Quick answer
Choose Google Ads when people already search for your service (clinics, repairs, rentals, coaching). Choose Meta Ads (Facebook and Instagram) when people discover what you sell by seeing it (fashion, food, real estate, offers, events). Many local businesses start with one, measure cost per lead, then add the other.
"Should I run Google Ads or Facebook ads?" is one of the most common questions we hear from business owners in Kanchipuram and Chennai. The honest answer is: it depends on how your customers decide to buy. This guide explains the difference simply.
The core difference
| Google Ads | Meta Ads (Facebook & Instagram) | |
|---|---|---|
| Who sees it | People actively searching for a service | People scrolling, chosen by location, age and interests |
| Buyer intent | High: they need it now | Lower: you create the interest |
| Best format | Text ads, call ads, Maps ads | Reels, images, carousels, lead forms |
| Strongest for | Urgent and planned services | Visual products, offers, launches |
| Typical goal | Calls and website enquiries | Leads, WhatsApp chats, awareness |
When Google Ads work best
Google Ads show when someone types a search. If people already look for what you sell, Google puts you in front of them at the exact moment they need you. Good fits include:
- Clinics and hospitals ("eye hospital Kanchipuram")
- Repairs and home services ("AC service near me")
- Rentals and events ("shamiyana rental Kanchipuram")
- Coaching and courses ("NEET coaching Chengalpattu")
- B2B services that buyers research
Use location targeting to show ads only within a set radius, and call extensions so people can phone you with one tap.
When Meta Ads work best
Meta Ads reach people who weren't searching, which makes them ideal when your product is something people want once they see it. Good fits include:
- Silk sarees, fashion and jewellery
- Restaurants, bakeries and sweets
- Real estate projects and plots
- Festival offers and shop launches
- Events, summits and workshops
Meta's instant lead forms are especially useful for local businesses: people submit their name and number without leaving Instagram or Facebook.
What a real campaign looks like
One Meta lead campaign we ran brought 98 leads at an average cost of ₹32.14 per lead, reaching 5,586 people. Two things made the difference:
- Weekly optimisation: we paused weak ads and moved budget to the best performers every week.
- Following the data: the 25 to 34 age group produced the most leads, so we shifted budget towards it.
Your numbers will depend on your industry, offer and area, but the method applies to every campaign: measure cost per lead, not clicks or likes.
How much should you spend?
For a local business, we usually recommend starting with ₹5,000 to ₹10,000 per month in ad spend, paid directly to Google or Meta. That is enough to collect data for two to four weeks and see your real cost per lead. Once you know a campaign works, increase the budget gradually.
Common mistakes to avoid
- Boosting posts instead of running proper campaigns from Ads Manager. Boosting gives little control over targeting and goals.
- Targeting all of Tamil Nadu when customers only come from 15 km around you.
- Sending ads to the home page instead of a focused landing page or WhatsApp.
- Not tracking calls and leads, so you can't tell which ads work.
- Stopping after a week. Campaigns need a few weeks to settle and improve.
Our recommendation
If people search for your service, start with Google Ads. If people buy what they see, start with Meta Ads. Run it for a month, measure cost per lead, then test the other platform. Most growing businesses end up using both: Meta to create demand, Google to capture it.
