About PressEngineBot

The PressEngine Bot verifies coverage created by video games press as genuine and their own creation. When a member of the video games press is granted a review key for a video game they will create an article, known in the industry as "coverage". When they submit a URL to us as "coverage" we automatically verify this URL exists and is viewable. This automated code announces itself as the PressEngine Bot.

Link preview bots fetch a page when someone shares its URL in a chat app or social network, to build the preview card. Blocking them breaks your link previews, so keep them allowed but leave them out of analytics and ad requests.

PressEngineBot user agent

PressEngineBot identifies itself with this user agent string:

  • PressEngineBot (+http://pressengine.net/crawl-policy)

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 PressEngineBot in robots.txt

PressEngineBot follows robots.txt, so these rules stop it crawling the paths you choose. robots.txt is a plain text file at the root of your domain, such as https://example.com/robots.txt.

Block PressEngineBot from the whole site

User-agent: PressEngineBot
Disallow: /

Block PressEngineBot from some folders

User-agent: PressEngineBot
Disallow: /private/
Disallow: /search

Allow PressEngineBot only on some folders

User-agent: PressEngineBot
Allow: /blog/
Disallow: /

Allow PressEngineBot and block other crawlers

User-agent: PressEngineBot
Allow: /

User-agent: *
Disallow: /

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: PressEngineBot group, PressEngineBot ignores your User-agent: * rules, so repeat any that should still apply.
  • The user agent name is not case sensitive. We take PressEngineBot from PressEngineBot's user agent; check PressEngine'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. PressEngineBot may not follow the rule. PressEngineBot says it follows robots.txt, but nothing enforces that. Changes can take a day to apply, the operator can change its policy, and other crawlers from PressEngine use different names and rules.
  2. The user agent could be fake. robots.txt matches the name a request claims. Anyone can send PressEngineBot's user agent, and a scraper using it is not bound by PressEngine's robots.txt policy. Only checking the source network tells a real PressEngineBot from a fake one.

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

Who should care about PressEngineBot

Publishers

PressEngineBot 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, PressEngineBot 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 PressEngineBot. Keep it allowed so previews show the right image and price.

Does PressEngineBot respect robots.txt?

Yes. PressEngineBot follows robots.txt, so a Disallow rule for the PressEngineBot user agent stops it from crawling the paths you list.

How do I block PressEngineBot?

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

Is robots.txt enough to block PressEngineBot?

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