Must Read: How To Improve Your Website's Bounce Rate
1. Do Not Use Auto Play - Audio & Video
I recommend using video and audio on your website, just don't have it auto play. There is nothing worst than landing on a website and some crazy music start to play, I have seen this many time and the first thing i do is I hit a back button. Someone in the work or in a place and they can't listen to the loud music or video, they will definitely hit the back button.
2. Treating Your Home Page Like A Squeeze Page
Is ok to have squeeze pages and landing pages if you are sending traffic directly to those pages. But if you are treating your home page like Hey get my free offer or buy my stuff, the visitor has two option and if they back out, that gonna increase your bounce rate. Do not treat your home page like a squeeze page or landing pages, your home page must be a channel to the rest of your site and you must optimize for the thought sequences.
3. Short Article
Always make sure your content is 500 words long, anything less than that is too short, having a very long article will make visitor spend more time to read your content and the longer they stay on your page the more they would you make you some cash. Even if you can't write a long article, just make sure to link to other pages so they can check other stuff you have on your website.
4. Your website is too Cluttarel
If you go to some website you see turn of crap all over the website like blinking ads, tons of content and images all over the place, you don't know where to focus. Don't make your website too Cluttare, give it a white space and make it easy for people to read.
5. Font Size:
You can't have your font size too small, I think 12.5 is the minimum and I still think that is too small, in some cases i go for 16.5 and that help improve the bounce rate on my site because the text is big in the eyes, and is more inviting to your visitor to read content with bigger fun.
6. Not using a Tag line on your header

7. No Headline
8. Too Many Option Offered
if there are too many offered, too many things and people don't know what to do when they get confused they will typically do nothing and hit the back button to leave your website.
9. Reverse Copy
You don't want a black background on your website with red text. You want a white background with black text, is always the best way to go.
10. Font Color
do not use red or blue font, make sure it black font on white background.
