CobaltmetricsBot is the bot that we send out to discover and index citation data.

How Cobaltmetrics crawls the web

There is currently a short list of websites that Cobaltmetrics crawls: see our page on data sources for a complete list. More information about how and how often we crawl these primary data sources is coming soon.

While CobaltmetricsBot is both harmless and beneficial, you might want to prevent it from accessing some resources on your website. The best way to do so is to add or update the robots.txt configuration of your website (see http://www.robotstxt.org/ for more information). The full user-agent string is CobaltmetricsBot/1.0 (+https://cobaltmetrics.com). Where several user-agents are recognized in the robots.txt file, CobaltmetricsBot will follow the most specific.


If you have any questions about CobaltmetricsBot, please contact us and we will respond as soon as possible.

If you think that CobaltmetricsBot does not obey your robots.txt configuration, please contact us with your URLs, the logs showing CobaltmetricsBot accessing pages that it was not supposed to, and we will work quickly to fix the issue.
