The "AEO agency" search results have changed hands eight times in under two months. New providers appear weekly. DIY tools promise to handle answer engine optimization for a fraction of the cost. If you're a business owner trying to get cited by ChatGPT, Perplexity, or Gemini, the first decision is: hire someone or do it yourself?
This is not an abstract comparison. We run AEO on our own companies — ShopProp Realty (real estate, est. 2007, 8 states) and AskBeforeYouEat (consumer nutrition) — so we know what the work actually involves and where DIY breaks down.
Before comparing options, you need to know what the work is. Getting cited by AI assistants requires five distinct capabilities running in parallel:
brand-facts.json with canonical claims: pricing, service area, founding date, specialties. The anti-hallucination layer.The question is whether you handle these five layers yourself or pay someone to handle them.
| Capability | DIY AEO tools | AEO agency / service |
|---|---|---|
| Schema markup | Schema generators exist (free–$50/month). You implement, validate, and maintain them yourself. | Done for you. Updated when your business changes. |
| llms.txt | Write it yourself — no tools exist to generate it automatically. Most businesses don't know the format exists. | Created, deployed, and maintained. Updated when facts change. |
| brand-facts.json | Write it yourself. No mainstream tool supports this format yet. | Created from your business data, deployed, kept current. |
| Content architecture | AI writing tools (Jasper, Copy.ai) can generate text. You decide what to write, structure it for citations, and publish it. | Content strategy, creation, and deployment handled as a system. |
| Citation monitoring | Manual: ask ChatGPT/Perplexity your target queries weekly, record results in a spreadsheet. No mainstream tool automates this across all platforms. | Automated multi-platform monitoring with trend tracking. |
| SEO integration | Separate tools. You coordinate keyword tracking, ranking data, and AEO results yourself. | Integrated: SEO and AEO data feed each other. |
| Ongoing maintenance | You. Schema breaks when you update your site. llms.txt goes stale. Brand facts drift. | Continuous: updates trigger across all AEO artifacts automatically. |
| Typical cost | $0–$100/month in tools + 8–15 hours/month of your time | $499–$3,000/month, zero hours of your time |
DIY AEO is viable if all of these are true:
If you're a technical founder with time, DIY AEO is a legitimate option for the first 3–6 months. The foundational artifacts (schema, llms.txt, brand-facts.json) are one-time setup. The ongoing work is content and monitoring.
Three patterns we've seen repeatedly when businesses try DIY AEO:
The hardest part of AEO isn't the initial setup — it's keeping everything current. Your pricing changes. You add a service. You hire someone. Every change needs to propagate across schema, llms.txt, brand-facts.json, and all content pages. In practice, businesses do the initial setup and then the artifacts go stale within weeks. Stale AEO data is worse than no AEO data — it trains AI assistants to cite outdated information about your business.
There's no mainstream tool that automatically monitors your citations across ChatGPT, Perplexity, Gemini, Claude, and Brave Search simultaneously. DIY monitoring means manually querying each platform weekly, recording results, and comparing trends. It takes 2–3 hours per week to do properly. In practice, it gets done enthusiastically for two weeks and then stops.
AI writing tools can generate text. What they can't do is decide: which comparison pages to build, how to structure content for citation extraction rather than ranking, when to use guide format vs. blog format, and how to interlink pages so AI crawlers understand your topical authority. These are strategy decisions that compound — a wrong architecture is hard to fix later.
At 10 hours/month and a conservative value of $75/hour for a business owner's time, DIY AEO costs $750/month in opportunity cost — plus any tool subscriptions. An AEO service at $499–$999/month often costs less when you account for the time you're not spending on implementation and monitoring. The calculation changes if you genuinely enjoy the technical work or have a team member with spare capacity. But most business owners underestimate the ongoing time commitment.
If you decide to hire, the AEO agency market is volatile and fragmented — eight #1 position changes in two months means no provider has established category dominance yet. Here's how to separate real from marketing:
provider.com/llms.txt. If they sell AEO but don't have a live llms.txt file on their own site, they haven't built one for a client either.For our complete evaluation framework, see the AEO agency guide.
The agency-vs-DIY framing misses a third category that didn't exist two years ago: AI growth engines that handle AEO as part of a broader automated system alongside SEO, content, lead capture, and reporting.
This is what TruePrime Go does. The AEO layer — schema, llms.txt, brand-facts.json, structured content, citation monitoring — runs automatically alongside keyword tracking, content deployment, and lead capture. It's not a standalone AEO service; it's AEO integrated into the full growth pipeline.
Plans start at $499/month. First payment after 30 days. Cancel anytime. The same system runs on our own companies — these pages are proof of it working.
Get AEO + SEO + lead capture in one system| Your situation | Best path | Why |
|---|---|---|
| Technical founder, small query set, have 10+ hrs/month | DIY for 3–6 months, then re-evaluate | Learn the mechanics, build foundation artifacts yourself, switch to a service when time becomes the bottleneck |
| Already have SEO handled, need AEO layered on | Standalone AEO agency ($500–$3,000/month) | Focused AEO expertise complements existing SEO program |
| Need SEO + AEO + content + lead capture | AI growth engine ($499–$999/month) | One system, one cost, all layers coordinated. Lower total cost than agency + tools separately |
| Enterprise with dedicated marketing team | AEO agency + in-house SEO | Your team handles strategy, the agency handles AEO implementation and monitoring |
Regardless of which path you choose — DIY, agency, or growth engine — the citations come from the same signals:
The tools and services are means. The citations come from the work.
