This didn\u2019t make sense.&nbsp;&nbsp; If the site was seeing an improvement in rankings, why are impressions dropping.&nbsp;&nbsp; The following shows this across my and 3 other client sites:<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"653\" height=\"630\" src=\"https:\/\/daveashworth.co\/blog\/wp-content\/uploads\/2025\/10\/gsc_data-1.png\" alt=\"GSC Data\" class=\"wp-image-1778\" srcset=\"https:\/\/daveashworth.co\/blog\/wp-content\/uploads\/2025\/10\/gsc_data-1.png 653w, https:\/\/daveashworth.co\/blog\/wp-content\/uploads\/2025\/10\/gsc_data-1-300x289.png 300w, https:\/\/daveashworth.co\/blog\/wp-content\/uploads\/2025\/10\/gsc_data-1-150x145.png 150w\" sizes=\"(max-width: 653px) 100vw, 653px\" \/><\/figure>\n\n\n\n<p>Further to that, you will see for the most part, clicks have not been affected massively either way, so it was all seemingly a bit odd and didn\u2019t stack up.<\/p>\n\n\n\n<p>Over recent months (years even), I\u2019ve seen a number of shifts in search results due to the inclusion of things like shopping results, AI overviews, video result, image results etc &#8211;

Every time one of these bots or tools loaded a results page with your listing on it, it counted as an impression.<\/p>\n\n\n\n<p>When Google removed &amp;num=100, those automated \u201cimpressions\u201d instantly disappeared. The data now reflects more realistic, human-based visibility, mainly within the first few pages of results.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why_this_caused_impressions_to_drop\"><\/span>Why this caused impressions to drop<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Because Search Console reports an impression whenever your URL appears in search results, removing those deeper-page bot loads meant that all impressions from positions 20-100 effectively vanished overnight.<\/p>\n\n\n\n<p>If your site ranked for lots of longer-tail keywords that appeared low down (page 3, 4, 9, etc.), those impressions are no longer being counted. That\u2019s why you see a sharp drop in total impressions, particularly on desktop (most SEO tools use desktop search results).<\/p>\n\n\n\n<p><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why_average_position_improved\"><\/span>Why average position improved<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Your average position is the mean of all ranking positions where your site received an impression.<br>When all those low-ranking impressions disappeared, only the higher-ranking ones remained \u2014 for example, positions 3, 8, 12 instead of 3, 8, 12, 75, 93, 97.<\/p>\n\n\n\n<p>Mathematically, that makes your average position look better, even though your real rankings haven\u2019t changed.<\/p>\n\n\n\n<p><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_confirm_this_is_the_cause\"><\/span>How to confirm this is the cause<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>You can check a few things to be sure:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Compare desktop vs mobile in Search Console \u2014 the desktop version will show the drop, mobile will look mostly normal.<\/li>\n\n\n\n<li>Look at Google Analytics (GA4) \u2014 if your organic traffic and conversions stayed steady, it\u2019s just reporting noise.<\/li>\n\n\n\n<li>Check the timing \u2014 if the change started around 10-15 September, this aligns exactly with the &amp;num=100 removal<strong>.<\/strong><\/li>\n<\/ul>\n\n\n\n<p><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"In_short\"><\/span>In short<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>This wasn\u2019t a ranking drop or an algorithm change \u2014 it was a reporting correction.<br>Google effectively stopped counting automated, non-human impressions that were never real searchers to begin with.<\/p>\n\n\n\n<p>Your visibility to real users hasn\u2019t changed; the data just looks cleaner now.<\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>In September 2025, many sites saw impressions drop and average position improve in Google Search Console &#8211; a confusing pattern that wasn\u2019t caused by an algorithm update.
