Hi,
My name is Elad, and i have over 7 years of experience in online marketing based on ROI via Google Adwords & FB ads in many industries.
for all the clients that i work for them ever i used Google analytics & GTM to track and understand the data comes from & analyze the user behavior to maximize business goals,website funnel & ads funnel.
Also in the last few years i'm using heatmaps & recording sessions, by doing this, i can get fully understand how the user act into the site & make smart decisions from that to increase conversion rate & revenue for my clients.
i have consulting to many clients on A\B testing, copy & design to increase conversion rate, and it is work most of the time.
if you need to gain more leads & sales in the same ads spent, maybe i can help you.
Thanks,
Elad Isachani
