TL;DR
- Backlinks still count as a Google ranking factor, but Google’s own John Mueller and Gary Illyes have said publicly that Google needs “very few links” to rank a page and that links get overestimated (Search Engine Journal, April 2024; Search Engine Land, September 2023).
- Backlinks are a weak predictor of AI citation. Ahrefs’ study of 75,000 brands (May 2025) found brand web mentions correlate with AI Overview visibility far more strongly (r = 0.664) than the raw number of backlinks does (r = 0.218).
- The overlap between AI Overview citations and traditional top-10 rankings has been shrinking fast: from roughly 75% in late 2024, to 54% in October 2025, to as low as 17-38% by early 2026, depending on the study (Search Engine Journal, March 2026, reporting on BrightEdge, February 2026 and Ahrefs, March 2026).
- SparkToro’s June 2026 analysis of Similarweb clickstream data found 68.01% of Google searches in Q1 2026 ended without a click, up from 60.45% in 2024, meaning even a strong backlink profile increasingly can’t guarantee a visitor.
- A March-to-August 2026 survey of 500 SEO professionals (ReporterOutreach, “State of Link Building 2026”) found 74% believe backlinks affect AI search visibility, but only 19% have actually changed their link-building approach for AI search, and just 24% track AI visibility metrics at all.
- I couldn’t find any public technical documentation from OpenAI, Perplexity, or Anthropic confirming their crawlers compute anything like Google’s link-based PageRank, so claims about backlinks directly influencing AI-answer authority should be treated as unproven, not settled.
- My take: backlinks are still worth building in 2026, but as a brand-visibility and trust signal, not as the primary lever for AI citation. Track brand mentions alongside links, not instead of them.

Do Backlinks Still Count as a Google Ranking Factor in 2026?
Yes, backlinks still count as a Google ranking factor, but Google itself says they matter less than most site owners assume. Gary Illyes, from Google’s Search Relations team, told Pubcon Pro Austin attendees, “I think they are important, but I think people overestimate the importance of links. I don’t agree it’s in the top three” (Search Engine Land, September 2023). Seven months later, at a search conference in Bulgaria, he went further: “We need very few links to rank pages… Over the years we’ve made links less important” (reported by Patrick Stox, confirmed by Illyes, April 2024).
John Mueller made a similar point around the same time: “There are more important things for websites nowadays, and over-focusing on links will often result in you wasting your time doing things that don’t make your website better overall” (April 2024). I haven’t found a newer, on-record Google statement from 2025 or 2026 that reverses this position. Most 2026 articles on the topic, including from Backlinko and other SEO publishers, still cite these same 2023-2024 quotes rather than anything more recent, which itself tells you Google’s position hasn’t shifted since.
Do Backlinks Influence Whether AI Search Engines Cite Your Content?
Backlinks have a real but weak correlation with AI citation, and other signals matter more. Ahrefs studied 75,000 brands (published May 2025) and measured how strongly different signals correlated with a brand’s visibility in Google AI Overviews:
| Signal | Correlation with AI Overview Visibility (Spearman r) |
|---|---|
| Brand web mentions | 0.664 |
| Brand anchor text | 0.527 |
| Brand search volume | 0.392 |
| Domain Rating | 0.326 |
| Number of referring domains | 0.295 |
| Number of backlinks | 0.218 |
Backlinks and referring domains are two distinct metrics in this study, and neither is the strongest signal, which connects directly to what I cover in my guide to tracking whether your content is being cited by AI platforms. Both still show a positive correlation, so links aren’t irrelevant to AI visibility, but raw backlink count is roughly three times weaker than brand mentions. Ahrefs published a follow-up study in December 2025 covering AI Overviews, AI Mode, and ChatGPT together, where YouTube mentions emerged as the single strongest signal measured (r of approximately 0.737), stronger even than brand web mentions. That follow-up described backlinks and URL Rating only as “weak” without publishing a precise updated figure for them. I haven’t found an equivalent named study from SEMrush, Backlinko, or SE Ranking that independently correlates backlinks with AI citations; every other source discussing this points back to the same two Ahrefs studies, so treat this as one research team’s data, not a broader consensus.
How Do AI Crawlers Like GPTBot and PerplexityBot Actually Use Links?
AI crawlers don’t appear to compute link-based authority the way Googlebot does, but this is genuinely under-documented territory. Google has clarified that Google-Extended, the crawler token that controls whether content trains Gemini and other Google AI products, is a separate system from Googlebot and explicitly does not affect Google Search ranking (Search Engine Journal, “Google Clarifies the ‘Google-Extended’ Crawler Documentation”). That confirms Google keeps its AI-training crawler and its link-following ranking crawler separate.
For GPTBot, PerplexityBot, and ClaudeBot specifically, I could not find primary technical documentation from OpenAI, Perplexity, or Anthropic describing whether they weight links, follow them for authority scoring, or use them at all beyond basic content discovery. What’s publicly documented from these companies covers robots.txt access and content ingestion for training or retrieval, not anything resembling PageRank. If you see a confident claim online that “AI crawlers use backlinks just like Google,” treat it skeptically. It isn’t backed by anything I could verify, and the honest answer right now is that this mechanism is undocumented, not confirmed either way.
Is Backlink-Driven Referral Traffic Still Worth It With Zero-Click Search Rising?
Referral traffic from any single channel, including backlinks, is worth less today because a growing share of searches never produce a click at all. SparkToro’s June 2026 analysis of Similarweb clickstream data found 68.01% of Google searches in the first four months of 2026 ended without a click, up from 60.45% in 2024. At the same time, Similarweb reports AI chat platforms like ChatGPT, Gemini, and Claude now drive roughly 9.5 billion visits per month in 2026, up 70% year-over-year, while traditional search traffic growth has been flat.
Even when your content does get used as an AI answer source, 5WPR’s 2026 research on AI citation behavior found ChatGPT mentions brands roughly 3.2 times more often than it actually cites them with a link, meaning the click-through opportunity from being mentioned is rare to begin with. I couldn’t find a study that isolates “traffic caused specifically by backlinks” as its own percentage against organic or AI traffic. What’s verifiable is the broader trend: fewer clicks overall, and backlinks alone were never guaranteed to produce direct referral traffic in the first place, since most of their value has always been indirect (helping a page rank, not sending clicks themselves).
Do Backlinks Still Feed Into AI Citations Indirectly, Through Rankings?
This depends on whether the page an AI system cites still needs to rank well organically first, and that connection is getting weaker every few months. Three separate 2026 measurements show the overlap between AI Overview citations and traditional top-10 rankings shrinking:
- Late 2024: roughly 75% of AI Overview citations also appeared in the top 10 organic results (cited in Search Engine Journal’s March 2026 trend coverage).
- October 2025: that overlap dropped to 54% (same source).
- Early 2026: Ahrefs measured 38% overlap in March 2026, while BrightEdge measured a lower 17% in February 2026, using a different methodology.
Whichever exact number you trust, the direction is consistent across every source: AI citation is decoupling from classic organic rank over time. A backlink-driven ranking strategy that used to indirectly guarantee AI visibility is becoming a less reliable bet than it was even a year ago.
What Does Real Link Building Actually Look Like Right Now?
Real link building in 2026 still happens, and it still produces measurable results, but the goal has shifted from “rank higher” to “get mentioned in places that build trust and visibility.” I’ve done this work for two real clients recently through my link building and digital PR services: guest post link building for Doctors Faculty (2025) and location-based link building for Prime Grill Sweden (2024). Neither engagement was built around chasing a specific ranking position; both were about building a genuine, relevant presence across sites that real audiences already trust, which is exactly the kind of signal (brand mentions, real citations, real audience overlap) that correlates more strongly with AI visibility than a raw backlink count does.
On a larger scale, Digitaloft’s published case study on UK outdoor retailer Millets reports over 150 high-authority links earned in 2024 through a sustained digital PR campaign (Digitaloft, “Digital PR & Link Building Statistics 2026”). I don’t have access to that campaign’s detailed traffic or AI-citation figures, so I’m citing only the confirmed link count and year rather than any performance number I can’t verify.
So Should You Still Invest in Link Building in 2026?
Yes, but treat it as a brand-visibility investment first and a ranking tactic second. Most of the industry agrees links still matter for AI visibility but hasn’t actually changed how it works yet: a survey of 500 SEO professionals (ReporterOutreach, “State of Link Building 2026,” fielded Q1 2026) found 74% believe backlinks affect AI search visibility, yet only 19% have changed their link-building approach for AI search and just 24% track AI visibility metrics at all, even though 58% increased their link-building budget year over year. That gap between belief and practice is exactly why I’d rather show you what the data says than repeat what most of the industry still assumes. Here’s how I’d prioritize link building for a business deciding where to spend a limited SEO budget in 2026:
| Priority | Why It Matters More Now |
|---|---|
| Digital PR and genuine media mentions | Brand mentions correlate more strongly with AI Overview visibility (r = 0.664) than backlinks do (r = 0.218), per Ahrefs’ 2025 study |
| Guest content on relevant, trusted sites | Builds both a link and a real mention in a context AI systems and readers both trust |
| Location and industry-specific links | Still supports traditional rankings, which remain relevant even as AI citation decouples from them |
| Chasing raw backlink volume from low-relevance sites | Weakest and most outdated approach; Google has said explicitly it needs “very few links” to rank a page |
Backlinks haven’t stopped mattering, but they’ve stopped being the single lever worth pulling hardest. The businesses I see gaining the most visibility in 2026 are the ones building a genuine presence across the web: mentions, citations, guest content, and reviews, alongside a healthy link count rather than instead of one.

Frequently Asked Questions
Do backlinks still matter for SEO in 2026?
Yes, backlinks are still a confirmed Google ranking factor, but Google’s own Gary Illyes and John Mueller have said publicly that links are overestimated and that Google needs “very few links” to rank a page (2023-2024 statements, still Google’s most recent public position as of 2026).
Do backlinks help you get cited by ChatGPT or Google AI Overviews?
Backlinks show only a weak correlation with AI citation. Ahrefs’ 2025 study of 75,000 brands found the number of backlinks correlates with AI Overview visibility at r = 0.218, compared to r = 0.664 for brand web mentions, meaning brand visibility matters roughly three times more than raw backlink count.
Do AI crawlers like GPTBot and PerplexityBot use backlinks the way Google does?
This isn’t publicly documented by OpenAI, Perplexity, or Anthropic, so it can’t be confirmed either way. What is confirmed is that Google’s own AI-training crawler, Google-Extended, is separate from Googlebot and doesn’t affect Google Search rankings.
Is link-building referral traffic still worth pursuing?
Referral traffic from any single channel is worth less now that 68.01% of Google searches end without a click (SparkToro, June 2026), and ChatGPT mentions brands roughly 3.2 times more often than it links to them as a citation (5WPR, 2026). Link building’s main value today is brand visibility and ranking support, not direct referral clicks.
Why is AI citation becoming disconnected from organic rankings?
The overlap between AI Overview citations and top-10 organic rankings has fallen from about 75% in late 2024 to as low as 17-38% by early 2026, according to Search Engine Journal, Ahrefs, and BrightEdge. This means ranking well organically is no longer a reliable guarantee of being cited by AI systems.
What should businesses prioritize instead of just building backlinks?
Prioritize digital PR and genuine media mentions, guest content on relevant and trusted sites, and location or industry-specific links, since brand mentions and real citations now correlate more strongly with AI visibility than backlink volume alone.
