Increasing conversions of anything is usually a trial and error type of situation where you are consistently moving buttons and text in order to figure out exactly how things need to be positioned to work much more efficiently.

Here are a few ways to improve and increase website conversions:
Website Colors: If you want someone to click on a button try using different colors of the button and see how they respond. Sometimes changing the color is all you need for visitors to shift their eyeball over to that location.
De-Clutter: Is there too much distraction on your web pages? Are visitors wandering around or off the site with little to no direction? Try cleaning things up a bit. Remove text that doesn’t need to be there, get rid of those useless Google ads and if you have affiliate banners that have not generated any income for you in the last 12 months why on earth are they still there?
Sizes: If you are putting emphasis on your phone number increase the size of the text. Make the number or email much larger and prominent on your website so it stands out to your audience. The same goes with website buttons, make them big.
Business Messaging: What is the goal of your website? Is your business messaging coming across how it should and where it should? Your business message should be visible exactly where your audience’s eyes hit the page. It should also be clear and concise so a visitor does not need to figure out what you do. If they have to figure out what you do your website will ultimately fail.
Website Speed: Not many people think about this from a conversion stand point but think about your site speed. If your pages take quite a bit of time to load you might end up losing website visitors from frustration.
There are many factors that fall into place when it comes to website conversions and they all have to be working properly. Take the time to test out different efforts in order to see how they respond for you. Over time you will find the right position for everything to work properly.
