A free 90-day campaign checklist (GA4-ready).
Why Google Ads for Service Businesses?
High-intent leads: People searching for “plumber near me” or “Colombo dentist” are already ready to buy.
Scalable results: Start small and scale with proven numbers.
Trackable ROI: With GA4, you know exactly which ad led to which client.
Google Ads is not guesswork, it’s math + messaging. That’s why the 90-day plan works so well.
The 90-Day ROI Blueprint
Phase 1 (Days 1–30): Foundation & Search Campaigns
Set up campaigns: Focus only on Search Ads (not Display/Video yet).
Keyword framework:
High-intent: “dentist Colombo,” “emergency plumber Sri Lanka.”
Service + location: “interior design Galle,” “tutoring Colombo.”
Long-tail: “affordable digital marketing Sri Lanka.”
Execution:
Create separate ad groups per service.
Write 3 ad variations per group.
Link ads to service-specific landing pages.
Budget guideline: Start with USD 7 – 15/day depending on industry.
Pro Tip: Don’t target too broad. Start with exact-match + phrase keywords to avoid wasted spend.
Phase 2 (Days 31–60): Remarketing & Trust Building
Many people won’t convert on first click.
Set up remarketing campaigns:
Display Ads: Show banners to website visitors.
YouTube Shorts Ads: Retarget with educational content.
Discovery Ads: Appear across Gmail/YouTube feeds.
Execution:
Create remarketing audiences (website visitors, form openers, non-converters).
Serve ads with trust-building content (testimonials, case studies, offers).
Keep budget small (10–20% of main spend).
Pro Tip: Retarget people with a lead magnet like a free guide or checklist.
Phase 3 (Days 61–90): Lead Nurture & Optimization
Now you’ll have traffic + remarketing audiences.
Add lead nurture flows:
Form → Email/WhatsApp follow-up.
Share service benefits, case studies, and appointment reminders.
Execution:
Connect GA4 to Google Ads (conversion tracking).
Track key actions: form submissions, WhatsApp clicks, calls.
Double down on ads with lowest Cost Per Lead (CPL).
Scale budget on winning campaigns by +20–30%.
Pro Tip: Review search term reports weekly, pause irrelevant keywords.
Conversion Tracking with GA4 (The Secret Sauce)
Without proper tracking, you’re flying blind. Here’s how to fix that:
Set up GA4 on your website.
Mark conversions: form submits, call button clicks, WhatsApp chats.
Import conversions into Google Ads.
Optimize campaigns for “Maximize Conversions.”
With this, every $ you spend can be tied back to a lead.
Funnel Structure Recap
Search Campaigns → Capture high-intent buyers.

This funnel ensures you don’t waste budget and every visitor has a path to becoming a client.
