Takeaways

• 😀 HTTP status codes are three-digit numbers that servers return when browsers or search engines request a page.
• 😀 The most important HTTP status codes for SEO are 2xx (success), 3xx (redirection), 4xx (client errors), and 5xx (server errors).
• 😀 A 200 OK status means the page was successfully requested and can be indexed by search engines.
• 😀 A 301 redirect (permanent) should be used when a URL permanently moves to another location, transferring SEO value to the new page.
• 😀 A 302 redirect (temporary) does not pass SEO value and is best used for temporary moves.
• 😀 Pages with a 4xx status (such as 404 Not Found) will not be indexed, so you should fix or redirect them to avoid wasting crawl budget.
• 😀 A 410 Gone status indicates that content is permanently gone and should be used when you intentionally remove a page from your site.
• 😀 5xx server errors (like 500 Internal Server Error) can harm SEO by causing search engines to temporarily slow down crawling.
• 😀 A 503 status means the service is temporarily unavailable, often due to server overload or maintenance, and should not impact SEO significantly if resolved quickly.
• 😀 Pages returning a 200 OK but containing no content or error messages may be considered as problematic by search engines, so proper redirects or error handling is important.

Q & A

What are HTTP status codes and how do they work?

HTTP status codes are three-digit numbers that a server returns when a browser or search engine crawler requests a page. They indicate the result of the request and help determine if the page was successfully processed, redirected, or encountered an error.

What is the significance of the 2xx status code, especially 200 OK?

The 2xx status code, specifically 200 OK, indicates that the server successfully processed the request and the content is available for indexing. This is the status you want to see for pages you want search engines to index.

What is the difference between 301 and 302 redirects in SEO?

A 301 redirect indicates a permanent move, passing SEO value from the old URL to the new one. A 302 redirect is for temporary moves and typically does not pass SEO value, meaning search engines might not index the new URL as effectively.

Why is a 404 error problematic for SEO?

A 404 error means the server cannot find the requested resource. Having too many 404 errors can impact a site's crawl budget and lead to pages being removed from search engine indexes.

What does a 410 status code indicate, and when should it be used?

A 410 status code means the content is gone permanently, and this absence is intentional. It should be used when a page is permanently removed and you want search engines to stop indexing it, especially if the page had no significant SEO value.

What impact do 5xx server errors have on SEO?

5xx server errors, such as a 500 internal server error, indicate that the server failed to fulfill a valid request. These errors can be harmful to SEO if not resolved quickly, as they prevent search engines from accessing and indexing content.

How should a site handle a 503 status code during maintenance?

A 503 status code means the service is temporarily unavailable, usually due to maintenance. It signals search engines to come back later, without negatively impacting rankings, as long as the issue is temporary.

What is the role of redirects in SEO when content is moved or removed?

Redirects, particularly 301 redirects, help transfer SEO value from an old URL to a new one when content is moved. For pages that are permanently removed but had rankings or backlinks, a 301 redirect can pass those SEO benefits to another relevant page.

How can a 404 error negatively impact a website’s SEO budget?

Having too many 404 errors on a site can waste the crawl budget, as search engines spend time trying to access non-existent pages. This reduces the overall efficiency of the site's SEO efforts, as search engines may focus on pages that don't contribute to the site's ranking.

What should be done if a page that should not be indexed shows a 200 OK status?

If a page that shouldn’t be indexed still shows a 200 OK status, it might be worth considering a 301 redirect to another relevant page or setting the page to return a 410 status code to indicate that the content is permanently gone and should be removed from search engine indexes.
