Deciphering the Impact of HTTP Status Codes on SEO: What Google Cares About and Ignores
Nadia Gastrom | | 2 min read
In the complex world of Search Engine Optimization (SEO), every detail matters. Among these, HTTP status codes play an essential role in determining a website’s visibility and ranking on search engine results pages (SERPs). According to a recent article published by the Search Engine Journal, Google takes certain HTTP status codes into consideration when analyzing a website, while others are largely ignored.
HTTP status codes are server responses to a browser’s request to view a particular page. These codes inform the server whether the requested page is accessible, moved, or not found. The different categories of status codes include the successful 2xx, redirection 3xx, client error 4xx, and server error 5xx.
However, not all these status codes are treated equally by Google’s algorithms. Google, the world’s most popular search engine, only cares about a select few of these codes when it comes to SEO.
According to the article, Google’s algorithms pay close attention to status codes that indicate server errors (5xx), client errors (4xx), and redirects (3xx). These status codes can significantly impact a website’s visibility on Google SERPs. For instance, a 404 (Not Found) or 410 (Gone) status could lead to the webpage being removed from Google’s index, while a 301 (Moved Permanently) or 302 (Found) status could result in the transfer of page ranking to the new URL.
On the other hand, Google disregards certain HTTP status codes. These include 100 (Continue) and 102 (Processing) status codes, which are part of the informational 1xx category. The Search Engine Journal article explains that Google’s crawlers don’t take these codes into account because they don’t affect the accessibility or functionality of a webpage.
Understanding which HTTP status codes are significant for SEO is essential for website owners and SEO professionals. Regularly monitoring these codes can help diagnose and fix potential issues that could negatively affect a website’s performance on Google SERPs. It’s also vital to ensure that redirects are properly implemented and that errors are promptly addressed to prevent loss of visibility and ranking.
In conclusion, while HTTP status codes may seem like minor technical details, they play a crucial role in SEO. Knowing which ones Google cares about – and those it largely ignores – can make a significant difference in how a website performs in search results. As such, these codes should not be overlooked in any comprehensive and effective SEO strategy.
