About GhostExplore

An aggregator service for websites powered by ghost.org

Aggregators collect articles and links from many sites to build news feeds, read later apps and discovery services. Some send referral traffic, others republish your content. Check what each one does with your pages before allowing it.

GhostExplore user agent

GhostExplore identifies itself with this user agent string:

  • GhostExplore/1.0 (+https://explore.ghost.org/bot)

Anyone can copy a user agent string. Transfon Security also checks where each request comes from, so a request that claims to be a known crawler but comes from the wrong network is treated as a fake, not as the real crawler.

How to block GhostExplore in robots.txt

We have not confirmed whether GhostExplore follows robots.txt. Add a rule, then check your logs to see that it stopped. robots.txt is a plain text file at the root of your domain, such as https://example.com/robots.txt.

Things to know

  • Each host needs its own file. Rules on www.example.com do not apply to shop.example.com.
  • A crawler obeys only the most specific group that names it. Once you add a User-agent: GhostExplore group, GhostExplore ignores your User-agent: * rules, so repeat any that should still apply.
  • The user agent name is not case sensitive. We take GhostExplore from GhostExplore's user agent; check Ghost's own documentation if it publishes a different robots.txt name.
  • Crawlers cache robots.txt, so changes can take up to a day to apply. Disallow stops crawling but does not remove pages already collected or indexed.

Limits of robots.txt

  1. GhostExplore may not follow the rule. robots.txt is a request that nothing enforces, and we have not confirmed that GhostExplore follows it. Check your logs after adding a rule.
  2. The user agent could be fake. robots.txt matches the name a request claims. Anyone can send GhostExplore's user agent, and a scraper using it is not bound by Ghost's robots.txt policy. Only checking the source network tells a real GhostExplore from a fake one.

Treat robots.txt as a statement of your policy, and enforce it where requests arrive.

Who should care about GhostExplore

Publishers

GhostExplore fetches pages when your links are shared or syndicated. Keep it allowed so previews and feeds work, but leave it out of page views and ad requests.

Transfon Security for publishers

Media buyers and advertisers

When ads or posts are shared, GhostExplore fetches the landing page. Those hits are not clicks, so keep them out of campaign reports.

E-commerce

Product links shared in chats and feeds are fetched by GhostExplore. Keep it allowed so previews show the right image and price.

Does GhostExplore respect robots.txt?

We have not confirmed whether GhostExplore follows robots.txt. Add a robots.txt rule, then check your logs to see that it stopped, and block it by user agent if it did not.

How do I block GhostExplore?

Add "User-agent: GhostExplore" followed by "Disallow: /" to the robots.txt file at the root of your site. To enforce it, block requests whose user agent contains "GhostExplore" at your WAF. In Transfon Security that is one User Agent block rule.

Is robots.txt enough to block GhostExplore?

No. robots.txt is voluntary, so GhostExplore may not follow it, and anyone can send GhostExplore's user agent, so a fake GhostExplore ignores your rule. Enforce the rule where requests arrive, at your WAF, and check the source network.
