Google has added two more filter and delivery options to Google Alerts. Google Alerts informs you of updates within Google results via email or RSS feed.
The two new filters let you refine those alerts by language or region. You can tell Google you only want alerts for specific keyword phrases within a specific region or country or a specific language. You can select all regions or languages or you can be specific and specify one language or region. You cannot currently select a select number of regions or languages, it is either all or one.
Here is a picture of the new Google Alerts screen:
Hat tip to Alex Chitu for noticing this change.
