BufferLinkPreviewBot

Praevisor socialis

What is BufferLinkPreviewBot?

Buffer’s link preview fetcher. When a Buffer user adds a link to a social media post, it reads the page’s title, description, images and Open Graph and Twitter Card tags to show how the post will look. It is operated by Buffer and identifies itself as BufferLinkPreviewBot.

Temperament: punctual. Gets the picture ready before the post goes out.

Identification

Its full user-agent string, exactly as it arrives at the gate:

User-Agent
$ BufferLinkPreviewBot/1.0 (+https://scraper.buffer.com/about/bots/link-preview-bot)

Buffer lists the bot’s IP addresses on its bot page, and the bot sends an X-BufferLinkPreviewBot header. The zoo doesn't check these yet, so visits are filed by their user agent. Read Buffer's documentation.

IdentitySigned by its operator, not yet checked here

Buffer signs its requests, but the zoo doesn't check signatures yet, so every visit filed here is taken at its word for now.

How to block BufferLinkPreviewBot

Add these two lines to the robots.txt file at the root of your site. Well-behaved crawlers read it before they crawl, so the change applies from BufferLinkPreviewBot's next visit. Nothing else on your site needs to change.

robots.txt
# Block BufferLinkPreviewBot from the whole site
User-agent: BufferLinkPreviewBot
Disallow: /

It honours robots.txt. Blocking it means Buffer posts that link to your site will have no preview.

Or let it visit but keep it away from part of the site:

# Let it in, but keep it out of one room
User-agent: BufferLinkPreviewBot
Allow: /
Disallow: /members/

Questions site owners ask

Does BufferLinkPreviewBot respect robots.txt?

Yes. In 8 requests observed here it has read robots.txt and never fetched a disallowed page.

Will blocking BufferLinkPreviewBot hurt my search rankings?

No. But links to your site will be shared without a title or preview image, which tends to get fewer clicks.

How often does BufferLinkPreviewBot visit?

Here, about 0 requests a day over the last week. Visits to your site depend on its size, how often it changes, and how many links point to it.
