Three years of compounding search work for a family plumbing and heating firm in Edinburgh. They grew from a single van to twenty employees. Here's the part we were responsible for.
Up from one. A business, not a sole trader.
From SEO alone. Sustained, not a launch spike.
Three years in and still compounding.
We are not going to claim we built this business. SD did that, by being good at the job and turning up when they said they would. What we changed is who got to find out about them, and at what scale.
SD are a family-run plumbing and heating firm, built on word-of-mouth and the reputation of good, reliable work. When they came to Arken, the business was profitable and busy, but every enquiry came from the same couple of channels: existing customers, recommendations, and the occasional Checkatrade lead. Search wasn't pulling its weight.
The site reflected that. A handful of indexed pages, most of them thin. A Google Business Profile that was claimed but not optimised. No reviews flywheel. No meaningful visibility in the map pack for their service area. Ranking outside the top 20 for the terms customers were actually typing.
They'd spoken to two other agencies before us. Both sold them technical audits full of issues Google didn't care about. The brief we got was short: "we want the phone to ring more, and we want to understand what's actually happening."
The photographs above are the outcome. This is the channel underneath them, before and after.
Not when they happened. A long-tenured client passes through all four; a newer one might still be in phase one.
The technical and structural work that had to happen before anything else would move. Indexation cleanup, GBP basics, fixing the site architecture so every page had a reason to exist. Quiet work that unlocked everything after.
Building local authority at the map-pack level. Service-area pages with intent, citations tied to real locations, the reviews system that now runs itself. The phase where Google started treating SD as the default answer for "plumber near me" across their catchment.
Content at depth. Problem-first guides for the questions customers type before they're ready to buy, service explainers for the terms with commercial intent, supporting pages that point the right readers toward the right money pages. The phase that compounds.
The work nobody talks about because most agencies never get here. Holding rankings, refreshing content before it decays, responding to algorithm changes, widening the moat. Where SD live now.
Not the whole stack, just the decisions that disproportionately mattered.
We mapped the catchment by postcode, not by city. Every service area that generated regular work got its own page, written to rank against the specific terms customers in that area actually search for. Generic "Edinburgh plumber" pages don't beat pages written for a specific neighbourhood.
Most plumbing sites have pages for their services. We built the library of pages for the problems customers search before they know they need a plumber: the leaking, the knocking, the pressure drop. Those pages rank for early-intent terms, then route readers to the service pages that close.
Before we shipped anything new, we cut what didn't earn its place. Thin pages, duplicates, parameter sprawl. The index shrank before it grew. What stayed was structured so Google understood how it all connected, which made every subsequent page pull its weight.
Reviews are the compounding asset most local businesses leave on the table. We built the process, request timing, message templates and the light-touch chase, so review volume kept growing without SD having to think about it. The reviews still come in every week. We haven't touched the workflow in two years.
The thing that makes Arken different is they tell you when something isn't worth doing. Every other agency we spoke to had a long list of things to sell us. Arken had a short list of things to do, and a shorter list of things to ignore. Three years in, the phone hasn't stopped ringing.
The work isn't over. SD are a live client, and the retainer is structured around the phase they're in now: defending the ground. That means holding map-pack position against newer entrants, refreshing content before it starts to decay, and slowly widening the service-area footprint where the capacity exists to take the calls.
The next twelve months are about deepening what's there, not starting over. That's how most of our oldest client relationships look: the work keeps compounding, the output keeps mattering, and the monthly retainer still earns its place because the phone keeps ringing.
