Real 404 is the correct technical response for non-existent content. Soft 404, on the other hand, is when a 200 is returned while showing a 'not found' message to the user. Redirect issues should be evaluated together with the relevance of the target, chain length, loop, and final HTTP code.
Not found (404)
Soft 404

Real 404 is the correct technical response for non-existent content. Soft 404, on the other hand, is when a 200 is returned while showing a 'not found' message to the user. Redirect issues should be evaluated together with the relevance of the target, chain length, loop, and final HTTP code.
Distinguish between crawling, indexing, canonical, performance or ranking issue.
Compare current HTTP, HTML, header and render output with Google's recorded data.
Verify that canonical, sitemap, internal linking, robots, and redirects point to the same URL intent.
Develop content taking into account that technical suitability is not a guarantee of index or ranking.
Do not redirect all 404 URLs to the home page.
Meaning: The page is not found or appears weak, but returns 200.
Possible cause: Empty product, error template or redirect to homepage.
Meaning: The URL cannot be found on the server.
Possible cause: Deleted content or broken link.
Meaning: Google failed to complete the redirect.
Possible cause: Loop, long chain, broken target, or SSL.
Meaning: The URL is rotating on itself or between two URLs.
Possible cause: HTTP/HTTPS, www, or application rule conflicts.
Meaning: Old URL is being sent to the main page.
Possible cause: Bulk redirect rule.
Meaning: There is a 404 URL inside the sitemap.
Possible cause: Old sitemap or deleted product.
Meaning: Clearly indicates that the content has been permanently removed.
Possible cause: Scheduled permanent deletion.
Meaning: Not every 404 is an SEO error.
Possible cause: User or bot may request a random URL.

curl -sI https://example.com/old-url | head -n 15
Displays the first HTTP response.
curl -sIL https://example.com/old-url | grep -iE '^HTTP|^location:'
Displays all redirect steps.
curl -sS -o /dev/null -w 'Code:%{http_code} Redirects:%{num_redirects} Final:%{url_effective} Total:%{time_total}\n' -L https://example.com/old-url
Final URL, code, and redirect count displays.
curl -s https://example.com/sitemap.xml | grep -oP '(?<=<loc>).*?(?=</loc>)' | while read u; do c=$(curl -s -o /dev/null -w '%{http_code}' "$u"); [ "$c" != 200 ] && echo "$c $u"; done | head -n 80
Displays non-200 URL examples in the Sitemap.
grep -RFn '/eski-url' /var/www/html 2>/dev/null | head -n 40
Finds old URL references in special projects.
curl -s -o /dev/null -w '%{http_code} %{url_effective}\n' -L https://example.com/rastgele-var-olmayan-url-987654
Tests whether a random URL redirects to the homepage instead of a 404.
Deleted products, changed slugs, and the SEO plugin redirect module should be checked.
For a route without a router, a real 404 status should be sent, but the error HTML should not be displayed.
Old product slugs should be meaningfully matched to new product or related category.
After removing the technical barrier, the re-crawl and re-evaluation period by Google varies depending on the URL, site, and issue type; there is no certain time or index guarantee.
No. The request is only a re-crawl signal; if technical issues, canonical, content quality, and internal linking problems are not resolved, the result may not change.
No. It serves as a helper signal for sitemap discovery and canonical preference; it does not guarantee crawling and indexing.
The plugin facilitates meta and sitemap production, but does not solve content, server, internal link, canonical, and Search Console analysis on its own.
Google does not specify a technical character limit; the result view may be shortened depending on the device and query. The title should be short, descriptive, and unique.
Google has removed the rich results feature from the FAQ section as of May 7, 2026. The FAQ section can be kept for user benefit, but there is no guarantee of rich results.
No. The guide helps to systematically solve technical and content issues; ranking depends on competition, quality, authority, user demand, and Google systems.
We examine indexing, sitemap, canonical, Core Web Vitals, schema and organic traffic problems together on WordPress, special PHP and WISECP infrastructures.
