Page interaction, through website chat, is a generally a good signal for SEO, provided it doesnt increase your page load times, doesnt cause problems with UX/navigation and someone on your side actually engages with those chat leads and not make them wait.

Pickup a chatbot which integrates well with your MA tool because I have seen chat lead attribution to be the biggest issue. If you use Hubspot, they have a chat tool but not sure how good it is.

Give Happyfox chat a look.
It's very flexible with a lot of good integrations to tap into your existing workflows

The only way a chatbot may help with SEO, is if it somehow reduced your pages bounce rate.
It's more likely to increase load times and affect negatively.

The only reason I would relate SEO and chatbots is if there are page son your website which are getting good organic traffic and the chatbot helps increase conversion rates. I.e. it's not helping with SEO but helping with converting organic search traffic.

This is very useful. 
Thank you everyone!
