CONVERSION PROBLEM – EFFICIENCY

Hi
I am having the following issues: Why is CPA increasing even though traffic is unchanged?, Why are there many clicks but no customers?
Can discuss

Clicks and no buying customers
Or clicks and no registration

You gave little.information for a elaborate answer too

Your CPA is increasing because you're attracting low-intent clicks; fix it by auditing and shifting budget to your highest-quality traffic sources, tightening targeting with negative keywords, and ensuring your landing page directly matches your ad's promise to convert interest into purchases.
