Best SEO and AEO agencies for businesses in 2027

There is no single best SEO and AEO agency, and a list that names one is selling something. This page lists ten agencies that publicly sell both search engine optimization and AI search work, sorted by the kind of business each says it serves. ElytraCo publishes this list and sells these services, so it is included below and labeled as ours.

Read it with that in mind. We did not rank anyone, we did not put ourselves first, and every fact about another agency comes from that agency's own website, linked so you can check it. Where a site did not state something, we left it out. If you run marketing for a multi-location brand, our enterprise page explains how we work, and SEO vs AEO covers how the two services differ.

How was this list put together?

We started from 14 agencies that are often named for SEO, AEO or GEO (generative engine optimization) work and opened each one's website on 14 November 2026. An agency stayed on the list if its own site listed both an SEO service and an AI search service, and published enough about who it serves to describe it without guessing.

• Nobody paid to be listed. No agency asked to be included or saw this page before it went up.
• This is not a quality ranking. We have no audited data on any agency's results, including our own. The order follows the type of client, and within a group it is alphabetical.
• Only their own words. Services, client type, location and price come from each agency's site. We added no opinions and no comparisons of quality.
• Leaving an agency out says nothing about it. Ten is where we stopped. Many capable agencies are not here.

Which agencies offer both SEO and AEO?

All ten below list both on their own sites. The table sorts them by the business each one says it serves. "None published" means we found no price on the pages we read, not that the agency is expensive or cheap.

Agencies for enterprise, growth and B2B brands

iPullRank. iPullRank describes itself as an enterprise and mid-market AI search agency. Its services menu lists generative engine optimization, technical SEO, content marketing, content engineering and an approach it calls relevance engineering. Its contact form asks whether your brand is emerging, growth or elite. We found no pricing on the pages we read.

NoGood. NoGood is a growth marketing agency that lists AEO and SEO beside paid search, paid social, conversion rate optimization and analytics. It says it works with startups, scaleups and Fortune 100 brands, and that it is headquartered in New York City with offices in Miami and Dubai. Its site says engagements are monthly retainers and that its average retainer is above $20,000 a month.

Omniscient Digital. Omniscient Digital calls itself an organic growth agency for B2B software businesses. Its services include SEO strategy, answer engine optimization, digital PR, programmatic SEO, technical SEO and content production. The site lists an Austin, Texas address and states that full-service engagements start at $120,000 a year.

WebFX. WebFX says it works with businesses of all sizes and lists offices in Harrisburg, Tampa, Houston, San Francisco and Ann Arbor. It sells SEO and GEO as separate services and publishes a starting price for each: SEO services from $2,900 a month on its SEO pricing page, and GEO from $3,000 a month on its GEO services page.

Agencies for law firms

Hennessey Digital. Hennessey Digital says it works with other industries too, but that legal is its deepest bench. It lists law firm SEO and law firm GEO as separate services, with web development, paid search and digital PR, and gives a main office in North Hollywood, California. It publishes no rate card. Its FAQ says entry-level law firm SEO programs often begin in the low-to-mid five figures a month.

Rankings.io. Rankings.io works with law firms and calls personal injury its specialty. It also lists criminal defense, family, immigration, employment and bankruptcy practices. Its services include SEO, AI search (which it labels AIO), Local Services Ads, Google search ads, paid social and website design. We found no pricing on its site. It offers a complimentary growth audit.

Agencies for medical practices

Etna Interactive. Etna Interactive describes itself as a full-service medical marketing agency, with pages for plastic surgery, facial plastic surgery, medical spa, dermatology and ophthalmology marketing. It lists search engine optimization and answer engine optimization as separate services. Its site says it is fully remote and serves healthcare clients nationwide. It publishes no pricing.

Rosemont Media. Rosemont Media is a healthcare agency in San Diego with a stated emphasis on plastic surgery and dental practices. It lists SEO and generative engine optimization, each with its own pages for plastic surgeons and dentists, along with custom website design. Its site says it works with one practice per market. It publishes no pricing.

Agencies for home service companies

Hook Agency. Hook Agency serves home service contractors and names roofing, HVAC and plumbing. It sells local SEO and AEO as one package at a published $3,750 a month, with Google Ads, Local Services Ads, Meta ads and websites priced separately. Its FAQ says its services fit companies with $3M to $15M in revenue.

Law, medical and home services from one provider: ElytraCo

ElytraCo (the publisher of this list). ElytraCo works with law firms, medical practices and home service companies, and scopes custom programs for multi-location brands. It sells AEO and offers traditional SEO alongside it. ElytraCo's AEO plans run from $2,500 to $10,000 or more a month, and enterprise programs are custom scoped (see AEO pricing).

What do the published prices tell you?

Less than you would hope, because they price different things. WebFX's $2,900 a month is a starting SEO package. Hook Agency's $3,750 a month covers local SEO and AEO together for one contractor. NoGood's average above $20,000 a month covers a growth team that also runs paid media. Omniscient Digital's $120,000 a year is a full-service floor for B2B software companies.

So compare scope before price. Put each proposal's deliverables side by side, and strike anything that appears in both an SEO and an AEO line, since technical fixes, structured data and core service pages should be billed once. Our AEO vs SEO cost comparison walks through that overlap with sourced market ranges.

What should you ask any of them before you sign?

Start with Google's list. Its "Do you need an SEO?" page suggests asking for examples of previous work, what results to expect and in what timeframe, how success is measured, and what experience the agency has in your industry and market. It also says no one can guarantee a first-place ranking on Google. That applies to AI answers as well, and to us.

Then ask whether you need a second agency at all. Google's guide to generative AI features says that, from its perspective, optimizing for AI search is still SEO, and it points buyers of third-party AEO or GEO services to its guidance on evaluating SEO advice. If your current SEO agency is doing sound work and can answer the questions below, keeping it is often the right call. A good SEO program is what gets your pages indexed, fast and eligible to be cited on Google in the first place.

1. Which engines do you test, and how often? Ask for the list (ChatGPT, Perplexity, Google AI Overviews and AI Mode, Gemini, Copilot, Claude) and the schedule.
2. How do you measure visibility? AI answers change on every run, so the honest unit is the share of repeated answers that name you, not a rank. Our share-of-voice guide covers the sample sizes.
3. What is billed once? Ask which technical, schema and content work is shared between the SEO and AEO scopes.
4. Who fixes the sources? Listings, directories, reviews and third-party mentions sit outside your website. Ask who owns each one, per location.
5. What will you not promise? An agency that guarantees a ranking or a place in an AI answer is promising something no engine offers.
6. What are the terms? Contract length, notice period, and who owns the content, accounts and data if you leave.

How to check where you stand

Before you call anyone on this list, run your own test. Write five questions a buyer would ask before choosing a business like yours, and ask each one three times in ChatGPT, Perplexity and Google's AI Mode. Note who is named, how you are described and which sources are cited. Take that record to every agency you interview, including your current one, and ask what they would change first. If you want a second read, our free AI visibility audit runs your real buyer questions across five engines and shows who is named and why.
