We use both Google Analytics and Site Catalyst V15. Recently we have seen a big discrepancy in visits. We are experiencing extra 12-15% visits in Site Catalyst compare to Google Analytics. Historically, we saw around 4-5% difference, which is acceptable . Is there any reason for this increase?
Are you seeing the discrepancy for this month? Were you using SC14?
From 1st Nov, SiteCatalyst report suites are migrated to v15 platform. The visits calculation in v15 is different from that of v14. You will see more visits in v15 because v15 include the visits from visitors that do not accept persistent cookies.
