Understanding Google’s HTTP Status Code Priorities
When delving into search engine optimization (SEO), understanding how Google handles HTTP status codes is crucial. Recently, Google’s Search Relations team shared insights into the HTTP status codes that have a significant impact on SEO during a podcast titled "Search Off the Record." The discussion was particularly aimed at clarifying the categories of status codes that often confuse SEO professionals.
What's Really Happening with 1xx Status Codes?
One of the most surprising revelations was that Google completely disregards 1xx status codes, including newer codes like HTTP 103. Gary Illyes from Google stated, "We are just going to pass through [1xx status codes] anyway without even noticing that something was in the 100 range." For webmasters and site owners, this means that while implementing early hints may improve user experience, it won’t tangibly affect search engine optimization.
The Simplicity of Redirects
Another common misconception is the complexity surrounding redirects. Many SEO practitioners spend a great deal of time debating the best type of redirect to use—be it a 301, 302, 307, or 308. However, Illyes suggests that Google is mainly concerned about whether a redirect is permanent or temporary. He emphasized that for canonicalization purposes, the type of redirect does matter, but ultimately, understanding the basics simplifies the planning process for redirects.
Client Error Codes: What You Need to Know
The 4xx status codes, particularly codes like 404 (Not Found) and 410 (Gone), operate as expected within Google’s crawling framework. According to the podcast, using these codes correctly is essential for optimal website performance. Illyes humorously mentioned the infamous 418 status code, "I’m a teapot," which most SEO experts already know carries no SEO weight—highlighting the quirky aspects of web standards.
Diving Deep: Network Errors in Search Console
Search Console often presents network-related errors that can leave webmasters scratching their heads. Illyes indicates that many of these mysterious issues may stem from deeper layers like TCP, UDP, or DNS settings. He encourages webmasters to explore these areas when faced with network errors, implying that correct technical setups are foundational to SEO success.
What Else Should You Consider?
While the podcast covered several important areas, it notably left out some critical HTTP status codes that impact SEO. Webmasters must stay informed about codes like 503 (Service Unavailable) and 301 (Moved Permanently), as they can directly affect site performance in search rankings. Understanding all aspects of HTTP status codes ensures comprehensive site management and optimized performance.
Final Thoughts on HTTP Status Codes and SEO
Staying informed about how Google processes different HTTP status codes is not just a technical detail; it’s integral to effective SEO and site management. As you develop and maintain your website, keep these insights in mind to ensure optimal performance and user experience.
