What a bot for ads, link previews or SEO tools does
These bots work for a specific product: checking an ad's landing page, drawing the preview when a link is shared, or collecting data for an SEO tool. Some only visit because the site owner asked them to.
Majestic supports Crawl-delay up to 20 seconds. It publishes no IP list; site owners can ask it to send a private identifier instead.
Block or allow MJ12bot in robots.txt
Add one of these to the robots.txt file at the root of your domain. Crawlers read it before they fetch anything else.
