Two important things that will immediately increase your conversion rate is
1. Site speed
2. Scroll based tests
SITE SPEED
About 60% of users bounce off your site if it takes more than 4 seconds to load
Start working towards a sweet spot of a 3 second load speed. I have a store that reaches over 5k people a day and the simplest way for conv increase was site speed
SCROLL BASED TESTS
Secondly, go to your google analytics and begin setting up events based off scroll.
If someone scrolls for e.x 25% of your page and the conv rate for people who scroll that 25% is 1.5%, compare that to the people who reach 50% of your page. This will allow you to see what is working, where are people bouncing off, what ist he winning selling point that is instigating the highest conversion rate. etc
