Google AI Overviews Surge to More Than 80% of Branded Searches in September 2026

Google’s AI Overviews saw a dramatic increase across branded search queries in late September 2026, raising new questions about how brands will attract organic traffic as AI-generated answers become more common in Google Search.

New data from DemandSphere indicates that AI Overviews appeared on more than 80% of tracked branded queries by the end of September. The figure represents a major increase from approximately 26% at the beginning of the month.

The sharpest growth occurred during the final days of September, when AI Overview visibility suddenly accelerated across branded searches.

AI Overview Visibility Rose Rapidly in Late September

DemandSphere’s tracking data shows that AI Overviews appeared on roughly 27% to 35% of branded queries for much of September.

That pattern changed significantly during the final week of the month.

AI Overview presence climbed to 69.21% on September 26 before reaching a September peak of 90.48% on September 27.

Visibility remained elevated afterward, reaching:

• 80.23% on September 28
• 82.06% on September 29

The data suggests that Google significantly expanded the circumstances in which AI-generated summaries appear for searches involving brands.

However, Google has not publicly announced a specific Search update explaining the sudden increase.

More Brands Are Appearing Inside AI Overviews

The expansion is not limited to a small group of major companies.

Chris Long, co-founder of Nectiv, separately tested 100 enterprise brands using SerpApi. His test found AI Overviews appearing for 93 of the 100 brands examined.

The brands observed in the test included well-known companies such as Reddit, Salesforce, Mailchimp and Facebook, along with smaller businesses.

This suggests that AI Overviews are increasingly becoming part of the branded search experience across different types of companies rather than being restricted to only the largest brands.

Why Branded Searches Matter for SEO

Branded searches have traditionally been among the most valuable organic search queries for businesses.

When someone searches for a company by name, they may be looking for:

• Company information
• Products or services
• Customer reviews
• Pricing
• Competitors
• Contact information
• Product comparisons
• Reputation-related information
• Official websites and resources

If Google places an AI Overview above traditional search results for these queries, users may receive much of the information they need without immediately clicking through to the company’s website.

That makes visibility inside the AI-generated answer increasingly important.

AI Overviews Could Change Brand Visibility

Traditional SEO focuses heavily on rankings, impressions and clicks.

AI-powered search introduces another layer: whether a brand is represented accurately and prominently inside Google’s generated answers.

For businesses, this means monitoring more than just where their website ranks.

Brands may increasingly need to understand:

1. Which branded searches trigger AI Overviews.
2. What information Google presents about the brand.
3. Which websites are cited as sources.
4. Whether the official website appears in the citations.
5. Whether competitors are mentioned in the same AI-generated answer.
6. How frequently the brand is represented across different queries.

This could make AI search visibility an important extension of traditional brand SEO.

The Impact on Click-Through Rates Is Still Unclear

The rapid growth of AI Overviews naturally raises concerns about organic click-through rates.

If users receive a detailed answer directly within Google Search, some may have less reason to visit individual websites.

However, the available DemandSphere and SerpApi data does not establish how much branded search traffic is being lost.

The datasets measure the presence of AI Overviews, not the number of clicks generated or lost.

Therefore, it would be premature to conclude that the increase has already caused a specific decline in branded organic traffic.

The real impact will become clearer as more click, impression and conversion data becomes available.

What the DemandSphere Data Shows

DemandSphere tracked branded keywords through its DemandMetrics platform, checking queries once per day across markets and devices.

An AI Overview was counted whenever one appeared for a query, regardless of whether Google’s generated answer directly cited the brand being searched.

This distinction is important because the presence of an AI Overview does not necessarily mean that the searched brand is featured prominently within the generated response.

What SEO Teams Should Do Now

The growing presence of AI Overviews means businesses should begin treating AI search visibility as part of their broader SEO strategy.

Monitor Branded Queries

Create a list of important branded searches and regularly check whether AI Overviews appear for them.

These can include searches involving:

• Brand names
• Brand + product
• Brand + pricing
• Brand + reviews
• Brand + alternatives
• Brand + competitors
• Brand + locations

Track AI Overview Sources

Pay attention to which websites Google cites when generating answers about your brand.

If third-party websites repeatedly appear while your own site is absent, that may indicate an opportunity to strengthen your brand’s authority and supporting content.

Strengthen Brand-Focused Content

Businesses should maintain clear, trustworthy information about their products, services, company background and areas of expertise.

Accurate and comprehensive content can help search engines better understand what a brand offers and how different pages relate to the business.

Continue Investing in Traditional SEO

AI Overviews do not eliminate the importance of organic search.

Technical SEO, helpful content, authoritative links, strong brand signals and a well-structured website remain important components of search visibility.

Instead, businesses now need to think about both traditional rankings and AI-generated search experiences.

Google’s AI Search Evolution Is Accelerating

The late-September increase in branded AI Overviews highlights how quickly Google’s search experience can change.

A jump from approximately 26% to more than 80% of tracked branded queries within the same month represents a substantial shift in search-result behavior.

Although Google has not confirmed the reason for the increase, the data indicates that AI-generated answers are becoming increasingly visible even when users search specifically for established brands.

For SEO professionals and businesses, the takeaway is straightforward: ranking on Google may no longer be the only visibility metric that matters.

Understanding how a brand appears in AI Overviews, what information Google uses, and which sources receive citations could become increasingly important as AI-powered search continues to evolve.
