What should be my Bidding Strategy for Google Ads? (This is my 1st campaign!)

[Shubham-Marketer]

Which of the following Bidding Strategy is preferred when starting out on a Google Ads Search ads campaign?

1. Conversions/ Clicks ( With a manual value)

2. MAXIMISED conversions/clicks

3. Manual CPC

Also how to decide on the value of the approximate daily budget to use? ( For example if the commission is $170)

Thanks a lot!
