Welcome to WebmasterWorld Guest from 22.214.171.124
The hit referrer was from google.com/search like all the rest and the destination URL had our id tag in it but the "q=" portion that always contains what was searched for looked like:
No quotes of course. Now I realize that "%20" is the hex representation of a space but what confuses me is that for all the other thousands of entries, spaces are represented by the "+" plus sign.
I also realize there is a slim chance that some extreme nerd type actually typed the search parameters in like that but I seriously doubt it. Keep in mind that I'm talking about the Referrer field for a Google AdWords hit.
I'm not going to lose a lot of sleep over it, I'm going to just convert them to spaces for reporting purposes but it just struck me as very odd.
Granted this is my first day of writing code to parse our logs for what it's worth.
