What user-agent string identifies AddThis?

The recorded string is `AddThis.com (http://support.addthis.com/)`. Match the stable `AddThis` token when classifying traffic or writing a robots.txt group.

Will AddThis obey robots.txt?

Compliance is unconfirmed in this catalog, and the Cloudflare record marks it as not following robots.txt. Treat a rule as a stated preference and verify the result in access logs.

What could break if I block AddThis?

Blocking may prevent AddThis from refreshing page information used by sharing or recommendation features. The record does not document any effect on sites that do not use those tools.

Does AddThis affect AI search or training?

No such role is documented. An AddThis request is tied to its website marketing tools, not to an AI answer index or a model-training collection process.

AddThis & AI Search: What to Know

What is AddThis?

AddThis crawls pages to gather and refresh content used by its website marketing tools. The record names social sharing buttons and content recommendation widgets as the services behind this activity. Its requests are part of maintaining those features, rather than a general search engine crawl.

The recorded user agent is AddThis.com (http://support.addthis.com/), with AddThis as the stable matching token. A visit means a client claiming that identity requested the page. It does not reveal which AddThis feature caused the request or whether the page was later shown in a recommendation widget.

Robots.txt support is not settled. This catalog leaves compliance unconfirmed, while the accompanying Cloudflare record says the crawler does not follow robots.txt. There is also no listed request signature or verified IP method, so the user-agent text alone cannot authenticate AddThis traffic.

Nothing in the bot record connects AddThis to AI answer retrieval or model training. Allowing it may matter to a site that still uses AddThis sharing or recommendation tools, but it should not be presented as a route into AI search. Blocking it is likewise not an AI training opt-out.

Indirectly relevant

Is AddThis relevant for AI search?

Indirectly. AddThis has no AI product of its own, but its output can end up in the systems that AI answers draw on.

AddThis is an SEO auditing crawler. It has no direct effect on search rankings or AI answers, but the reports it feeds are used to fix crawlability and content issues that do affect how search and AI systems see your site.

How to handle AddThis

First check whether the site still runs an AddThis sharing button or recommendation widget. If it does, compare the requested paths with the public content those tools need before applying a site-wide restriction. Sites that no longer use AddThis have less reason to accept the crawl.

Use the stable token to state a site-wide preference:

User-agent: AddThis
Disallow: /

The source records do not establish dependable robots.txt compliance. Check subsequent access logs after publishing the rule. If the requests must stop, enforce the decision at the edge or application instead of relying on the claimed user agent as proof of identity.

Examples

A publisher that uses an AddThis recommendation widget sees `AddThis.com` fetch newly edited article URLs and keeps those public routes available.
A company removed its sharing tools months ago but still sees the `AddThis` token. It adds a specific robots rule, checks later requests, and uses an edge rule if the traffic continues.
