Has anyone else encountered some major problems with traffic tracking in google anayltics around September 17, and November 1st. Several of my sites abruptly dropped by almost the same percentage and are now tracking a much lower level. Is it possible Google implicated a sampling on my sites?
Could be, could not, but the bottom line is you should do something to index more often your by giving good content update & strong backlinks.
If I have one Google Analytic profile, and I am tracking like 20 or 30 different unique domains under the same account is this a bad practice. Should I create a profile with a unique GA code for every unique domain caus right now all the sites under that profille have an exactly identical UA-code?
