SEO vs Google Ads: Which Should a Local Business Pay For?
Ads rent the spot, SEO owns it. The honest side-by-side for local businesses, including the cost-per-lead maths over time and the combined play we actually recommend.
Two Cairns plumbers, same suburb, same budget. One puts $1,500 a month into Google Ads: leads by Friday, and a meter that never stops running. The other puts it into SEO: three quiet months, then rankings that keep producing after the spend stops. Ads buy speed, SEO buys ownership, and for most local businesses the right answer is a sequence of both, not a religious choice of one.
The honest side-by-side
| Google Ads | SEO | |
|---|---|---|
| First leads | Days | 2-3 months, compounding after (timeline) |
| Cost model | Management + pay per click, forever | Monthly work that builds an asset |
| When you stop | Leads stop same day | Rankings persist, decay slowly |
| Trust factor | Marked “Sponsored”, some skip it | Organic + map results read as earned |
| Cost per lead over time | Flat or rising (auction pressure) | Falls as rankings compound |
| Best at | Instant demand capture, promotions, new businesses | Owning your market long-term |
The cost-per-lead maths that decides it
Simplified but honest: suppose clicks in your trade cost $8 and one in ten becomes a lead, that is $80 a lead on ads, every lead, forever, plus management. An SEO campaign at $1,500 a month producing 40 leads a month by month twelve is $37 a lead and falling, because next month’s leads come from the same pages at the same cost. Ads win the first quarter. SEO wins every quarter after. Our client Cairns Auto Works is the end state: 300+ organic leads a month with zero per-click cost.
When ads are genuinely the right call
- You are new and the diary is empty: SEO cannot feed you this month, ads can.
- Seasonal pushes: wet-season roofing, EOFY, storm cleanups.
- Testing demand for a new service before you build pages for it.
- The keyword is brutally competitive and you need presence while the long game runs.
When SEO is the better dollar
- You plan to be in business in five years. Ads are rent, SEO is the deed.
- Your market searches with local intent (“your trade + cairns”), where map-pack and organic results dominate clicks.
- Margins are tight: per-click costs eat thin margins, owned rankings do not.
The sequence we actually recommend
- Fix the site first. Ads pointed at a slow site burn money on both fronts. (The 7 leaks.)
- Run both for 6-12 months: ads ($500/mo management + your budget) fill the diary while the campaign builds.
- Dial ads down as rankings land. Keep a small always-on budget for the terms SEO has not cracked yet, drop the rest.
