Any thoughts on using Salesforce for tracking customer success & adoption? Or is there a better thing out there?

You can consider ChurnZero or other specific CS softwares.

ChurnZero is focused on the onboarding and NPS-like stuff instead of deeper adoption and usage metrics. A lot of companies use product analytics tools like Amplitude/Mixpanel (for web applications) and Moesif for API products to track who got implemented today and their usage levels. The key item is getting your CRM to sync account/subscription info with the product analytics tool of choice. You can use third parties like Segment for this or many analytics tools already have plugins.

Any recommendations for tools to collect product usage data?

Has anyone used Google Analytics to track customer’s login pattern on the application portal? Is GA the best choice or is there any other free tools?

Anyone used google analytics to track customer’s usage of their platform? Any pointers on how/what to do? Is it as easy as simply embedding it in each page?

Any experience with customers requiring "Cyber Liability Insurance" and if AWS provides a "pass-through" Certificate of Insurance that their customers can use in customer development?

We are trying to tie up customer journey from Website to Web App. Both the sites have Google Analytics Tag (new GA4 tags) but we can't seem to figure out how to track the journey. Any pointers?
