What AddThis.com means for your site
Every visit from AddThis.com means someone shared your URL on a social platform. The bot fetches your page to generate the link preview card (title, image, description) that appears in the conversation or feed. These are valuable visibility signals that traditional analytics miss entirely. High preview bot activity indicates your content is being shared and discussed.
What should you do?
- Allow AddThis.com, blocking breaks link previews
- Ensure Open Graph meta tags (og:title, og:description, og:image) are set on key pages
- Monitor share patterns to identify which content resonates
- Use BotSights to track social shares that Google Analytics misses

How to identify AddThis.com
AddThis.com uses the user-agent "AddThis.com". It robots.txt compliance unconfirmed.
AddThis.comaddthis.comHow to block AddThis.com
Three robots.txt options below. Pick the one that matches your goal. Each snippet lists every known AddThis.com user-agent pattern so the rules apply regardless of which one the bot announces. Compliance with robots.txt is unconfirmed for AddThis.com, so verify with crawl logs after deploying.
Edit robots.txt with care
A single misplaced line can de-index your entire site. Common mistake: pasting User-agent: * followed by Disallow: / blocks every bot, not just AddThis.com, including Googlebot. Always paste the snippet between existing rules (not over them), keep the User-agent line scoped to AddThis.com's patterns, and verify with Google's robots.txt tester before deploying. If you are not sure, ask a developer first.
Option 1: Block all access
Tells AddThis.com not to crawl any URL on your site. Use this when you want the bot completely off your content.
User-agent: AddThis.com
User-agent: addthis.com
Disallow: /Option 2: Block specific paths only
Keep public content crawlable but exclude sensitive or non-public sections. Add one Disallow: line per path. Replace the example paths with your own.
User-agent: AddThis.com
User-agent: addthis.com
Disallow: /admin/
Disallow: /private/
Disallow: /checkout/Option 3: Slow down with a crawl delay
Crawl-delay is a voluntary directive that asks the bot to wait the given number of seconds between requests. Useful when AddThis.com is hammering your origin and slowing the site down for real visitors, but you do not want to block it outright. The value is in seconds, so 10 means at most one request every ten seconds. Not all bots honour this directive (Googlebot ignores it; Bingbot, Yandex, and many AI crawlers do respect it).

Crawl-delay: 10Frequently Asked Questions
What is the User-Agent for AddThis.com?
AddThis.com identifies itself with the User-Agent string "AddThis.com" (alternate forms: addthis.com). This is the signature you will see in server logs when someone shares one of your URLs.
Does a visit from AddThis.com mean my link was shared?
Yes. Each visit represents a share event on this platform — someone either sent your URL in a private chat or posted it publicly. This is real share-volume data that traditional analytics like Google Analytics never see, because the visit happens server-to-server.
Should I block AddThis.com?
No. Blocking prevents link preview cards from rendering when your URLs are shared on this platform. Shared links without preview cards look broken and get fewer clicks. Always allow preview bots.
How do I improve how my link preview looks on this platform?
Add Open Graph meta tags to your pages: og:title (max ~60 chars), og:description (max ~155 chars), og:image (recommended 1200×630px PNG/JPEG). For X/Twitter add the twitter:* equivalents. Test with Facebook's Sharing Debugger or LinkedIn Post Inspector.
What image dimensions work best for AddThis.com?
1200×630 pixels (1.91:1 ratio) is the safest size that renders well on most platforms. Keep file size under 5MB and use PNG or JPEG. Avoid text near the edges since some platforms crop.
Why does my link preview show the wrong image?
Most preview platforms cache previews aggressively. After updating og:image, use the operator's debugger tool (e.g. Facebook Sharing Debugger, LinkedIn Post Inspector, X Cards Validator) to force a re-fetch, or add a query string to bust the cache.
Does AddThis.com respect robots.txt?
Compliance with robots.txt is unconfirmed. Most preview bots ignore it by design.
