AI SEO Agency vs GEO Agency vs SEO Agency: Which One You Actually Need

Agencies advertising themselves with the words AI and SEO are selling one of two different services, and the label will not tell you which. The first group uses AI tools to run classic search engine optimisation faster, while the second works to get your brand cited and recommended inside AI-generated answers, a discipline called generative engine optimization (GEO) that also travels as answer engine optimization (AEO). The two come with different deliverables, different metrics, and different proof of success. This piece separates the three offers you will meet when you go shopping, the AI-assisted SEO agency, the GEO agency, and the classic SEO agency, and matches each to the situation where it is the right buy.

I run GEO at Lore, and we sell all three motions under one roof, which removes my incentive to declare any of them obsolete and gives me a strong one to stop you buying the wrong thing first. The sorting question is simple: are you trying to improve where you rank in search results, or trying to change what AI engines say when a buyer asks about your category? The first is SEO work, with or without AI tooling behind it, and the second is GEO work. Most growing companies end up needing both, and the rest of this article is about which to buy first.

What is an AI SEO agency?

An AI SEO agency, in the most common use of the term, is a traditional SEO agency that uses AI tooling to speed up classic search work: keyword research, content drafting, technical auditing, internal linking, and reporting. The deliverable has not changed. You are still buying rankings, organic traffic, and the conversions that follow, measured in the same Search Console graphs as ever. What changed is the production line behind those deliverables.

Used well, that production line is a genuine advantage. Research that took a strategist a week now takes a day, and the saved hours go into the judgement work that machines are poor at: picking the queries worth winning and shaping a point of view. Used badly, it becomes the modern version of a very old playbook. I have tracked algorithm history since long before GEO existed, back to the doorway-site link farms and the Google updates that wiped them out, and the pattern repeats each cycle: unedited AI keyword dumping is today's equivalent, and it loses the same way. What gets sites penalised is valueless content, whoever or whatever wrote it. So when you evaluate an agency wearing the AI SEO badge, the question is where the humans sit in the process. If the answer is nowhere, you are buying volume that can damage your reputation with readers and engines at the same time.

One more caution from the buying side: some agencies adopted the AI SEO label as pure repositioning, with nothing underneath but the same service and a new homepage. The vetting section below covers how to tell.

What is a GEO agency?

A GEO agency works to get your brand named, cited, and recommended inside AI-generated answers from engines like ChatGPT, Perplexity, and Google's AI features. That is the one-sentence definition, and the discipline goes by two names depending on who you ask: generative engine optimization and answer engine optimization describe the same work from slightly different angles.

The deliverables look different from an SEO retainer. A GEO programme produces citation-ready content structured so retrieval systems can lift and attribute it, technical work that makes sure AI crawlers can access the site at all, third-party brand mentions that teach models what you do and who you serve, and monitoring that tracks how often the engines name you. Success is measured in share of voice inside AI answers rather than in blue-link positions. I have broken down the full deliverable list in what a GEO agency does, and the mechanics of the discipline itself in GEO vs SEO.

Why this became its own agency category: by the numbers we publish and plan against at Lore, organic search traffic is down roughly 30% across the board, while the traffic AI engines refer converts at 3 to 6x the rate of traditional organic. Fewer visits, each worth more, and a brand either shows up in the answer or it does not. One of our clients, BizScout, a business marketplace, built over 450 AI mentions across twelve months of this work, and ChatGPT now cites them as a go-to source for business buyers.

A finding from live client work that illustrates how young this discipline is: businesses regularly arrive on GEO plans with AI crawlers blocked by default in robots.txt. A cheap fix with a severe cost, and the kind of thing a classic SEO audit never looked for because it never had to.

What does a classic SEO agency still do?

A classic SEO agency improves your visibility in traditional search results through three arms of work: content that covers your buyers' pain points in depth, technical health so the site gets crawled and indexed properly, and backlinks plus brand mentions that give engines third-party proof you matter. Most businesses get the content arm roughly right on their own and ignore the other two, which is usually why DIY efforts stall.

This remains the right buy more often than the current conversation suggests. Search behaviour is audience-specific: age, education, and geography all change whether your buyer types a query into Google or asks an assistant, so the starting point is data about your audience rather than anyone's enthusiasm for a new acronym. And while competitors crowd the shiny new thing, the classic channel is a profitable market left unattended. Ambiance Creations, a kitchen and bath client of ours, went from 939 organic clicks to more than 31,000 in a year, a 33x lift, on work that any strong SEO practice would recognise. The same programme made them the AI answer for kitchen remodelling in their market, which previews the point the next two sections make.

Which agency you need, by situation

Match the engagement to the problem in front of you:

• ChatGPT recommends your competitors and skips you. GEO work, directly. Start by measuring the gap; an AI visibility audit tells you which engines mention you, for which questions, before you commit to a retainer.
• Organic traffic has been sliding since AI Overviews arrived. Usually both motions, sequenced. You need to know whether buyers left the channel or just stopped clicking, and that diagnosis decides whether the budget goes to winning the AI answer, defending rankings, or both.
• You rank nowhere yet and your audience still searches Google. Classic SEO first, built citation-ready from day one so every page also works as GEO material later. Starting with GEO on a site with no technical foundation skips the step everything else stands on.
• You already have an SEO agency you like. Ask them what they are doing about generative engines, specifically what they monitor and what they would change on your site. The questions to ask a GEO agency work just as well on an incumbent.
• Budget for exactly one engagement. Pull real query and referral data before deciding. My opinion does not settle this and neither does yours; where your buyers ask their questions settles it, and that split differs by audience. If you are weighing the agency route against doing it in-house, I have compared both paths in GEO agency vs DIY.

Where the three offers overlap

The GEO-versus-SEO framing suggests a fork in the road, and I refuse it every time a client brings it to me. AI visibility matters and keeps growing, but traditional search has not gone away, and done correctly one action serves both surfaces. Clean technical foundations feed Googlebot and AI crawlers alike. Deep pain-point content earns rankings while giving retrieval systems citation-ready passages to lift. Third-party mentions function as link equity in classic search and as the trust signals that decide which brands models cite, because every business claims to be the best, and the engines believe the third parties instead. I have mapped the full relationship in GEO vs SEO.

Tides Mental Health shows the overlap in one engagement: 4.7x organic traffic growth in five months, page two to page one on their core terms, and AI engines recommending them for anxiety treatment, all from a single integrated programme. Ross Simmonds makes a version of the same argument in his breakdown of how the two disciplines relate, worth fifteen minutes if you are deciding where to put budget:

The practical consequence for a buyer: a GEO-only shop with no SEO depth will struggle with the technical and link arms its own discipline depends on, and an SEO shop that ignores generative engines is leaving the fastest-growing answer surface to your competitors. The strongest buy is usually a team that treats them as one expanded search channel.

How to vet whichever agency you choose

Four checks expose most weak offers, whatever the label on the homepage:

• Ask what data they plan from. The answer should be your Search Console and analytics, because once GSC is connected it outweighs every third-party tool, especially for newer sites. An agency that builds strategy from a founder's intuition about the value proposition is guessing on your budget.
• Ask what number they report and what it answers to. Rankings, share of voice in AI answers, or revenue-adjacent conversions. Every channel needs a metric it is accountable to, and vague visibility talk with no mechanism behind it is the tell of a repositioned homepage.
• Ask where humans edit. For anything badged AI, this question separates a production advantage from a content farm.
• Ask how they handle links and mentions. Purely earned links arrive too slowly to promise to an unknown brand, so a credible agency builds paid press distribution into the standard package and says so. A promised count of earned-only links is a promise someone eventually breaks.

Frequently asked questions

What is an AI SEO agency?

An AI SEO agency is either a traditional SEO agency that uses AI tools to produce classic search results faster, or an agency that optimises your brand to be cited inside AI-generated answers, which is properly called a GEO or AEO agency. The label is used both ways in the market, so check the deliverables: rankings and organic traffic mean the first, citations and share of voice in AI answers mean the second.

Is there an AI that can do SEO?

AI tools handle real parts of the job, including research at scale, drafting, and technical crawling, and using ChatGPT or Claude as a sounding board for strategy is legitimate. What no tool supplies on its own is connected search data and the judgement about what your specific audience searches and why. Fully automated SEO also carries algorithm-change risk: tactics that hack the system get wiped by updates, and unedited AI output published at volume is the current version of that trap. The craft sits in the people running the tools.

How much does an AI SEO or GEO agency cost?

Monthly retainers vary widely with scope, because the work spans content production, technical fixes, and third-party mention building, and each arm scales with how competitive your category is. A sensible way in without committing to a retainer: Lore's Visibility Audit is $497 one time, delivered within 48 hours, and it shows where you stand in both classic search and AI answers before you spend more. I have broken the pricing question down fully in how much GEO costs.

Do I need a GEO agency and an SEO agency at the same time?

Usually you need both disciplines but one team. The foundations overlap heavily, since the technical, content, and mention work that earns rankings also feeds AI citations, so splitting the channel across two agencies creates coordination cost without adding capability. Sequence by where your buyers are: if AI engines already answer your category's questions and you are absent, start there; if your audience still lives in classic search, build that first and keep every page citation-ready.
