When to switch from Google Ads to SEO (and when not to)

Every tradie running Google Ads eventually asks: 'Can I just stop paying per click and rank organically instead?' Maybe. Sometimes. But the way most tradies make this switch costs them six months of leads. Here's the framework.

What each one actually does

Google Ads buys you the top-of-search slot today. You pay per click, the cost is predictable, and the leads start the same week. The downside: the moment you stop paying, the leads stop too.

SEO earns you the same slot, eventually, without paying per click. The downside: it takes 3–6 months for organic, 4–8 weeks for the Google Maps 3-pack, and the early months produce nothing while you wait (see my SEO service for what the work actually looks like).

The trap most tradies fall into

An agency convinces them SEO is cheaper. They drop their Google Ads spend to 'invest the saving in SEO'. For 3 months they get a fraction of the leads. The new business pipeline thins. Cash flow tightens. They panic, fire the SEO agency, restart the ads, but now have to rebuild the campaign from scratch and lose the historical conversion data the algorithm was using.

This story plays out half a dozen times a year in Perth tradie circles. Don't be in it.

The right way: run both during the warm-up

SEO and Google Ads don't compete, they cover different time horizons. The smart move is run both for the first 6 months of any SEO investment, then taper ad spend as organic rankings come online. Cash-flow stays steady, leads keep coming in, and you've got a redundant lead pipeline if either channel gets disrupted.

Concretely: if you're spending $3,000/mo on Google Ads today, don't drop it to $1,500 to fund SEO. Add SEO at $1,000–$1,500/mo on top, keep ad spend the same, and review the split at month 6.

When to actually start tapering ad spend

Watch your organic + GBP-driven calls in your tracking. Once those represent ≥40% of total inbound enquiries (typically month 4–6 of a properly-run SEO push), start dropping ad spend by 10–15% per month. Watch what happens. If total leads stay flat, SEO is filling the gap. If they drop, you're tapering too fast, pull back.

Most established tradies in Perth land on a steady-state mix of 60–70% organic / 30–40% paid. The paid component handles seasonality and surge demand; SEO handles the baseline.

When SEO isn't worth the wait

Some scenarios you should stay primarily on ads:

• You only have 3–6 months of cash runway. SEO won't pay back fast enough.
• You service mostly emergency work (24/7 plumbing, electrical). Google Ads will always carry the urgent searches better than organic ever can.
• You're testing a new service area or trade and aren't yet sure you want to commit.
• Your suburb has dramatically lower CPCs (e.g. Midland), your $1,000/mo of ad spend is cheaper than the same spend on SEO would be.

When SEO is worth doubling down on

• You're an established business in Perth (>2 years), with stable cash flow.
• You've got 30+ Google reviews already, you're halfway to ranking in the local pack.
• Your CPCs are painful (central Perth, premium suburbs).
• You want to reduce dependence on a single channel, sensible long-term hedge.
• You're in a high-volume trade where the same homeowner might search you three times before booking (builders, landscapers).

The honest take

SEO is the long game. Google Ads is the short game. Smart tradies play both. The ones who lose are the ones who pick one and ignore the other, either burning ad budget when SEO would have compounded, or starving today's pipeline waiting for SEO to mature.
