We get asked this constantly, and the honest answer isn't which one is better. It's how much time you've got before you need results.
What each one is actually doing
Google Ads puts you in front of people the moment a campaign goes live. You pay per click, and when the budget runs out, so does the traffic. SEO is the opposite: nothing much happens for the first few weeks, but the ranking you build keeps sending visitors long after, without paying for each one.
A number worth knowing
Here's something we found digging into the actual search numbers for Cardiff: more people search for an SEO agency here every month than search for anything with "Google Ads" and "Cardiff" together. That doesn't mean nobody wants help running ads. It means people don't go looking for it locally the way they look for SEO — ads work tends to get set up through referral or nationally, not through a Cardiff-specific search. Worth remembering that what people type into Google and what they actually pay for aren't always the same list.
So which one should you start with?
- If you need enquiries in the next 4–6 weeks, start with Ads
- If you're building toward the next 12 months and want traffic that doesn't disappear the moment you pause spending, start with SEO
- If you can afford both, running Ads while SEO builds in the background is usually the strongest combination, not a compromise
Most businesses don't need to pick one forever. They need to know which one solves the problem they actually have right now.
