There are three types of cookies that contain information of value: __utma, __utmb and __utmz. The four main (debatable, I know) browsers store them differently. Internet Explorer stores them in a text file, Firefox and Chrome in an SQLite database, and Safari in a plist file.
The values in the data base look something like this:
- __utma: 191645736.1125870631.1349411172.1349411172.1349411172.1
- __utmb: 140029522.214.171.1249409002
- __utmz: 140029553.1349409002.1.1.utmcsr=google|utmccn=(organic)|utmcmd=organic|utmctr=php%20email%20throttling
I have written one tool that will parse the Google Analytics cookies for these four browsers, GA Cookie Cruncher:
Internet Explorer - point the tool to the folder containing the cookies (either export out the cookies folder, or mount the image). The tool will read each cookie within the folder, determine if it has these values and parse them accordingly.
Chrome – point the tool to the cookies sqlite database (either exported from your image, or mounted). The tool will query the database for all the Google Analytics values and parse accordingly.
Safari (Mac) – point the tool the the cookies.plist file. It will parse the plist file and the the Google Analytics cookies within.
Firefox- The Firefox cookies are stored in an SQLite database. Unfortunately, the wrapper library I used can not access this SQLite Database. I also tried to test the Firefox cookies database with the free SQLite Browser which could not read it either. So far, the only tool I have been able to access this database with is the SQLite Manager plugin for Firefox.
I have included a little hint in the "Browser Information" box to remind you where the default location of these cookies are for whatever browser you select. I cant event remember where I put my keys, so I thought this might be helpful.
The program creates 3 files in CSV format: %Browesername%_UTMA, %Browesername%_UTMB and %Browesername%_UTMZ
Here is some sample output from Internet Explorer from a __utmz cookie:
Now, I haven’t tested this on every browser version out there, and I have seen some variations on the way the cookies are stored. Some initial tests indicate that IE 9 does not seem to track these values, but more research will need to be done to confirm (thanks to cheeky4n6monkey for the testing). If the tool does not read your cookie file, I'm happy to help, just shoot me an email.
