These status codes are classified according to the type of message they return. Some of the most common are :<\/p>\n<ul>\n<li>200 OK: this code indicates that everything has been done successfully;<\/li>\n<li>301 Moved permanently and 302 Found to indicate that the URL has been <strong>modified permanently or temporarily respectively<\/strong>;<\/li>\n<li>401 Unauthorized for unauthorized access;<\/li>\n<li>403 Forbidden when the client does not have access rights;<\/li>\n<li>404 Not found: by far the most common response. It occurs when the<strong> resource has not been found by the server<\/strong>. This can happen, for example, when a plugin has been updated or a URL has been modified;<\/li>\n<li>500 Interval server error and 503 Service unavailable to indicate a server error.<\/li>\n<\/ul>\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column custom-cta is-layout-flow wp-block-column-is-layout-flow\">\n<p class=\"title wp-block-paragraph\">Got an SEO question?<br>G\u00e9raldine can help<\/p>\n\n\n\n<p class=\"subtitle wp-block-paragraph\">5 years of SEO expertise<\/p>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button btn-seo custom-btn\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/www.seo.fr\/en\/contact-us\">Find out more<\/a><\/div>\n<\/div>\n\n\n\n<figure class=\"wp-block-image size-full cta-image\"><img decoding=\"async\" width=\"251\" height=\"312\" src=\"https:\/\/www.seo.fr\/wp-content\/uploads\/2023\/03\/cta-geraldine.png\" alt=\"\" class=\"wp-image-26893\" srcset=\"https:\/\/www.seo.fr\/wp-content\/uploads\/2023\/03\/cta-geraldine.png 251w, https:\/\/www.seo.fr\/wp-content\/uploads\/2023\/03\/cta-geraldine-241x300.png 241w\" sizes=\"(max-width: 251px) 100vw, 251px\" \/><\/figure>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<h2 class=\"wp-block-heading\" id=\"h-404-error-what-impact-will-it-have-on-your-visibility\">404 error: what impact will it have on your visibility?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A 404 error indicates that the URL is incorrect or that the page never existed. Either way, neither the user nor the search engine can access the content.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Too many 404 errors can affect a site&#8217;s visibility in the SERPs. Search engines, like Google, focus on user experience (UX). An inaccessible page obviously doesn&#8217;t help. It is therefore entirely logical that the SEO rating given to a site with too many 404 errors should be <strong>downgraded<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, 404 errors are not inevitable, and can easily be detected using the appropriate tools and plugins. Once a 404 has been detected, there are various methods for correcting it, including a 301 redirect or a modification to the htaccess.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To identify any 404 errors on your site and measure the impact on your natural referencing, contact the <a href=\"https:\/\/www.seo.fr\/en\/seo-information\/seo-expert\">SEO.fr<strong> <\/strong>team<\/a><strong> for a diagnosis<\/strong>.<\/p>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Whether it&#8217;s a 404 error or a 500 error, website publishers and users alike have all been confronted with such messages when trying to consult a website.
