Google’s AI Overviews (AIOs) have undergone some major changes as of August 2024. The company has introduced a new right-hand link display, saving and language simplifying capabilities in Search Labs, and expanded its AIO feature to six new countries.

The SE Ranking has also been busy. We’ve opened access to our new AI Overviews Tracker, which empowers users to monitor AI Overviews for their keywords, analyze competitors, research sources, and so much more. We’ve also enabled users to detect the AI Overview SERP feature in Keyword and Competitive Research tools. Sign up for our 14-day free trial to learn more about new AI-generated answers through our innovative tools and constant research initiatives. A winning combo for your SEO!

This round of research features plenty more insights—this time about ads. Ads are a crucial part of Google search. They allow new brands to gain visibility if they lack organic traction. We believe it is important to understand the impact AIOs will have on advertising displays and how the two can coexist. This topic becomes even more relevant as Google goes through stormy times navigating an antitrust case and accusations of monopoly power over the online ad market. These events could force Google to sell its advertising business, changing the way ads used to function.

Let’s move on to breaking down the results of our research!

Key Takeaways

12.47% of keywords trigger AI Overviews, which is 5% higher than during our previous research from July 2024.
Niches with the most AIOs include Relationships (46.14%), Food and Beverage (33.46%), and Business (23.40%).
13.51% of the time (1,685 cases), desktop SERPs include both ads and AI Overviews, which is 38.69% less than in June 2024, but 4.04% more than in July 2024.
Niches with the highest ratio of keywords that end up with AIOs and ads simultaneously in SERPs include Pets (68%), Healthcare (65.51%), and Fashion and Beauty (60%).
Niches showing the smallest ratio of keywords triggering both AI Overviews and ads in SERPs include Relationships (3.12%), Career and Jobs (2.38%), and Entertainment and Hobbies (4.88%).
When SERPs contain AI Overviews, text ads are placed at the bottom of the page more commonly than at the top, with 1,170 cases (69.44%) vs 104 cases (6.17%).
When text ads appear at the top of the AIO-inclusive SERP, they are placed below AI-generated snippets more often (55.56%) than above (44.44%).
There is typically one text ad at the top of the SERP, placed both above and below the AIO.
Shopping ads appear below AI Overviews 86.97% of the time and above at a 13.03% rate.
Keywords with a CPC of $0.5 or less trigger AIOs and ads in SERPs more frequently (23.26%). The data is niche-dependent, so the values may differ.
Queries with a search volume of 50 or less lead to a combination of AI Overviews and ads in SERPs more often (29.26%). But this data varies by niche.
Three-word and four-word queries are most likely to trigger both AIOs and ads in SERPs.

Disclaimer:

This research focused on investigating the interplay between Google Ads and Google AI Overviews. We ran automatic data collection for desktop searches and manual analysis of ads and AIO from mobile devices. Our interpretation of the results is our own and we acknowledge that other valid interpretations may exist.

The data we obtained depended on the keywords sampled for this research, queries that triggered AIOs during the study, and other data. The results may vary at different times or under different search conditions.

How have AI Overviews changed during our latest studies?

Let’s start with the basic questions covered in each research iteration. We’ll compare results from our latest data (August 23) with results from July 11 and June 3 based on the 100,013 keywords.

How are AI Overviews appearing in SERPs over time?

Our latest data shows that 12,472 keywords (12.47%) trigger AI-generated responses. Since our previous research, this is a 5% increase in the number of queries that end up with AIOs in SERPs.

87,212 keywords (87.20%) didn’t trigger AIOs, and 328 search queries (0.33%) resulted in a technical error (Google failed to generate an AI response).

Which industries have AI Overviews more frequently?

Our analysis of 20 niches, each represented by around 5,000 keywords, showed that almost all niches triggered more AI Overviews. This is quite natural because this research showed a higher number of AIOs in general.

Here are our main highlights and comparison with previous analysis:

The Relationships niche continues to dominate, rising from 40.64% to 46.14%.
The Food and Beverage niche still maintains a strong second place, increasing from 23.58% to 33.46%.
The Business niche also increased from 18.48% to 23.40%.

Some niches saw significant changes:

The Legal niche had a substantial increase from 0.64% to a whopping 22.30%.
The Cars niche also saw a remarkable rise from 0.24% to 9.65%.
The Real Estate niche, which previously had less than 1% of AIOs, increased 5.40%. This niche still has the least AIOs, but it’s a big jump in just one month.

As for other niches with the least AIOs, the situation is the same (although the numbers are higher this time):

Fashion and Beauty rose from 0.24% to 0.60%.
Ecommerce and Retail increased from 0.28% to 1.00%.
News and Politics grew from 0.68% to 1.28%.
Career and Jobs increased from 0.32% to 1.68%.

Which industries have AI Overviews more frequently

The increased presence of AI Overviews in searches suggests that Google is becoming more capable of generating relevant answers across a broader range of queries. Moreover, almost every niche saw an increase in its percentage of AIOs, which correlates with the increase in AIOs across the board. This means that Google is broadly improving its AI’s response capability across diverse topics.

How do Google Ads and AI Overviews coexist in desktop search?

Google Ads offers a variety of ad formats, each tailored to specific advertising campaigns and goals. Advertisements are labeled as Ads or Sponsored to make it clear that these results are paid. Google distinguishes between several formats but in this research, we focused on two types of ads that appear in Google search and direct users to business websites:

Text Ads: These are traditional ads with a headline, description, and URL. They can appear at the top or bottom of the SERP, or other relevant places.
Shopping Ads: These ads show up in search as a carousel of products. They include product images, prices, and merchant information, to help users compare products quickly before buying.

We investigated how often and where Google Ads appear in search next to Google’s AI Overviews.

Let’s look at what we’ve discovered!

How often do ads accompany AI Overviews?

Our latest dataset included 12,472 cases of AI Overviews appearing in search, with ads accompanying AI-generated responses in 1,685 instances (13.51%). In the 10,787 cases in which SERPs contained AIOs (86.49%), we observed no ads at all.

Note: The data in the table above shows how often ads appeared in search results containing AI Overviews, including instances in which several ad types appeared in a single SERP. We used a different calculation method in previously published studies that’s why that data can differ from the numbers in our current research.

Which niches have the most ads when AI Overviews are present?

When AIOs and ads appeared in search results together (1,685 cases), the following niches had the highest ratio of keywords triggering both AIOs and ads in a single SERP:

Pets: 68% of the niche’s keywords (102 out of 150 queries).
Healthcare: 65.51% of the niche’s keywords (283 out of 432 queries).
Fashion and Beauty: 60% of the niche’s keywords (18 out of 30 queries).

The ratio is based on the total number of keywords that triggered AIOs throughout the niches we analyzed in this research.

Niches with the highest number of keywords leading to both AIOs and Ads in SERPs include:

Healthcare: 283 search queries.
Business: 260 search queries.
Technology: 223 search queries.

Niches like Ecommerce and Retail, Food and Beverage, and Technology tend to include ads without AI Overviews. The combination of AI-generated responses and ads is less common. These niches have the biggest difference in their ratio of keywords triggering SERPs with AIOs and ads vs SERPs without AIOs but with ads: 46.46%, 36.64%, and 22.79%, respectively. The Travel niche is the only one with more keywords triggering ads together with AIOs (2.51%) than keywords triggering ads without AIOs.

Which niches have the most ads when AI Overviews are present

As for instances where we didn’t detect AI Overviews (87,541 cases), the Fashion and Beauty, Pets, and Ecommerce and Retail niches have the highest ratio of keywords triggering ads in search: 83.66%, 80.01%, and 78.46% of keywords, respectively.

Which ad types accompany AI Overviews in desktop searches?

Out of 1,685 instances where ads accompanied AI Overviews, we detected 1,473 (87.42%) in which only one ad type appeared with AIOs:

Text ads appeared at the top of the SERP 104 times (6.17%)
Shopping ads appeared 199 times (11.81%)
Text ads appeared at the bottom of the SERP 1,170 times (69.44%)

Which ad types accompany AI Overviews in desktop searches

Text ads at the top of the SERPs containing AI Overviews

Text ads at the top of the SERPs can appear above and/or below AI Overviews. Our research shows that out of 279 cases where text ads appeared at the top of AIO-inclusive SERPs (this includes 104 cases where only top text ads were present and 175 cases of top text ad combinations with other ad types) 55.56% of the time (155 keywords), text ads appeared below AIOs, and 44.44% of the time (124 keywords), text ads appeared above AIOs.

Example of text ads above an AI Overview — Text ads above an AI Overview

Example of text ads below an AI Overview — Text ads below an AI Overview

The most common number of text ads above and below AIOs is one ad. 103 keywords from our dataset ended up with one ad below AIOs and 90 keywords resulted in 1 ad above AIOs.

20 keywords had SERPs with two ads below AIOs and 15 keywords had SERPs with two ads above AIOs.

Different combinations of ad types with AI Overviews

How do different ad types appear alongside AI Overviews in various niches?

Note: The number of keywords that trigger ads of a certain type depends on several factors, including the number of queries that triggered AI Overviews in general in a given niche, the number of queries that resulted in AIOs and ads in SERPs, the type of keywords, and niche specifics.

For text ads at the top of the SERPs containing AI Overviews, our research shows that on desktop devices:

Niches like Healthcare, Insurance, and Business have the highest number of keywords triggering text ads at the top of the SERP when accompanying AIOs: 110, 38, and 35 keywords, respectively.
The Career and Jobs, Ecommerce and Retail, Entertainment and Hobbies, and Fashion and Beauty niches triggered zero text ads when accompanying AIOs in SERPs.

How often do text ads appear at the top of the SERPs containing AI Overviews by niche

As for text ads at the bottom of SERPs with AI Overviews, we noticed that:

The Healthcare, Business, and Technology niches have the highest occurrence rate of keywords resulting in ads appearing at the bottom of the AIO-inclusive SERPs: 265, 242, and 185 keywords, respectively.
The Career and Jobs, Fashion and Beauty, and Ecommerce and Retail niches have the lowest number of such keywords: 2, 3, and 3, respectively.

How often do text ads appear at the bottom of SERPs with AI Overviews by niche

As for shopping ads accompanying AI Overviews:

The Pets, Food and Beverage, and Technology niches lead with 87, 62, and 19 keywords that trigger shopping ads alongside AIOs in SERPs.
The Career and Jobs, Cars, Finance, Legal, News and Politics, and Insurance niches had no keywords triggering co-occurences of AIOs and shopping ads in SERPs.

How often do shopping ads appear with AI Overviews by niche

By comparing different ads and how often they appear in various niches, we were able to distinguish leaders among specific ad types:

The Business, Technology, and Healthcare niches have the most text ads appearing at the bottom of AIO-inclusive SERPs but have a very small or zero occurrence rate of shopping ads accompanying AIOs.
The Healthcare, Business, and Insurance niches have the highest number of keywords triggering ads at the top of SERPs with AIOs but have close to zero cases of shopping ads appearing together with AIOs.
The Pets as well as Food and Beverage niches, which have the highest number of shopping ads accompanying AIOs, only have 2 keywords triggering ads at the top of SERPs with AIOs.

Niches that lead in specific ad types accompanying AI Overviews

Do keywords with low CPC trigger ads and AI Overviews in SERPs most often?

We know that keywords with a CPC of $0.5 or less tend to trigger AI Overviews most often. This trend persists if we look at the issue through an advertising lens: keywords with a CPC of $0.5 or less trigger AI Overviews and ads in SERPs more frequently.

How frequently keywords with different CPC values trigger AI Overviews and ads in SERPs

As for the distribution by niche, we observed the same picture. In each niche, keywords with the lowest CPC tend to trigger AI Overviews and ads in SERPs.

Some exceptions occurred depending on the niche:

The Business niche had 44 keywords with a CPC of $2.5 to $3.0 and 43 keywords with a CPC of $3.0 to $4.0 leading to ads and AIOs appearing together, compared to 35 queries with a CPC of $0 to $0.5 leading to the same result.
The Finance niche had 10 keywords with a CPC of $2.0 to $2.5 that resulted in both AIOs and ads in SERPs, and only one case in which a keyword with a CPC of $0 to $0.5 had a similar outcome.
The Healthcare niche had 58 keywords with a CPC from $2.0 to $2.5 triggering AIOs with ads in SERPs and 18 keywords with a CPC of $0 to $0.5.

How frequently keywords with different search volume values trigger AI Overviews and ads in SERPs

The distribution of keywords by niche is more nuanced. Some niches have more keywords with higher search volume values that trigger AIOs and ads in SERPs. For example:

The Cars niche had only one keyword with a search volume from 0 to 50 triggering ads and AIOs in search and 25 keywords with search volumes from 100 to 200 with the same result.
The Healthcare niche had 18 keywords with a search volume from 0 to 50 that triggered AIO and ad combinations in search and 66 keywords with search volumes from 200 to 300 triggering this combination.
The Technology niche had 40 keywords with search volumes from 0 to 50 that led to both AIOs and ads in search and 44 keywords with a search volume from 100 to 200 that led to the same outcome. Niche keywords with higher search volumes also trigger many AI Overviews with ads: 29 queries with a search volume from 500 to 1,000, and 25 queries with a search volume from 1,000 to 10,000.
The Business niche had 35 keywords with a search volume of 200-300, 37 keywords with a search volume of 500-1,000, and 32 keywords with a search volume of 1,000-10,000.

How frequently keywords with different word counts values trigger AI Overviews and ads in SERPs

We observed a significant gap in ads accompanying AI Overviews between the beginning of June (52.20% of searches) and the end of August (13.51% of searches). At the same time, the number of keywords triggering AIOs has increased from 8,718 queries in June to 12,472 queries in August. The SERPs are volatile and Google is constantly making updates and testing new features, so monitoring the situation is critical.

While there is some overlap, most AI Overviews are presented without accompanying ads. This depends on the query type as AIOs usually appear for informational and not commercial keywords. Still, there’s a high ad presence in certain niches, like Pets and Fashion and Beauty, where user queries often align with buying intentions.

Text ads are more commonly found at the bottom of SERPs containing AIOs. This could be Google’s attempt to catch user attention after they engage with AI content and organic results. The less frequent appearance of text ads at the top (both above and below AIOs) may indicate that Google doesn’t want to overshadow the AIOs. As for shopping ads, their appearance below AIOs is consistent with Google’s typical format of placing sponsored results closer to product-related content, not general overviews.

The observation that keywords with lower CPC and search volumes tend to trigger AIOs and ads more often suggests that targeting less competitive keywords, which are generally less expensive, could be a cost-effective strategy. However, this depends on the niche. For instance, the Business and Healthcare niches have a relatively high number of keywords with higher CPC and search volume values leading to ads and AIOs appearing together in SERPs.

The middle length of keywords often strikes a balance between specificity and search volume, making such queries ideal for targeting in PPC campaigns. They are specific enough to drive relevant traffic and broad enough to attract a reasonable number of searches.

In general, the percentage of ads appearing alongside AIOs is currently low (87% of AIOs appear without any ads at all). This suggests that Google may be integrating AIOs into SERPs for keywords that are less commercially attractive. This strategy could ensure that neither businesses nor Google itself lose profit.

Surely, businesses including paid ads in their promotion strategy would benefit more when AIOs aren’t present in SERPs because this makes their ads more visible to users. But as Google keeps rolling out this feature, more and more cases of AI Overviews will be present in searches. Even in this case, ads can be visible because they can be displayed above AI-generated responses. That’s why businesses should improve the visuals and content of their ads to match search intents, attract user attention, and get more clicks.

From an SEO perspective, fewer ads next to AI Overviews is advantageous for organic results because they will need to primarily compete with AIOs for traffic, rather than facing competition from both AIOs and paid ads.

Do AI Overviews contain Google Ads?

In May 2024, Google announced its testing of the inclusion of search and shopping ads directly inside AI Overviews for US users. This means that when an ad is considered relevant, it might appear within the AIO snippet in a dedicated section labeled “Sponsored”.

During our research, we observed several cases where inside some AI Overviews, we’ve identified what we can call “shopping results”—product cards with prices, store information, and other merchant data. These are not marked as ads by Google but could hint at future implementations.

Example of shopping results inside an AI Overview

Our data revealed 14 keywords on desktop devices that triggered AI Overviews with “shopping results” inside. These were keywords from the Ecommerce and Retail, Fashion and Beauty, and Self-Care and Wellness niches. Overall, these shopping results included 374 product cards.

Apart from product cards, you can also see store information, ratings, payment options, delivery information, and a direct purchase link to the product.

Different ad types accompany AI Overviews with product cards inside. The screenshot below displays shopping and text ads above AIOs with shopping results inside the AI-generated snippet.

Example of different ads and an AI Overview with shopping results inside

The inclusion of product cards directly within AI Overviews could be the first step towards integrating direct purchase opportunities within AI-powered answers. This can reduce the steps a user needs to take from discovery to purchase, potentially increasing conversion rates for products featured within these AIOs.

Product details, ratings, store information, etc. directly in the AIO can improve the user experience with Google AIOs by making answers more comprehensive and convenient. This information helps users make informed purchasing decisions without leaving the search results page.

Keywords that trigger these shopping-enhanced AIOs may become more competitive and potentially more expensive. Ecommerce business owners should prioritize product optimization on their websites and add product data to Google Merchant Center accounts. This helps them rank in organic search and appear inside AI Overviews.

How do Google Ads appear with AI Overviews in mobile search results?

In our ongoing exploration of AI Overviews, we’ve expanded our research to examine how AIOs interact with ads on mobile devices. Our research involved a manual analysis of 1,022 keywords, previously identified as triggering AIOs in desktop searches. We checked them within the Google Search Labs environment for a comprehensive view of how ads and AIOs coexist on mobile SERPs.

Our manual research shows that out of the 1,022 keywords analyzed, 70.35% (719 keywords) successfully triggered AI Overviews on mobile devices. 29.65% (303 keywords) did not trigger AIOs.

As for the co-occurrence of ads and AI Overviews in mobile search, only 3.76% of keywords (27 out of 719) showed ads in mobile AIO-inclusive SERPs. 96.24% of keywords (692 out of 719) triggered AI Overviews without ads in SERPs.

Here’s a more detailed breakdown of the appearance of ads and AI Overviews in mobile searches:

12 keywords (44.44%) triggered AIOs accompanied by text ads.
5 keywords (18.52%) triggered shopping ads and AIOs in mobile SERPs simultaneously.
10 keywords (37.04%) resulted in a combination of both text and shopping ads and AIOs.

The most interesting cases where AI Overviews and Google Ads appear together in mobile SERPs

Mobile SERPs for the query, how to choose the best winter suit jacket, contain several blocks of shopping ads followed by an AI Overview. The AI-generated snippet appears at the bottom of the second screen. Combined with several shopping ad blocks, this pushes organic results down the SERP. This example was taken from an account with Search Labs enabled.

We noticed something different after checking this same query from an account without Search Labs enabled. The AIO comes first and is followed by shopping ads.

Here’s another example of ads and AIOs appearing together in the Search Labs environment. The how to choose a hat query triggered a SERP that started with shopping ads containing relevant products. These were followed by three text ads leading to relevant websites. The AI-generated snippet is located under all blocks whose ads exist in various formats.

Checking the same query on the desktop, we see no ads at all with an AIO placed at the top of the results page. The content is also slightly different.

The example below displays four text ads at the top of the SERP and an AIO for the query, best way to buy a new car.

The on athletic shoes query triggered an AIO with shopping results inside the AI-generated box. Located at the top of the SERP is a text ad directing users to the on.com website. Below the ad is an AI Overview with a brief description of the on shoes as well as carts with trending brands. It also displays prices and stores where those items can be purchased. Below the AIO, the on.com website holds the first place in organic search results.

Here’s another interesting example of mobile SERP for the glasses in the sun query. In the screenshots below, you can see that the SERP starts with an AI Overview with many product cards and relevant items. This AIO is followed by several blocks of shopping ads.

According to our data, AI Overviews and ads appear together less frequently on mobile devices. This depends on the keywords chosen for this analysis. We used a combination of search queries with informational, commercial, and transactional intents, each with a different keyword count. In the future, we will investigate the behavior of AIOs in mobile search in more detail, including AIO interplay with ads.

We also observed various combinations of ads and AI Overviews, including shopping ads as well as combinations of shopping and text ads positioned both above and below AI-generated snippets. Additionally, product cards were found inside the AI boxes. There was also a different number of ads in AIO-inclusive SERPs.

Ads are quite visible as they can appear in SERPs above AIOs. But when combined with AI-generated responses, they push organic results further down the search results page. This significantly reduces the likelihood of organic results attracting traffic for these keywords in mobile searches.
