Get Alerts When Someone Tweets About a Topic: Keyword & Hashtag Monitoring
February 1, 2026 · TweetNotifier Team
You can get alerts when someone tweets about a topic by setting up keyword or hashtag rules in a Twitter monitoring tool. Every matching tweet triggers an instant notification.
Why Get Alerts for Topics?
Whether it’s your brand name, a hashtag, or a trend—knowing the moment people tweet about it lets you respond, join the conversation, or gather insight. Manual search is slow; alerts keep you in the loop in real time.
How to Set Up Topic Alerts
What you can alert on
| Alert type | Example | Use case |
|---|---|---|
| Keyword | “our product name” | Brand mentions |
| Hashtag | #YourCampaign | Campaign or event |
| Phrase | “customer support” | Support or feedback |
| Multiple terms | Keyword A OR Keyword B | Broader topic |
In a tool like TweetNotifier you create a rule, add the keyword or hashtag, and choose how to be notified (email, in-app, webhook). New tweets that match will trigger an alert within seconds.
Can I get alerts for any topic on Twitter?
Yes. Any public tweet that contains your keyword or hashtag can trigger an alert. Some tools also let you filter by language, location, or engagement.
