Google Ads can put your business at the top of Google the same day you start. For a small business, that speed is valuable: a new clinic, a new branch or a seasonal offer can bring enquiries while SEO is still building.
It can also burn money fast if it is set up carelessly. This guide covers the basics that protect your budget.
How Google Ads works
You choose keywords that customers search, write ads and set a budget. When someone searches, Google runs an auction based on your bid and the quality of your ad and landing page. You pay when someone clicks (for search ads).
Good ads with relevant landing pages often pay less per click than poorly matched ones.
Campaign types for small businesses
Campaign type | Where ads show | Best for |
Search | Google search results | High-intent enquiries: “dentist in Coimbatore” |
Performance Max | Search, YouTube, Maps, Gmail, Display | Businesses with good conversion tracking |
Local / Maps placements | Google Maps and local results | Shops, clinics, restaurants |
Display | Websites and apps | Remarketing to past visitors |
YouTube | Video ads | Brand awareness, demonstrations |
Most small businesses should start with Search campaigns: they reach people actively looking for your service.
How much should you spend?
Work backwards from the value of a customer:
1. Estimate what a new customer is worth (first sale or lifetime value).
2. Decide what you can afford to pay for a customer.
3. Estimate how many enquiries become customers.
4. That tells you the maximum cost per enquiry you can accept.
Many local businesses test with a modest daily budget, such as a few hundred to a couple of thousand rupees a day, for four to six weeks, then scale what works. Cost per click varies widely by industry and competition. Use Google’s Keyword Planner to see estimates for your keywords.
Step-by-step setup
1. Pick tight keywords
Choose keywords that show buying intent and include your location or service:
• “physiotherapy clinic coimbatore”
• “ac service near me”
• “website development company in coimbatore”
Use phrase and exact match types to start. Broad match can work later, once conversion tracking is in place.
2. Add negative keywords
Block searches that waste money, such as “free”, “jobs”, “course”, “salary” or “DIY”. Review the search terms report weekly and add more.
3. Write specific ads
• Mention the service and location in the headline
• Include a clear benefit: same-day service, free consultation, starting price
• Add a call to action: “Book today”, “Call now”
• Use extensions: call, location, sitelinks and callouts
4. Send clicks to the right page
Never send all ads to your homepage. Send each ad group to the most relevant service page or a dedicated landing page with:
• A headline that matches the ad
• Clear offer and proof: reviews, photos, results
• A short form, click-to-call and WhatsApp button
• Fast loading on mobile
5. Track conversions
Without tracking, you are guessing. Track form submissions, calls from ads and the website, and WhatsApp clicks. Connect Google Ads with Google Analytics 4.
6. Set location and schedule
Target only the areas you serve. Show ads during hours when you can answer calls, unless you use online booking.
Common mistakes
• Sending all traffic to the homepage
• No negative keywords
• No conversion tracking
• Targeting all of India for a local service
• Letting the agency run ads in an account you do not own
• Judging results after one week
