I'd like to track how many people hit my website that might be logged into LinkedIn. Depending on the results, I might add an interactive LinkedIn section using their API.
I already have the Javascript logic to detect if they're logged in. My question is what is the best approach to log this result? Can Google Analytics do it with a custom variable or event detection?
I'd love to report on something like, "10,000 visits to my website, of which X number of visitors were logged into LinkedIn".
Any help would be appreciated!
