Vercel 推出 BotID 技術，精準攔截偽裝爬蟲並防範隱蔽的 SEO 毒化攻擊

In modern web development, search engine optimization (SEO) is the lifeblood of website traffic. To ensure websites are properly indexed by Google or Bing, developers typically allow these search engine crawlers to pass through their Web Application Firewalls (WAFs). However, this has also created a security vulnerability: malicious actors have begun widely using "spoofed crawlers" — disguising their bots with Googlebot's User-Agent to bypass security protections. These malicious bots carry out "SEO poisoning attacks" on websites, such as injecting spam links, hijacking content, or mass-scraping sensitive data, severely damaging a site's search rankings and brand reputation.
