Niche down is the only way you'll survive the first six months without burning out. I've seen too many agencies try to be a jack of all trades and end up with a dozen half-baked campaigns that bleed cash.
Here's how I'd approach it:
1. Pick one service + one vertical
"Google Ads for local plumbers" is a textbook example. Better yet, add a data hook: "Screaming Frog audits + GSC analysis for local trades." That's my playground - you can spot technical gaps competitors miss.
2. Build the offer around a measurable deliverable
Don't just say "we'll run ads." Say "we'll triple your booked calls within 90 days, tracked via GTM click events and call extensions." Clients love concrete numbers.
3. Cold outreach with a data carrot
Forget generic cold emails. Run a quick Ahrefs or GSC report on their site, find a real issue - like missing schema or slow landing pages - and mention it in the subject line. "I spotted your contact page is broken on mobile" gets opened.
4. First two clients will be cheap or free
Took me two pro bono plumbing accounts to build case studies that actually closed deals. Track everything with UTM parameters in Google Analytics and serve them a dashboard. That proof alone is worth more than any pitch deck.
LinkedIn and Facebook groups work, but focus on one group where local biz owners actually ask for help. Don't post generic tips - share a real Screaming Frog export from a competitor's site and highlight what's missing.
The hardest part? Staying disciplined when a random e‑commerce shop offers you £2k. Decline it. That's how you build a reputation, not a mess.
