Depending on the level of ad blocking features customers have enabled on their browsers, you may not always be able to access key demographic information. This isn’t because your live chat tools are actually ads, but as of this writing, some ad-blocking tools see any pop-ups -- including chat windows -- as possible spam. Though this is uncommon, if it does happen, consider enabling a message on your website to visitors that instructs them to whitelist your page. Then, you’ll be able to see their customer data.
