The Google Search Console page you provided shows different reasons why certain pages on your website are not being indexed by Google. Here’s an explanation in simple language:
Not found (404)
This means that there are 64 pages on your website that are returning a 404 error, which indicates that the page doesn’t exist or can’t be found. Google won’t index these pages because they are essentially broken links.
Excluded by ‘noindex’ tag
There are 1,469 pages on your website that have a “noindex” tag, which instructs search engines not to index those pages.
Page with redirect
There are 570 pages that are redirecting to another URL, which can cause confusion for search engines, so they are not being indexed.
Duplicate without user-selected canonical
There are 440 pages that are duplicates of other pages on your site, and you haven’t specified which version should be indexed as the canonical (main) page.
Alternate page with proper canonical tag
There are 52 pages that are alternate versions of other pages, but you have correctly specified the canonical page to be indexed.
Soft 404
There are 34 pages that are returning a soft 404 error, which means they may be empty or have very little content, so Google doesn’t consider them valuable enough to index.
Blocked due to other 4xx issue
There is 1 page that is returning a 4xx error, which is a client-side error that prevents Google from indexing it.
Crawled – currently not indexed
There are 18 pages that Google has crawled (visited) but has chosen not to index for various reasons.
Discovered – currently not indexed
There are 61 pages that Google has found but hasn’t crawled or indexed yet.
Blocked due to access forbidden (403)
There is 1 page that is returning a 403 error, which means that Google is being denied access to it and can’t index it.
In summary, these reasons indicate various issues with the pages on your website that are preventing Google from indexing them, such as broken links, duplicate content, lack of content, redirect issues, and access restrictions.
