An effective landing page is one where you have a clear call to action. There is one goal, one reason why a visitor is on that page.
Because of the focused goal, it is clear to your page’s visitor what it is they should do while there.
This focused goal helps to achieve your desired result, which in this case is gaining a lead or making a sell.
Review your page, determine how many CTAs you have, and eliminate the lower priority CTAs.
Look at your landing page. How many different links are there? If possible, reduce them.
