Each web page will have different elements that work for it. The “buy” button that converts best on one page can be very different than the one that works on another website.
Have a service that does specific page elements testing. You include a code in your page, and the service will transparently create multiple versions for the element you want to test, run the tests for you to determine the winning version. No work needed from you.
Many headlines templates are known to work well. It would be useful to learn from time to time which ones are the best.
Periodically, test the top headline formulas in different fields (health, money, self-help, golf, fitness, etc.) and publish a leaderboard of what works best for each field.
You want to know which headline template – from the many that are known to work – will work for your product and target audience.
A service that tests a lot of the best headline templates for your product and audience. You provide information about the product and accurate definition (demographic and psychographic) of your target audience, and the service will test the best headline templates to find the best of the best for you – in a short time.
It will be an advantage to know if the Swiss cross helps conversions.
Do a series of A/B tests using images that include the Swiss cross and images that do not. Logos with and without the Swiss cross, ad images, video overlays, etc. Tests should be done in different interest areas (consumer goods, services, online, retail, etc.)
When you write your post you try to make it the best you can. The best headline, best content structure, best images and videos, etc. But you don’t know if it’s the best you can do.
Create multiple versions of your blog post, test them all, publish the best, and sell the rest to other blogs. It’s more work but you will get the best performing post and get paid for doing all the extra work.
