Edition updated 9 Oct 2026

Most agency websites in London are a wall of percentages with no baseline, no date and no source, under a headline that calls the agency the best. We built this one so you can check ours. Every number names the client it belongs to and where it was read. Where a project has no figure, the page says so in those words.

What you will find here

  • Case figures with the client, the source and the date they were read, including the rows where no figure is claimed.
  • A team of 21 named people with real roles and photographs, and the group behind them labelled as the group.
  • Indicative prices with the proposed terms on the first line: no minimum term, 30 days' notice, no exit fee, confirmed in writing before you sign.
  • A free audit done by a person, in writing, within two working days, with no call required first.

Case study

Whetstone, London N20

Blac, Whetstone, London N20: photograph
Blac, Whetstone, London N20. Signature plates.

A restaurant in N20, found by the people who eat out there

A reels-first content engine built around the kitchen and the room: the team that shoots the food runs the channel, so the plates, the cocktails and the lounge are photographed and posted by the same people, and the channel that shows the food is the one that reminds happy guests to leave a review. The work was social media marketing and reputation management; no search campaign is claimed.

What it shows a London business

  • A London restaurant is chosen on a phone, in seconds, from a map pin, a rating and a few photographs. The content that fills the room is the same content that earns the next review.
  • Reviews and social are one system. The channel that shows the plates is also the channel that reminds happy guests to say so.

How we work

The first 90 days, 5 steps

  1. Days 1 to 2

    A person reads your site

    Send the address and a person reads it by hand. You get their name the same working day and the written review within 2 working days. No automated score, no call required first.

  2. Week 1

    The audit, in writing

    If you go ahead, the audit becomes a plan: what is holding the site back in London search, in what order we fix it and what each fix should move. Access to Analytics, Search Console and your Business Profile is set up in your name, never ours.

  3. Month 1

    Deliverables listed, not implied

    The month-one list for your tier is on the pricing page, in your written quote and on your first invoice. If a listed month-one deliverable is missed for a reason within our control, that month is credited.

  4. Month 3

    A report you can forward to your accountant

    By the fifth working day of each month you get a written report drawn from Search Console and GA4, so every line can be checked against the source. At month three we sit down, at Tower 42 or on video, and decide together whether to continue.

  5. Any month

    How you leave if it is not working

    None. Month to month. 30 days' written notice, including in month one. No exit fee. Everything from month one is yours to keep. These terms are proposed and are confirmed in writing before you sign.

What we will not do

Our code of ethics, in full

  • Guarantee rankings.

    Nobody can, and a promise like that would breach the UK advertising code. We guarantee the work instead, and list it month by month.

  • Buy links.

    Every link we earn is earned: a mention, a citation, a piece worth linking to. No paid networks, no link farms, nothing we would not show you the invoice for.

  • Invent reviews or star ratings.

    We show no rating of our own until a public profile exists to read it from. The ratings on this site belong to our clients, with the date each one was checked.

  • Lock you in by stealth.

    The terms are on the pricing page and the Before you sign page, in the same words as the contract. Nothing renews behind your back.

  • Call a sales call a free audit.

    The free audit is a written review by a person. You can read it, act on it and never speak to us, and it is still yours.

  • Minimum term

    None. Month to month.Proposed terms, confirmed in writing before you sign

  • How you leave

    30 days' written notice, including in month one. No exit fee. Everything from month one is yours to keep.Proposed terms, confirmed in writing before you sign

How to choose an SEO agency in London

Questions

10 questions

Looking for an SEO agency near me in London?
We work from one office, at Tower 42, 25 Old Broad Street, London EC2N 1HN, in the City, and we visit clients across all 33 boroughs. Meetings at Tower 42 are by appointment, a short walk from Liverpool Street and Bank. If you are searching from Croydon, Ealing, Hackney or anywhere between, the work is delivered the same way: by the same named team, from the same office. Find your area on our London pages or send a brief.
Do you guarantee rankings?
No, and we will not. Google itself says nobody can guarantee a ranking, and a promise like that would breach the UK advertising code. What we guarantee is the work: every month-one deliverable for your tier is listed on the pricing page, and if we miss one that month is credited. Every result we publish names the client, the figure, the source and the date it was recorded. Our position on guarantees is written in full in the code of ethics.
How long does it take?
Technical fixes are usually re-crawled within two to eight weeks. Local search changes often show within one to three months. Competitive London head terms usually take six to twelve months. These are typical ranges from our own work, not a promise for your site, and we report progress every month so you can see which it is. The longer answer, with what moves each range, is in our guide on how long SEO takes.
What happens in month one?
A hand-written technical and content audit, a map of the searches that matter to your business with London demand, Google Analytics, Search Console and your Google Business Profile set up or verified in your name, a live reporting dashboard, a 90-day roadmap and the first fixes made. The exact list for each tier is on the pricing page, and the full first 90 days, day by day, is on how we work. If a listed month-one deliverable is missed for a reason within our control, that month is credited.
Will I be locked in?
No. None. Month to month. 30 days’ written notice, including in month one. No exit fee. Everything from month one is yours to keep. There is no auto-renewal and no requirement to set up a standing order. The same sentences appear on the pricing page, in your written quote and in the contract, and they are set out in plain English on Before you sign. These terms are proposed and are confirmed in writing before you sign.
Are you really in London?
Yes, with one honest qualification. The London office is at Tower 42, 25 Old Broad Street, EC2N 1HN, and visits are by appointment rather than a walk-in reception. The company’s head office is in Slough, with further offices in Birmingham and Manchester. We say "by appointment" on every page because that is what is true. Directions and hours are on the contact page.
Who does the work?
21 named people with photographs and roles, led by a UK account lead you can name and phone, who replies within one working day. Specialist work can draw on colleagues across the group’s 10 countries; when it does, we tell you who. Nobody on your account is anonymous and nothing is handed to a reseller. Meet the team.
How much does SEO cost in London?
It depends on three things: how competitive your boroughs and sector are, how many locations you have and how large the site is. We sell three SEO retainers and two local SEO tiers, each with its month-one list and the terms printed on the first line, and every figure is on the pricing page rather than hidden behind a call. For what the London market charges, with every range sourced, read how much SEO costs in London.
Why is the company only two years old?
Because that is when the UK company was formed. Hulk Marketing Ltd was incorporated on 2 September 2024 (Companies House 15931335). The group behind it has traded since 2012 as Google Ranker Pro, with 220 experts in 10 countries and 700+ projects across the group. We say which is which, on every page, and we do not describe the group’s history as London’s. More on the about page.
What do I own if I leave?
Everything. Accounts, content and links are created in your name. Google Analytics, Search Console, your Business Profile, ad accounts, domain, website files, content, images and every link we earn stay yours, with us as a delegated user while we work. On exit, access is handed over and ours is removed. We never ask for passwords. The full list is on Before you sign.
