If you have a limited ad budget, the choice between Google Ads and Facebook Ads (which includes Instagram) matters. Both can work well, but they work in different ways, and the right one depends on what you sell and how people buy it.
The key difference: intent
- Google Ads show your ad to people who are already searching for what you offer: “plumber near me”, “GST registration fees”, “buy running shoes online”. The demand exists; you are catching it.
- Facebook and Instagram Ads show your ad to people based on who they are and what they are interested in, while they scroll. Most are not looking for you at that moment; you are creating interest.
That one difference explains most of the rest.
When Google Ads is usually the better start
- People search for your service when they need it: repairs, legal and financial services, healthcare, home services, B2B services.
- The need is urgent: when something breaks, people search and call.
- Your service is hard to show in a picture, but easy to describe in words.
- You want enquiries quickly and can handle calls.
When Facebook and Instagram Ads are usually the better start
- Your product or service is visual: fashion, food, interiors, beauty, travel, events.
- People do not search for it, but buy it when they see it: new products, gifts, impulse buys.
- You can target a clear audience by location, age, interests or job.
- You want to build awareness or a following, then retarget those people.
Costs: what to expect
Google clicks are often more expensive, but each click comes from someone actively looking. Facebook clicks and impressions are usually cheaper, but more of those people are just browsing. Compare cost per enquiry or sale, not cost per click: a $3 Google click that becomes a customer beats ten $0.30 Facebook clicks that do not.
What both need to work
- Conversion tracking: GA4 and Google Ads conversions for Google, the Meta Pixel and Conversions API for Facebook. Without it, neither platform can learn who your customers are. See our GA4 Set Up and Meta Pixel and CAPI Set Up.
- A good landing page: a page for that offer with your phone, WhatsApp and a short form near the top.
- Time to learn: give a campaign at least two to four weeks before judging it.
Can you use both?
Yes, and many businesses should, once the first channel works. A common pattern: Google Ads brings people who are ready to buy; Facebook and Instagram retarget the people who visited but did not enquire, and build awareness so more people search for you later. Running both together, with one budget that follows results, is what our Performance Marketing plans do.
A simple way to decide
Ask yourself: when my customers need me, do they search for it? If yes, start with Google Ads. If they are more likely to buy after seeing it, start with Facebook and Instagram Ads. If you are not sure, ask for a free check and I will tell you which I would start with for your business, and why.
