The 21 Degrees difference
An AI SEO agency that shows its working
Google says AI search is still search. So do we.
Its own guide to AI features says AI Overviews and AI Mode run on the same index and the same ranking systems as the blue links. No magic file gets you in. Anyone selling you an llms.txt as the secret is selling you a text file.
The price is on this page.
Scroll down. Three tiers, real numbers, no "book a call to find out". We'd rather you knew before you asked.
We test copy the way machines read it.
21 Degrees Digital runs every page through natural language analysis before it ships, so we know how search engines and AI models classify it, not how we hope they do.
Brand and performance as one system.
AI engines cite brands people already talk about. So PR, SEO and content run together here. That's Outcome Marketing, and it's why the citations turn into pipeline.
The process
How we get you ranked and cited
21 Degrees Digital delivers AI SEO services in six steps. None of them is "add AI to the page title and hope".
AI visibility audit
Where you show up now, on which engines, for which questions. And who's being cited instead of you.
01
Foundations
Crawlable, fast, clean, readable by every bot that matters. Our technical SEO team fixes what's holding you back.
02
Answer-first content
Pages that answer the question in the first sentence, written by humans, checked by machines. That's our SEO copywriting lane.
03
Authority and mentions
Coverage in the places AI trusts, through digital PR. Mentions do the job links used to.
04
Entity and schema work
We make it obvious to every engine who you are, what you do and why you can be trusted.
05
Measure and refine
Rankings, citations, share of AI answers and the enquiries behind them, reported straight. Winners get more budget.
06
THE 21 DEGREES CONTENT ENGINE
One recording. Four formats. Every engine.
Different AI engines trust different sources, so one blog post and a prayer won't do it. We film your experts once, then cut that single recording into the exact formats each engine pulls from. This page was built the same way.
01
Create
Record long-form video or audio with your experts. The dense, genuinely useful source asset. Recorded once, re-cut everywhere.
02
Mark up
Transcribe it, mark it up with schema, publish it with footnoted stats, quotes and source links.
03
Distribute
Push the video to YouTube, hand the assets and stats to PR, earn the coverage.
04
Amplify
Cut it into short social clips. Post fast, post often. Recency counts.

Pricing
Ways to work with us
We sell days, not channels. Pick the firepower that fits where you are now, and scale when the results say so. All plans are monthly.
A brand-new eCommerce site with no authority, taken to page one through a purely on-page SEO strategy. Unique copy and a product-led resource hub did the heavy lifting.

Low search volume, high-value deals
Metrics
In a specialism where total search volume is tiny, intent is everything. A handful of well-ranked long-tail pages outperformed any generic content programme.
Before 21 Degrees, we were not appearing for AI searches through LLMs or Google, now we're getting new leads from ChatGPT every day. They didn't just improve our SEO. They transformed our entire business trajectory. We've had to hire two new staff to handle the enquiries.
An AI SEO agency gets your business ranked in Google and cited in AI-generated answers from ChatGPT, Gemini, Perplexity and Google's AI Overviews. It does the SEO fundamentals first, technical health and content and authority, then adds the layer AI engines look for: clear entities, answer-first pages and brand mentions in the sources they trust. 21 Degrees Digital runs both as one programme, because they're built on the same index.
How much does AI SEO cost?
Our AI SEO retainers start at £1,600 a month for two days of work and scale to £6,400 for eight. We sell days, not channels, so the same tiers cover Google and the AI engines together. Most clients sit in the middle tier. The numbers are on this page.
Do you use AI to do the SEO?
Yes, and we're not going to be shy about it. AI handles research and first drafts at a speed no human can match. Humans decide the strategy, write the final words, check every fact and put their name on the work. Google doesn't penalise AI-assisted content. It penalises unhelpful content, and so does every other engine.
Can ChatGPT or an AI agent just do my SEO?
It can do some of it, and we use those tools ourselves. What it can't do is know your business, judge what's worth publishing, earn a mention in the trade press or own it when something goes wrong. Fully automated SEO tends to produce content that reads like everyone else's, which is exactly what AI engines skip past. That goes for every sector we work in, from finance to ecommerce.
Which AI SEO agency is best?
The best AI SEO agency, company or consultant is the one that can show you five things: strong traditional SEO underneath, named results with numbers, pricing you can see, a measurement method for AI visibility, and a human accountable for the work. Ask any agency for those five before you sign. We've put ours on this page so you don't have to ask.
AI SEO or GEO, which do I need?
Most businesses need both, and they're two layers of one job. AI SEO gets you ranked in Google and cited in AI answers, built on your search fundamentals. Generative engine optimisation, or GEO, goes deeper on being the source AI names: citation building, entity work and AI visibility tracking across every engine. Some people call the whole thing an AI search agency. Start here, then read our generative engine optimisation page for the deep dive.
