Email Obfuscator & Bot Shield Generator
Convert your email address into 4 bot-proof formats to prevent scraper harvesting.
Comparing Anti-Harvesting Protection Methods
Reverses the text in the raw DOM while CSS displays it normally. Extremely lightweight, requires zero JavaScript, and blocks 99% of basic regex scrapers.
Encodes characters into decimal and hex references. Perfectly parsed by all browsers and screen readers, but hides raw plaintext from naive HTML scrapers.
Encrypts the address with Caesar cipher and decrypts in the client DOM at runtime. Completely defeats headless bots that don't execute client JavaScript.
Frequently Asked Questions
How do email harvesting bots find email addresses on websites?
Automated scrapers crawl web pages and search HTML source code for email regex patterns (e.g. [a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}) and 'mailto:' anchor tags to compile spam mailing lists.
How does CSS Bi-directional text reversal work?
The email is written backwards in HTML source (e.g., 'moc.elpmaxe@tcatnoc'). The CSS property 'direction: rtl; unicode-bidi: bidi-override;' tells the web browser to render the letters from right to left visually. Human visitors see normal forward text, while scrapers reading raw HTML only see reversed, unusable strings.
Will obfuscated email addresses hurt my website SEO?
No. Search engines like Google prioritize user experience and recognize standard HTML entity and CSS techniques. Obfuscation does not violate Google Webmaster guidelines.
