Google Ads vs Facebook Ads: which fills a service firm's pipeline faster?

Which is better for a service business, Google Ads or Facebook Ads?

Google Ads captures people already searching for your service, so it converts faster and suits urgent, high-intent work. Facebook Ads reaches people who were not searching yet, so it costs less per click but takes longer to convert. Most service firms should start with Google Ads, then add Facebook once tracking proves what a lead is worth.

That is the short answer. The longer answer is about how each platform earns its keep, because they are not competitors. They are two different jobs.

Google Ads: demand capture

When someone types "mortgage broker cromer" or "commercial lawyer sydney" into Google, they have a problem right now. Google Ads puts you in front of that person at the exact moment they are looking. Nothing else in marketing gets you closer to a signed client.

The trade-off is cost. Clicks on high-intent service keywords in Australia routinely cost $10 to $50 or more, because every competitor knows what that click is worth. You pay a premium for intent.

What that means in practice: Google Ads punishes waste brutally (our Google Ads management exists for exactly this reason). A leaky landing page, a slow follow-up, or a broad match keyword left unattended burns real money fast. When firms tell us "we tried Google Ads and it didn't work", the ads were rarely the problem. The system around them was.

Facebook Ads: demand creation

Most of your future clients are not searching for you today. They are vaguely aware their accountant never calls them back, or that their competitors seem busier. Facebook and Instagram ads reach those people during the scroll, plant the problem, and put your name on it.

Clicks are cheaper, often a fraction of Google's cost. But the person clicking was not looking for you, so conversion takes longer and depends heavily on creative quality and follow-up. Facebook leads that get a call within minutes convert. Facebook leads that wait a day mostly evaporate.

So which one first?

If you can only fund one channel, fund the one where buyers already exist. For almost every service firm, that is Google Ads on your core service and suburb keywords. It is the fastest route from ad spend to signed client, and it generates the conversion data that makes every later channel smarter.

That is the order we run for our own campaigns, and the order we build for clients. Add Facebook when one of these is true: your search volume is small enough that Google alone cannot fill capacity, you have proof assets worth showing (results, reviews, faces), or your cost per lead on Google has stabilised and you want cheaper volume on top.

The real answer is the boring one

The firms that win do not pick a side. They run both as one system: Google captures the people searching today, Facebook builds the queue of people who will search next quarter, and the same tracking, landing pages and instant follow-up sit under both. Every dollar gets measured against the same question: what did a client cost us from this channel?

That last part is the difference between marketing that compounds and marketing that just costs. If you cannot see cost per client by channel, you are not choosing between Google and Facebook. You are guessing between them.
