Pages loaded correctly, and styles and JavaScript worked perfectly for users.\u00a0<\/p>\n<p>Yet, in Google Search Console\u2019s inspection tool, the same pages often appeared broken and unstyled.\u00a0<\/p>\n<p>The issue was inconsistent, making it nearly impossible to replicate in front of the dev team.\u00a0<\/p>\n<p>As a new team member still building trust, convincing them there was a deeper problem wasn\u2019t easy.\u00a0<\/p>\n<p>In hindsight, my mistake was not checking the browser console earlier.<\/p>\n<p>Three months later, a single browser console message finally revealed the root cause: a script was loading out of order.<\/p>\n<p>Due to caching, Googlebot sometimes saw the website correctly and other times didn\u2019t, explaining the erratic behavior.<\/p>\n<p>It was a tough reminder that small technical details \u2013 like the sequence of resource loading \u2013 and overlooking an obvious diagnostic step can significantly impact SEO performance.<\/p>\n<p>My key tip: Check your website in different browsers and carefully review the error and warning messages in the console.\u00a0<\/p>\n<p>If you\u2019re unfamiliar with developer terminology, consult an independent expert or even multiple AI tools for explanations.<\/p>\n<h2 class=\"wp-block-heading\" id=\"h-non-existent-urls\"><span class=\"ez-toc-section\" id=\"Non-existent_URLs\"><\/span>Non-existent URLs<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>While investigating those frustrating random 404 errors, I stumbled upon another issue almost by accident.\u00a0<\/p>\n<p>While reviewing Google Search Console\u2019s report on pages discovered but not indexed, I noticed an unusual pattern \u2013 several non-existent URLs appearing under certain sections, marked as duplicate content.<\/p>\n<p>Instead of returning 404 errors as expected, these URLs resolved as normal pages with a 200 status code.<\/p>\n<p>This type of error presents two major risks:<\/p>\n<ul class=\"wp-block-list\">\n<li>From an SEO perspective, search engines treat these URLs as legitimate, potentially indexing irrelevant or duplicate pages, wasting crawl budget, and harming rankings.\u00a0<\/li>\n<li>From a security standpoint, it creates a vulnerability \u2013 malicious actors could generate thousands of random URLs, overloading the server.<\/li>\n<\/ul>\n<p>Unfortunately, this issue is difficult to detect before it becomes a real problem. In my case, I was just lucky.<\/p>\n<p>Don\u2019t wait to stumble upon it. Make sure to:<\/p>\n<ul class=\"wp-block-list\">\n<li>Regularly check whether sections of your site allow non-existent URLs to resolve with a 200 status.<\/li>\n<li>Build a list of key sections and test them monthly with your crawler.
