Google Analytics Troubleshooting

Job ID: 32443665

Budget: €30 – €250 EUR

We are looking for someone who can look into GTM Settings, GA Report and analyse those insight to answer for the question: "Where does direct traffic in GA come from?"
Our website hat more than 30% of traffic comes directly to our website. While looking into other dimensions to have a better understanding of this group, we found something: Most of this traffic lands on the known site, like Sign-In and Sign-Up page, which we think the number don't correspond with the actual visitor. Some of them come to a "(not set)" page. We think all of these can due to the fact that, there are error/probleme in our GA Settings.
If you are already have experienced with this task, or have an ideas of solutions for this project, please make some suggestion under with your budget and I would contact you as soon as possible. Thank you.
