We are using views to track screens of our mobile application and action tracking for things like button presses etc.
I would like to make an analysis where users are only counted the first time they do a specific action/ visit a page. This would be especially useful for feature adoption analysis and similar.
See an example here:
You can see unique visitors per week for a specific page. I did break down the unique visitors per User-hash which is unique per user. You can see that 1 user shows up every week (red circle) as a unique visitor. Now I would like to adapt this analysis that every user only shows up in the week where he/she did visit the page the first time.
Event serialization would help with events, but if you're trying to see just the first time that a specific page is seen, you would have to be firing/serializing a custom event for each page that you want this metric for.
Instead, you can build a segment for each page/event that you're interested in seeing the first interaction. It would look something like this. Make sure to select "after sequence" (highlighted in red circle). Also, this segment will only show the first time that the page was viewed per visitor in your report timeframe. So if you want to see the absolute first time that the page has been viewed by each user, you'll need a very wide timeframe.
