Have you searched past threads? We've discussed this profusely, and there are various user-contributed and commercial JS libraries mentioned. (There's no one "best" way: you'll always need a JS component running on every page but the feature set of that client-side component and its back-end service, if it has one, will differ).)
Thanks for your response.
I looked at some of the previous messages regarding this topic but did not have much success. I would really appreciate if you can point me to the right thread(s).
You mentioned that there is no "best" way but can you suggest a way that can be done in Marketo that does not require any programming (JS component, etc).
