Google Ads vs Local SEO: Which Should South London Trades Businesses Use First?

Both Google Ads and Local SEO can fill your diary with qualified leads. But they work very differently — and for a trades business starting out, choosing the wrong one first can cost you time and money. Here's the honest comparison.

If you're a South London trades business starting to invest in digital marketing, you'll almost certainly face this question early on: should I run Google Ads or focus on Local SEO?

Both channels can deliver real, qualified leads. But they work in fundamentally different ways — and starting with the wrong one for your situation can mean spending money without seeing results, or waiting months longer than necessary to get traction.

Here's the honest comparison.

What Google Ads actually does

Google Ads puts your business at the top of search results immediately — above the Local Pack, above organic results, above everything. You pay each time someone clicks your ad. When someone in Clapham searches 'kitchen fitter near me', your ad can appear within hours of setting it up.

The key word is 'pay.' The moment you stop running ads, you disappear. There's no residual benefit. Every lead costs money, and as more competitors bid on the same keywords, that cost tends to rise over time.

For South London trades businesses, Google Ads typically costs £300–£800/month in ad spend on top of any management fee, depending on your trade and target area. Kitchen fitting and bathroom renovation are competitive — expect to pay £8–£25 per click in some South London postcodes.

What Local SEO actually does

Local SEO builds your organic presence on Google over time — your ranking in the Local Pack (Google Maps), your position in regular search results, and the authority of your website. Unlike ads, you don't pay per click. Once you rank, the leads are essentially free.

The trade-off is time. Meaningful Local SEO results typically take 3–6 months to appear. You're building an asset rather than buying traffic — which means the returns compound over time rather than stopping the moment you stop paying.

The honest comparison

  • Speed: Google Ads wins — results within days vs months for SEO
  • Cost per lead long-term: SEO wins — no cost per click once you rank
  • Sustainability: SEO wins — rankings persist, ads stop when budget stops
  • Control: Google Ads wins — you can turn it on and off, target specific areas and services precisely
  • Trust signals: SEO wins — organic results and Google Maps listings are trusted more than ads by many searchers
  • Setup complexity: Similar — both require expertise to do properly

Which should you use first?

For most South London trades businesses, the answer depends on one question: how urgently do you need leads?

If your diary is empty and you need work within the next 30 days — start with Google Ads. A well-set-up campaign targeting your specific trade and South London postcodes can generate enquiries quickly. Use it to keep cash flowing while your SEO builds in the background.

If you have some existing work coming in and can afford to think 6 months ahead — prioritise Local SEO. The compounding returns mean that by month 6, your cost per lead is a fraction of what Google Ads would cost for the same volume.

The smartest trades businesses use both — Google Ads for immediate, controllable lead flow, Local SEO for long-term sustainable growth. Our Growth package at £1,500/month includes both, working together as a joined-up strategy.

What to avoid

The most common mistake we see is trades businesses running Google Ads without a proper website or Google Business Profile in place. If someone clicks your ad and lands on a slow, thin website with no reviews and no clear call to action, the click is wasted. Ads amplify what's already there — if what's there is weak, you're paying to accelerate poor results.

Before running any paid traffic, make sure your Google Business Profile is complete, your website loads quickly on mobile, and you have a clear way for visitors to contact you. These are the foundations everything else sits on.
