How can the segment 'Performed a search' bring that 50% of sessions used my site search?

Hello,

 

I am a bit confused about this.

 

I am trying to understand what % of my sessions performed a search and then clicked on something.

 

First I was looking at the general % of sessions that use site search. Say that with the 'All users' segment Analytics says that around 12% of sessions use site search. How is it possible that if I use the segment 'Performed a search' and I go to Reports > Site Search I get that 50% of sessions used the site search? Shouldn't this segment bring only sessions that used my search functionality therefore 100%?

 

Also, why the number of sessions with search (that 12%) doesn't match with the sessions that I get when I use the segment 'Performed a search'? 554K (all users >Site search) and 1,2M (Performed a search segment > Audience Overview) or even with the 'Performed site search segment' > Site Search report that shows 544K

 

I hope it makes sense. If not I can attach screenshots

 

Thanks and Best Regards, A.

Hi A,

 

Unless you have GA 360, you are getting sampled data.  Any segment, secondary dimension, or custom report over a date range that has more than 500k sessions (for most reports) will invoke user based sampling.   That is why you see a difference when segments are used vs not.

 

The data you seek is in site search overview.   In the scorecard, you'll see %search exits.  So if you have 20% then 80% did something after search.

 

Does that make sense?

 

Best,

Hi Theo,

 

Thanks for your reply. 

 

I found that the reason why my segments were not showing 100% of sessions having performed a search (Behaviour > Site Search) even though I had within the segment that they had entered a search term. It was because the default 'Performed search' segment from GA, and therefore the copies I created were based in users not sessions. When I changed the segments to include sessions instead of users, the percentage of sessions performing a searched moved from 50% to 100%. Does anyone know why the 'Performed search' is by default based in users by the way?

 

However, the number of sessions that performed a search (Behaviour >Site Search) still don't match even if I look at 2 days' worth of data which doesn't sample it so I am wondering if my segments are wrong?

 

I still can't figure out if my segments pick sessions that have performed a search why the number of sessions in Audience > Overview and Behaviour > Site Search don't match... Anyone can help, please?

 

Thanks and Kindest Regards, A.

Hi A,

 

Ahhh you were using the system segment.. got it.  Yes some are user and some are sessions, good thing to check -- the system segment also uses sequences and is based on search terms used in an attempt to clean up poor implementations - which is odd and probably unnecessary. 

If you've copied the system segment, that MAY explain the difference.

 

GA keeps a session level dimension on whether or not a search happened which is (inexplicably) different than the weird system segment.  Try this segment and see how your session counts look without sampling:

This uses the same criteria as the behavior report.

 

Hope that helps.
