Remove the links from your footer that give credit to the theme authors... both links are dead and will cost you with SEO.
If you are going to use a pop-up email squeeze, put a delay on it... like 30 seconds. You are asking me to opt in and I haven't even had a look at your site. Better to get my interest a bit before starting to ask me for things.
Also do some research on how people read on the web. You want very short paragraphs, and scannable articles. Right now you just have a bunch of blocks of text, no one will read them.
