I Analyzed 300K Keywords. Here's What I Learned About AI Overviews

Google AI Overviews aren't optional territory anymore. They're sitting at the top of search results, answering questions before users even scroll, and reshaping how traffic flows across the web.

So I decided to actually look at the data.

Over the past few months, I tracked over 300,000 keywords across multiple industries to understand exactly when Google AI Overviews appear, what content gets cited, and what that means for your SEO strategy in 2026. The results surprised me in a few places. Let me walk you through what I found.

Before we get into the findings, you need to know what you're looking at.

The Data Set

The 300,000 keywords I tracked came from a mix of industries: SaaS, e-commerce, health, finance, legal, and local services. I pulled queries ranging from short-tail navigational terms all the way down to long-tail informational ones.

Each keyword was checked for:

• Whether a Google AI Overview appeared in the results
• Which domains got cited inside the AI Overview
• The intent type of the query
• The search volume bracket
• The page structure of cited content

How I Tracked AI Overview Appearances

Tracking AI Overviews manually at scale isn't realistic. I used a combination of automated SERP crawls and AI visibility tracking tools, including Semly Pro's AI tracking prompts, to log when and where overviews appeared. The data was collected across a rolling 90-day window in 2026, which means it reflects current behavior, not patterns from a year ago.

That context matters. A lot has changed.

AI Overviews don't appear randomly. There are clear, repeatable patterns once you look at enough data.

Which Query Types Trigger AI Overviews Most

Informational queries dominate. Full stop.

In my data set, AI Overviews appeared on roughly 62% of informational queries. Compare that to transactional queries, where the rate dropped to around 14%. Navigational queries? Almost never.

What does that mean for you? If you're writing "how to" content, comparison guides, definition articles, or anything that answers a direct question, you're playing in AI Overview territory whether you plan for it or not.

The intent breakdown looked like this:

Word Count Doesn't Win It Alone

I expected to find a strong correlation between longer content and AI Overview citations. It's not that simple.

Pages with 1,200 to 2,500 words actually got cited more frequently than pages over 4,000 words. The sweet spot isn't writing more. It's writing the right structure with the right density of direct answers.

Honestly, the wall-of-text approach hurts you here. Google's AI pulls from content that's easy to parse, not content that buries its answers in paragraphs.

Domain Authority Still Matters, But Not How You Think

High-authority domains do get cited more often overall, but here's what surprised me: lower-authority domains with well-structured, specific content were cited at rates that beat mid-authority sites with generic coverage.

Specificity beat authority in about 23% of the competitive queries I tracked. That's not a small number. It tells you that a sharp, well-organized answer on a newer site can absolutely earn a spot in AI Overviews.

This is probably the most useful section if you're trying to get your content included.

Content Structure Plays a Huge Role

The single biggest differentiator between cited and non-cited content was structure. Pages that used clear H2 and H3 subheadings, short paragraphs, and direct answers near the top of the page were cited at nearly twice the rate of pages with unbroken text blocks.

What cited pages had in common:

• A clear answer in the first 100 words
• Subheadings that matched question-style phrasing
• Bullet lists or numbered steps for process-based topics
• FAQ sections (yes, these showed up repeatedly in cited content)
• Schema markup, especially FAQ and HowTo schema

Think about it: Google's AI needs to extract a clean answer. Give it one. Don't make it work for it.

Freshness Signals Matter More Than Expected

Pages updated within the last six months were cited significantly more often than older, static pages, even when the older pages had more backlinks. in rapidly changing topics like AI tools, software comparisons, and health guidelines, freshness was nearly as important as authority.

For fast-moving industries, regularly refreshing your top content isn't just good practice. in 2026, it's pretty much required if you want to show up in AI Overviews.

The Zero-Click Problem Is Real

Let's be honest about this part.

AI Overviews do reduce clicks on some queries. in my tracking, queries where an AI Overview appeared saw an average CTR drop of around 18-27% on organic positions 1 through 5. That's not nothing.

For simple factual queries, the user gets their answer and leaves. There's not much you can do about that, but that's not the full story.

But Citations Drive Qualified Traffic

Here's the flip side. Pages that got cited inside the AI Overview saw a measurable traffic increase, even as overall clicks on that SERP dropped. The citation link carries intent. Users who click through from an AI Overview already trust the source Google chose. They're further along in their decision process.

In plain terms: fewer clicks overall, but better clicks to cited pages. If your page earns a citation, you're not competing for scraps. You're getting the most valuable visitors in that SERP.

That's the opportunity worth chasing in 2026.

Knowing AI Overviews matter is one thing. Actually tracking whether your content shows up in them is another challenge entirely.

Semly Pro was built for exactly this. It's the tool I used throughout this analysis, and it's worth breaking down what it actually does.

What Semly Pro Tracks That Others Don't

Most SEO tools still report traditional rankings. Semly Pro tracks AI visibility, which includes:

• Whether your domain gets cited in Google AI Overviews
• Your AI visibility score across tracked keywords
• Competitor citations in the same AI Overview results
• Citation alerts when your mentions change
• LLMs. txt generation to help AI systems understand your site
• Advanced AI metrics across ChatGPT, Perplexity, and Google AI Overviews

No other tool in the market wraps all of that into one dashboard. That's not me being promotional. It's just the gap that exists right now.

How the Plans Break Down

Semly Pro runs on three tiers, all priced in EUR:

• Pro (€139/mo): 40 long-form SEO articles, 25 AI tracking prompts, 1 project, AI visibility score, competitor detection, email support
• Business Pro (€229/mo): 100 articles, 50 AI tracking prompts, 3 projects, advanced AI metrics, LLMs. txt generation, data export, priority support
• Managed SEO (€469/mo): Everything in Business Pro plus a dedicated strategist, weekly AI visibility tracking, citation monitoring managed for you, schema and LLMs. txt optimization, monthly strategy calls

There's a 7-day free trial on the Pro plan. No commitment required. If you want to see where your content actually stands in AI Overviews before you change anything, that's the place to start.

Let's put it in a table. Here's how Semly Pro stacks up against other tools for AI Overview tracking specifically.

Most traditional SEO tools are catching up slowly. As of 2026, Semly Pro is the only option that covers all four pillars: tracking, scoring, LLM optimization, and citation monitoring in a single platform.

Based on everything the data showed me, here's the actual process that moves the needle.

Step-by-Step Process

1. Identify your AI Overview keywords. Use Semly Pro's AI tracking prompts to find which of your target keywords already trigger AI Overviews. Focus your energy there first.
2. Check who's getting cited. Before rewriting anything, look at what's currently getting cited for those queries. Note the structure, length, and format of cited pages.
3. Rewrite your opening paragraph. Put your clearest, most direct answer in the first 100 words. Don't build up to it. Lead with it.
4. Add question-style H2s and H3s. Subheadings that match how people phrase questions are pulled more frequently. "What is X" and "How does X work" outperform generic topic headings.
5. Break content into scannable chunks. Short paragraphs, bullet lists, numbered steps. If your answer can be a list, make it a list.
6. Add or update your FAQ section. FAQ schema + a well-written FAQ section is one of the highest-ROI changes you can make. It appeared in cited content repeatedly in my data.
7. Refresh the page date. Update content regularly. Even small additions and corrections signal freshness, which matters for AI Overview selection.
8. Generate and publish an LLMs. txt file. This tells AI crawlers how to understand your site. Semly Pro's Business Pro and above plans generate this automatically.

What are Google AI Overviews?

Google AI Overviews are AI-generated summaries that appear at the top of some search results pages. They pull information from multiple sources across the web and display a synthesized answer, often with citation links to the original pages.

How often do Google AI Overviews appear?

Based on the 300,000 keywords I tracked in 2026, AI Overviews appear on roughly 62% of informational queries, 31% of commercial investigation queries, and only about 14% of transactional queries. Navigational queries almost never trigger them.

Does ranking #1 guarantee inclusion in AI Overviews?

No. Ranking first in organic results doesn't automatically mean you'll be cited in the AI Overview. Google's AI pulls from pages it considers most accurate and clearly structured for the specific query, which isn't always the top-ranking page.

What content types get cited most in AI Overviews?

Informational articles with clear structure, direct answers near the top of the page, subheadings that match question phrasing, and FAQ sections tend to get cited most frequently. Freshness also plays a notable role.

Do AI Overviews hurt organic traffic?

On some queries, yes. My data showed an average CTR drop of 18-27% on positions 1 through 5 when an AI Overview appeared, but pages that earned a citation inside the AI Overview saw a net traffic increase. It depends entirely on whether you're cited or not.

How can I track if my content appears in Google AI Overviews?

Tools like Semly Pro specifically track AI Overview citations and give you an AI visibility score. Most traditional rank trackers don't track this yet. You can start with Semly Pro's 7-day free trial on the Pro plan at €139/mo to see where you currently stand.

What is LLMs. txt and why does it matter for AI Overviews?

LLMs. txt is a file you publish on your website that tells AI systems how to read and understand your content. It's similar in concept to robots. txt but designed specifically for large language models. Having one can improve how accurately AI tools represent your site, including in AI Overview citations.

Does domain authority still matter for AI Overview citations?

It's a factor, but not the only one. in my analysis, highly specific and well-structured content from lower-authority domains beat mid-authority domains with generic coverage in about 23% of competitive queries. Authority helps, but it doesn't override content quality and structure.

How frequently should I update content to stay in AI Overviews?

For fast-moving topics, every three to six months is a reasonable target. For more stable evergreen content, annual updates may be sufficient. The key signal is whether your content still directly answers the query better than alternatives that have been updated more recently.

What's the best first step to optimizing for Google AI Overviews?

Start by identifying which of your target keywords actually trigger AI Overviews, then check who's currently getting cited for those queries. From there, restructure your content to lead with direct answers and use question-style subheadings. Semly Pro makes the identification step much faster with its AI tracking prompts.
