Common URL Encodings
What Is URL Encoding?
URL encoding (also called percent-encoding) converts characters that aren't allowed in URLs into a format that can be transmitted over the internet. Special characters are replaced with a "%" followed by their hexadecimal value. For example, a space becomes %20 and an ampersand becomes %26.
Why URL Encoding Matters for SEO
Clean URLs are a minor SEO ranking factor. Search engines prefer readable URLs without excessive percent-encoding. When building dynamic URLs with query parameters, ensure special characters are properly encoded to prevent broken links and crawl errors. AI search engines also parse URLs to understand page content — a clean URL structure helps.
