Every business owner eventually asks this question: should I invest in SEO or PPC? The honest answer is that it depends on your situation, your timeline, and what you are trying to achieve. Anyone who tells you one is always better than the other is trying to sell you something.
This guide gives you a genuine, unbiased comparison so you can make the right decision for your business.
How they actually work
SEO (Search Engine Optimisation) is the process of earning your place in Google's organic results. You create content, optimise your website, and build credibility over time. You do not pay Google directly for clicks. The investment goes into content, tools, and expertise.
PPC (Pay Per Click) is Google Ads. You bid on keywords, write ad copy, and pay every time someone clicks. Your ad appears immediately at the top of search results, but the moment you stop paying, the traffic stops.
When PPC makes sense
PPC is not the enemy of SEO. It is genuinely the better choice in certain situations:
- You need results immediately. Launching a new product, running a seasonal promotion, or testing a new market. PPC delivers traffic from day one.
- You are testing keyword viability. Before investing months in SEO content for a keyword, run a PPC campaign to see if it actually converts. This is one of the smartest uses of paid search.
- Highly competitive keywords. Some keywords are dominated by large brands with massive domain authority. PPC lets you compete immediately while your organic presence builds.
- Time-sensitive offers. If you are running a limited-time deal, SEO will not help. You need visibility now.
When SEO wins
For most businesses with a long-term view, SEO delivers better returns over time. Here is why:
- Compounding returns. A blog post you publish today can drive traffic for years. A PPC ad drives traffic only while you are paying. SEO builds an asset. PPC is a tap you turn on and off.
- Lower cost per acquisition over time. SEO has higher upfront costs, but the cost per click is effectively zero once you rank. Most businesses see organic CPA drop below paid CPA within 12 to 18 months.
- Higher trust. Studies consistently show that users trust organic results more than ads. Click-through rates for the top organic result are typically three to five times higher than the top ad.
- Broader keyword coverage. PPC campaigns target specific keywords. A well-optimised website naturally ranks for hundreds or thousands of variations you never specifically targeted.
The ideal combination
The smartest businesses use both, but strategically. Here is the approach that delivers the best results:
- Use PPC for immediate visibility on your highest-value keywords while SEO builds momentum.
- As organic rankings improve, reduce PPC spend on keywords where you rank in the top three. Redirect that budget to keywords where you are not yet competitive organically.
- Use PPC data to inform SEO strategy. Your highest-converting PPC keywords should be your top SEO priorities.
- Keep PPC running on branded terms to prevent competitors from bidding on your name.
How to attribute revenue to each channel
This is where most businesses get confused. Without proper tracking, you end up double-counting conversions or giving all the credit to the last click.
At minimum, you need Google Analytics set up with conversion tracking and UTM parameters on all paid campaigns. This lets you see exactly how much revenue comes from organic versus paid search. Korvex takes this further by tracking revenue attribution daily and showing you cost per acquisition by channel, so you always know where your money works hardest.
The bottom line: PPC gives you speed. SEO gives you sustainability. The best strategy uses both, shifts budget as organic momentum builds, and measures everything by revenue rather than vanity metrics. Whichever you choose, make sure you can answer one question: how much revenue did this channel generate this month?
