Embedly is a bot in the link preview bots category, operated by Embedly.
Embedly link preview service (operated by Medium) that fetches metadata and embeds for URLs.
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.
Embedly identifies itself with this user agent string:
Mozilla/5.0 (compatible; Embedly/0.2; +http://support.embed.ly/)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.
We have not confirmed whether Embedly 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.
User-agent: Embedly Disallow: /
User-agent: Embedly Disallow: /private/ Disallow: /search
User-agent: Embedly Allow: /blog/ Disallow: /
User-agent: Embedly Allow: / User-agent: * Disallow: /
User-agent: Embedly group, Embedly ignores your User-agent: * rules, so repeat any that should still apply.Embedly from Embedly's user agent; check Embedly's own documentation if it publishes a different robots.txt name.Treat robots.txt as a statement of your policy, and enforce it where requests arrive.
Embedly 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 publishersWhen ads or posts are shared, Embedly fetches the landing page. Those hits are not clicks, so keep them out of campaign reports.
Transfon Security for advertisersProduct links shared in chats and feeds are fetched by Embedly. Keep it allowed so previews show the right image and price.
Transfon Security for e-commerceAllow Embedly on public pages so shared links preview well, and keep it off the app.
Transfon Security for SaaS and APIsrobots.txt is a request, not an enforcement. Transfon Security shows Embedly by name in the Top Bots report, so you can see how often it visits and which pages it reads. Block or allow it with a User Agent rule, or slow it down with a rate limit decision rule.

We have not confirmed whether Embedly 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.
Add "User-agent: Embedly" followed by "Disallow: /" to the robots.txt file at the root of your site. To enforce it, block requests whose user agent contains "Embedly" at your WAF. In Transfon Security that is one User Agent block rule.
No. robots.txt is voluntary, so Embedly may not follow it, and anyone can send Embedly's user agent, so a fake Embedly ignores your rule. Enforce the rule where requests arrive, at your WAF, and check the source network.
