Google Ads or Meta Ads: where is your customer ready to buy?

“Should I advertise on Google or on Instagram?” This question comes up in almost every first conversation I have with a client. And the honest answer is: it depends on how your customer buys.

Both platforms work, but they work in different ways. Understanding that difference saves a lot of wasted money.

Google Ads: advertising to people who are already searching

On Google, people type what they want. They already have the problem and are actively looking for a solution: “dentist near me”, “AC repair”, “accountant for small business”. I call this buying by intent.

The big advantage is how warm the lead is. Someone who searches “employment lawyer in Miami” is much closer to hiring than someone who saw a law firm ad while scrolling their feed.

Google usually works very well for:

• Urgent or need-based services (plumber, towing, locksmith, clinic).
• Local businesses that people search for by service name plus city.
• B2B services that clients research before hiring.
• Products people already know they want and are just choosing where to buy.

The limit is that Google only reaches people who are already searching. If nobody searches for what you sell, no search ad will fix that.

Meta Ads: advertising to people who aren’t searching yet

Nobody opens Instagram or Facebook to buy something. People are looking at friends’ photos, videos, news. Your ad shows up in the middle of that. I call this buying by attention: you need to interrupt people and spark a desire they may not have known they had.

It sounds like a disadvantage, but that’s exactly Meta’s strength. It lets you create demand, not just capture the demand that already exists. It works very well for:

• Visual products and services (fashion, aesthetics, food, decor, real estate).
• New things people don’t know about yet and therefore don’t search for.
• Impulse offers and limited-time promotions.
• Remarketing: reaching people again who have already visited your website or engaged with your profile.

Google captures existing demand. Meta creates new demand. Together they close the loop.

How I decide where to start

Before setting a budget, I ask three questions about the business:

• Do people search for what you sell? If so, Google belongs in the strategy. You can check search volume with Google’s own Keyword Planner.
• Does your product catch the eye in a photo or video? If so, Meta has a lot of potential.
• How long does the customer take to decide? Quick purchases can work with a single ad. Long decisions need several touchpoints, and that’s where remarketing makes a difference.

For most of the local businesses I work with, the safest path is to start with the channel that captures existing demand and use the other to reinforce it: people who searched on Google and didn’t buy see your brand again on Instagram over the following days.

The most common mistake

The mistake I see most isn’t choosing the wrong platform. It’s judging both by the same yardstick. A Google lead is usually more expensive and warmer. A Meta lead is usually cheaper and needs more work from your sales team. If you only compare cost per lead, Meta will always look better. If you only compare close rate, Google will.

What matters is how much each sale costs on each channel. That’s the number that shows where to put more money.

In short

There’s no “best” platform. There’s the right platform for the moment your customer is in. Figure out whether they buy by intent or by attention, start with the channel that makes the most sense and measure both by the same thing: money in the bank.
