This is one of the most common questions we get from prospective clients, and the honest answer is “it depends” — but there’s a genuine framework behind that answer, not just a shrug.
Start with your timeline
Google Ads can produce enquiries within days. SEO takes months to build, even when it’s done well. If you need revenue this quarter and can’t wait, Ads is the more realistic first move — SEO becomes the thing that reduces your reliance on paid spend over time, not the thing that saves this quarter.
Consider the actual cost per click in your category
Some categories — legal, finance, certain trades — have Ads costs per click well past $50. In categories that expensive, the mathematics of Ads only work for high-value transactions, and SEO’s fixed monthly cost regardless of volume becomes comparatively more attractive once you’re established. In cheaper categories, Ads can be efficient at almost any stage.
Think about compounding versus renting
SEO is closer to owning an asset — the rankings you build keep producing traffic without ongoing spend for each click (though they do require ongoing maintenance to hold). Google Ads is closer to renting — the moment you stop paying, the traffic stops. Neither is wrong, but they behave very differently over a two or three year horizon.
Look at your competitive set
If your organic competitors are thin and under-invested, SEO might move faster than you’d expect and be worth prioritising. If the Ads landscape in your category is uncompetitive (few bidders, low costs), Ads might be the more efficient near-term channel. These aren’t always correlated — a category can be easy to rank in and expensive to advertise in, or vice versa.
The honest answer for most businesses: both, sequenced deliberately
Most businesses that ask this question don’t actually need to choose one exclusively — they need to sequence the investment. Ads while SEO builds, with Ads data informing which SEO pages and terms to prioritise, is usually more efficient than picking one and ignoring the other entirely.
What we actually recommend
Run a smaller Ads budget from day one to start generating leads and data, while building the SEO foundation in parallel. Use the Ads performance data — which terms convert, which don’t — to prioritise the SEO content roadmap, rather than guessing at what to build first. This is a large part of why we run SEO and Ads together rather than as competing services.
