PrintFriendly
PrintFriendly is a single-page fetcher operated by Printfriendlycom. It fetches one page (or a small set) when triggered by a user action, typically a link being shared on social media, a messaging app, or an RSS reader.
Volume tracks shares and clicks rather than crawl schedules. A trending link can produce a sudden spike, but PrintFriendly will not crawl the rest of your site.
Blocking it usually means the link previews on the corresponding platform stop showing your title, image, and description.

For higher confidence, also verify the source IP against the operator's published ranges. UA strings can be spoofed; IP ownership is harder to fake.

Should I let PrintFriendly through?
In most cases, yes. Fetchers power link previews and feed readers. Blocking breaks the user experience on social and messaging platforms. If volume gets noisy, rate-limit it before you block it outright.
Does blocking PrintFriendly affect my Google rankings?
No. PrintFriendly is not a search-engine crawler. Your ranking on Google or Bing is unaffected by what you do here.
How do I confirm a request is really from PrintFriendly?
Look at the User-Agent header in your access logs and match it against the strings listed above. Worth knowing that the User-Agent is easy to fake, so this check tells you "the traffic claims to be PrintFriendly", not "the traffic is genuinely PrintFriendly". If you need stronger guarantees, look for a reverse-DNS check or wait for Printfriendlycom to publish IP ranges.
What breaks if I block PrintFriendly?
Link previews, embeds, and unfurls on whatever surface PrintFriendly feeds will stop rendering. Users sharing your URLs into Printfriendlycom will see a bare link instead of a rich card. Usually that's the first thing people regret blocking.
What's the cleanest way to control PrintFriendly?
Two layers. Robots.txt for the polite crawlers that read it, and rules at your CDN or edge for the ones that don't. Rankly's Agent Experience handles both from a single config, so you can allow, block, rate-limit, or serve a stripped-down version per bot. Agent Analytics handles the observation half so you know which bots are actually worth a rule.
