How to calculate conversion rate
Conversion rate is conversions divided by clicks, as a percentage. Forty conversions from 1,250 clicks is 3.2%. It is the measure of what happens after the click — whether the page delivers what the ad promised, and whether the offer is worth acting on.
It is also the highest-leverage number in most accounts. Cost per click is set by an auction you share with competitors. Conversion rate is set by your own page, and it is entirely yours to improve.
The conversion rate formula
Conversion rate = (conversions ÷ clicks) × 100. Use clicks for advertising and sessions for site-wide analytics, and never mix them in the same comparison: the two are counted differently and the gap will look like a change that never happened.
Be equally careful about what counts as a conversion. Counting newsletter sign-ups alongside purchases produces a flattering number that no one can act on. Measure the action that makes money, and track the rest separately.
A campaign records 40 conversions from 1,250 clicks, on ₹2,50,000 of spend:
(40 ÷ 1,250) × 100 = 3.2% conversion rate, at ₹6,250 per conversion. Lift the page to 4.5% and the same spend buys 56 conversions at ₹4,464.
What is a good conversion rate?
The Google Search average is about 3.75%, which is a reasonable reference point and a poor target. Ecommerce typically runs lower because a purchase asks more of a visitor; lead generation often runs higher because a form asks less.
- Match the page to the ad. A visitor who clicked a specific promise and lands on a homepage has to start again.
- Ask for less. Every optional field on a form costs you conversions in exchange for data nobody reads.
- Answer the obvious objection on the page: price, delivery, returns, or who else trusts you.
- Fix the phone experience first — it is usually most of the traffic and least of the conversions.
Conversion rate benchmarks
What counts as good depends mostly on what you are asking for. A high-value considered purchase converting at 1% may be a better business than a low-value impulse buy converting at 6%.
| Type | Typical range | Main constraint |
|---|---|---|
| Ecommerce | 1–3% | Price, delivery and trust |
| Lead generation | 3–8% | Form length and offer clarity |
| High-value B2B | Under 2% | Long consideration cycle |
How to improve conversion rate
Change one thing at a time and give it enough traffic to mean something. A test that moves from 3.2% to 3.5% on ninety visitors has told you nothing; the same result across several thousand is worth acting on.
The reliable wins are dull and repeatable: message match between ad and page, fewer form fields, faster loading on mobile, and the objection answered before it is asked. If traffic quality is good and the page is still not converting, the page is the bottleneck and more budget will only buy more of the same — which is when a conversion-focused review is worth more than a bid change.
