I am building a web analytics application for search engine traffic only and right now I am looking into providing some information about keywords that Google does not show. Like not provided keyword.
I know that Google will not send you the keyword if the user did a secure search (SSL), but if the search is non-SSL, it should send it with all the parameters.
So I have a referral coming from Google that is HTTP, not HTTPS, it does send some parameters, but it leaves the keyword parameter
This is the example:
As you see there's no keyword in the
q parameter, anyone knows what kind of search is this and why it leaves it empty?
