Measure
We sample your category’s buyer-intent prompts across all five engines and score your AI Share of Voice against Boston and global competitors.
Word of GPT is a Generative Engine Optimization (GEO) agency serving Boston-based companies. We measure your AI Share of Voice across ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews, then build the content and distribution to win the answer in the Boston market.

In July 2026 we asked ChatGPT, Perplexity and Google the exact question a Boston buyer would ask — “best generative engine optimization agency in Boston” — and recorded every agency they named. This is that raw result, including the part that doesn't flatter us.
“Home page go to home page See What's Next open menu Services Answer Engine Optimization (AEO) Advanced…”
“Marketing Agency | Synapse Services Services Paid Search SEO AI Search Content Marketing Paid Social Organic…”
“Found on Google & AI Search | Webvello SEO & GEO Skip to main content USA-Based Digital Agency | SEO…”
Method: one query per engine via a real browser, July 2026. Every agency above was then loaded independently and had to (1) state an AI-search offering on its own site — the quote is from that page — and (2) name Boston. Answers drift; this is a snapshot, not a standing. Full methodology →
Boston concentrates biotech, life sciences, enterprise software and a dense academic research base. Buyers are evidence-driven and unusually likely to check the primary source behind a claim.
Boston's buyers check the primary source behind a claim, and in regulated categories an AI engine stating something wrong about you is a commercial problem, not just a visibility one. Accuracy and authority carry more weight here than almost anywhere.
Evidence-driven buyers in regulated categories reward sources that are authoritative and verifiable — and punish vendors whose AI-stated facts don't check out.
These are the actual queries buyers type into ChatGPT, Perplexity, and Google when researching GEO services in Boston. We sample each across all five engines as part of an audit:
Real agencies the AI engines cite for "Boston GEO agency" and related queries. We track each of them in our 5-engine prompt corpus so your audit shows exactly where they out-cite you — and where you out-cite them.

Generative Engine Optimization (GEO) is the practice of getting your brand mentioned, cited, and recommended inside AI answer engines — ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews. For Boston-based companies, GEO is the discipline that decides whether you show up in the AI-generated shortlist a buyer builds before they ever visit your site.
Our GEO Visibility Audit in Boston is $3,000–$7,000, delivered in about a week, and benchmarks you against 3 named competitors across 5 AI engines and 200–500 buyer-intent prompts. Ongoing GEO retainers for Boston-based brands run $8,000–$20,000 per month on a 6-month minimum. Start with a free one-page Boston AI visibility snapshot.
We won't invent a number. We looked for primary evidence on time-to-first-citation and found none — the "60–120 days" figure this industry quotes is a vendor convention, not a research finding. What we can say: technical fixes like per-engine crawler access land within days, and because we sample every prompt repeatedly, any change in your Boston mention and citation rates shows up in weekly reporting. Boston-based teams watch the real curve instead of trusting our forecast. See /evidence for the full grading.
We track all five major answer engines for Boston-based businesses — ChatGPT (OpenAI), Claude (Anthropic), Perplexity, Gemini (Google), and Google AI Overviews — sampling each multiple times over a 14-day window. Single-shot answers are noisy; we report stable results.
Yes. We sample and optimize prompts in the languages your Boston buyers actually use. In Boston that means English. Bilingual GEO doubles the addressable prompt volume and is a real edge in markets where most agencies only optimize English.
In Boston the named GEO agencies we benchmark against include: ovrdrv.com, Synapse, Webvello. We track each of them in our 5-engine prompt corpus so you can see exactly where they out-cite you, and where you out-cite them. See the full buyers' guide at /geo-agencies.
