WPCentrifyBot
WPCentrifyBot is the crawler and link checker of WPCentrify, a service web agencies use to look after their clients' WordPress websites.
What it does
- Reads websites our customers have connected. When a website's owner connects it to WPCentrify, WPCentrifyBot reads its pages to report SEO problems, broken links and speed back to that owner.
- Checks the links on those websites. When one of those pages links to your website, WPCentrifyBot asks your server whether that one page is still there, so our customer can fix a link that no longer works. It reads only the status and the page title, never stores your content, and asks about each address about once every 7 days.
It does not train AI models, collect prices or build a search index, and it never fills in forms or signs in.
How it identifies itself
Every request carries this user agent:
Mozilla/5.0 (compatible; WPCentrifyBot/1.0; +https://api.wpcentrify.com/bot)
Every request is also signed with Web Bot Auth (HTTP Message Signatures, RFC 9421), so a request that only borrows the name can be told apart from ours. Our public keys are published at:
https://api.wpcentrify.com/.well-known/http-message-signatures-directory
Robots.txt
Before checking a link to your website, WPCentrifyBot reads your robots.txt and keeps to it, including Crawl-delay. To stop it visiting your website, add:
User-agent: WPCentrifyBot Disallow: /
Pages on a website whose owner connected it to WPCentrify are read because that owner asked us to check them.
How often it visits
A few requests to any one website at a time, spread over minutes, and each linked address about once every 7 days. If you see more than that, or anything you did not expect, please tell us.
