MirrorWebCrawler - What It Is & How to Handle It

What is MirrorWebCrawler?

MirrorWebCrawler is MirrorWeb Ltd's content aggregator. We are a commercial web archiving supplier providing archival solutions for the financial and public sector.

MirrorWebCrawler collects and redistributes content from across the web, so pages it can reach may be surfaced to audiences well beyond your own site. Aggregated copies also become part of the corpus AI systems draw on, which makes it worth knowing what MirrorWebCrawler takes and how often.

Like any automated client, MirrorWebCrawler consumes crawl budget and appears in your server and CDN logs. Reviewing those logs alongside your robots.txt rules helps you keep automated traffic deliberate and easy to reason about.

Want to see every AI bot hitting your site? Promptwatch turns your server and CDN logs into a live view of AI crawler and agent traffic, so you can watch ChatGPT, Claude, Perplexity, Gemini, and others crawl your pages and connect those visits to real citations and revenue.

How to handle MirrorWebCrawler

To control MirrorWebCrawler, add a rule for its user agent to your robots.txt:

User-agent: mirrorweb
Disallow: /
