What Proximic does
The Proximic crawler is Comscore's web crawler for contextual content analysis, which lets Comscore's advertising partners match campaigns with page content. It downloads only static, textual content, does not execute JavaScript, and does not generate ad impressions; rather than extracting source code, it derives metadata such as language, content ratings, and IAB categories. Pages are visited either when ads are about to be served on them or in a linear fashion for site-level analysis, with timing that depends on factors like content type, content changes, and the number of ad elements. It identifies itself as Mozilla/5.0 (compatible; proximic; +https://www.comscore.com/Web-Crawler).
How to control Proximic
Target Proximic in your robots.txt with the proximic token. Rules apply per bot, so you can allow this one while blocking others, or the reverse.
Allow Proximic
User-agent: proximic
Allow: /Block Proximic
User-agent: proximic
Disallow: /The crawler's default rate is one request per second, adjustable with a Crawl-Delay directive, and Comscore notes that robots.txt changes can take up to a day to take effect.
How to identify Proximic
Temso identifies Proximictraffic by matching the request's User-Agent header against this pattern. User-agent strings can be spoofed, so treat a match as an indication, not proof.

What is Proximic?
Proximic is Comscore's web crawler. It downloads the static text of web pages to run contextual content analysis, producing metadata such as language, content ratings, and IAB categories that advertising partners use to match campaigns with page content.
How do I block Proximic?
Add a robots.txt group with User-agent: proximic and Disallow: / in the robots.txt file at your site's root, or use Disallow: /path/ to exclude specific paths. Comscore notes that robots.txt changes can take up to a day to propagate, and a Crawl-Delay directive can be used to slow the default rate of one request per second instead of blocking.
About Advertising Bots
Bots run by ad platforms to check landing pages, verify ad placements, and analyze content for brand safety and targeting.
If you run ads on a platform, its ad bots usually need access; blocking them can break ad approval and quality checks for your own campaigns.
