Google Ads or Facebook Ads first?

This is the question I get most often from brands about to spend their first real money on advertising. Usually phrased as which one is cheaper, or which one works better.

Neither has an answer. They are not competing versions of the same thing.

What most people think

That the two are interchangeable channels, and the job is to pick the one with the better return. So the decision gets made on whichever a friend had luck with, or whichever produced a lower cost per click in someone's screenshot.

What actually happens

Google captures demand that already exists. Somebody has a problem, types it into a search box, and you appear. The intent is not yours — you are intercepting it.

Facebook creates demand among people who were not looking. Nobody opens Instagram intending to buy. The ad has to do the work of making them want something they were not thinking about a second earlier.

Those are different jobs, and they fail differently. Google fails when nobody is searching for what you sell — you can have a perfect account and no volume, because the demand is not there to capture. Facebook fails when the creative does not earn attention, and no amount of budget fixes an ad nobody wants to watch.

Comparing their cost per click tells you almost nothing, because the clicks are not the same kind of click.

Why the gap exists

The channels get compared because the dashboards look similar. Both report spend, clicks and conversions in the same shape, which makes the numbers feel like they belong on the same axis.

They do not. One number is the price of meeting existing intent; the other is the price of manufacturing it. Putting them side by side is how a brand ends up scaling the cheaper channel and wondering why revenue did not follow.

How I actually decide

Start with one question: does anyone search for what you sell? Not your brand name — the problem. If people are typing it, Google first. That demand exists whether or not you show up, and capturing it is nearly always cheaper than creating it.

If the category is one people do not know to search for, Facebook first. New products, impulse purchases, anything visual, anything where the buyer would not know what phrase to type. You have to interrupt, which means the creative carries the whole thing.

For a local service, Google usually wins the first rupee. Somebody searching "FPV drone build service in Chennai" is closer to buying than anyone who can be found by interest targeting. I know this one from my own brand rather than a client's — Drixft's search traffic converts differently from its social traffic, and that gap is the reason I keep testing there first.

Whatever you pick, do not split a small budget across both. Two half-funded channels learn nothing. Each platform needs enough conversions to get out of its own learning phase, and a budget divided is usually a budget below that threshold on both sides.

Where this stops working

• Brand-term search. Bidding on your own name looks like the cheapest thing in the account. Much of it is people who would have found you anyway, so the return is real on the dashboard and imaginary in the business.
• Very small budgets. Below a certain spend the answer is neither. Fix the offer and the organic proof first; advertising multiplies what is already there rather than substituting for it.
• Businesses that cannot measure. If nobody can say what a customer is worth after returns and costs, both channels will look ambiguous no matter which you choose.

The takeaway

Pick the one that matches how people find what you sell, then give it enough budget to learn. Running both badly is the most common and most expensive version of this decision.

Once one is working, the second becomes a genuinely different question — and that is the point at which running them together starts to pay. How I structure and judge both is on my Facebook and Google Ads work page.
