Ask Do Google Ads pay per click or conversion?

[cindy66]

My aim is to make maximum return on investment for every advert budget I have for a campaign. I've been reading Google Ads for a while now, but I'm still a bit confused about how take advantage of payment structure. Do Google Ads charge you per click or per conversion and how do you go about it? I know that with Cost-Per-Click (CPC), you pay when someone clicks on your ad, but I've heard that with Conversion-based bidding, you pay when a user completes a specific action, to be honest i sm bit confused with whole thing. Can anyone explain how these two work in practice and if one is better than the other for different types of campaigns? I will be looking forward to your response
