Alerts are an important feature in Techtracker. Alerts are pushed every 24 hours, so you will not see data instantly when you save an alert. Alerts are running in the cycle with our technology crawlers. So, when we scan a change in 200 million domain names and the change is related to any one of your alets, Techtracker will send you an alert. This simply means that you should not expect a daily alert if you track a niche technology.So be patient and alerts will show when a change is tracked, that is the magic :)
