How to Choose an SEO Agency in 2026: AEO Agency vs SEO Agency vs In-House Hire
Choose by who does the work and how it's measured: an in-house hire for steady work you can manage, an SEO agency when rankings are the gap and your team can publish, an AEO or GEO agency when buyers ask AI which product to pick. A side-by-side table, 11 questions to ask, and the red flags Google itself lists.
How do you choose between an AEO agency, an SEO agency and an in-house hire? The short answer
Choose by who will do the work and how it gets measured: hire in-house when you have steady work and someone to manage the hire, use an SEO agency when your gap is rankings and your team can write and publish, and use an AEO or GEO agency, or one program that runs both, when buyers already ask AI assistants which product to pick and you need finished pages measured against signups. Whichever you choose, walk away from anyone who guarantees rankings or AI citations. Google's own guidance says "No one can guarantee a #1 ranking on Google," and nobody controls what a model says either.
The labels matter less than they look. Google says there are "no additional requirements" and no "special optimizations" needed to appear in AI Overviews or AI Mode beyond normal SEO fundamentals. AEO and GEO agencies add prompt tracking, answer-shaped pages and off-site work for the assistants that search the web, but most of the work underneath is the same.
AEO agency vs SEO agency vs in-house hire, side by side
| SEO agency or consultant | AEO or GEO agency | In-house hire | |
|---|---|---|---|
| Best when | Rankings are the gap and your team can write and publish | Buyers ask ChatGPT, Claude, Perplexity or Google's AI which product to pick, and a competitor gets named | There's a steady queue of work and a manager who knows search |
| Who does the writing | Often your team, from the agency's briefs | Varies; ask whether pages arrive finished | The hire |
| What gets reported | Rankings, traffic, links | AI answers by prompt and assistant, plus rankings | Whatever the hire sets up |
| Time to start | Weeks | Weeks | Months to recruit and ramp |
| Main risk | A roadmap nobody has time to carry out | Reports full of mention rates that never connect to signups | One person carrying everything; the knowledge leaves with them |
| If it ends | You keep the documents | Depends on whose accounts the data and tools live in | You keep the systems if they're documented |
What's the difference between an AEO agency and an SEO agency?
An SEO agency works to get your pages ranked in Google's list of results. An AEO (answer engine optimization) or GEO (generative engine optimization) agency works to get your company named inside the answers AI assistants write. In practice the jobs overlap: pages that open with a direct answer, state facts in text, keep prices consistent and use clean structure tend to do well in both. The real differences are in measurement and in off-site work. An AEO agency should track a fixed list of buyer questions across assistants, record who was picked and which sources were cited, and work on the review sites, directories and lists those assistants read. Justin's longer write-up on GEO vs SEO walks through what changes and what doesn't.
Questions to ask any agency before you sign
The first four come from Google's own list of questions to ask an SEO. The rest are the ones that matter for AI answers.
- Can you show me previous work and results for a company like ours?
- Do you follow Google Search Essentials?
- What results do you expect, in what timeframe, and how do you measure success?
- Will you share every change you make to our site?
- Which buyer questions will you track, in which assistants, and who picks the list?
- Do your reports show who the assistant recommended and which sources it cited, or only whether we were mentioned?
- How do you connect rankings and AI answers to signups or pipeline?
- Who writes the pages, who edits them, and can anything go live without our approval?
- Where do the data, prompts, dashboards and drafts live, and what do we keep if we stop?
- How do you keep prices and product facts the same on every page?
- Does your own site meet the page standard you'd hold ours to?
That last one is fair to ask. We run our own sites against the standard we sell. On a November 2, 2026 scan, justinmckelvey.com scored 93 out of 100, superdupr.com 89 and getlocalcall.com 87, and the gaps went on our own fix list.
Red flags that should end the conversation
| Red flag | Why it matters |
|---|---|
| Guaranteed rankings | Google: "If they guarantee you that their changes will give you first place in search results, find someone else." |
| Guaranteed AI citations ("we'll get you into ChatGPT") | Assistants decide on their own, and the same question can get a different answer tomorrow. An agency can improve your odds and measure them. It can't promise them. |
| Mention rate is the only AI metric | Being mentioned in a list of five isn't being picked. You need who was recommended, for which question, and whether those visits turned into signups. |
| Bulk AI-written content | Google's spam policy names "using generative AI tools or other similar tools to generate many pages without adding value for users" as scaled content abuse. |
| A "special relationship" with Google or an AI company | Google names a claimed "special relationship" with Google as a warning sign. A claimed inside line to an AI company deserves the same doubt. |
| Vague about the work | Google: "Be careful if a company is secretive or won't clearly explain what they intend to do." |
| Cold outreach promising page one | Google: "Be wary of SEO firms and web consultants or agencies that email you out of the blue." |
| Accounts and data in the agency's name | If the program ends, your history, prompts and dashboards go with them. |
Reporting is where weak agencies hide. Our page on automated SEO reporting covers what a useful monthly report contains, and the same test applies to AI answers: every number should lead to a decision.
When does an in-house hire make more sense?
When search is a core channel, the work queue never empties, and someone on the team can manage the hire and judge the output. A hire learns your product better than any agency will. The catch is time and coverage: recruiting takes months, one person rarely covers technical SEO, writing, analytics and AI tracking equally well, and when they leave, the knowledge often leaves too. Many teams land on a hybrid: an in-house owner who sets priorities and approves pages, with an outside team that drafts, ships and measures.
What should the first 90 days with an agency look like?
Ask for this shape in the proposal. A baseline of rankings, AI answers and signups in the first two weeks. A triage of existing pages (keep, refresh, merge, redirect or remove) before anything new is written. The pages closest to a buying decision, like comparison and alternatives pages, rebuilt first. Then new pages, with each one measured from the day it goes live. If the plan starts with 50 new blog posts, it's built around output, not results.
Price is the other half of the decision. Published AEO and GEO retainers run from about $3,000 to $15,000 a month on the rate cards we found, and our breakdown of what an AEO or GEO agency costs shows what each level includes.
Where SuperDupr fits
Full disclosure: we sell this work, so weigh our view accordingly. Our AEO agency work covers answer-shaped pages, prompt tracking and the off-site sources assistants read. Companies with a marketing team can have us run SEO, GEO and AEO together as an AI Search Program: we draft pages into your CMS or code for your team to approve, and report weekly on rankings, AI answers and signups. It's month to month and priced after a 30-minute call. Software companies should look at our B2B SaaS SEO agency page.

Frequently Asked Questions
-
Ask for previous work for companies like yours, how they measure success and in what timeframe, whether they follow Google Search Essentials, and whether they'll share every change they make. For AI search, also ask which buyer questions they track, whether reports show who the assistant recommended, how results tie to signups, and where your data lives if you stop.
-
An SEO agency works on rankings in Google's results. An AEO or GEO agency works on getting your company named in the answers AI assistants write. The work underneath overlaps a lot; Google says no special optimization is needed for its AI features beyond SEO fundamentals. The differences are prompt tracking across assistants and work on the off-site sources assistants cite.
-
No. AI assistants decide on their own, and the same question can get a different answer on a different day. An agency can improve your odds and measure them. Google says the same about rankings: no one can guarantee a #1 ranking.
-
Hire in-house when search is a core channel, the work never runs out, and someone can manage the hire. Use an agency when you need several skills at once, technical SEO, writing, analytics and AI tracking, without recruiting for months. Many teams pair an in-house owner who approves pages with an outside team that drafts, ships and measures.
-
Guaranteed rankings or AI citations, reports that only show mention rates, bulk AI-written pages (Google calls mass pages made without adding value scaled content abuse), claims of a special relationship with Google, vague answers about the work, and accounts or data held in the agency's name.
