Late Friday evening I moved over one of our sites to using Experience Cloud ID Service. For those that aren't aware this whilst dropping a first party cookie also drops a third party demdex cookie and thus allows for cross site de-duplication of visitors (if browser accepts a third party cookie). Based on 2 days worth of data, the results are very encouraging with various metrics showing improvements (and hopefully corrections) in line with issue of cookies being deleted mid visit.

1. No. of Visitors with no referrer has dropped significantly

2. Page Views per visitor has increased

On this basis I plan to roll this out across all our sites.... Not sure why Adobe is not recommending this to customers still using third party cookies.

I'd summarise 'our' steps as follows. Your may differ depending on your implementation.

1. Requirements for the Experience Cloud ID Service
2. If you're updating to AppMeasurement code from H code, check/update your plugins code as some are incompatible or will need updating. AppMeasurement Plug-in Support
3. If you have multiple instances of javascript code across your properties that won't be updating at the same time discuss Grace Period with Client Care. The ID Service Grace Period

Hope that helps.
