Top Digital Marketing Agencies for AI Search, Ranked (2026)

The top digital marketing agency for AI search, if you run an e-commerce or Shopify brand, is QCK: it handles AI search, SEO and conversion testing for online stores under one roof, and publishes the record to back it up, including 197 A/B tests and 7,960 live pages built for clients. Below, seven more agencies whose own websites describe a dedicated AI search, GEO or AEO service are ranked by how well they fit online stores.

Disclosure: QCK wrote this list. We put ourselves first, and the rest of the list is ranked by how well each agency fits e-commerce and Shopify brands. Every description of another agency comes only from its own website or a named public source.

This guide is for e-commerce and Shopify brands deciding whether to hire for AI search and who to hire. You'll get the data on why AI search matters for stores, what the work involves, an evaluation framework you can use on any agency (including us), the ranked list with a factual profile of each agency, and the questions that separate a real AI search program from a rebranded SEO retainer.

Why brands now hire for AI search

Two shifts make AI search worth paying attention to. First, AI summaries change how people click. Pew Research Center analyzed the browsing of 900 US adults in March 2025. In 18% of the Google searches it studied, an AI summary appeared. When one did, users clicked a traditional search result in 8% of visits, compared with 15% when no summary appeared. A link inside the AI summary itself was clicked in about 1% of visits.

Second, shoppers are using AI tools to find products. Adobe Analytics reported that during the 2025 holiday season (November 1 to December 31), traffic to US retail sites from generative AI tools, meaning shoppers clicking a link to a retail site, rose 693.4% compared with the year before. On Cyber Monday alone, AI traffic to US retail sites rose 670%. These are growth rates, not shares of total traffic, so they show direction more than size.

Put together, the picture for a store is clear: fewer clicks go to the classic blue links when an AI answer appears, and a fast-growing slice of shoppers starts in an AI tool. Being the brand the answer names, and the link it cites, is now part of organic growth. For the difference between the disciplines, see our guide to SEO vs GEO.

What an AI search agency actually does

Labels vary. You'll see GEO (generative engine optimization), AEO (answer engine optimization), LLM optimization and AI SEO. Underneath the labels, a credible program covers the same five areas.

• Measurement. Tracking a defined set of prompts across AI platforms, recording when your brand is mentioned and cited, which competitors appear instead and which sources the answers rely on.
• Technical access. Making sure AI crawlers can reach your pages (robots.txt rules for bots such as OAI-SearchBot and PerplexityBot), that key content renders without heavy JavaScript, and that structured data describes your products and organization.
• Content built to be cited. Clear answers near the top of pages, comparison and buying guides, product pages with specific facts, and FAQ content that matches how shoppers phrase questions.
• Entity and earned signals. Consistent brand facts across the web, plus press, reviews, community discussion and retailer pages that AI answers draw from. Our guide to knowledge graph optimization covers the entity side.
• Conversion. AI-referred visitors still need a page that answers their question and makes buying easy. An AI search program that stops at the click leaves money on the table.

You can test the technical basics yourself before you talk to anyone. Run your robots.txt through the free robots.txt tester, check key pages with the AEO checker, and read how to check if ChatGPT can crawl your website.

How to choose an AI search agency

Before you read the ranked list, decide what you're judging. Agency websites all sound similar, so judge them on what they can show you. Score each shortlisted agency from 1 to 5 on the criteria below, based on what they show in the sales process, not what they promise.

Google's own advice on hiring an SEO applies here too. Its Search Central guide suggests asking for examples of past work, what results to expect and over what timeframe, how success is measured, and what experience the agency has in your industry. It also lists red flags, including guarantees of top rankings, claims of a special relationship with Google and secrecy about methods.

How we ranked this list

Earlier versions of this page used scores and testimonials we couldn't verify, then an unranked alphabetical list. This version is ranked, using rules you can check.

1. Dedicated service. Each agency's own website, checked in October 2026, names a specific AI search, GEO or AEO service, not just a mention of AI in a blog post.
2. Organic search core. Each agency offers SEO or content alongside its AI search work, since AI visibility depends on the same foundations.
3. Ranked by fit for online stores. QCK is first: we wrote the list, and e-commerce and Shopify brands are our focus. The others are ordered by how much e-commerce, marketplace and conversion work their own sites describe.
4. Facts only from public sources. Every description of another agency comes from its own website or, where stated, a named public source such as a press release. We included no client results, pricing, ratings or awards for any other agency, because we couldn't verify them independently. QCK's entry uses only figures already published on qck.co.

Many capable agencies didn't make this list simply because their sites lead with paid media, social or web design rather than a named AI search service. That says nothing about their quality, only about the scope of this page.

The top AI search agencies, ranked

1. QCK

Best for: e-commerce and Shopify brands that want AI visibility, SEO and conversion handled by one team.

QCK is an SEO, AI search and conversion rate optimization agency focused on e-commerce and Shopify brands. Its AI search optimization service sits alongside e-commerce SEO, CRO and Shopify web design, so the team that works on getting your brand cited also works on the product and collection pages a cited answer sends shoppers to. Here is what QCK publishes on its own site:

• Testing record. 197 A/B tests across 26 e-commerce stores, with 171 wins (an 86.8% win rate), an average lift of +12.8% per test and $1,214,283 in added revenue, all on the A/B test results page.
• Scale. 7,960 live pages built for clients and 228+ clients served.
• Revenue. $250M+ in organic revenue driven for clients.
• AI visibility. A tracked count of 38,707 AI citations across 16 featured client brands in its case study library.
• Recognition. #181 on the 2026 Inc. 5000.

The case study library shows organic traffic growth for e-commerce brands such as ARMRA (+11,951% in under six months, from 843 to 101.6k), Ballerina Farm (+111% in five months), Hello Cake (+235% in seven months) and Chemical Guys (+46% in about 14 months, from 193k to 283k). That traffic is a third-party estimate from Ahrefs or DataForSEO, and QCK labels it that way.

Consider another agency if: most of your revenue comes from marketplaces such as Amazon or Walmart, where an agency that lists marketplace services on its site may be a closer match.

2. Go Fish Digital

Go Fish Digital calls itself "a generative engine optimization (GEO) and full-service digital marketing agency with 20 years in search." Its services include GEO, SEO, digital PR, paid search and paid social. Ecommerce is listed first among its industries, and it describes marketplace work for Amazon, Walmart and Target, social commerce on TikTok Shop and Instagram, and an ecommerce audit. Its site lists offices in Boston, DC, Phoenix, Raleigh, San Diego and Jacksonville. It ranks second because its site puts ecommerce first among its industries and describes marketplace and social commerce work, which matters for brands that sell beyond their own store.

3. Power Digital

Power Digital calls itself "a world-class, tech-enabled growth marketing agency" and "an AI-native growth marketing agency." Its services include SEO, GEO ("make your brand visible across AI search"), paid media and CRO, with marketplace offerings for Amazon and TikTok Shop. It lists divisions including CPG, fashion, lifestyle, healthcare, consumer services and B2B, and offices in San Diego, New York, Medellín and Atlanta. It ranks third for its consumer focus (CPG, fashion and lifestyle divisions), marketplace offerings and CRO alongside GEO.

4. Siege Media

Siege Media describes itself as "a GEO agency built for the new search" offering full-service GEO. Its site lists GEO, SEO consulting, content marketing, digital PR, Reddit marketing and affiliate partnerships, along with content strategy, design and research reports. It names e-commerce among the industries it serves, alongside SaaS, fintech, health and travel. Its site lists offices in Austin, New York City, Chicago and San Francisco. It ranks fourth because it names e-commerce among the industries it serves and leans on content and digital PR, two of the signals AI answers draw on.

5. iPullRank

iPullRank describes itself as "a pioneering AI Search and content marketing agency" and positions itself as an enterprise and mid-market AI search agency. Its site describes a "Relevance Engineering" approach to how AI models identify and select information, and GEO programs spanning strategy, content, technical optimization and measurement. Its case studies include e-commerce, financial services and automotive and publishing clients. The homepage doesn't state a headquarters location. It ranks fifth because its site lists e-commerce case studies and an enterprise and mid-market focus, which suits large, technically complex catalogs more than smaller stores.

6. NoGood

NoGood presents itself as a growth marketing agency with a full-service AEO practice built on four pillars: AI visibility intelligence and strategy (audits, prompt research, competitive analysis and monitoring), content and owned media optimization, earned media and citation building (digital PR and reputation management), and technical AEO (schema, site architecture and technical audits). It also lists agentic commerce optimization. Its site lists a New York City headquarters with hubs in Miami and Dubai. It ranks sixth: its site lists agentic commerce optimization, but it presents itself as a growth marketing agency across categories rather than a commerce specialist.

7. Ignite Visibility

Ignite Visibility describes itself as a digital marketing agency offering "a comprehensive suite of marketing services all under one roof." Its site lists Generative Engine Optimization alongside SEO and organic social, plus PPC, paid social, conversion rate optimization, content marketing, email and SMS, and web design and development. A 2024 press release announcing its GEO service describes the firm as headquartered in San Diego and says the service covers ChatGPT, Copilot, Perplexity, Gemini and Google AI Overviews. It ranks seventh because its site describes a broad full-service offer, including CRO, that isn't specific to commerce.

8. First Page Sage

First Page Sage describes itself on its homepage as "an SEO + GEO agency" and says it helps clients rank whether customers use Google, ChatGPT or other AI and search platforms. Its homepage emphasizes lead generation, brand authority content, conversion funnel setup, tracking, attribution and reporting. The homepage doesn't state a headquarters city beyond describing the firm as a US agency. It ranks eighth because its homepage emphasizes lead generation, which is a closer fit for B2B and service firms than for online stores.

Side-by-side comparison

This table puts the ranked list side by side: how each agency describes itself, what it lists alongside AI search, and the commerce signals on its own site.

If you sell mainly through your own Shopify store, weigh Shopify and conversion experience heavily. If marketplaces drive most of your revenue, look for agencies that list Amazon or retail media work. If you're a large, technically complex site, look for depth in technical SEO and measurement. For more Shopify-specific options, see our guide to Shopify SEO agencies.

Questions to ask before you sign

Use this sequence in your first two calls. It takes about an hour and filters out most weak fits.

1. Ask for a baseline. "Which prompts would you track for us, and where do we appear today versus our top competitors?" A strong agency can sketch this before you sign.
2. Ask what they'd fix first. Look for specific pages, specific technical issues and a reason for the order, not a generic package.
3. Ask how they connect AI work to revenue. Mentions and citations matter, but you pay salaries with orders. Ask how they'll report AI-referred sessions and conversions in GA4.
4. Ask to see real reporting. Request a redacted example report. Check that it shows prompts, citations and sources, not only rankings.
5. Ask who does the work. Find out who your strategist is, who writes content and who implements technical changes on your store.
6. Ask about terms. Check the contract length, the notice period and who owns content, data and accounts if you leave.
7. Ask what they won't promise. The right answer includes "we can't guarantee placement in any AI answer." Google states plainly that no one can guarantee a number one ranking, and AI answers are even less predictable.

Red flags to watch for

AI search is new enough that some offers are mostly repackaging. These patterns should slow you down.

If an agency recommends an llms.txt file, that's fine as one small step. Our guides on whether you need llms.txt and the free llms.txt generator explain what it does and doesn't do.

Why QCK is our top pick

We said we'd be upfront, so here is the case in plain terms. AI search for a store isn't only about being named in an answer. It's being named, being cited with a link, and then converting the shopper who clicks. QCK is built around all three for e-commerce and Shopify brands.

• One team from citation to checkout. AI search, SEO and CRO sit together, so the pages that earn citations are the same pages QCK tests and improves.
• A record you can check. 197 A/B tests with an 86.8% win rate, 7,960 live pages built for clients and $250M+ in organic revenue driven for clients, all published on qck.co.
• Proof by store, not by slogan. The case studies and A/B test results show the brands, categories, periods and numbers, with traffic labeled as a third-party estimate.

Hold us to the same evaluation table as everyone else. Ask us for a prompt-level baseline, a first-90-days plan and a sample report before you sign.

Choosing your next step

Start by measuring where you stand: pick 20 to 30 prompts your customers would type, check where your brand appears in AI answers and who appears instead, and fix any crawler or schema gaps you find. Then shortlist two or three agencies from this ranked list, run them through the evaluation table, and choose the one that explains your own data most clearly and ties the work to revenue.

For most e-commerce and Shopify brands, we recommend starting with QCK. Book a call and we'll walk through how your store shows up in Google and AI answers against your top competitors.
