Okay, I'll start one by one* The first thing user sees on the website is an ad place. We have a habit of reading from left to right. Seeing ad at first will drive visitors away
* When we hit 'Calculate' which we should not as already stated, the whole page reloads. Even the footer and ad ig gone for micro seconds. The site should only refresh the price not page
* Make things bigger and ad smaller
* too much empty place between title and price form
* Reloading the tab manually gives
THIS which is annoying
* Make things look soft. Hard edges will scare people away. Look at preev, it's psychology
* Never think of placing the ad above 'form'
* place a small ad under it, make sure to add some padding between them
* Fix the ssl. See
THIS and
THIS* Price in title would be nice. People don't actually have to keep loading your page that way or even open it
* "Last Bitcoin Price" seems misleading. In fact the domain name is misleading. Google will index it some other way and probably won't show in first page which is what you should aim for.
* Change the domain name to .com. People love simply pressing ctrl + enter after the name. People don't even like .net or .org even though they have a shortcut too.
