MicroAdBot is a bot in the advertising and marketing bots category, operated by MicroAd.
MicroAdBot reads pages for MicroAd, a Japanese advertising company, to classify them for ad targeting.
Advertising bots review landing pages, check ad placements and classify pages for brand safety and contextual targeting. Blocking ad verification bots can stop your ads or your inventory from serving, so allow the ones your ad partners use.
Anyone can copy a user agent string. Transfon Security also checks where each request comes from, so a request that claims to be a known crawler but comes from the wrong network is treated as a fake, not as the real crawler.
We have not confirmed whether MicroAdBot follows robots.txt. Add a rule, then check your logs to see that it stopped. robots.txt is a plain text file at the root of your domain, such as https://example.com/robots.txt.

MicroAdBot is a bot in the advertising and marketing bots category, operated by MicroAd. MicroAdBot reads pages for MicroAd, a Japanese advertising company, to classify them for ad targeting.
We have not confirmed whether MicroAdBot follows robots.txt. Add a robots.txt rule, then check your logs to see that it stopped, and block it by user agent if it did not.
Add "User-agent: MicroAdBot" followed by "Disallow: /" to the robots.txt file at the root of your site. To enforce it, block requests whose user agent contains "MicroAdBot" at your WAF. In Transfon Security that is one User Agent block rule.
No. robots.txt is voluntary, so MicroAdBot may not follow it, and anyone can send MicroAdBot's user agent, so a fake MicroAdBot ignores your rule. Enforce the rule where requests arrive, at your WAF, and check the source network.
