Response code 406

by

The “406 Response Code” error is a problem related to the indexability of a web page. When a search engine attempts to crawl and access a page on a website, it returns this HTTP 406 error code.

This indicates that the server cannot fulfill the search engine’s requests due to an issue with the site’s content or configuration.

The “noindex” tag is a directive used in the HTML file or the robots.txt file of a website to instruct search engines not to index that page.

When a page has the “noindex” tag, search engines exclude it from their indexes, meaning it won’t appear in search results.

There are a few possible reasons why a page might be marked as “not indexable” and trigger the 406 error

  1. Incorrect Configuration: It’s possible that the website has an incorrect setup in the robots.txt file or HTML file, preventing search engines from accessing the page.
  2. Accidental “noindex” Tags: In some cases, “noindex” tags might be accidentally added to pages, either during a site update or due to a coding error.
  3. Server Issues: There could be server problems affecting the ability to properly deliver pages to the search engine, resulting in the 406 error.
  4. Duplicate Content: If a page’s content is identical or very similar to other pages on the site, some search engines might decide not to index it to avoid duplicate content issues.

Possible Solutions

  1. Check the robots.txt File and “noindex” Tags: Ensure that the robots.txt file and “noindex” tags in the HTML code aren’t blocking the indexing of the page. If necessary, remove or modify these directives to allow search engines to access the page.
  2. Review Server Configuration: Verify if there are server issues causing the 406 error. Make sure the website is properly responding to search engine requests.
  3. Fix Duplicate Content: If the page’s content is similar to other pages on the site, consider reviewing and improving the content to make it more unique and relevant.
  4. Update the Sitemap: Ensure that the page is included in the site’s sitemap so that search engines can find it and index it correctly.
  5. Request Reindexing: After making the necessary corrections, use Google’s search tools to request a reindexing of the page and notify search engines about the changes made.

In conclusion, the “406 Response Code” error and the “not indexable” status indicate that there are issues preventing search engines from properly indexing a page.

Identifying and addressing the possible causes mentioned above will help resolve this issue and allow the page to be properly indexed, improving visibility and site performance in search results.
