Technical FAQ: Bio Link Cloaking & WebView Breakout
How social link scanners inspect bio URLs and how SneakyLink neutralizes them.
What does the Social Bio Link Ban & In-App Browser Checker test?
Our diagnostic engine simulates a live inspection from Meta's link crawler (facebookexternalhit/1.1) and evaluates 10 security vectors: raw HTML outbound URL exposure, shared aggregator domain burn, plaintext keyword leaks, static link exposure, In-App Browser Safari/Chrome breakout headers, Canary honey-token traps, Referrer-Policy stripping, noindex directives, Content-Security-Policy hardening, and supplier fingerprint concealment.
Why does Instagram's In-App Browser hurt creator conversion rates?
Instagram and TikTok open standard bio links inside an isolated embedded WebView that does not share cookies, saved passwords, or Apple Pay sessions with the user's main Safari or Chrome browser—causing up to 65% of fans to abandon checkout.
How do I get a 100/100 Stealth Score for my bio link?
Every SneakyLink page (and connected personal custom domain) automatically passes all 10 crawler and WebView breakout checks with a 100/100 score out of the box.
