Meta Ads and Google Ads solve two different problems, not the same problem twice. Google Ads shows up when someone is already searching for what you sell — you're capturing demand that already exists. Meta Ads, on Facebook and Instagram, shows up while someone is scrolling, not searching — you're creating demand by reaching the right person before they've started looking. Neither is "better" in general. Which one wins depends entirely on what you're selling and how people usually decide to buy it.
The core difference: intent vs. interest
Google Ads is triggered by a keyword someone typed — it's intent-based. Meta Ads is triggered by who someone is and what they engage with — it's interest-based. That one distinction explains almost every other difference between the two platforms.
When Google Ads usually wins
- High-intent purchases people actively search for by name
- Local, "near me" service businesses
- B2B products with clear, specific search terms
- Anything with an established, searchable category
When Meta Ads usually wins
- Visual products — fashion, jewellery, home décor, food
- Impulse or discovery purchases nobody was actively searching for yet
- Brand awareness and building an audience from zero
- Retargeting people who visited but didn't buy
Rule of thumb: if the customer already knows the product category exists, start with Google. If you need to introduce them to it, start with Meta.
What about cost?
Both run on auctions, so cost varies by industry and competition rather than by platform. Google Ads clicks on competitive commercial terms tend to cost more, because the person clicking is often close to a purchase decision. Meta Ads clicks are frequently cheaper, but the ad's creative — image, video, copy — has to do more of the convincing, since nobody typed in a request for it.
Use both, differently
The strongest setups rarely pick one. Google Ads catches the people already looking. Meta Ads builds the audience that will search later, and brings back the ones who visited the site and left without buying. Run for Vibrant Biz Com Ltd's event, for example, close to 20 individual ad variations were needed before the right creative-and-audience combination clicked — that kind of iteration is normal on Meta, and rare on Google, where the keyword mostly does the targeting for you.
Keywords are still doing work behind the scenes on the Google side — see SEO Keywords, Explained for how to find and place them properly.
