SEO and PPC both put you in front of people searching on Google — but they work very differently, cost very differently, and suit different moments in a business's life. This guide compares them honestly so you can decide where your next rupee should go, rather than following whoever shouted loudest in your inbox.
The core difference
PPC (pay-per-click) buys your way to the top of the results instantly — you pay each time someone clicks. SEO (search engine optimisation) earns your way there over time by making your site the most relevant, trustworthy answer — the clicks are then free.
One is renting attention; the other is owning an asset. Neither is universally better — they trade off speed against durability.
Speed: PPC wins
PPC can drive qualified traffic within hours of launching. That makes it ideal when you need results now — a product launch, a seasonal push, a new location, or simply testing whether a market responds before committing to a longer play.
SEO is a slow build. Expect months before it compounds. What you're buying with that patience is traffic that doesn't switch off when the budget does.
Cost over time: SEO wins
With PPC, your cost per lead is roughly flat — and often rises as competition bids up the auction. Stop paying and the traffic stops the same day.
With SEO, the cost is front-loaded: you invest before you see returns. But as rankings compound, your effective cost per lead falls, and a page that ranks keeps working for months or years after the work is done. Over a long enough horizon, organic is almost always the cheaper channel.
When to choose which
There's no universal answer, but these patterns hold for most businesses:
- Choose PPC first if you need leads immediately, are testing a new offer or market, or sell something high-margin where paid clicks pay back fast.
- Lean into SEO if you're building for the long term, operate in a content-rich space, or want to reduce dependence on ever-rising ad costs.
- Do both if you can: use PPC for immediate flow and to learn which keywords convert, then use that data to prioritise the SEO that makes those same clicks free over time.
Why the two work best together
SEO and PPC aren't rivals — they compound. PPC gives you fast conversion data that tells your SEO team exactly which terms are worth the multi-month investment. SEO, in turn, lowers your reliance on paid traffic so your ad budget can chase growth instead of just keeping the lights on. Owning both the paid and organic result for a key term also squeezes out competitors and lifts total clicks.
Frequently asked questions
Is SEO or PPC better for a small business?
If you need leads this month, start with a tightly-targeted PPC campaign — it's the fastest way to test demand. In parallel, invest in SEO so that over 6–12 months your cost per lead falls and you're not paying for every click forever. Most successful small businesses run a small amount of both.
Can I do SEO and PPC at the same time?
Yes, and it's usually the strongest approach. PPC delivers immediate traffic and conversion data; SEO builds durable, lower-cost traffic over time. Running both lets each inform the other — paid data guides your SEO priorities, and organic wins free up ad budget for growth.
Which is cheaper, SEO or PPC?
PPC is cheaper to start but costs the same (or more) per lead forever. SEO costs more upfront and takes time, but its cost per lead falls as rankings compound. Over the long run, SEO is typically the cheaper channel; over the first few weeks, PPC is.
