How Much Should You Spend on Google Ads for Ecommerce in India?
A simple way to work out a Google Ads budget in rupees from your target orders, conversion rate and cost per click, with a worked example.
Start with a goal, not a number
Asking how much to spend on Google Ads is like asking how much fuel to buy without a destination. Decide how many orders you want, then work out what it takes to get them.
The simple formula
Check that the math can be profitable
Divide your budget by the orders. In the example, ₹22,500 ÷ 30 = ₹750 per order. If the average order brings less margin than that, the campaign loses money at this price and conversion rate. Improve conversion, raise order value or choose products with better margins before increasing spend.
How Google spends your daily budget
Your daily budget is an average. On some days Google may spend more and on others less, but over a month the total should stay within a limit tied to your daily figure. Check Google's help centre for the current rules.
How to split the budget
| Campaign | Typical priority |
|---|---|
| Brand search | Small, steady amount to protect your name |
| Shopping or Performance Max | Largest share, for your best products |
| Non-brand Search | Test with clear keywords and negatives |
When to raise the budget
- Your cost per purchase and return are healthy over several weeks.
- Your campaigns are limited by budget and still profitable.
- Your feed and tracking are clean.
