Google Ads vs Facebook Ads: Which Is Better?

Google Ads reaches people who are already looking for what you sell. Facebook and Instagram ads reach people who fit a profile but were not looking. That single difference drives every other difference between them.

Side by side

The mistake that wastes the most money

Comparing cost per click. Facebook clicks are cheaper and that number is nearly meaningless on its own. What matters is cost per customer, and search frequently wins there despite costing several times more per click — because the person was already trying to buy.

Which one should you start with?

Start with Google if people search for what you sell: emergency services, professional services, repairs, anything with a clear name someone would type. If there is existing demand, capturing it beats creating it.

Start with Facebook or Instagram if people do not know your category exists, or the product is visual and impulse-friendly. If nobody is searching, there is nothing for search ads to capture.

Run both once each is working alone. Retargeting on social to people who visited from search is one of the cheapest tactics available, because they already know you.

Budget reality

In expensive lead-gen categories a Google click can run $20 to $50, so a budget under roughly $1,500 a month collects data too slowly to optimise. Social clicks are cheaper, so smaller budgets go further — but a smaller budget on lower intent can simply mean buying more of the wrong people faster.
