Can conversions be automated?

[frank]

In a perfect little world yes.

But in the real world its impossible. Since you asked whether it will generate constant income or not.

You created a great sales copy that generate leads easily that's great.

But your competitors saw it and they made one even betters. So, after sometime you will need to update the sales copy and not to mention it will happen to your landing page too.

Coming to ad campaigns. The bids of the advertiser changes constantly. And if you run a good campaign evn though you have to track and optimize ads in a regular basis.
