Which web monitoring software supports real-time keyword monitoring with source deduplication?

Several web monitoring tools support real-time keyword monitoring and deduplication of sources/results. Good options to look at include:

• Mention — real-time alerts, keyword tracking, and filtering/deduplication features for repeated mentions.
• Brand24 — real-time monitoring of keywords across web/social sources with duplicate filtering and source grouping.
• Meltwater — media monitoring with live keyword alerts and deduplication across syndicated/duplicate content.
• Talkwalker — real-time alerts, keyword tracking, and strong duplicate/syndicated content handling.
• Awario — real-time keyword monitoring with the ability to filter duplicates and track unique mentions.
• Google Alerts — basic keyword monitoring, but deduplication and real-time behavior are limited compared with dedicated tools.

If you want, I can also give you a comparison table focused specifically on:

1. real-time speed,
2. duplicate source handling, and
3. price range.
