This is the most common strategy question we get from new clients, and the honest answer is frustrating: it genuinely depends on your situation. But there are clear decision frameworks that make the answer obvious for most businesses.
The fundamental difference
Google Ads is rented visibility. You pay per click, and the moment you stop paying, you disappear. SEO is owned visibility — it takes 6–18 months to build, but once you're ranking, traffic arrives at no marginal cost. The strategic question is which makes more sense given your timeline, budget, and competitive landscape.
Google Ads: results in days, cost per click $2–$200+, stops when you stop paying
SEO: results in 6–18 months, no per-click cost, compounds over time
Combined: highest total reach, requires budget for both channels
Choose Google Ads first if:
- You need leads within 30–60 days (new business, seasonal campaign, cash flow need)
- You're entering a new market and need immediate presence while SEO builds
- Your customer lifetime value is high enough to support expensive CPCs profitably
- You're testing which keywords convert before investing in SEO content for them
- You have a specific product launch or time-sensitive promotion
Choose SEO first if:
- Your CPCs are so high that paid is barely profitable (especially true in legal, finance, insurance)
- You have a 12–24 month horizon and are thinking about compounding returns
- You want to build an asset that has value even if you reduce marketing spend later
- Your competitors have weak organic presence (check their domain authority)
- Your business is fundamentally discovery-driven — customers search before they know which company to use
The case for running both
For most established businesses with a meaningful marketing budget (£3,000+/month), the right answer is both — with different roles assigned to each channel.
Use Google Ads for immediate lead generation on your highest-value, most competitive keywords. Use SEO to build long-term rankings on those same keywords — reducing your paid dependency over time. As organic rankings improve, reduce paid spend on those terms and redirect budget to new keyword clusters.
This is the 'pay to rent while you build to own' strategy. It's more expensive in year one, but by year two or three, your cost per lead from organic is a fraction of what you started with.
The keywords-first approach
One practical way to decide: run Google Ads first on your target keywords for 60–90 days. This tells you which keywords actually convert (not just drive traffic) before you invest in SEO content for them. You'll know your conversion rate, cost per lead, and which queries bring buyers versus browsers.
Then build your SEO strategy around the keywords that converted — you've already validated them with real spend.
