Google Analytics Changes
On the 11th August, Google implemented a major update to the way sessions are reported in Google Analytics. The change helps determine which traffic sources result in the most conversions. To get an accurate idea of how a site visitor behaves each time they reach your site, Google and other analytics tools determine when a user has reached a new “session.” Each session counts as its own visit, impacting key metrics such as page views, time on site, and total visitor count
Google Analytics sessions used to be worked out using the below criteria:
• When the user has been inactive on the website for 30 minutes
• At the end of the day all sessions are considered closed
• When the user closes their web browser
Earlier this month Google Analytics have changed to the below criteria
• When a user has been inactive for 30 minutes & also at the end of the day all sessions are considered closed
• When the source campaign for the user changes – this information relates to campaign tracking information – which can be set up manually in links – for example on your email newsletter, or is sent via AdWords auto-tagging.
What does this mean?
If the user leaves the site and then re-enters from a new source, it counts as a new session. For example, if a user landed on a page through your PPC campaign, left to do some research, then arrived at the same page within 30 minutes through another source (let’s say Twitter) and converted, Google Analytics would count it as one PPC session.
Now, this activity will merit two separate sessions, and marketers can see that the hypothetical visitor converted when he or she came from the social source. Also if a user checks out an article on your site because they found it by searching for one term, then leaves your site and finds another article based on another term, each visit counts as a new session.
Note that sessions will no longer end just because a user closes their browser. Google now assumes that users who close the browser and then return to your site may be experiencing any number of internet phenomena, including a browser crash or casually browsing around a site while engaging in other activities. By continuing a session when the user closes their browser for only a very short time, sessions will more accurately model a user’s engagement with the website.
How does this affect my stats? What changes will I see?
All historic data in Analytics will be measured by the old session definition. As for new data, MAD are seeing, in some cases, a sizeable increase in the total number of visits (i.e., sessions) and a correlating decrease in other metrics (e.g., time on site, page views, etc.). There’s no impact on unique visitors, page views, conversions and time on site.
This update also helps M.A.D in using the new Multi Channel Funnels in Analytics, that Google has released this week. For a great overview video from Google, visit http://www.google.com/analytics/analytics-funnels.html
While we’re on the topic of Google Analytics updates, you may have noticed an increase in your organic traffic. Traffic from images.google.com is now being registered as organic traffic not referral traffic. This update allows you to report on what search terms visitors came to your site on when referred to by Google Image Search.
