Web monitoring tool
Monitor the web for what matters to you
Track brand mentions, competitor moves, and breaking news the moment they’re published.
The brand monitoring and competitor monitoring tool built on Ahrefs’ web index since 2010
Built on AhrefsBot
One of the web’s most active crawlers, now watching in real time instead of on Ahrefs’ regular crawl schedule.
The intel Ahrefs surfaces, now live
Site Explorer and Content Explorer show what already ranks. Firehose tells you the moment a competitor publishes, before it shows up in any crawl report.
One data foundation you already trust
No separate crawl infrastructure to vet. It’s the same web index Ahrefs analyzes for SEO, streamed to you as it changes.
Historical data
Site Explorer, Rank Tracker, and Content Explorer show you the state of the web as of the last crawl: rankings, backlinks, and content that already exists.
What’s happening right now
Firehose watches the same web for the moment something new is published (a mention, a competitor page, a story) and notifies you instantly.
Two ways to stay ahead of the web
Describe what you want to track. Firehose notifies you the instant something matches: no polling, no digests.
Watch the whole web
“Tell me about any page that matches this pattern.”
Best for brand mentions, competitor moves, breaking news
Filter by keyword, site, language, or page type
Matches land in your dashboard or your own tools via API
Watch pages you know
“Tell me when these specific pages change.”
Best for pricing pages, docs, terms, competitor landing pages
Checks on the schedule you set
Shows exactly what changed since last time
Use it as a brand monitoring tool, a competitor monitoring tool, or both at once
Brand & competitor mentions
Every page that mentions your brand or a rival, the moment it’s published anywhere.
News on your topic
Coverage of your topic the hour it’s published, not in tomorrow’s digest.
Brand-new pages
New product pages, job posts, or press releases as they go up, across thousands of sites.
Only trusted sources
Mentions from trusted, high-authority sites; quiet from everywhere else.
