What is Pinterestbot?

Pinterestbot crawls images and pages to validate and display content pinned by users on Pinterest.

Pinterestbot crawls images and pages to validate and display content pinned by users on Pinterest. Pinterestbot is operated by Pinterest to generate rich link previews when URLs are shared on their platform. It sends GET requests to your URL, reads <meta property="og:..."> and <meta name="twitter:..."> tags, and caches the result. Blocking Pinterestbot means all links to your domain shared on Pinterest appear as raw text without thumbnail, title, or description. This can reduce CTR from social referrals but has zero SEO impact.

Will blocking Pinterestbot hurt my SEO?
❓ **Impact Unknown** — The SEO consequences of blocking Pinterestbot are not fully documented. Before blocking, check your analytics to confirm whether this bot generates referral traffic, review your server logs for crawl frequency, and test in a staging environment if possible.
How do I block Pinterestbot in robots.txt?
Add the following lines to your /robots.txt file:
User-agent: Pinterestbot
Disallow: /
This instructs Pinterestbot not to crawl any path on your site. The Disallow: / directive covers the entire domain including subfolders. To only block specific sections, replace / with the path (e.g., Disallow: /blog/). Note: robots.txt is publicly readable — any bot or human can inspect it at yourdomain.com/robots.txt.
Does Pinterestbot respect robots.txt?
Yes — Pinterestbot is a well-behaved bot operated by Pinterest. It fetches and parses /robots.txt before crawling any page, following RFC 9309.
How do I verify if Pinterestbot is crawling my site?
Search your web server access logs for the string Pinterestbot (case-insensitive grep: grep -i "Pinterestbot" /var/log/nginx/access.log). You can also check Google Search Console → Coverage → Crawl Stats for Googlebot variants. For Pinterestbot specifically, filter by user-agent in your log analysis tool (GoAccess, AWStats, etc.).
What is the crawl frequency of Pinterestbot?
Pinterestbot crawls at a moderate rate. If you notice excessive traffic in your logs, you can add a Crawl-delay directive:
User-agent: Pinterestbot
Crawl-delay: 10
(10 second delay between requests).
Can I block Pinterestbot from specific pages only?
Yes. Instead of a global Disallow: / you can restrict Pinterestbot to specific paths:
User-agent: Pinterestbot
Disallow: /private/
Disallow: /staging/
Allow: /
This allows Pinterestbot everywhere except the listed paths. Path matching in robots.txt uses prefix matching — Disallow: /private/ blocks /private/page.html but NOT /public/private/.
Why is my link preview broken when shared on Pinterest's platform?
If links to your site appear without a preview image or title on Pinterest, it's likely because: 1. Pinterestbot (Pinterestbot) is blocked in your robots.txt. 2. Your Open Graph meta tags are missing or malformed. 3. Pinterest's cache is stale — request a refresh using Pinterest's debugger tool. Fix: Remove any block rule for Pinterestbot and ensure your pages include <meta property="og:title">, og:description, and og:image.
