What impacts SEO the most?

Key Facts

If your traffic feels like it's slipping even though you haven't changed anything, you're not imagining it. Search itself has changed — and the numbers behind that change are stark.

According to recent search behavior data, 58.5% of Google searches now end without a single click. Meanwhile, Ahrefs' research shows that 96.55% of all pages get zero traffic from Google. And Google AI Overviews now appear on up to 52% of tracked searches, answering questions directly on the results page before a user ever reaches a website.

The impact on traditional rankings is measurable. A large-scale ranking factors study found that AI Overviews cut the click-through rate of the #1 organic result by 15–60%, with informational queries hit hardest and local queries least affected. When Google can summarize the answer, fewer people scroll — and fewer click.

Here's the important part: AI Overviews are not killing SEO. As the ranking study puts it, they're changing which queries are valuable to target. The searches that used to send visitors to a "what is" blog post now get answered instantly. But the searches where people need a real business — an emergency plumber, a local attorney, a reliable accountant — still route through Google, Maps, and increasingly AI assistants.

What's actually happening is a redistribution of visibility:

  • Simple informational queries are being absorbed by AI-generated answers
  • Local and service-based queries remain the least affected by AI Overviews
  • Brand mentions and authority signals now influence whether AI systems cite you at all

This is the point most businesses miss. AI SEO is an extension of traditional SEO, not a substitute. As Semrush explains, traditional SEO improves visibility in search results pages, while AI SEO improves visibility in AI-generated answers from tools like ChatGPT, Gemini, and Google AI Overviews. The same foundations power both.

That's why AI systems value the "evidence layer" around your business: local SEO, useful content, technical accessibility, reviews, citations, and clear business facts. AI tools even value unlinked brand mentions across the web — Semrush documented Google's AI Mode recommending a brand cited in a news article without any link to its website.

At AI SEO Consultants, we approach this the same way: build the evidence layer first, then make it easy for AI systems — and traditional search — to find, trust, and reuse it. The rules have shifted, but the fundamentals still decide who wins. The rest of this article breaks down exactly which factors matter most.

The pages that win in search today don't win because they're long or loud — they win because they're genuinely more useful. A ranking factors study found that content information gain is the strongest on-page predictor: pages ranking #1 score 3.2× higher on information gain than position-10 pages, while word count alone shows only a 1.1× correlation. Writing 3,000 words about a topic that 50 other articles already cover will not move rankings; adding a new angle, a fresh data point, or a better answer will.

First-hand experience is the biggest content differentiator. Pages with original data, case studies, or documented experience rank 2.4× higher than generic content, and AI-generated summaries scored lowest on experience signals. This matters even more as AI Overviews and answer engines pull from the web: they favor content that demonstrates real-world knowledge, not just keyword coverage. AI systems also extract content in chunks and combine it with other sources, so each section needs to make sense standalone, as Semrush's research on AI SEO notes.

Backlinks still matter, but the math has changed. Ten topically relevant backlinks outperform 1,000 irrelevant ones, and topical relevance is 4× more predictive than raw domain rating. Links from pages already ranking for related keywords carry 2.7× more weight. One relevant link from a respected industry publication is worth more than a pile of unrelated directory links.

E-E-A-T — Experience, Expertise, Authoritativeness, Trustworthiness — is not a direct ranking factor or a checklist to tick off. According to SEO research, it's a framework for assessing content quality that informs how quality raters evaluate pages and how algorithms learn. The practical takeaway:

  • Publish original research, case studies, or documented experience instead of rehashing what competitors already wrote
  • Earn links from pages that already rank for related topics, not from low-relevance directories
  • Structure content in self-contained sections that AI systems can extract and cite
  • Keep business facts consistent across your website, Google Business Profile, and citations

These factors form the evidence layer that both Google and AI answer engines use to decide who to recommend. At AI SEO Consultants, we help businesses build that layer — useful content, technical accessibility, consistent local signals, and genuine authority — so they become the business AI recommends.

Technical SEO and Local Signals: The Gatekeepers Most Businesses Fail

Most websites lose rankings before content quality even enters the equation. Technical failures and weak local signals quietly disqualify otherwise strong pages — and the data shows exactly where businesses are falling short.

Core Web Vitals act as a hard gatekeeper, not a tiebreaker. According to ranking factors research, pages passing all three metrics are 1.8× more likely to rank in the top three positions. Yet Ahrefs data shows only 33% of websites pass Core Web Vitals, and 72.3% of sites have slow pages. That means two-thirds of the web is fighting an uphill battle before a single word of content is evaluated.

A newer, equally dangerous gatekeeper is AI crawler accessibility. Semrush's analysis of AI search found that most major AI crawlers do not render JavaScript — meaning JavaScript-heavy sites may be effectively invisible to the systems generating answers in ChatGPT, Perplexity, and Google AI Overviews. Blocking AI crawlers in robots.txt compounds the problem, preventing AI visibility entirely.

Local businesses face a parallel set of gatekeepers. Google Business Profile signals now account for 32% of local pack weight, making GBP the single most important local asset. And within local ranking factors, three signals stand out from the same study:

  • Review velocity beats volume — 4+ new reviews per month correlates with 34% higher local pack rankings
  • Entity consistency at 95%+ drives 2.1× higher local rankings, and consistency explains 47% of local ranking variance
  • Businesses posting to GBP weekly rank 2.3× higher than monthly-or-less posters

The lesson is blunt: as one analysis put it, citation building is dead — citation consistency is what matters. A plumber with 200 reviews from two years ago will lose to a competitor earning six fresh reviews a month with matching NAP data across every directory.

This is why AI SEO Consultants treats technical accessibility and local signals as the evidence layer AI systems discover and reuse — not as separate workstreams. A technically sound, locally consistent business is discoverable by both traditional algorithms and AI answer engines. Fix the gatekeepers first, and every content investment afterward performs better.

How to Win in Both Google and AI Answers: Your Action Plan

Winning in Google and AI answers isn't about chasing two separate algorithms — it's about building one strong evidence layer that both systems can discover, trust, and reuse. Here's how to put that into practice.

Structure content for AI extraction. AI systems pull content chunks and combine them with other sources, so every section must make sense on its own. Write direct, clear copy with a logical heading hierarchy. According to research on AI citation patterns, content built with 40-60 word paragraphs and structured headings improves citation rates.

Target topic areas, not single keywords. Conversational prompts and AI "query fan-out" mean prompt targeting is broader than keyword targeting. Map entire topic areas — the questions customers actually ask — rather than obsessing over one head term.

Build brand mentions and authority. Brand search volume has the strongest correlation with AI citations — stronger than backlinks. Even unlinked mentions carry weight: Google's AI Mode once recommended Nudie Jeans based on a Guardian article that never linked to the brand's site. Get mentioned where your customers read.

Handle the technical and local fundamentals:

  • Add structured data — it helps Google understand context and improves AI Overview inclusion chances (Single Grain's research).
  • Don't block AI crawlers in robots.txt, and know that most major AI crawlers don't render JavaScript.
  • Post to your Google Business Profile weekly — weekly posters rank 2.3× higher than monthly-or-less posters.
  • Keep review velocity up: 4+ new reviews per month correlates with 34% higher local pack rankings.
  • Maintain 95%+ entity consistency across listings, which drives 2.1× higher local rankings.

Think of all of this as the evidence layer AI systems discover and reuse: local SEO, useful content, technical accessibility, reviews, citations, and clear business facts. AI answers don't replace conventional SEO — they reward the businesses that did it well all along.

If you'd rather not manage dashboards and robots.txt files yourself, AI SEO Consultants handles this full stack — from GBP optimization to AI crawler accessibility — with clear, month-to-month reporting you own.

Results are directional, not guaranteed — but the businesses building this layer now are the ones AI answers cite tomorrow.

Where to Start: Getting a Clear Picture of Your Visibility

To maximize visibility in search engines, it's essential to understand the primary factors that impact SEO performance. According to industry research, both traditional SEO and AI SEO are crucial for businesses to succeed online.

A recent study found that content information gain is the strongest on-page predictor, with pages ranking #1 scoring 3.2× higher on information gain metrics than position-10 pages. Additionally, SEO statistics show that 96.6% of all Google search clicks go to first-page results, highlighting the importance of strong SEO foundations.

To get a clear picture of your visibility, it's vital to assess your current SEO performance. This includes evaluating your website's technical accessibility, content quality, and local signals. A key aspect of this is ensuring your Google Business Profile is complete and accurate, as research shows that review velocity is more important than review volume, with 4+ new reviews per month correlating with 34% higher local pack rankings.

Some essential steps to improve your SEO visibility include:

  • Building a strong evidence layer of local SEO, useful content, technical accessibility, reviews, citations, authority, and clear business facts
  • Optimizing for AI extraction by using clear, direct writing and self-contained sections
  • Focusing on content quality and E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) to improve your chances of AI Overview inclusion

By following these steps and prioritizing content quality and technical SEO, businesses can enhance their online visibility and stay ahead of the competition.

However, managing dashboards and tools to track and improve SEO performance can be time-consuming and overwhelming, especially for small local businesses and professional firms. That's why AI SEO Consultants offers a free AI SEO Visibility Report, providing a directional starting point to see where your business stands in Google, Maps, and AI answer engines. This report feeds into a done-for-you, month-to-month managed service, where you own everything, and receive clear reporting on your SEO performance.

Frequently Asked Questions

Is AI killing SEO, or should I still invest in it?
AI Overviews aren't killing SEO — they're changing which queries are worth targeting. Simple informational searches get answered instantly by AI, but AI Overviews cut the #1 organic result's click-through rate by 15–60%, while local and service-based queries remain the least affected. The fundamentals (content quality, links, local signals) still decide who wins.
What's the single biggest ranking factor I should focus on?
Content information gain is the strongest on-page predictor: pages ranking #1 score 3.2× higher on information gain than position-10 pages, while word count alone shows only a 1.1× correlation. That means adding a new angle, fresh data, or a better answer beats writing another 3,000-word rehash of what competitors already published.
Do backlinks still matter, or has AI search made them obsolete?
Backlinks still matter, but relevance now beats volume. Ten topically relevant backlinks outperform 1,000 irrelevant ones, and topical relevance is 4× more predictive than raw domain rating. For AI citations specifically, brand search volume has an even stronger correlation than backlinks.
How do I get my business cited in AI answers like ChatGPT and Google AI Overviews?
Build what AI systems can discover, trust, and reuse: clear business facts, useful content, reviews, and consistent local signals. Even unlinked brand mentions carry weight — Google's AI Mode once recommended a brand cited in a news article that never linked to its website. Structuring content in self-contained sections with clear headings also improves citation rates.
My website relies heavily on JavaScript — does that hurt my AI visibility?
Yes, it can. Most major AI crawlers don't render JavaScript, so JavaScript-heavy sites may be effectively invisible to the systems generating answers in ChatGPT, Perplexity, and Google AI Overviews. Also check that you're not blocking AI crawlers in robots.txt, which prevents AI visibility entirely.
For a local business, what actually moves the needle in Google Maps and the local pack?
Google Business Profile signals now account for 32% of local pack weight, making GBP your most important local asset. Review velocity beats volume — 4+ new reviews per month correlates with 34% higher local pack rankings — and weekly GBP posters rank 2.3× higher than infrequent posters. Keep your business name, address, and phone consistent everywhere; 95%+ consistency drives 2.1× higher local rankings.

The Evidence Layer Is the New Playing Field

The answer to what impacts SEO the most isn't a single factor — it's the compounding effect of content with real information gain, technical accessibility, consistent local signals, and genuine brand authority. AI Overviews are reshaping which queries send traffic, but they reward the same fundamentals that always worked: useful, experience-backed content that both Google and AI answer engines can discover, trust, and cite. The businesses losing visibility aren't the ones hit hardest by AI — they're the ones whose evidence layer was thin to begin with. Your next steps are straightforward: audit your Core Web Vitals and AI crawler access, refresh your Google Business Profile activity and review velocity, and restructure key pages so each section stands on its own. If you'd rather have someone handle that full stack for you, AI SEO Consultants offers a free AI SEO Visibility Report showing where you stand in Google, Maps, and AI answers — directional, not guaranteed, but a clear starting point. Research shows pages passing all technical gates are 1.8× more likely to rank top-3 — so start with the gatekeepers. Be the business AI recommends.
