Generative engine optimization services are paid work to get your brand credited in the answers ChatGPT, Perplexity, Gemini and Google AI Mode write. SERP Masters is an SEO agency, run by founder Andy Wang, that sells this work to companies whose buyers shortlist vendors inside AI answers. Work starts with a source-pool map: the domains each engine credits on your buyers’ prompts. Passage rewrites, structured data and third-party mentions then target each gap, reported per engine. Terms are month to month.

Citation figures are de-duplicated across Ahrefs, DataForSEO and live renders. Ranking and citation outcomes cannot be projected with certainty.
Your page still ranks on Google. The clicks are thinner anyway. Ask Perplexity for the vendors in your category, then check whether the answer credits you or a directory and two competitors.
That gap is a source-pool problem. Each generative engine writes from its own short list of trusted pages. SERP Masters runs generative engine optimization (GEO) inside its AI SEO program, aimed at your pages and at the third-party pages that describe you.
The telehealth SEO case study shows the split: 1,100+ Google AI Overview citations, 114 in ChatGPT and 29 in Perplexity. A blended score would have hidden that spread, so SERP Masters scores each engine on its own line. Andy Wang does the work on every engagement. The service itself is defined next.
What are generative engine optimization services?
Generative engine optimization services, also sold as AI search optimization services, target one decision: which sources an AI engine credits in its answer. A generative engine is a large language model with live search attached. It runs query fan-out into related searches, retrieves candidate pages and credits a handful of them. GEO makes a brand one of those credited sources and checks that the engine states its facts correctly.
The GEO definition and background covers the term’s origin. As a service, GEO adds two things to traditional SEO groundwork: a map of the sources each engine cites for your buyers’ prompts, and a plan to earn a place in those pools.
GEO vs SEO vs AEO: what each one competes for
GEO, SEO and AEO (answer engine optimization) share one technical foundation and compete for different results: SEO for ranked positions, AEO for the single extracted answer and GEO for a credited slot in a multi-source response.
SERP Masters runs all three on the same pages, since an engine will not cite a page it cannot crawl and trust. Each pairing has its own comparison: GEO vs SEO and AEO vs GEO.
AEO is the sibling service: it shapes the short answer Google lifts into a snippet, and GEO takes over when an engine writes a longer response and must decide whom to credit. SERP Masters usually scopes the answer engine optimization service and GEO together.
How do generative engines choose which sources to cite?
Generative engines choose sources in four stages, and a brand can drop out at any of them.
Retrieval is where the engines split, so a brand cited in Perplexity can be missing from Copilot on the same prompt. SERP Masters logs the domains each engine credits per panel prompt, and that log decides where the work goes.
Who needs a GEO agency?
A GEO agency, sometimes billed as an AI search optimization agency, fits companies whose buyers ask an AI engine for a shortlist before they contact a vendor. Three situations fit best.
GEO is a poor fit if you need a guaranteed citation or a date for results: no engine sells placement.
What is included in SERP Masters GEO services?
SERP Masters GEO services include eight deliverables, each owned by Andy Wang and visible in the monthly reporting.
“I didn’t even know structured data existed. SERP Masters added it across the whole site and our listings started showing up richer in the results. Andy handled an entire layer of this I’d never have known to ask for.”
How SERP Masters delivers GEO services
SERP Masters delivers GEO through its five-step method: Diagnose, Architect, Execute, Corroborate, Measure. Andy Wang runs each step or directs your in-house team.
The Diagnose step also runs as a standalone per-engine audit for a baseline before you commit.
How SERP Masters measures GEO results
SERP Masters scores GEO results as citation-presence rate on a fixed prompt panel, per engine and never blended. A prompt counts when your brand is a credited source or is named in the answer, and the competing domains are logged beside it.
A combined score can climb on Perplexity while Copilot drops to zero, so the report carries seven lines: Google AI Overviews, Google AI Mode, ChatGPT, Perplexity, Gemini, Copilot and Grok. Mention accuracy is the second metric: a citation that repeats an old price goes on the gap list.
Citation tracking saves each answer and de-duplicates it against Ahrefs, DataForSEO, Keyword.com and Semscraper data. Clicks and impressions come from Google Search Console; analytics carries AI referral traffic. The AI visibility tools page compares the trackers.
What results have SERP Masters GEO clients seen?
SERP Masters clients are cited today on 5 of the 6 sites that had zero AI citations a year earlier. Client names stay private until each client agrees.
An ecommerce store earned AI Overview citations on commercial queries after a structured data fix and a GEO layer (ecommerce AI SEO case study). Every published result is on the case studies page.
What do generative engine optimization services cost?
Engagements are quoted after the free audit, on month-to-month terms. The quote follows the Diagnose step and reflects the measured gap on each engine.
Five drivers move the cost:
One dependency sits outside SERP Masters: corroboration needs third parties to publish on their own schedules. Month-to-month terms tie the engagement to the per-engine report.
How to choose a generative engine optimization agency
A generative engine optimization agency should show its measurement method, who does the work and evidence with a baseline before any contract.
Two objections come up often. “AI answers will replace search” misreads the mechanism: engines retrieve from search indexes, so GEO builds on SEO. “We tried an agency before” gets a specific answer: the per-engine report names what moved on each engine and what did not.
Watch for a guaranteed ChatGPT or AI Overview placement, which no engine sells, and mass-produced AI content, which carries spam-policy risk for rankings and AI visibility alike.

Answered the way an engine would extract it.
Each answer opens with the answer. The FAQPage schema is generated from these fields and nothing else.
01Can ChatGPT help with SEO?
ChatGPT helps with SEO in two separate roles. As a tool, it drafts outlines and clusters prompts, and a person still checks every fact. As a channel, it is one of the engines a GEO program measures: SERP Masters records which domains ChatGPT credits for each panel prompt and works to add your brand to that list.
02How long does generative engine optimization take to show results?
Generative engine optimization has no fixed timeline, and SERP Masters does not forecast one. Engines refresh retrieval at different speeds, and corroboration depends on third parties publishing. SERP Masters sets a per-engine baseline in the Diagnose step and reports movement against it every cycle, so you see what changed and on which engine.
03Can a small business use GEO services?
Small businesses can use GEO services when their buyers ask AI engines for local or niche recommendations. Gemini and Google AI Mode local answers draw on Google Business Profile data, reviews and consistent business details, and SERP Masters has managed 700+ Google Business Profiles. A small business usually needs a smaller prompt panel, which lowers the cost of measurement.
04Do backlinks still matter for generative engine optimization?
Backlinks still matter for generative engine optimization. Links help pages rank and get retrieved in the first place, and GEO adds a second need for unlinked brand mentions, because an engine checks whether other sources state the same facts. SERP Masters plans links and mentions together and aims both at the sources each engine already cites for your buyers’ prompts.
05Why does ChatGPT cite a competitor instead of us?
ChatGPT cites a competitor when that competitor’s pages, or third-party pages about it, answer the fan-out questions more directly and other sources confirm them. SERP Masters starts with the source-pool map, records which URLs ChatGPT credits for the prompt, then targets the gap with a clearer passage, an original figure or a corroborating mention.
06Does adding an llms.txt file help with generative engine optimization?
An llms.txt file is optional housekeeping, and SERP Masters does not sell it as a citation lever. Crawler access matters more: robots.txt rules, firewall settings and JavaScript rendering decide whether AI crawlers can read the page at all. SERP Masters checks access first and adds llms.txt when a client asks for it.
