I just installed (Crisp Chat)[https://crisp.chat/en/] and it has opened the door in so many ways within the first hour. I just got smacked in the face with the value of having a chat widget and don't know why I wasn't on it earlier. I could have increased sales most likely.
There is a certain point at which it becomes valuable. Just starting out there is no reason to add it. It doesn't become that valuable until you're getting around roughly 100 people to your site per day and trying to learn more about those visitors/offer premium support.
I just installed Crisp about an hour ago, and I have already been able to learn where some of the visitors are coming from and what issues they're facing.
I have an amazing customer I frequently talk to and get most product feedback/bugs from him. He just brought a bug to my attention today, then this user from the chat widget brought up the same bug within the past hour.
The feature that has an issue has been in production for over a month. So I assume many people encountered this and dropped off because of it, without me knowing.
I was also able to learn this person came from YouTube, which is crazy. I never would have thought YouTube would actually bring traffic.
Moral of the story if you're getting a little traction but are lacking transparency then install a chat widget. The thing that held me back was being scared to constantly be blown up, but forget that noise, just do it.
