How to block ImagesiftBot in robots.txt

What ImagesiftBot is

ImagesiftBot is the crawler behind ImageSift, which collects and indexes images from the public web for an image-search service and associated datasets. Because image datasets are frequently reused for AI training, operators who care about image rights often choose to block it.

ImageSift publishes documentation describing the crawler, its robots.txt token, and how to opt out. Use that documentation rather than guessing the user-agent string.

The rule

To disallow ImagesiftBot site-wide, target its token:

User-agent: ImagesiftBot Disallow: /

The user-agent string contains the ImagesiftBot token plus a self-identifying URL. Match the stable token. If your concern is images specifically, remember that some other crawlers fetch images under their main token, so a complete image policy may require several rules. robots.txt is a request, not enforcement.

How it appears in analytics and logs

A request carrying the ImagesiftBot token is ImageSift's crawler fetching a page or image. It is a bot event focused on image discovery, not a human visit.

Diagnostic use case

Disallow ImagesiftBot when you do not want your images crawled into the ImageSift index or its associated datasets, which can be used for image search and AI training.

What WebmasterID can help detect

WebmasterID classifies ImagesiftBot by its token, separate from human analytics, so you can confirm whether a disallow rule reduced its image-focused crawling.

Common mistakes

Privacy and accuracy notes

Blocking ImagesiftBot is a publishing-policy choice in a public file. It involves no visitor data and is not an access-control boundary.
