How to restore deleted store tracking code for accurate sessions?

[HubertCumber]

We hired a developer from upwork to lower make our website speed score faster and he did this successfully but also removed the store session tracking code. 

Although our sales track accurately, the sessions are extremely inaccurate and are probably 5% of what they actually should be.

This means we have no idea what our CVR % is so we need an experienced developer to add the session tracking code back so that we have the real amount of sessions tracking.
