Google Ads Budget: How Much Should a Small Business Actually Spend?
Asking "how much should I spend on Google Ads" without knowing your numbers is like asking how much to spend on inventory without knowing your margins — the honest answer starts with your own math, not a rule of thumb.
Work backward from what a customer is worth to you
If a customer is worth ₹10,000 in profit over their lifetime, and you can profitably spend up to a third of that to acquire them, that gives you a real per-lead budget ceiling — a number ads platforms can't tell you, only your own business data can.
Cost-per-click varies enormously by industry and keyword competition
A real estate or legal services keyword in a competitive city can cost many times more per click than a niche product category — checking realistic CPC ranges for your specific keywords before setting a budget prevents an unrealistically small budget from getting exhausted in a day.
A too-small budget can actually be worse than no budget
Google's algorithm needs enough data (clicks and conversions) to optimize a campaign properly. A budget that's spread too thin across too many keywords often means the algorithm never gets enough signal to perform well, wasting spend rather than saving it.
Start narrow, then expand based on what's actually working
A smaller budget on your highest-intent keywords, running long enough to gather real conversion data, usually outperforms a broad launch across every relevant keyword from day one — expand once you know what's converting, not before.
