Operator Internet Archive


Snapshots websites for historical databases

Expected Behavior

Archivers visit websites on a roughly regular cadence, since snapshots are more useful when they're regularly spaced out. Popular websites will have more frequent visits since they are more likely to be queried in the historical database in the future.


Activity on Your Website

Half of your website's traffic probably comes from artificial agents, and they're becoming more intelligent every day.

Should I Block heritrix?

It's up to you. Digital archiving is generally done to preserve a historical record. If you don't want to be part of that record for some reason, you can block archivers.

Using Robots.txt

User Agent Token Description
heritrix Should match instances of heritrix

You can block heritrix or limit its access by setting user agent token rules in your website's robots.txt.

# robots.txt
# This should block heritrix

User-agent: heritrix
Disallow: /

Instead of doing this manually, you can generate a robots.txt that stays up to date with the agent list automatically.
