Chatbots are a feature that enables you to provide customer service on your website without being online or present, especially as more and more browsers want businesses and services available 24 hours a day. Simple requests can be fulfilled, such as if a customer is looking for the best way to contact you.
Of course, when you are back in the office, you can provide a manned customer support messaging system. Services such a Zendesk, Jivochat and even Facebook Messenger can be integrated into your site for customers looking for more information and help.
As with all web design elements, always check to see if your live chat / chat bot has a negative effect on your page speed. As mentioned in the fast loading times section, having a slow website and page loading times can affect your search engine rankings.
