Most agencies treat ChatGPT, Perplexity and Google AI Overviews as an afterthought. We build SEO in Grays around all of it from day one, so technical search, AI visibility and digital PR are one job rather than three invoices.

This is an instant, live ballpark quote calculator. You’ll see a project range and flexible payment options, including pay over time and monthly retainer costs.
Step 1 of 2Enter your website (or the one you’d like) to start:


We help Grays businesses hold the full search picture, from page one on Google to the answer somebody gets from ChatGPT or Gemini. That means sharpening the technical setup and matching content to how people search now. Done properly, you stay visible and recommended across Grays, Chafford Hundred and the rest of Thurrock rather than ranking for your own name and nothing else.
The strategy starts with data, never assumptions. The first audit exposes the technical errors bottlenecking the site, finds the pages underperforming and takes apart what your competitors are doing to stay above you. Work then follows a strict order of impact: technical fixes, then high-intent content, then link building worth the name, all pointed at your authority in Grays.
You end up ranking for the Grays terms people search and hearing from buyers rather than browsers. Forecasting gets easier once organic carries a steady share of enquiries, and the ad budget stops being the thing holding the diary up. Recent projects show the standard, and the person answering your questions is the person doing the work.

Any agency can pull a keyword list. We go through yours line by line and work out which terms bring people ready to spend, which bring readers, and which the assistants are already answering without a click. What comes out is a plan of pages worth writing for the Grays market.
On-page work comes before links, because a link to a page that misses the intent moves the wrong page. We set each page against one search, fix the structure and internal linking, then format the answer so Google and the assistants can quote it directly.
We audit the site and then look after it. Speed, mobile behaviour, architecture, index coverage and server performance, ranked by what each fault is costing rather than how long it takes to fix. On most sites the technical work is where the first movement comes from.
Grays sits inside Thurrock, so your map results compete with businesses filed under Chafford Hundred, Little Thurrock and Tilbury as well as Grays itself. We build the Google Business Profile to hold across that spread, sort categories and photos, keep reviews arriving and clean the citations. Those same signals decide who the AI assistants recommend nearby.
Outreach by hand, to sites people in your industry read. Publishers, journalists and businesses around Grays and Thurrock that you already deal with. Nothing bought, nothing farmed. You see the link, the site and the effect it had. One relevant local link is worth more than twenty directory entries.
One report a month from the person doing the work. Enquiries first, then rankings, traffic and the terms behind them, then how often you're being cited in AI answers and who's there in your place. The first one lands after 30 days, and there's a call with every report.
We audit the lot: technical health, page by page performance, and how you show up against firms filed under Chafford Hundred, Little Thurrock and Tilbury as well as Grays. We also check what ChatGPT and Gemini say when asked who to use. Plan in writing by day fourteen.
Weeks three to six are for fixing. Technical faults first, ranked by what they cost you. Then on-page work so each page answers one search properly, and a Google Business Profile built to hold across Thurrock. Content for the Grays terms worth having starts here.
Reporting lands at 30 days and monthly after that. It leads with enquiries and works back to rankings, traffic and the terms behind them, plus how often AI answers name you. There's a call with every report, and the work goes where the numbers say it should.
Forty second answers with no jargon. Anything else, ring the office and ask whoever picks up.
Early movement in two to three months and something meaningful by six. The variable is your starting point. Fixing a site that's being held back is quick work with a quick payoff. Building content and links where there are none is slower, because the thing that ranks has to exist before it can rank. Competitive national terms can take a year, local terms are usually faster. We give you a timeline after the audit rather than a promise on a sales call.
It's a monthly retainer, starting from £1,000. Nobody can price SEO properly without looking first, because the same service costs different amounts depending on what's in front of it. Forty competitors is more work than four. A site with technical faults needs those cleared before content will move. National reach costs more than local. We price against your situation rather than a package tier, and you see the figure before you commit to anything.
Either can work. What matters is that the work is sequenced and that it keeps happening. Random blog posts and a plugin that turns your pages green won't move you. The order is technical repairs, then pages built against real search terms, then links from outreach, then measurement that says what to do next month. An agency gives you that in the weeks when your own week goes sideways.
Search is splitting into two habits and you need both covered. Some people still type into Google and scroll. Others ask an assistant and take the first answer. The underlying work overlaps almost entirely, because the assistants read pages that already rank. The difference is formatting and citation, and both are part of the retainer rather than an add-on with its own invoice.
No. We're a Basildon agency and we work across Essex, London and the rest of the UK. Most of the job happens in your site and in the search results rather than in a room. What being close buys you is the option of meeting face to face and a head start on the market research. Knowing that a term means one thing in Grays and something else twenty miles away is the sort of detail an agency that's never been there misses.
The biggest advantage of SEO is being found by people who are already searching for what you sell, which is a cheaper way to be seen than paying for every click. Over time that builds more than traffic. Small businesses that keep appearing at the top get treated as the established option, and that credibility is worth as much as the visits.
Cold works from Chester Court in Basildon, around 20 minutes from Grays on the A13. It started in a bedroom with one person working two jobs, and it has grown on referrals, which still bring in nine out of ten new clients. You won't meet an account manager. You'll meet the people doing the work.
Search sits alongside the rest of what we do. If the site needs rebuilding, our Webflow web design team handles it in the same building, and our digital marketing covers the channels SEO can't reach on its own. Grays businesses get one team for all of it.
