SEO builds free, long-term organic traffic over a period of months, while PPC (Google Ads) delivers instant paid traffic you pay for per click. SEO is the lower long-term cost; PPC is the faster route to leads. Most businesses get the best results by combining the two.
The key difference
With SEO you earn rankings in the organic results and keep getting clicks without paying for each one — but it takes time to build. With PPC / Google Ads you bid to appear at the top instantly, but the traffic stops the moment you stop paying.
SEO vs PPC at a glance
- Speed: PPC = days. SEO = 3–6 months to build momentum.
- Cost over time: SEO’s cost per lead falls as you rank; PPC stays pay-per-click.
- Longevity: SEO results compound and persist; PPC stops when the budget does.
- Control: PPC offers precise targeting and instant testing; SEO builds lasting authority and trust.
When to choose which
Choose PPC when you need leads now, are launching, or testing a new offer. Choose SEO when you want sustainable, lower-cost growth. In practice the smartest approach is usually both: PPC for immediate enquiries while SEO builds the long-term foundation. Not sure on budget? Our SEO cost guide helps.
