What is conversion tracking? How sites know you bought something.

Conversion tracking explained: how Indian websites tell ad platforms when you sign up or buy, what is shared back, and why it matters for privacy.

The simple answer

Conversion tracking is how a website tells an ad platform that an ad worked: you clicked, then signed up, bought or filled a form. A small pixel or tag fires at the success moment and reports it back.

This is useful for measuring ads, but it also means your key actions, like a purchase or signup, can become signals sent to advertising systems. The question is what is shared and whether it is disclosed.

What to check

1
Notice pixels firing on thank-you or success pages.

If this is unclear, treat it as a signal to ask the company for a plain-English explanation.

2
Look for conversion or pixel language in policies.
