A crawl response is basically the response a search engine bot gets from a website while going through it. It is indicated by a response code, which shows the number of attempts made and the problems encountered. Here are a few crawl responses that SEO professionals should know about:
OK (200): Successful Request
This is a positive response code indicating that a website has no major issues and no problems with crawling.
301: Permanent Redirect
When a website is permanently moved, and you redirect users to the desired format of your blog.
A 301 or 308 redirection is recommended in the following cases:
1. Migration of the website
2. Redirecting from HTTP to HTTPS
3. Fixing the www. and non-www. versions of the website
4. Making changes to the URL structure.
302: Temporary Redirect
This redirection response is given to bots when a blog or website is temporarily moved. A 302 or 307 redirect is used when you want to direct the audience to a specific page for a limited time.
1. Seasonal or sales pages.
2. Conducting A/B testing
3. Using feedback pages for a limited period.
304: Not Modified
The bot returns the response code as 304 when a page hasn’t been modified or updated since the last crawl.
404: Resource Not Found
A bot returns a 404 response when it encounters broken links on your website or when a page has been removed without a replacement. This happens when there is no relevant answer to provide for the user’s request.
These responses are positive crawl responses intentionally implemented to enhance website performance and improve user experience.
Now let’s move on to more important crawl responses that require extra attention. SEO specialists and professionals should have knowledge and know-how to address them.
401/407: Unauthorized Access
Secured pages, when accessed from outside the desired location or IP addresses, will return a 401 or 407 crawl response to Google bots, indicating that the page should be blocked from access.
5XX: Server Unavailable
These are server-related errors that occur when a server fails to provide the requested information to the user. A 503 error happens when one or more servers are unable to complete a user query. A 504 response is seen when a query remains unresolved for an extended period, often referred to as a page timeout.
These crawl response codes are commonly encountered when analyzing Web Vitals in the Search Console, performing competitor analysis, conducting website audits, and analyzing backlinks.
Crawling is a fundamental and crucial step to appear in search page results. All the efforts put into SEO optimization are in vain if the page is not crawled. Understanding these crawl response codes will further assist you in analyzing the root cause of issues and methods to resolve them.
