How to Choose the Best GEO Agency: 2026 Evaluation Scorecard

November 9, 2026

To choose a generative engine optimization (GEO) agency, score each candidate from 0 to 3 on eight criteria: AI search depth, measurement, proof of results, content and earned-mention execution, scope and contract clarity, leadership, industry fit, and honest claims. Google’s own guidance for hiring a search consultant adds a rule that applies to GEO too: no one can guarantee a #1 ranking, so treat any guaranteed placement as a reason to walk away (Google Search Central).

This guide gives you the scorecard and the questions to ask on a sales call, plus the red flags to watch for. Disclosure: Genevate is a GEO agency, so you may end up comparing us with others. The scorecard works the same way for every agency, including ours.

Key Findings

Google says no one can guarantee a #1 ranking and warns against SEOs who claim a “special relationship” with Google (Google Search Central, updated June 5, 2026).
Google’s hiring guidance asks whether an agency’s GEO advice matches Google’s official guidance on generative AI features (Google Search Central).
Google says AI Overviews and AI Mode need no special markup, AI text files, or extra schema (Google Search Central).
WebFX states that “no generative engine optimization agency, contractor, or freelancer can guarantee placements.”
Contract terms vary: WebFX asks for 6 months, Breaking B2B offers 6 or 12 months, and Siege Media uses 12 months with a 30-day out clause (agency pricing pages, checked Nov 5, 2026). Genevate works month to month.
Across 95 websites, organic search sent 39 times more sessions than AI assistants, so ask any agency how it reports both (The SEO Works, Sept 2025 to Aug 2026).

The GEO Agency Evaluation Scorecard

Each criterion gets a score from 0 (no evidence) to 3 (clear, checkable evidence). The table lists what to ask, what a strong answer sounds like, and what should worry you.

Criterion	Ask the agency	Strong answer (3)	Red flag (0)
AI search depth	Which AI platforms do you work on, and what do you change on a client’s site and off it?	Lists platforms such as ChatGPT, Perplexity, Google AI Overviews, and Copilot, and describes specific work for each	GEO is one line inside an SEO package
Measurement	How do you track AI visibility, and how do you tie it to leads?	Describes a prompt set, a tracking method, a reporting schedule, and a link to qualified leads	Reports only “mentions” with no method
Proof of results	Can I speak with past clients?	Offers references and describes results with dates and scope	Only logos, no references
Execution	Who writes the content, and how do you earn third-party mentions?	Lists the content and earned-media work included each month	Advice only, with all work left to your team
Scope and contract	What is the minimum term, and who owns the content and data if we leave?	States term, out clause, and ownership in writing	Will not discuss terms before you sign
Leadership	Who does the work, and what have they published?	Named team members with a public track record	No names, or work handed off after the sale
Industry fit	Which clients are like us?	Relevant industry pages or named, comparable clients	No work in your sector
Honest claims	What can you promise?	Promises a method and reporting, not a placement	Guarantees AI placements or a #1 result

Source: criteria are Genevate’s editorial framework, built from Google’s hiring guidance and the public service pages cited below.

Key Findings

Eight scores of 3 give a maximum of 24, but a 0 on honest claims should end the search.
Ask every agency the same questions in the same order, so the scores can be compared.

How to Weight the Scorecard

Not every criterion deserves the same weight. The weights below are our editorial suggestion for a mid-market or enterprise buyer, and you should change them to fit your goals.

Suggested weights for the eight GEO agency scorecard criteria, out of 100 points

Criterion	Suggested weight (points out of 100)	Why it carries that weight
AI search depth	20	GEO is the service you are buying
Measurement	15	Without a method, you cannot judge the work
Proof of results	15	Past work with references is the best predictor available
Execution	15	AI engines read content and third-party mentions, so someone has to produce both
Scope and contract	10	Terms decide how much risk you carry
Leadership	10	Senior people should do the work you were sold
Industry fit	10	Familiarity with your buyers shortens the learning curve
Honest claims	5	Low weight, but a 0 disqualifies the agency

Source: Genevate editorial suggestion. Multiply each 0 to 3 score by weight, divide by 3, and add the results for a score out of 100.

Key Findings

The three heaviest criteria (AI search depth, measurement, and proof) add up to 50 points.
Honest claims carry the fewest points because it works as a pass or fail test.

Questions to Ask a GEO Agency

Google’s guidance for hiring a search consultant lists questions that carry over to GEO (Google Search Central). Use these on the first call.

What results do you expect, in what timeframe, and how do you measure success?
What is your experience in my industry?
How long have you been in business, and who will do the work?
Will you share every change you make, with the reasoning behind it?
Can I contact past clients?
Which AI platforms do you track, and how many prompts?
How do you report AI referral traffic and conversions in GA4?
What is the minimum term, and is there an out clause?
Who owns the content and the tracking data if we leave?
Does your advice match Google’s official guidance on generative AI features?

Genevate publishes its own answers to several of these. Its FAQ describes a three-phase process (strategy in month 1, content execution from month 2, then ongoing measurement) and says engagements are ongoing retainers tailored to each client. Genevate runs those retainers month to month, with no long-term contract.

You can read how that applies to your category on the generative engine optimization services page.

Red Flags When Hiring a GEO Agency

Google lists the warning signs for search consultants. Each one applies to GEO agencies.

Red flag	What Google or the agency itself says
Guaranteed placement	“No one can guarantee a #1 ranking on Google” (Google Search Central)
Claimed special access	Beware of SEOs that allege a “special relationship” with Google or advertise a “priority submit” (Google Search Central)
Secrecy	“Be careful if a company is secretive or won’t clearly explain what they intend to do” (Google Search Central)
Required special files or markup	Google says no new machine-readable files, AI text files, or special schema are needed for AI Overviews and AI Mode (Google Search Central)
Link schemes	Google says to avoid SEOs that talk about link popularity schemes (Google Search Central)
Placement promises from GEO agencies	“No generative engine optimization agency, contractor, or freelancer can guarantee placements” (WebFX)

Source: Google Search Central, “Do You Need an SEO? Tips for Hiring an SEO” (updated June 5, 2026) and “Optimizing your website for generative AI features on Google Search”; WebFX service page.

Key Findings

Google and at least one large agency agree that placement guarantees are a warning sign.
An agency that sells AI-specific files or markup as a requirement is contradicting Google’s published guidance for its own AI features.

What the Contract Should Say

Agencies publish very different terms. The table shows three agencies that post them, plus Genevate’s own term.

Agency	Published term	Source
WebFX	6-month commitment	WebFX
Breaking B2B	6 or 12 months, with a lower monthly rate on the 12-month term	Breaking B2B
Siege Media	12 months with a 30-day out clause	Siege Media
Genevate	Month to month, no long-term commitment	Genevate

Source: each agency’s own page, checked Nov 5, 2026. The Genevate row states our own terms.

A long minimum term protects the agency more than the client. Genevate works month to month because we expect the results to be the reason clients stay. If the work stops producing measurable gains in AI visibility and qualified leads, a client can leave without waiting out a contract.

Before you sign, get four items in writing: the minimum term, the exit terms, the content and data ownership, and the reporting you will receive each month. Our GEO pricing guide compares published agency prices and engagement models if you are building a budget alongside this scorecard.

Ask How the Agency Measures Results

AI referral traffic is still small, so a good agency reports more than clicks. The SEO Works found that across 95 websites, organic search delivered 39 times more sessions than AI assistants from September 2025 to August 2026 (The SEO Works). Marie Haynes found that 45 of 100 sites she sampled tracked no key events at all (Marie Haynes).

Those two findings suggest three questions for any agency:

Which conversions will we track, and are they set up before the work starts?
How do you report AI-assisted visits that arrive through branded search or direct traffic?
How do you report Google AI Overviews, which reach your site as ordinary organic sessions (The SEO Works)?

For background on the AI search numbers behind these questions, read our AI search statistics report and the Google AI Overviews statistics.

Frequently Asked Questions

How do I choose a GEO agency?

Score each candidate from 0 to 3 on AI search depth, measurement, proof of results, execution, scope and contract, leadership, industry fit, and honest claims. Ask all of them the same questions, and drop any that guarantee a placement. Google Search Central says no one can guarantee a #1 ranking.

What questions should I ask a GEO agency?

Ask about expected results and timeframe, experience in your industry, who does the work, which AI platforms they track, how they report conversions, contract terms, and data ownership. Google’s hiring guidance also suggests asking whether you can contact past clients.

Can a GEO agency guarantee that my brand appears in ChatGPT?

No. WebFX says no GEO agency, contractor, or freelancer can guarantee placements, and Genevate’s FAQ says no ethical GEO agency can guarantee specific AI placements. AI platforms decide what to show, and those decisions change as models update.

Does my GEO agency need special files or markup for Google AI features?

Google says no. Its documentation states that you do not need new machine-readable files, AI text files, or special schema.org markup to appear in AI Overviews and AI Mode (Google Search Central). Standard SEO fundamentals still apply.

How long should a GEO contract be?

Published terms range from month to month up to 12 months. WebFX asks for 6 months, Breaking B2B offers 6 or 12, and Siege Media uses 12 months with a 30-day out clause. Genevate works month to month with no long-term commitment. Ask for exit terms in writing.
