Roughly 58% of consumers now use AI answer engines in their product research each week — and that number is rising fast. As AI-powered answer engines like ChatGPT, Perplexity, and Google AI Overviews become primary discovery surfaces, content and SEO teams are asking the right question: is there a relationship between backlinks and AEO, or is it time to rethink the entire authority playbook?

The short answer is that contextually relevant backlinks carry more value than high-volume, low-relevance links for AEO. But they no longer tell the whole story.

This post breaks down exactly how backlinks and AEO interact, where the differences between AEO and SEO show up in practice, and what a balanced authority strategy looks like right now.

Before diving in, keep in mind that tools like HubSpot AEO are built specifically to help marketing teams track and improve their brand’s visibility across AEO — more on that as we go.

Backlinks and AEO: What Changed and Why It Matters

Traditional search engines use backlinks as a primary authority signal. A link from a trusted domain to your page is, at its core, a vote of confidence — one that gets weighted by the linking domain’s own authority, the relevance of the context, and the anchor text used. Answer engines don’t abandon the traditional logic of off-page SEO. But they layer a great deal more on top of it.

When an AI answer engine like ChatGPT or Google’s AI Overviews assembles a response, it isn’t simply ranking pages by backlink count. It is identifying sources that can reliably ground the answer. Those sources are:

• Current content
• Content that is clearly structured
• Content consistently associated with the right entities and topics

What this means for content and SEO teams is that a high-authority backlink profile is a necessary but no longer sufficient condition for AI visibility. That’s exactly the gap HubSpot AEO was built to close. The tool gives marketing teams a single place to monitor how often their brand appears in AI answers — and what content is driving (or missing from) that visibility.

Backlinks and AEO: Do links still move the needle?

Backlinks still matter for AEO, especially considering SEO is the foundation for any good AI search strategy. However, the type of link matters far more than it once did.
