Comparison table of the 7 best AI Overview agencies
The table summarizes the rankings from first to seventh place. It indicates each agency's location, the nature of its AI Overview offering, and the type of business it is best suited for.
Our ranking criteria
We selected six criteria observable on each agency's website, excluding unverifiable reviews. Every ranked agency provides an explicit GEO or AI Overview offering, rather than just a mention in a list of services.
- Citation monitoring:tracking brand presence in AI Overviews and other AI engines across a defined set of queries.
- Visibility audit:dated reports on queries that trigger an AI Overview and the sources cited instead of you.
- Editorial and technical methodology:content structure, structured data, and indexing.
- Authority signals:work on brand mentions in third-party sources.
- Published client case studies:results measured in AI visibility.
- Engine coverage:AI Overviews, AI Mode, ChatGPT, Perplexity, Gemini.
datashake comes out on top because it ticks these six criteria. Furthermore, it publishes quantified results on its clients' AI visibility, something few agencies are doing yet.

What is an AI Overview and why does it matter?
An AI Overview is a response written by Google's AI that appears above organic search results, including links to its sources. It is generated by Gemini using pages already indexed by Google, making the AI Overview a new form of generative search integrated directly into the engine.
Since the launch on July 22, 2026, the impact is measured in clicks. According to analysis by datashake, in e-commerce, guides and comparison articles have seen a 15% to 30% drop, while transactional queries have proven more resilient. Our article onAI Overviews in Francedetails the impact sector by sector.
AI Mode, launched on the same day, takes this logic further with a fully conversational tab. Queries here are longer and often comparative, which increases the importance of being cited in rankings and comparisons within your sector.
SEO, GEO, and AI Overviews: what are the differences?
SEO targets positioning in traditional search results. GEO, or Generative Engine Optimization, targets citations within AI-generated responses, whether from Google, ChatGPT, Perplexity, or Gemini.
AI Overviews sit between the two: they rely on Google's index, and therefore on SEO, but their selection logic is that of GEO. To learn more, our guide ondefining GEOlays the groundwork.
How can you get cited in AI Overviews?
To build an AI Overview, Google doesn't just query its index once. It breaks the question down into sub-queries—a principle known as query fan-out—and then assembles an answer using the most useful pages for each one.
Several levers can increase your chances of being selected:
- Direct answers:a clear definition or verdict in the first paragraph of every section.
- Extractable structure:explicit headings, lists, tables, and sourced data.
- Structured data:consistent Schema.org markup, detailed in our guide onstructured data.
- Trust signals:identified authors, demonstrated expertise, and reliable sources, following the logic ofE-E-A-T applied to GEO.
- Authority signals:brand mentions in media, rankings, and comparisons that Google reads within your market.
These levers cannot be managed blindly. You need regular citation monitoring to see what works, andGEO toolsadapted for tracking AI responses.

How do you choose an AI Overview agency?
To choose an AI Overview agency, start by requesting a visibility audit for your business queries: it quickly shows whether the agency knows how to measure citations. Then, compare proposals based on verifiable criteria, using the same framework as forchoosing your GEO agency.
Questions to ask during meetings
- What set of queries or prompts will you use to measure my visibility, and how often?
- Which engines do you track: AI Overviews, AI Mode, ChatGPT, Perplexity, or Gemini?
- Can you show me client case studies with results measured in AI visibility?
- How do you manage mentions of my brand outside of my own website?
Red flags
- A promise of guaranteed citation in AI Overviews: Google alone controls the generation.
- Reporting limited to rankings, without measuring citations.
- No client case studies with quantified AI visibility.

How much does an AI Overview agency cost?
The price depends on the number of tracked queries, the volume of content to be reworked, and the reputation-building work to be carried out off-site. Few agencies publish their rates, and most provide a quote after an initial audit.
Several players in the ranking offer this initial diagnosis for free: a 30-minute live audit at datashake, and a free audit with a response within 48 business hours at AEP Digital. Astrak, for its part, lists SEO services starting at €900, with GEO included in the same support package.
Compare quotes based on the same scope: number of queries and search engines tracked, reporting frequency, optimized pages, and reputation-building actions. A low price without citation monitoring makes it impossible to measure return on investment.
