I run both Google Ads and Facebook ads for a living, so the question I get most from founders is simple: which one should I start with for leads? The honest answer is that they do two different jobs, and picking the wrong one first is how good budgets get wasted.
The real difference is intent
Google Search captures demand that already exists. Someone types “ship a car to Texas” or “auto parts for my model” and they are already looking for exactly what you sell. You are not talking anyone into wanting it. You are showing up at the moment they decided to buy.
Meta works the other way around. Nobody opens Facebook or Instagram to buy anything. You interrupt people who match your customer and create the interest on the spot. That one difference, existing demand versus created demand, drives everything else: lead quality, cost, and how long the sale takes to close.
Lead quality and the sales cycle
Google leads tend to arrive warmer because the person went looking. They are further along and closer to a decision. The catch is that they are usually comparing you to two or three competitors in the same search, so the lead is qualified but contested.
Meta leads arrive colder because you caught someone mid-scroll. Some are tire-kickers. But the volume is much higher and the top of your funnel fills fast, which matters a lot when your offer is easy to say yes to.
I have the numbers on both sides. On a US auto-transport account I ran on Meta, we brought in 5,599 leads at $2.68 each, and held that cost steady while scaling the budget. That is demand generation doing exactly what it should: cheap, high volume, a wide net for an offer people decide on quickly.
On a US accessories brand I ran on Google, the leads cost $91.18 each. 906 of them, high value, long sales cycle. On paper that number looks brutal next to $2.68. In practice those leads closed, because they came from people already searching for the product and the deal size covered the cost many times over.
Same word, “lead”, two completely different things.
Cost is only half the story
Cheap leads are not automatically better leads. The $2.68 auto-transport lead and the $91.18 accessories lead both made money, because the cost fit the offer behind it. A $2.68 lead is a bargain for a fast, low-ticket decision. A $91.18 lead is a bargain for a high-ticket product with a long cycle. Judge the cost against what the lead is worth, never on its own.
On budget, Google has a ceiling. You can only capture as much demand as people are actually searching for. Once you own the high-intent keywords, extra spend starts buying weaker terms. Meta has almost no ceiling on volume, but it needs a steady stream of fresh creative to keep working, because you are the one holding the attention.
Which one to start with
If people are already searching for what you sell, start with Google. You are collecting demand that exists today, and it is usually the shortest path to a lead that closes. Auto parts, legal help, “ship my car”, emergency services: Google first.
If demand for your thing is thin, or you are creating a new category, start with Meta. You cannot capture searches that are not happening, so you generate the interest instead. New products, impulse offers, anything visual: Meta first.
They work best together
The real gain shows up when you run both. Google Search tells you exactly which terms turn into real leads and sales, and that is buyer language proven with money. I feed those winning terms straight into Meta targeting and ad copy, and I feed Meta’s audience signals back into Google. Each channel sharpens the other, and the whole account gets more efficient than either one running alone.
Start with the one that matches your demand, prove it, then add the second to compound it.
