If your site has fewer than about 30 pages of real, answer-shaped content, you need a content agency first, because an AEO agency has nothing to optimize; if you already publish every week and ChatGPT, Perplexity, and Google AI Mode still never name you, you need an AEO agency, because a content agency alone will not get you cited in 2026. A content retainer from a firm like Animalz or Siege Media starts at $8,000 to $10,000 a month, a focused AEO retainer runs $3,000 to $8,000 a month per Digital Elevator’s 2026 pricing guide, and Muck Rack’s analysis of 25 million AI citations found that 84% of what ChatGPT, Claude, and Gemini cite is earned third party media, not the brand’s own blog. That last number is the whole argument: the content agency builds what AI engines read, and the AEO agency builds the reasons they trust it.
What does a content agency actually deliver, and what does an AEO agency deliver?
A content agency sells published words on your domain: strategy, briefs, drafts, edits, and a calendar. An AEO agency sells your name inside AI answers: prompt tracking, schema, entity cleanup, page restructuring, and third party mentions. The two overlap on maybe 20% of the work.
1. The content agency scope
Firms like Animalz, Siege Media, Omniscient Digital, and Grow and Convert deliver an editorial machine: topic research, a monthly calendar, 4 to 12 long form articles, on page SEO, design assets, and a report tied to organic sessions and conversions. Per Column Five’s 2026 pricing breakdown, blog posts run $150 to $600 each and long form guides $500 to $2,500, which is why a retainer producing eight strong pieces a month lands at $5,000 to $10,000 before strategy fees. What a content agency almost never delivers: tracking of how often Perplexity or Google AI Overviews cite those pages, FAQ and Speakable schema at the template level, cleanup of your Wikidata, Crunchbase, or Google Business Profile entity data, or placements in the outside publications AI engines pull from.
2. The AEO agency scope
An AEO agency starts with a prompt audit: 50 to 500 buyer prompts run across ChatGPT, Perplexity, Claude, Gemini, and Google AI Mode, usually inside Profound, Peec AI, Otterly, or Scrunch. From there the work is restructuring pages so the first 40 words answer the query, deploying schema, fixing entity inconsistencies across directories, building comparison and FAQ content, and earning mentions in the third party sources that show up in the citation logs. Per Digital Elevator’s 2026 guide, a retainer bundling optimization with 4 to 6 new AEO shaped posts a month runs $2,500 to $5,000, and a standalone audit runs $1,500 to $5,000. What an AEO agency almost never delivers: a 3,000 word thought leadership piece with original interviews, or 12 articles a month.

What do content agencies and AEO agencies cost side by side in 2026?
A content agency costs more per month and produces more artifacts; an AEO agency costs less and produces fewer artifacts with narrower intent. Neither is cheap once you add the tool stack.
Tier 1. Software only ($29 to $495 a month)
Otterly publishes plans at $29, $189, and $489 a month for 15, 100, and 400 tracked prompts. Peec AI runs $95 to $495 a month. Profound’s entry plan is $99 a month billed yearly for one seat and ChatGPT only; its enterprise contracts are quote based, often $30,000 to $100,000 a year. Scrunch starts at $250 a month and was acquired by Sitecore in June 2026. Tools measure. They do not write, fix schema, or earn a mention in a trade publication.
Tier 2. AEO agency retainer ($2,500 to $15,000 a month)
Per Digital Elevator’s 2026 guide and Gigawatt Group’s survey of published agency rates, growth stage companies land at $3,000 to $8,000 a month, B2B firms pay $2,000 to $10,000, and enterprise scopes covering 100 plus pages with weekly citation audits run $5,000 to $10,000 and up, plus a setup fee.
Tier 3. Content agency retainer ($2,000 to $30,000 a month)
Pitchsite’s 2026 content pricing guide puts most U.S. content retainers at $1,500 to $10,000 a month, averaging $3,200 to $3,500. The named SaaS shops sit higher: Animalz starts around $8,000 a month per Discovered Labs’ 2026 pricing analysis, Siege Media around $10,000, and Omniscient Digital around $11,000, with research heavy programs reaching $30,000 or more.
Tier 4. Both, or a combined program ($6,000 to $20,000 a month)
Stacking a $3,500 content retainer on a $3,500 AEO retainer gets you to $7,000 a month and two vendors who blame each other when a page ranks but never gets cited. Combined content, AEO, and press programs typically start around $5,000 to $6,000 a month.
Which of the four scenarios are you in?
Most businesses reading this fall into scenario 1 or 2, and only scenario 3 is a clean case for an AEO agency alone. Decide which one describes you before you take a sales call.
Scenario 1. Thin site, under $1M revenue: neither, yet
If you have a homepage, five service pages, and nine blog posts from 2023, no agency of either type is the right spend. A $189 Otterly plan plus one in house writer producing two answer shaped pages a week will outperform a $5,000 retainer that spends its first 90 days building what your writer can build. Revisit at 30 to 50 substantive pages.
Scenario 2. Thin site, real budget: content agency first, with AEO rules baked in
If you can fund $5,000 or more a month and have almost nothing published, hire the content agency, but write AEO requirements into the brief: question format headings, a direct answer in the first 40 words, FAQ schema on every article, and a monthly prompt check in Peec AI or Otterly. Grow and Convert and Omniscient Digital will both work to that brief. Plan on 6 months before an AEO agency has material to move.
Scenario 3. Deep library, zero AI citations: AEO agency
If you publish weekly, rank on page one for your core terms, and still never appear when someone asks ChatGPT or Perplexity for a recommendation, you are the textbook AEO client. The problem is not volume. It is structure, entity data, and missing third party corroboration. Vetting criteria: how to vet an AEO agency.
Scenario 4. Competitive category, high ticket service: both, under one roof
Law firms, cosmetic surgery practices, and B2B SaaS in crowded categories need production and citation work in parallel, because AI engines here lean on Avvo, RealSelf, G2, and press coverage more than on the brand’s own pages. One vendor accountable for both closes the rank-but-never-cited gap. How this differs from a traditional SEO hire: AEO agency vs SEO agency.
Where do the two overlap, and where does neither one reach?
The overlap is on page writing: both produce articles, and a good content agency in 2026 already writes in the question and answer shape AEO requires. The gap neither closes alone is the 84%.
Muck Rack’s three study editions since July 2025 put earned media at 82% to 89% of all AI citations, with paid and advertorial content at 0.3%. 5W PR’s analysis of more than one million prompts lands at 85.5%. AirOps’ 2026 State of AI Search report found roughly 85% of brand mentions in AI answers originate from external domains. The conclusion is uncomfortable for both agency types: most of the citation opportunity lives on domains neither one controls.
A content agency writes for your domain. An AEO agency optimizes your domain and tracks what happens off it, but most have no media relations arm that can land a mention in Above the Law, ABA Journal, or Women’s World. Ask how many third party placements the agency earned last quarter. If the answer is “we recommend PR,” you are buying 16% of the problem.
How fast should you expect results from each?
AEO structural changes show up in weeks; content agency results show up in quarters; third party trust signals land in between and decay fastest. Anyone quoting a single timeline is guessing.
1. AEO structural fixes: 2 to 45 days
Per a 2026 AuthorityTech analysis of citation refresh rates, FAQ schema and opening paragraph rewrites appear in Perplexity within 2 to 7 days, in ChatGPT within 7 to 21 days, and in Claude and Google AI Overviews within 14 to 45 days. Be suspicious of an AEO agency that cannot show anything by day 60.
2. Third party and review signals: 30 to 90 days
The same analysis puts review site presence and listicle inclusion at 30 to 90 days for model ingest. Trade press placements follow a similar window, so press work has to start in month one, not month six.
3. Content agency compounding: 3 to 9 months
Organic content typically needs 90 days to index and gather links and 6 to 9 months to compound. This is why an AEO agency hired onto a thin site stalls.
4. Decay: 4.5 weeks
The number nobody puts in the proposal: the same study measured 3.5 million citation events from September 2025 to March 2026 and found a median citation half life of 4.5 weeks, with ChatGPT churning fastest at 3.4 weeks and Perplexity holding longest at 5.8 weeks. Citations are refreshed monthly, not won once.
That half life is why we run AEO work and press work in the same monthly cycle at Subscribe PR; the tiers and what each includes are on our services page.
What questions should you ask each agency before signing?
Ask a content agency how its articles get cited, and ask an AEO agency what it does when there is nothing to optimize. The answers separate practitioners from resellers.
Questions for the content agency
- Show me three client articles cited by ChatGPT or Perplexity in the last 30 days, with the prompt.
- Do you deploy FAQ, Article, and Speakable schema by default, or is that an add on?
- Do you track AI citations in Peec AI, Otterly, Profound, or anything at all?
Questions for the AEO agency
- What do you do in months one through three for a client with 12 pages of content?
- How many third party placements did your last five clients earn, and where?
- What is your setup fee, and what does month four look like versus month one? (Benchmarks are in what a fair AEO agency setup fee looks like.)
Frequently asked questions
Is an AEO agency just a content agency with new branding?
Sometimes, and it is worth checking. Per Gigawatt Group’s 2026 review of published agency rates, a real AEO engagement includes prompt tracking across ChatGPT, Perplexity, and Google AI Mode, schema deployment, entity data cleanup, and third party mention work. If the proposal reads like 8 blog posts a month with a new label, that is a content agency, and you should pay $150 to $600 per post rather than a $5,000 AEO retainer.
Can a content agency get me cited in ChatGPT without an AEO agency?
Occasionally, for informational prompts where your own article is the best available answer. For recommendation prompts (“best employment lawyer in Charlotte,” “top rhinoplasty surgeon in Dallas”) it is unlikely, because Muck Rack’s 2026 data puts 84% of AI citations on third party earned media. Animalz and Grow and Convert produce cite-worthy pages, but no blog alone earns the corroboration those prompts require.
How much should a small law firm or surgical practice budget for this in 2026?
A practice with a thin site should budget $189 to $495 a month for Otterly or Peec AI plus writing capacity, not an agency. Once it has 30 to 50 real pages and $3,000 to $6,000 a month to commit, a combined AEO and press program becomes the efficient buy, per the 2026 ranges from Digital Elevator and Pitchsite. Advertising rules such as ABA Model Rule 7.1 still govern every claim in every article, whichever vendor writes it.
Do I need Profound if I hire an AEO agency?
No. A competent AEO agency runs its own tracking on Peec AI, Otterly, or Profound seats already. Profound’s $99 a month entry plan is ChatGPT only; its enterprise tier runs $30,000 to $100,000 a year and suits in house teams at large brands, not a firm paying an agency $4,000 a month. Ask which tool the agency uses and request read access to your prompt set.
What happens to my citations if I stop paying either agency?
They decay. The 2026 AuthorityTech study measured a median AI citation half life of 4.5 weeks across 3.5 million events, with ChatGPT dropping citations in 3.4 weeks on average. Content on your own domain keeps ranking in Google for months after you stop publishing; AI citations refresh far faster and depend on continuing third party mentions. Plan for an ongoing owner.
The takeaway
The question is not which agency is better. It is which half of the citation problem you have not solved. A thin site needs a content engine (agency, freelancer, or in house) before an AEO agency can do anything with it. A deep library that AI engines ignore needs structure, entity data, and third party trust, which is AEO work. A high ticket service business in a crowded category needs both on the same monthly clock, because Muck Rack’s 84% earned media figure and the 4.5 week citation half life mean the work is never finished, only refreshed. Pick the scenario, then buy the scope that fits it. Not sure which scenario you are in? Run the free AI visibility audit and see exactly which prompts cite you, which cite a competitor, and what the gap is made of.
