Should I return 404 or 410? What&#8217;s better for my &#8220;crawl budget&#8221;? (more from the depths of my inbox)<\/p>\n<p>The 410 (&#8220;Gone&#8221;) HTTP result code is a clearer sign that these pages are gone for good, and generally Google will drop those pages from the index a tiny bit faster. However, 404 vs 410 doesn&#8217;t affect the recrawl rate: we&#8217;ll still occasionally check to see if these pages are still gone, espectially when we spot a new link to them.  <\/p>\n<p>In practice, I doubt you&#8217;ll see a noticable difference at all between 404 and 410, so while it&#8217;s great to use 410 in situations where you&#8217;re sure, with regards to Google search, it&#8217;s not worth spending too much time on that decision or on its implementation.<\/p><\/blockquote>\n<p>\ufeff<\/p><\/div>\n<div
