How we vet every listicle
Every agency featured on Web Tonic passes our 84-point editorial review before a single listicle goes live. This is how we vet each pick:
Verified client outcomes: We require real case studies with measurable KPIs — revenue, ROAS, CPA, retention — tied to the exact category being ranked. No cherry-picked wins, no unverifiable numbers.
Independent reputation: We cross-check Clutch, Google, G2, and Trustpilot ratings, and screen for review-bombing or suspicious patterns. Only operators with a consistent, verifiable track record make the cut.
Beyond that, every listing goes through a quarterly re-audit. We check 84 criteria across 6 pillars to make sure it still holds up — here are some of the checks we run:
A generative engine optimization agency works on whether ChatGPT, Google's AI results, Perplexity and similar assistants name your brand when someone asks for a recommendation: it fixes how your site states facts, builds the comparison and documentation pages models quote, earns mentions on sources they trust, then samples the assistants to see what changed.
Every firm below was read on its own site, not on a directory profile. Thirteen external firms publish generative or AI search work and B2B SaaS work in their own words, and thirteen of them publish a headquarters address across two countries.
What does a generative engine optimization agency do for software companies and B2B SaaS teams?
It makes a brand quotable by AI assistants: clarifying facts on the site, building comparison and reference pages models cite, earning third-party mentions, then sampling assistants for change. Thirteen external firms here publish B2B SaaS work.

Frequently Asked Questions
Why do AI assistants describe our product wrong?
Usually because the assistant is reading third-party comparison posts, review-site profiles and old release notes rather than your documentation, and nothing on your own site states the facts plainly enough to override them. The fix is unglamorous: current pricing and positioning pages, a maintained docs site, structured product data, and enough independent coverage that the model sees the same claim in several places. Ask a firm which wrong claim it corrected last, and where the correction actually came from.
Is this just SEO with a new label?
It overlaps heavily, because assistants still lean on crawled pages, but the deliverables differ. Classic SEO chases a ranking position for a query; generative work chases inclusion in an answer that cites three or four sources, which puts weight on entity clarity, comparison content, documentation and off-site mentions. Ask what a candidate measures, how often it samples the assistants, and whether it can show a prompt set where your product moved from absent to cited.
What does this work usually cost?
Fees arrive as a one-off visibility audit, a content and entity programme billed monthly, or a line inside a wider search retainer, and monitoring tools are sometimes billed separately. Scope moves a quote most: number of prompts tracked, pages rewritten and approvals required. On this page not one external firm here publishes a fee figure on its own site. Ask what a month contains, how many prompts are sampled, and who writes the content.
Which of these firms name a client I can verify?
Thirteen of the thirteen. GrowthSpree names Hasura and Privado, and NoGood names Nike and TikTok. The rest credit nobody on the pages we read, which is common when a brand forbids logo use or the work sits under a parent agency. Ask instead for two accounts the firm works on now, a redacted prompt-tracking report, and a call with the marketer who approved the invoice. A firm that cannot arrange that call may be describing work it no longer holds.
Should the agency doing our SEO also own AI visibility?
Usually yes, because the same pages, entity data and mentions drive both, and splitting them duplicates work. The risk is a supplier grading its own homework on a metric nobody standardises yet. Ask for raw prompt logs, not a score, and read them yourself; our approach sits in how we run GEO and AEO.
Choosing a Generative Engine Optimization Partner for B2B SaaS Brands
All thirteen external firms here publish generative or AI search work alongside B2B SaaS work on their own sites, which is a lower bar than a proven result in your category. Treat this as a shortlist to interrogate, not a ranking of outcomes.
Thirteen credit a client you can check, and not one external firm here publishes a fee figure on its own site. Compare what each firm will actually own: the prompt set, the content, the structured data, the off-site mentions and the reporting.
Ask for the prompt log behind the last account the named team worked on, before and after. A firm answering with dated prompts, cited sources and the pages it changed is describing its own work; a firm answering with a proprietary visibility score is not.
Whoever wins the brief, keep the content, the structured data and the monitoring account in your own name, because a visibility number you cannot reproduce is a number you cannot defend. If you would rather have the AI visibility work, the organic search it rests on and the growth programme around it run by one accountable team, read our latest analysis or see how we run paid search.
