Frequently Asked Questions
What are HTML entities?
HTML entities are special codes that represent characters that have meaning in HTML (like < > &) or characters not on a standard keyboard. For example, < is < and & is &.
When should I encode HTML entities?
Encode when displaying user input on web pages (XSS prevention), including special characters in HTML attributes, or when a character cannot be typed directly.
What is the difference between named and numeric entities?
Named entities use descriptive names (© for ©) while numeric use Unicode code points (©). Named are more readable but numeric support more characters.
Does encoding affect SEO?
No, search engines decode entities before indexing. Using & instead of & in URLs and content is standard practice and does not impact SEO.
