Last month, I noticed a 300% increase in average Time Spent on Site as reported by Google Analytics. Apparently, Google changed how they reported Time Spent on Site. After some digging and helpful comments from users on this blog, it looks like Google no longer included visitors who bounced in their length-of-stay measurement. Google even retroactively updated reports from previous months as well and many users reported a significant increase in the length-of-time visitors stayed on their website. Looks like Google might have dropped this new method of measuring and reverted back to their original formula.
When Google made the original change in reporting they should have made a formal announcement. Now that they have reverted back to the former method of reporting, an announcement to their users would have been helpful in explaining the sudden increase and decrease in times spent on site over the past few months.
As of today, Google Analytics is reporting times more indicative from before they dropped bounced users. Anyone else seeing this as well?
