For your convenience 10% conversion appears high so if you still aren’t profitable you’ll need to focus on improving Landing Page CTR, decreasing the cost of your traffic source through bidding or asking for a pay bump on your promoted offer.
To improve landing page CTR do the following:
Depends on the niche but a "good" Landing Page CTR can be as high as 30-50%
Overtime though CTR is not nearly as important as conversion rate.
In order to improve your CTR look at the following:
- Page speed (use free tools like GT metrix for this)
- Compress your images and use the least code possible (this makes wordpress or wix a no go)
- How similar your presale is to the offer page e.g. same colours and pictures so it "flows"
- Test multiple pre-sale pages and see which one performs best
- You can also look at Spy tools to click on ads and see which landing pages others are using
- Spelling mistakes and errors that make it lose credibility (this is very easy to do when translating languages)
