This article talks about converting your entire website into a Dialogflow FAQ chatbot. If you are just interested in how to add a Dialogflow chatbot to your WordPress website, check out my course on the 7 ways to integrate Dialogflow into your WordPress website.
I have created a tool which allows you to turn your WordPress website into a Dialogflow FAQ chatbot for your website within a few minutes. It is based on the Dialogflow Messenger integration.
You can interact with the live bot (created by using this tool) here.
For now, the tool is free.
At some point in the future, I will probably make this a paid tool. So if you are interested, you should check it out soon.
