Google Ads vs Meta vs TikTok: where each one actually wins

The honest answer to "which platform should I use" is that they do different jobs, and the mistake is treating them as interchangeable places to put budget.

Here's how I decide.

The core distinction: harvesting vs creating demand

Google Search harvests demand that already exists. Someone types "emergency plumber Cape Town". They have the problem, they want it solved now, and your job is to be there and be credible.

Meta and TikTok create demand. Nobody opens TikTok looking for your product. Your job is to interrupt convincingly enough that they develop intent they didn't arrive with.

This single distinction explains most platform decisions.

Google Ads

Wins when: people search for what you sell. Established categories, urgent needs, local services, replacement purchases, B2B where the buyer is actively researching.

Struggles when: nobody's searching. If you've invented a category or your product solves a problem people haven't named yet, search volume won't exist.

The economics: high intent means high conversion rates and high competition. Cost per click is often brutal; cost per acquisition is often still the best available.

Where accounts go wrong: poor negative keyword management, letting Performance Max cannibalise branded search and then crediting it with sales that were already coming, and running Search Partners or Display without noticing.

Meta Ads

Wins when: the product is visually demonstrable, the purchase is somewhat impulsive or considered-but-emotional, and you have a decent creative pipeline. Strong for e-commerce, coaching, local services with a visual result, and anything with a clear before/after.

Struggles when: the product needs explanation, the buying committee is large, or the sales cycle runs months.

The economics: cheaper attention, lower intent. You're paying less per click and converting a smaller share.

The thing that actually determines performance: creative volume. Not lookalike percentages, not detailed interest stacking. How many genuinely different angles you test per month.

TikTok Ads

Wins when: you can make native content. Younger audience, impulse-friendly price points, products with an obvious visual hook or demonstration.

Struggles when: your creative looks like an ad. TikTok punishes polish. A well-produced brand film will underperform a phone-shot demo consistently.

The economics: the cheapest attention of the three, with the shortest creative shelf life. Concepts fatigue in weeks.

The trap: repurposing Meta creative directly. What transfers is the offer and the hook logic. What doesn't is the format, pacing and tone.

How I'd sequence them

If you're starting and budget is limited: Google Search first, if search volume exists for what you sell. It's the fastest route to knowing whether the offer converts, because intent does half the work.

If no search volume exists: Meta first. Establish that people want the thing before you worry about scale.

Once one channel is profitable and stable: add a second. Not before. Splitting a small budget across three platforms gives all three too little data to optimise on.

TikTok: add when you have a creative process that can feed it, not before. It's the most creative-hungry of the three.

What actually decides it

Three questions, in order:

1. Is anyone searching for this? If yes, Google is probably first.
2. Can I produce creative consistently? If no, Meta and TikTok will disappoint you regardless of targeting.
3. Can my tracking tell these channels apart? If no, fix that first — see why your conversion tracking is probably wrong.

The platform matters far less than the offer, the creative, and whether you can measure what happened.
