SEO-series | Ep. 2. | HTTP Status Codes

Welcome to Off The Bench, the podcast for marketeers in deeptech, SaaS, or ambitious SMEs with small marketing teams. We are 6th Man. A marketing team on demand! HTTP status codes are three-digit responses that servers send back to browsers (or bots) to indicate how a request was handled. They’re like the internet’s way of saying, “Here’s what happened with your request.” They help marketers, developers, and SEOs diagnose site issues, optimize crawl efficiency, and understand how users (and Google) interact with a website. Each status code falls into one of five categories, based on the first digit: 1xx – Informational: The request was received and is being processed (e.g. 100 Continue). 2xx – Success: The request was successful (e.g. 200 OK, 201 Created). 3xx – Redirection: The resource has moved — the client should go elsewhere (e.g. 301 Moved Permanently, 302 Found). 4xx – Client Errors: The request was invalid or can’t be completed (e.g. 404 Not Found, 410 Gone). 5xx – Server Errors: The server failed to fulfill a valid request (e.g. 500 Internal Server Error, 503 Service Unavailable). While HTTP codes themselves don’t directly change your ranking, they strongly influence how search engines crawl, index, and trust your site: 200 (OK): The ideal response — content is accessible and indexable. 301 (Moved Permanently): Passes most link equity and should be used for permanent redirects. 302 (Found): Temporary — use sparingly; Google may not transfer link signals. 404 (Not Found): Fine for genuinely missing pages, but excessive 404s waste crawl budget. 410 (Gone): Tells Google the page is intentionally removed — helps clean up the index faster. 500/503 Errors: Harm crawlability and user trust. Persistent issues can impact rankings. Migration Mistakes: Always check redirects after domain or URL structure changes. A missing 301 chain can cost valuable link equity. Soft 404s: Pages returning 200 OK but showing “Not Found” confuse search engines — fix them with proper 404 or 410 codes. Redirect Loops: Infinite redirect chains block crawlers — test with tools like Screaming Frog or Ahrefs Site Audit. Server Reliability: Frequent 5xx errors signal poor hosting or resource overload. Monitor uptime closely. Always use 301 for permanent redirects and 302 only for short-term tests. Don’t redirect everything to the homepage — preserve topical relevance. Use server logs to identify crawl errors that Search Console might miss. Regularly audit HTTP responses to ensure a clean, crawlable site. 🎙️ In this episode, we break down what HTTP status codes really tell you — from invisible crawl issues to migration traps — and how mastering them can make your site faster, cleaner, and more trustworthy in the eyes of Google.
