Since April, I've been beta testing Google AgencyLand. Now, I can talk about it
One of the most useful features is the weekly update. Here's an example from the week of June 17, 2009:
Must Know Product Updates
Search Query Performance Report Update
If you’ve recently run a Search Query Performance Report (SQR) you may have noticed 'Broad (Session-Based)' in the 'Search Query Match Type' column. As you may be aware, when determining which ads to show on Google.com, the system evaluates some of the user's previous queries during his search session as well as the current search query. If the system detects a relationship, it will show ads related to these other queries. Such matches were previously reported as 'Broad match' and are now marked as 'Broad (Session-Based)' in SQRs.
We hope this update offers more granular insight into how your keywords are performing. If you find that a particular query is performing well, consider adding the keyword to your ad group. Conversely, such data can help identify potential terms to add as negative keywords. Visit the Help Center for a more detailed description of Search Query Match Type as well as an explanation of session-based broad matches.
Wouldn't it be useful to know about these kinds of changes, before or as they're rolled out? I'm not even sure if this change has been announced on any of the official Google blogs.
If you work for an agency, make sure you're signed up for the Google AgencyLand trial
