Both SEO and Google Ads put your business in front of people searching on Google. But they work very differently, cost money in different ways and suit different situations. Here's how to decide where your budget should go.
How they differ
| SEO | Google Ads | |
|---|---|---|
| Cost model | Monthly investment in work | Pay for every click |
| Speed | Months to build | Traffic from day one |
| When you stop | Traffic continues for a while | Traffic stops immediately |
| Trust | Many users trust organic results more | Clearly labelled as "Sponsored" |
| Control | Indirect, Google decides | Direct, you choose keywords and ads |
| Best for | Long-term, steady growth | Quick wins, testing, seasonal offers |
When Google Ads makes more sense
- You need leads this month. A new business or a new service can't wait six months.
- You're testing demand. Ads tell you quickly which keywords actually convert before you invest in content.
- Seasonal offers. Avurudu sales, December tourist season, back-to-school periods.
- Very competitive keywords where organic results are dominated by big platforms.
Click costs in Sri Lanka are often lower than in Western markets, which makes testing affordable. But in competitive niches like education, insurance or tourism, they add up quickly.
When SEO makes more sense
- You plan to be around for years. SEO builds an asset that keeps paying.
- Your customers research before buying. Guides, comparisons and FAQs rank in organic results, not ads.
- Local searches. The Google Maps pack is mostly organic, and ranking there is about local SEO.
- Your ad costs are climbing. Every organic click is one you don't pay for.
The cost over time
Ads have a flat cost curve: every month costs roughly the same for the same traffic. SEO is front-loaded: you invest more effort early, and the cost per visitor falls as rankings grow.
A business spending LKR 100,000 a month on ads gets roughly the same traffic in month 12 as in month 1. The same budget in SEO typically delivers little in month 1 but much more by month 12, and keeps delivering if spending drops.
Using both together
The strongest approach for most businesses is to combine them:
- Use ads to find what converts. Run ads on a range of keywords for a month or two.
- Invest SEO effort in the winners. Build strong pages for the keywords that brought paying customers.
- Reduce ad spend on keywords where you now rank organically.
- Keep ads for new offers, competitive terms and peak seasons.
Search Console and Google Ads data together, linked in GA4, show exactly where each channel is pulling its weight.
A common mistake
Many businesses run ads to a weak homepage. The ad gets the click, but the page doesn't convert. Whatever you choose, the landing page matters. The same work that makes a page rank, such as clear content, fast loading and an obvious next step, also makes ads cheaper, because Google rewards relevant landing pages with a better Quality Score.
Our recommendation
If you have budget for only one and you need customers now, start with ads while you fix the basics of your site. If you can wait a few months, or you serve a local area, SEO usually delivers better value over a year.
