I've used Google Alerts without any trouble for over 3 years. Most of my keywords are longtail. Despite that, I used to receive alerts at least weekly. Since the beginning of May, I have not received ANY alerts. I went to the troubleshooting section and checked that they weren't being caught in my spam folder.
Anybody else had a total drop off in Google Alerts? I saw it proposed that with caffeine, the index is smaller and therefore excludes much longtail content. Is this perhaps related?
