Disclosure first. We run alwayscited. We put it at number one, and below we say why, and where it is not the right fit. The useful lists say so. So do we.
How we ranked them
Every agency on this list says it can get you into AI answers. Few let you check that before you pay. We ranked on four things a buyer can verify:
- It measures the answer, not a proxy. Does it put your buyers' prompts to the engines and report whether you were named, engine by engine?
- It works where the answers come from. Does the agency get you into the third-party pages the engines cite for your category, or does it only work on your own site?
- The price is published. Can you see what it costs without a sales call?
- It reports on its own work. Does every piece of work come back with whether it changed what the engines said?
Where we describe another agency, it is from how the agency describes itself on its own site, read on 28 September 2026. We do not score other agencies, and we do not quote their prices.
1. alwayscited - best for being named in the answer, with the price on the page
It is an AI SEO agency service, built and run by the senior team at nomada digital, a search agency in York, in the UK.
- It starts with the measurement. The free scan writes 5 buyer prompts for your category, puts each to Google AI Overviews, ChatGPT, Gemini and Perplexity, and shows all 20 answers, with the pages each engine cited. No email needed to see it.
- It places where the engines already read. The placement tiers put your brand into the third-party pages the engines are already citing for your topic, so you are named inside the answer rather than ranked in the links under it.
- Every placement is reported. Each one comes back with whether the engines now cite it.
- The prices are published. alwaystracked is from $129 a month for 10 clusters: 50 prompts and 10 keywords, checked daily. The placement tiers are priced by sector on the packages page. Monthly, no minimum term.
- Agencies can resell it. alwaystracked to alwayscited are white-label.
Not the fit if you want one agency to run your paid media, social and site build as well. We do one job.

What to ask any AI SEO agency, including us
- Which prompts will you track, and on which engines?
- Can I see the answers, not just a score?
- Which pages are the engines citing for my category today, and will you work on those?
- What does each piece of work cost, and what will you report back on it?
- What happens if nothing moves in three months?
If an agency cannot answer the first three before you sign, it is guessing.
The free LLM visibility checker shows whether the engines name you today, who they name instead, and which pages they are reading. Run it on your domain - it takes about two minutes.
