These are not really alternatives. Ads buy visibility immediately and stop the moment you stop paying. SEO builds visibility slowly and keeps it. The right question is not which one, but which one first given your situation.
Google Ads: speed, at a price
Ads can generate enquiries within days. You control exactly which searches you appear for, you can test messaging quickly, and attribution is clean. The catch is that it is rented traffic — visibility ends with the budget, and in competitive industries the cost per enquiry can be uncomfortable.
- Best when: you need enquiries now, or are testing whether demand exists
- Costs: ongoing and permanent — there is no accumulated asset
SEO: slow, then durable
Organic visibility takes months to build and can persist for years. Cost per enquiry drops over time as the investment compounds. The catch is the lag — six to twelve months for competitive terms is normal, which is unhelpful if you need work this quarter.
- Best when: you can wait, and want a cost base that improves rather than repeats
- Costs: front-loaded, with the return arriving later
Why the order usually matters
For a business with no visibility and no immediate pipeline, ads first makes sense — they generate cashflow and, importantly, tell you which search terms actually convert. That data then makes the SEO investment far better targeted, because you are building pages for terms you have already proven produce customers rather than terms that merely have volume.
When ads are the wrong choice
If your average customer value is low and your industry has a high cost per click, ads may never work at any budget. Working out roughly what a customer is worth to you, before spending, is the step most businesses skip.
When SEO is the wrong choice
If you need enquiries this month, SEO will not deliver them. It is also poor value for genuinely one-off needs, or in markets so dominated by established competitors that realistic terms have negligible volume.
Frequently asked questions
Should I do SEO or Google Ads first?
Usually ads first if you need enquiries now — they also reveal which terms convert, which makes subsequent SEO far better targeted.
Is SEO cheaper than Google Ads?
Over a long enough period, usually. SEO costs are front-loaded and the return compounds; ad costs repeat forever.
How long before SEO works?
One to three months for low-competition local terms, six to twelve or more for competitive commercial terms.
Can I do both?
Most businesses should. Ads cover the gap while SEO builds, then ad spend can often be reduced as organic visibility takes over.
