Frequently Asked Questions

What is a 404 error?+

404 Not Found means the server couldn't find the requested page. It doesn't mean the server is down — the server is working fine, but the specific URL doesn't exist. Common causes: deleted pages, changed URLs, or typos in links.

What is the difference between 301 and 302?+

301 is a permanent redirect — the page has moved permanently and search engines transfer link value (SEO juice) to the new URL. 302 is a temporary redirect — the page is temporarily at another URL and search engines keep the original URL indexed.
