How We Chose These Agencies
We did not invent scores, rankings, or client outcomes. Every agency featured below was evaluated using publicly available information: agency websites, verified review platforms such as Clutch and G2, and independent industry roundups. Where an agency’s own marketing claims a result (a percentage lift, a revenue figure, a client name), we’ve labeled it as agency-reported rather than independently verified.
We looked at five factors above all else when building this list:
- Services & expertise: does the agency specialize in AI SEO, or is it a generalist offering it as one line item among many?
- Reviews & reputation: what do verified third-party reviews (Clutch, G2, Google) say, and how many reviews back that rating up?
- Transparency: does the agency publish pricing, contract terms, or reporting practices, or is everything gated behind a sales call?
- Track record: how long has the agency operated, and does it have documented case studies or client results?
- Communication & fit: does the agency describe a clear point of contact, reporting cadence, and onboarding process?

How to Choose the Right AI SEO Agency
Before hiring any of the agencies above, confirm they have genuine, documented experience with small-business budgets and internal teams, not just a large enterprise SEO practice that added an “AI SEO” line item to its services page. Ask for at least two references from businesses close to your own size and industry.
Small businesses have different needs than enterprise buyers evaluating the same kind of agency: lower budgets, fewer internal marketing resources to manage the relationship, and less tolerance for a slow, multi-month onboarding process. Look for agencies that publish transparent, tiered pricing rather than requiring a sales call just to learn the starting rate, and that offer month-to-month or short-term contract options rather than locking you into a 12-month agreement before you’ve seen results.
Weigh pricing against scope rather than chasing the lowest number. Gushwork’s published plans start at $800/month and Third Marble Marketing’s Basic tier starts at $499/month, while SmartSites and WebFX price custom scopes without a public starting rate; a lower headline price isn’t automatically the better deal if it buys you less content production or slower reporting, so ask each finalist to itemize exactly what’s included at their proposed price point.
Finally, before signing anything, get agreement in writing on how success will be measured. AI search optimization is newer than traditional SEO, so ask specifically how the agency tracks citations or mentions inside tools like ChatGPT, Google AI Overviews, and Perplexity (not just traditional keyword rankings), and how often you’ll receive reporting against those metrics.
Final Thoughts
All six agencies above have demonstrated experience helping small businesses build visibility in AI-powered search, but the right fit depends on your budget, how much of the work you want automated versus handled by a dedicated strategist, and how quickly you need to get started. A platform-driven option like Gushwork can suit a business that wants a low, published entry price, while a strategist-led model like Searchbloom may suit a business that wants closer, more consultative attention. None of the pricing, review counts, or case study figures above should be treated as a firm quote or guarantee. Confirm current pricing, scope, and references directly with each agency before signing anything.

What’s the difference between AI SEO and traditional SEO for a small business?
Traditional SEO focuses on ranking in classic search engine results pages, while AI SEO (also called GEO or AEO) focuses on earning citations and mentions inside AI-generated answers from tools like ChatGPT, Google AI Overviews, and Perplexity. Most small businesses still need both, since traditional organic search continues to drive the majority of website traffic for most industries as of the time of writing.
