Who are the best SEO agencies in the UK?
Twenty UK SEO agencies, read page by page and scored against seven criteria. Every claim we could check, we checked against third-party data. Independently reviewed and edited.
What we did
We opened 904 case studies across twenty UK SEO agencies, one at a time rather than counting them from an index page. We read every services page, every team page, every pricing page where one existed, and each agency’s own Google reviews.
Then we checked the strongest claim each agency publishes against that client’s own traffic data, which is the part most rankings skip.
Where we looked and found nothing, we recorded that we looked. A blank cannot be told apart from nobody checking, and a ranking that cannot tell those apart is measuring itself.
Quick verdict
The top three
The three highest totals of the twenty. Every figure here is the one in the full table below.
Buried
Scores 7.8 overall, with its strongest ground on AI search capability and proven outcomes. It publishes what the work costs, from £1,200 a month, which fourteen of the twenty do not.
The SEO Works
Scores 7.4 overall, with its strongest ground on proven outcomes and AI search capability. It publishes no price for the work itself. Its strongest published claim, for House of Oak, holds up against that client's own traffic data.
Pearl Lemon
Scores 7.2 overall, with its strongest ground on proven outcomes and reviews and references. It publishes what the work costs, from £3,000 a month, which fourteen of the twenty do not. Its strongest published claim, for Pixel Field, holds up against that client's own traffic data.
What we found
- Naming the client is the norm, not the differentiator. 20 of the twenty name clients in their case studies. What separates them is whether a period is stated alongside the figure, and whether the claim survives a check.
- 8 of the claims we checked stood up. We took each agency’s strongest published claim and compared it against that client’s own traffic data.
- 5 could not be checked at all, because the figure quoted was a ranking position, an impression count or revenue. None of those is visible to a third party. That is a fact about how the case study was written, not a mark against the work.
- Only 7 of the twenty publish a price for their own SEO work. 4 publish nothing at all and 9 answer the cost question by saying it varies. Several sites carry prices that look like an answer and are not: a software subscription, a client’s campaign budget, or the market rate rather than their own.
- The AI search column is the second heaviest of the seven, at 25%, behind proven outcomes at 30%, and it is not our opinion. It comes from our sister study at bestgeoagencies.co.uk for the eleven agencies in it, and is assessed here on the same four measures for the nine that are not. That study is published by Buried, which also appears in this ranking, and we say so on every page it touches.
- The top of the table is close. Buried, The SEO Works and Pearl Lemon are separated by 0.6 of a point, so treat the order as a shortlist rather than a verdict, and read the rows rather than the ranks.

Every band was written down before a single agency was read, so the study could not fit itself to its own answer. The order is recorded and can be checked.
Each agency’s strongest published claim is compared against that client’s own traffic data, and lands in one of three states. Where a claim cannot be checked we say so rather than counting it.
A blank in this table means we looked. Where a source would not open, the row says that instead, because that is a fact about us rather than the agency.
This site is published by Buried, which appears in the ranking and is scored by the same protocol as the other nineteen. Agencies can pay to be included and read. None can pay for a position.
The agencies in detail
The top ten, criterion by criterion, with the reasoning and the sources behind every score.
Buried
| Criterion | Score | What we found | Sources |
|---|---|---|---|
| Proven outcomes30% | 8 | 14 case studies read, one page at a time. 14 are SEO-led rather than paid. 7 name the client. 14 carry a figure that belongs to that client, and 4 carry that figure alongside a stated period. Excluded as sitewide furniture: 35 per cent, each appearing on a third or more of their case studies and therefore belonging to no one client. | 1234 |
| AI search capability25% | 8.2 | Scored 8.2 out of 10 in our sister study at bestgeoagencies.co.uk, which reads each agency against a tracked prompt set and seven criteria of its own. The figure is carried across unchanged. That study is published by Buried, and so is this one, so this score is Buried marking its own work on a criterion carrying 25 per cent. It is stated here, on the row it affects, rather than in a footnote. | 1 |
| Reviews and references15% | 8 | 5.0 out of 5 from 25 Google reviews, Google Business Profile on Maps, opened directly. Band set on volume and recency; reaching 8 or 10 needs the reviews themselves read for whether they describe SEO work and whether any client is named, which is the next pass. | |
| Measurement approach10% | 8 | 5 measurement tools named on their own pages: Ahrefs, Google Analytics, Moz, Search Console, Semrush. 190 references to a business metric such as revenue, leads or ROI across 20 pages read. A reporting rhythm is stated. | |
| Published research10% | 8 | Two original data studies: the UK AI Curiosity Map, which ranks cities by AI-related search volume against population, and an AI adoption map built from search data across 35 UK towns and cities. Method stated in both. | |
| Team and reputation5% | 4 | 1 named practitioner with a role: Will Tombs. | |
| Pricing transparency5% | 8 | A package table repeated across six service pages: one-off audits from £2,000 to £12,000, migration support from £4,000 to £15,000, and monthly retainers at £1,200 to £3,000 for small business, £3,000 to £8,000 for medium and £8,000+ for enterprise, with what each tier includes listed beside it. No day rate or rate card is published, which is what the top band needs. | 1 |

| Reviews and references15% | 8 | 4.4 out of 5 from 93 Google reviews, Google knowledge panel, read from a search for the agency. Band set on volume and recency; reaching 8 or 10 needs the reviews themselves read for whether they describe SEO work and whether any client is named, which is the next pass. | |
| Measurement approach10% | 6 | 5 measurement tools named on their own pages: Ahrefs, Google Analytics, Screaming Frog, Search Console, Semrush. 32 references to a business metric such as revenue, leads or ROI across 32 pages read. A reporting rhythm is stated. | |
| Published research10% | 6 | A jobs study built from data, published as original analysis. The other candidates matched a sidebar rather than their own article text. | |
| Team and reputation5% | 4 | 2 named practitioners with a role: Ben Foster, Neil Palmer. | |
| Pricing transparency5% | 2 | No price published for their own SEO service. They run a page explaining how SEO costs and pricing models work, which addresses the question without answering it for themselves. The currency figures on their site are an example search query, industry ROI ratios and a charity donation, none of which is a price they charge. | 1 |

How we score
Seven criteria, the same seven for every agency, weighted as shown.
Proven outcomes , 30%
Can they show SEO results for named clients over stated periods, and do those results survive a check against third-party traffic data?
AI search capability , 25%
Can this SEO agency do GEO, AIO and AISearch at all, and is there evidence rather than a service page?
Reviews and references , 15%
What SEO clients say on the agency’s own Google profile, weighted for whether the review is about SEO at all.
Measurement approach , 10%
How they measure SEO: which tools, which metrics, what reporting rhythm, and whether it reaches revenue or stops at rankings.
Published research , 10%
Original SEO research using their own data, against repackaging someone else’s.
Team and reputation , 5%
Named SEO practitioners with roles and visible track records.
Pricing transparency , 5%
Whether SEO prices are published, and what is included at each level.
The verdict
Who comes out ahead, and on what.
Buried
Scores 7.8 overall, with its strongest ground on AI search capability and proven outcomes. It publishes what the work costs, from £1,200 a month, which fourteen of the twenty do not.
The SEO Works
Scores 7.4 overall, with its strongest ground on proven outcomes and AI search capability. It publishes no price for the work itself. Its strongest published claim, for House of Oak, holds up against that client's own traffic data.
Pearl Lemon
Scores 7.2 overall, with its strongest ground on proven outcomes and reviews and references. It publishes what the work costs, from £3,000 a month, which fourteen of the twenty do not. Its strongest published claim, for Pixel Field, holds up against that client's own traffic data.
ClickSlice
Scored 8.2 out of 10 in our sister study at bestgeoagencies.co.uk, which reads each agency against a tracked prompt set and seven criteria of its own. The figure is carried across unchanged, and that study is published by Buried, which also appears in this ranking.

What an SEO agency costs
4 of the twenty publish no figure at any level, and 9 more answer the question without answering it, saying costs vary and to ask. The bands below come only from the 7 that do publish a figure, so they describe what is actually on the market rather than a survey we did not run.
| What you are looking at | Entry | Mid | Enterprise |
|---|---|---|---|
| Published monthly spend | £1,200 to £3,000 a month | £3,000 to £8,800 a month | £8,000 a month and up, to around £20,000 |
| Who you actually deal with | A shared team and a named contact | A named strategist on the account | A team with a lead and senior people named |
| What the work is | Technical fixes, on-page work and a content plan | Content, digital PR and technical together | Migrations, international and AI search |
| How often you hear | Monthly reporting | A monthly call and a live dashboard | Weekly contact |
| Who it suits | Best for a single-location business or a small catalogue | Best for a growing ecommerce or B2B brand | Best for multi-market or multi-brand |
A note on those numbers
Treat any published price as a floor rather than a quote. An agency that publishes £1,200 a month is telling you where its cheapest package starts, not what your job will cost.
The more useful question is what you are buying at each level. At entry you are usually buying someone’s time in small amounts and shared attention. The jump in price between tiers is mostly a jump in seniority and in how much of the work is strategy rather than execution.
Agency, freelancer or in-house
Three ways to resource SEO. The right one depends less on the label than on how much expertise you need, how consistently you need it, and how much management you want to keep in house. Only the agency column carries a price here, because the agency column is the only one this study measured.
| What you are comparing | Agency | Freelancer | In-house |
|---|---|---|---|
| Cost | Published prices in this study start at £1,200 a month and reach about £20,000 | Varies by practitioner and scope | Salary and employment cost rather than a monthly fee |
| What you get | Several disciplines without hiring each one | Direct access to the person doing the work | Full-time knowledge of your business |
| Flexibility | Scope goes up and down as the work changes | Simple to start and stop | Slow to change once hired |
| The catch | Your attention is shared, and the people selling may not be the people delivering | One person cannot specialise in every part of SEO, and capacity is a limit | One hire rarely covers every discipline, so specialist support often continues |
| When it suits | Suits a job that crosses technical, content, digital PR and measurement | Suits a narrow job where you know what is missing | Suits a permanent need with enough work to fill the role |
Which one, honestly
Start with the work rather than the supplier type.
If the job is narrow and you know which expertise is missing, a specialist freelancer will usually start sooner and cost less than a retainer. If SEO is strategically important and there is enough of it to occupy somebody permanently, a hire gives you ownership and proximity. An agency makes most sense when the job crosses disciplines, or needs more capability than one person can hold.
Whichever route you take, the questions are the same: who is doing the work, what evidence can you check, what gets measured, how often will you see it, and what exactly are you paying for?

FAQs
Why is my agency not on this list?
We considered 116 UK SEO agencies and published twenty. Of the 96 that did not make it, 62 failed one of the inclusion rules and 34 passed the rules but fell below the cut line used to pick the final group. Agencies can apply to be assessed. Paying for an assessment does not buy a position.
How is this ranking put together?
Twenty agencies, seven criteria, each scored out of ten against bands written down before any agency was read. Every case study is opened individually rather than counted from an index, and the strongest claim each agency publishes is checked against that client’s own traffic data. The full method is on the methodology page.
Can an agency pay to be on this list?
An agency can pay to be included, which means we read it and score it against the same seven criteria as everyone else.
No agency can pay for a position, and none has. Where an agency lands is determined by its score.
Buried publishes this site and appears in the ranking. How is that independent?
It is stated rather than hidden, which is the most we can offer.
Buried is read and scored by the same protocol as the other nineteen, against bands set before any agency was read, and its weakest criterion is published alongside its strongest. You can check every score against the sources listed beside it.
Why do some claims say they could not be checked?
Because the figure quoted is a ranking position, an impression count or revenue, and none of those is visible to a third party.
That is a fact about how the case study was written, not a mark against the work, and we will not present it as one.
How often is this updated?
The whole study moves as one job: the reading, the scores, then every page rebuilt from them. Lists refreshed on separate schedules start contradicting each other, and nobody notices until a reader adds the numbers up.
