77% OF SITES LOST KEYWORD VISIBILITY AFTER GOOGLE REMOVED NUM=100: DATA

Summary from the TLDR Marketing newsletter

Google's removal of the num=100 parameter has caused widespread drops in reported impressions, rankings, and keyword visibility. An analysis of 319 sites showed 87.7% saw fewer impressions and 77.6% lost unique ranking terms in Google Search Console. Short-tail and mid-tail keywords were hit the hardest. While reports now look weaker, the ‘lost' keyword visibility may largely be scraper traffic that relied on the num=100 parameter.
