews — Semrush found a 0.65 correlation between authority and AI mentions. Here's what the research says and which links are worth building.
Yes — link building still supports your visibility in Google AI Overviews. Quality backlinks underpin the core Search systems Google's AI features rely on. No backlink guarantees an AI citation, but building genuine website authority remains a sensible investment.
The bigger question isn't whether links matter — it's which links are worth building and how they support your wider search visibility.
Yes, link building can help your visibility in Google AI Overviews, and businesses shouldn't abandon it just because search is becoming AI-driven.
Quality backlinks remain an important part of traditional SEO, which continues to underpin Google's AI search systems. While no backlink guarantees an AI citation, building genuine website authority is still a sensible investment.
The bigger question isn't whether links matter. It's which links are worth building and how they support your wider search visibility.
Google's official AI search guidance confirms that AI features use its core Search ranking and quality systems.
That matters because links have long helped Google discover pages and evaluate their relevance and importance.
A strong backlink profile can support organic visibility, making your content more discoverable. However, AI Overviews use additional retrieval and citation-selection processes.
Backlinks can improve your foundations, but Google has not confirmed that acquiring more links directly increases AI Overview citations.
Two major SEO studies provide compelling evidence that authority still matters.
| Research | Verified findings |
|---|---|
| Semrush, October 2025 | Studied 1,000 domains and found a 0.65 correlation between Authority Score and AI mentions |
| Ahrefs, March 2026 | Analysed approximately 4 million AI Overview citation URLs across 863,000 keyword results |
| Ahrefs: organic rankings | 37.1% of cited URLs also appeared in the organic top 10 |
| Ahrefs: additional visibility | 36.7% of cited URLs were outside the organic top 100 for the same query |
Sources: Semrush backlink study and Ahrefs AI Overview research.
Semrush's research covered multiple AI search experiences, not solely Google AI Overviews. Its findings demonstrate correlation, not proven causation.
Still, the message for businesses is encouraging: stronger backlink authority is associated with greater AI visibility.
Meanwhile, Ahrefs demonstrates that AI Overviews can cite websites beyond the highest-ranking organic results.
Not all links offer equal value. A relevant editorial mention on a respected industry website is generally a more meaningful opportunity than dozens of unrelated directory listings.
| Link opportunity | Why it's worth considering |
|---|---|
| Relevant industry publications | Topical relevance and qualified audiences |
| Editorial coverage | Brand credibility and referral exposure |
| Expert contributions | Recognition and authoritative citations |
| Contextual links in useful articles | Relevant discovery and referral opportunities |
| Original research coverage | Opportunities to earn further mentions and links |
Our recommendation: Prioritise genuine websites, relevant content, real audiences and editorial quality rather than simply chasing Domain Rating.
Google also requires paid placements intended for advertising or sponsorship to use appropriate link attributes, such as rel="sponsored" or rel="nofollow". Buying links primarily to manipulate rankings violates its spam policies.
Creating excellent content is essential. But publishing it doesn't automatically mean other websites will discover, reference or recommend your business.
That's where a well-managed outreach strategy becomes valuable.
Through professional blogger outreach, businesses can secure relevant content placements while avoiding the time-consuming process of researching publishers, negotiating opportunities and managing publication.
For businesses seeking broader recognition, digital PR campaigns can help secure editorial coverage, expert commentary and brand mentions.
At iNet Ventures, we handle publisher research, manual outreach and placement reporting, helping agencies and brands build a more credible online presence without managing everything in-house.
The objective isn't simply more backlinks. It's to get your business featured in places your audience actually reads and trusts.
Backlinks work best alongside strong SEO fundamentals.
Google's guidance highlights several important areas:
Google also uses query fan-out, exploring related searches when generating AI answers.
This creates opportunities for relevant specialist websites, not just the biggest brands.
Yes, potentially. They support traditional SEO authority, which can indirectly benefit AI visibility. A direct causal effect on citations hasn't been established.
Very likely. Google's current AI search features rely on established Search systems. Although algorithms will evolve, relevant links and credible mentions remain useful beyond any individual search feature.
No. Domain Rating is a third-party metric, not a Google ranking factor. Publisher relevance, editorial quality and genuine audiences matter too.
They may provide indirect benefits. Semrush found similar correlations between AI mentions and follow links (0.334) and nofollow links (0.340), but this doesn't establish equal ranking value.
Absolutely, when done properly. Quality outreach can deliver relevant exposure, referral traffic, brand recognition and opportunities to earn natural links. It shouldn't be treated as a guaranteed ranking shortcut.
No. Google's systems independently select supporting sources, and inclusion cannot be guaranteed.
AI search is changing how customers discover businesses, but authority, credibility and relevance remain important.
Businesses shouldn't choose between link building and AI SEO. They should build a strategy that supports both.
Invest in valuable content, earn relevant editorial coverage and develop a backlink profile built around genuine quality.
If your business needs a stronger online presence, iNet Ventures can help you secure carefully selected outreach and digital PR opportunities, with transparent placement options and no long-term retainer requirement.
