I checked the website. Keyword cannibalization might be the reason. All the page titles contain Live Chat keyword. Even few pages ate stuffed with keywords
Eg: Live Chat Software | Live Support | Help Desk Software . You can see Live twice and Software twice. Instead of repeating the same words twice you can frame a phrase. A title should be a meaningful phrase instead of stuffing with keywords. Try Live chat support and help desk software. Here Live chat, live chat software, Live chat support, live chat support software, live chat Help desk, live chat help desk software all the keywords will be covered in the phrase.
