If you already have at least one page on Google that ranks in the top 10, you can increase your organic CTR by up to 5 times. The key is in A/B testing your headline.
But how can you do that without getting banned by Google for having dynamic headlines and without having to wait forever to try each different version?
This is how:
1. Use Google AdWords to make ads for no more than $50.
2. Test your headlines with A and B.
3. Find out who won.
4. Change your old title.
