Most businesses in 2026 still need an SEO agency first and an AEO agency second, because AI engines like ChatGPT, Perplexity, and Google AI Overviews overwhelmingly cite pages that already carry search authority. The budgets differ too: Clutch pegs the average SEO retainer at $3,199 per month, while typical AEO retainers run $2,000 to $10,000 per month across published 2026 pricing guides. If nobody can find you on Google, an AEO retainer is interior decorating for a house with no plumbing.
The uncomfortable part is that the ground is moving under both agency types at once. Semrush tracked AI Overviews on 15.69 percent of US desktop queries in November 2025 after a peak near 25 percent that July. SparkToro and Datos report that 60 percent of Google searches now end without a click to any website. Ahrefs measured a 58 percent drop in position one clickthrough when an AI Overview sits above the results. So “just keep doing SEO” is also the wrong answer. Below is what each agency type actually ships, what each costs, and a plain decision rule for which one to hire.
What does an SEO agency actually do in 2026?
An SEO agency gets your pages ranked in Google’s classic organic results and turns those rankings into clicks and leads. The core work is keyword research, technical fixes, on page optimization, content production, and link acquisition, all measured through Google Search Console.
A typical engagement runs like this:
- Weeks 1 to 4: technical audit covering crawl errors, site speed, and indexation, usually run through Screaming Frog, Semrush, or Ahrefs, plus a keyword map tied to your money pages.
- Weeks 4 to 12: on page rewrites, title tag and internal link cleanup, the first content batch, and Google Business Profile work for local firms.
- Month 3 onward: ongoing content, link building, and monthly reports on rankings, clicks, and conversions.
Timelines are the honest tell. Credible agencies quote four to six months before rankings move in a meaningful way, and agency survey data from SE Ranking backs that range. Anyone promising page one in 30 days is selling something other than SEO.
Before you sign either kind of retainer, find out what Google and the AI engines already say about your business. Run a free AI visibility audit so you walk into agency calls with data instead of their pitch deck.
What does an AEO agency actually do?
An AEO agency gets your brand cited and recommended inside AI generated answers on ChatGPT, Perplexity, Gemini, Claude, and Google AI Mode. Instead of chasing rankings for keywords, it chases citations for prompts, meaning the questions real buyers type into assistants. If the discipline is new to you, start with what answer engine optimization is.
The deliverables that separate real AEO shops from rebranded SEO shops:
- Prompt research: a documented list of 50 to 200 buyer prompts, with a baseline showing who gets cited on each one today.
- Citation tracking reports: monthly visibility by engine, pulled from platforms like Profound, Otterly, or Peec AI, plus the AI Performance data inside Bing Webmaster Tools.
- Schema buildout: Organization, Service, FAQPage, and review markup so engines can parse who you are, what you do, and why you are credible.
- Entity cleanup: fixing the contradictory names, addresses, and descriptions scattered across directories and data sources that AI models train on and retrieve from.
- Answer shaped content: pages structured so an engine can lift a self contained answer, loaded with the statistics and named sources models prefer to cite.
- Third party visibility: mentions and reviews on the publications, forums, and comparison sites each engine retrieves from, because engines cite sources, not just brands.
The channel is smaller than classic search, but it converts. Search Engine Land’s analysis of 6.77 million AI referral sessions found ChatGPT driving 92 percent of trackable LLM referral traffic, and 2025 to 2026 studies from Rocket Agency and ALM Corp measured AI referral visitors converting anywhere from 1.3 times to 5 times better than organic visitors, because a visitor arriving from a recommendation is already pre sold.
How do the deliverables compare side by side?
The overlap is real, roughly the technical and content foundations, but the measurement and off site targets are different jobs. Here is the honest comparison:
| Function | SEO agency | AEO agency |
|---|---|---|
| Primary goal | Rankings and clicks in Google | Citations and recommendations in AI answers |
| Unit tracked | Keywords | Buyer prompts |
| Technical work | Crawlability, speed, indexation | Schema buildout, AI crawler access (GPTBot, PerplexityBot) |
| Content | Keyword targeted pages | Extractable answers with stats and named sources |
| Off site work | Backlinks | Mentions and reviews on sources engines retrieve from |
| Reporting stack | Google Search Console, Semrush, Ahrefs | Profound, Otterly, or Peec AI, Bing Webmaster Tools AI Performance, GSC |
| First results | 4 to 6 months | 6 to 12 weeks for citation movement |
Two things matter in that table. First, both disciplines depend on a clean site and strong content, which is why the foundations transfer. Second, an agency that reports only in Google Search Console and Semrush keyword positions is not doing AEO, no matter what the invoice says.
What do SEO and AEO agencies cost per month?
SEO retainers for small and midsize businesses run $1,500 to $5,000 per month, with Clutch’s marketplace average at $3,199 and Backlinko’s practitioner survey finding $1,000 to $2,500 the most common band. AEO retainers for the same tier run $2,000 to $10,000 per month.
SEO pricing in 2026:
- Freelancers and small shops: $500 to $1,500 per month, usually thin scope
- Serious SMB retainers: $1,500 to $5,000 per month, with WebFX benchmarking most businesses at $2,500 to $7,500
- Enterprise programs: $10,000 to $30,000 and up
AEO pricing in 2026:
- One time audits: $1,500 to $5,000
- SMB retainers: $2,000 to $5,000 per month
- Mid market retainers: $5,000 to $10,000 per month, where pricing guides from Digital Elevator and Stackmatix converge
- Enterprise programs: $10,000 to $30,000 and up
Do not confuse agency fees with tool fees. Tracking platforms are cheap by comparison: Otterly starts at $29 per month, Peec AI runs roughly $100 to $220, and Profound starts around $499. The tools measure visibility; they do not create it. The retainer pays for the schema, content, entity, and PR work that moves the numbers. For a deeper teardown of what drives the price up or down, see how much GEO costs.
When do you need an SEO agency and when do you need an AEO agency?
Budget and current visibility decide this, not trend articles. If you rank for nothing and have under $2,500 a month, hire SEO. If you already rank and sell high value services, AEO is where the next dollar works hardest.
Hire an SEO agency first if: your site is new or barely indexed, you rank for almost none of your money keywords, or your customers still click through to compare options (home services, ecommerce, local emergencies). AI engines cite established sources; SEO is how you become one.
Hire an AEO agency first if: you already hold page one positions, competitors are showing up in ChatGPT and Perplexity answers while you are absent, or one client is worth five or six figures. For lawyers, surgeons, and B2B software, a single AI recommendation can pay for the entire quarter’s retainer, which is exactly why AI referral conversion runs multiples above organic in the Rocket Agency data.
Run both if: you can fund $3,000 or more per month and your revenue depends on being the recommended name rather than one of ten blue links. This is where the market is heading, and splitting the work across two uncoordinated vendors is usually worse than either alone.
Should one agency handle both SEO and AEO?
Usually yes, if the budget allows, because roughly 70 percent of the underlying work overlaps and two vendors will fight over the same pages. One rewrites a page for keywords, the other restructures it for extraction, and the schema conflicts pile up while you referee.
The caveat: a combined engagement only makes sense when the agency can show separate proof for each discipline, meaning ranking reports from Google Search Console and Semrush on the SEO side, and citation tracking reports from Profound, Otterly, or Bing Webmaster Tools on the AEO side. A shop that added AEO to its homepage last quarter but still ships only keyword dashboards is an SEO agency with new labels. Before you take calls, compare each proposal against a real combined scope of services so you know what a full engagement should include. And if you are weighing an agency against hiring internally, read the honest breakdown of GEO in house vs agency first.

What else do buyers ask about SEO and AEO agencies?
Is AEO just SEO with a new name?
No. The foundations overlap, but AEO measures citations across ChatGPT, Perplexity, and Gemini rather than keyword rankings, and its off site work targets the review sites, forums, and publications engines retrieve from rather than backlink metrics. An agency doing real AEO can show you a prompt list and a citation report. An agency doing renamed SEO can only show you rankings.
Can my current SEO agency just add AEO?
Sometimes, but make them prove it. Ask for a sample citation tracking report, ask which platform they use (Profound, Otterly, Peec AI, or a documented in house pipeline), and ask to see Bing Webmaster Tools AI Performance data from a current client. If the answer is a slide about “AI readiness” with no data behind it, they are learning on your budget.
How fast does AEO show results compared to SEO?
Faster, usually. Retrieval based engines like Perplexity and ChatGPT search pull from the live web, so schema fixes, entity cleanup, and new citations can surface in answers within 6 to 12 weeks. Classic SEO needs four to six months because Google’s ranking systems reward accumulated authority. Timelines stretch for competitive categories in both disciplines.
Do I still need SEO if AI answers everything?
Yes. SparkToro and Datos put zero click searches at 60 percent, which still leaves billions of clicks on the table, and Semrush data shows AI Overviews on roughly 16 to 25 percent of queries, not all of them. More important, AI engines cite pages that rank well and get referenced often. Strong SEO is the raw material AEO works with.
What is the difference between AEO and GEO?
They describe the same discipline: earning visibility inside AI generated answers. AEO (answer engine optimization) and GEO (generative engine optimization) are competing labels, and some agencies also say AI visibility or LLM SEO. When comparing proposals, ignore the acronym and compare the deliverables: prompt research, citation tracking, schema, entity work, and third party mentions.
How much should I budget for SEO and AEO together?
Plan on $3,000 to $8,000 per month for a serious combined program at the SMB and mid market level, based on Clutch’s SEO averages plus the AEO ranges published by Digital Elevator and Stackmatix. Under $2,500, run SEO with AEO friendly content structure and revisit dedicated AEO once rankings exist.
The clean way to think about it: SEO earns the authority, AEO converts that authority into recommendations, and in 2026 the buyers worth the most are increasingly asking an assistant instead of scrolling a results page. Pick the agency that fixes your weakest link. If Google barely knows you exist, that is SEO. If Google knows you but ChatGPT recommends your competitor, that is AEO, and every month you wait, the models get more confident in someone else’s name.
