Alternate Page with Proper Canonical Tag:

• Ensure that each page on your website has a unique URL.
• Implement the canonical tag on each page to indicate the preferred version of the page. The canonical tag should point to the canonical URL of the page.
• Double-check that the canonical URLs are set correctly and not pointing to incorrect or alternate versions of the page.
• Submit an updated sitemap to Google Search Console to help Google understand the structure of your website.

Duplicate Pages without User-Selected Canonicals:

• Identify the duplicate pages on your website.
• Decide on a preferred version of the page.
• Implement the canonical tag on the duplicate pages, pointing to the preferred version.
• Ensure that the preferred version of the page has a self-referencing canonical tag.
• Use 301 redirects to redirect users and search engines from the duplicate pages to the preferred version.

Pages with Redirects:

• Review the pages that have redirects and identify the reason for the redirects.
• If the redirects are necessary, ensure that they are implemented correctly.
• Use 301 redirects for permanent redirects and 302 redirects for temporary redirects.
• Update any outdated or incorrect redirects.

Discovered - Currently Not Indexed and Crawled - Currently Not Indexed:

• Make sure that the pages are accessible to search engines and not blocked by robots.txt, meta tags, or any other restrictions.
• Check for any server errors (e.g., 5xx status codes) that might be preventing Google from indexing the pages.
• Improve the internal linking structure of your website to ensure that the pages are discoverable.
• Submit an updated sitemap to Google Search Console to help Google crawl and index your pages.

Not Found (404) Errors:

• Identify the pages that are returning a 404 error.
• Determine if the pages should exist or if they are no longer needed.
• If the pages should exist, fix any broken links or incorrect URLs that are causing the 404 errors.
• Use 301 redirects to redirect users and search engines from old URLs to relevant and existing pages on your website.
• Monitor and regularly check for new 404 errors to address them promptly.
