Which queries caused your website to appear in search results? Which queries result in more traffic to your website than others? Some years ago most search engines decided to hide keywords from the referrer urls, which made it impossible for web analytics tools to report reliable keyword statistics and answer these questions. Search Keywords Performance Monitor is a plugin created by InnoCraft, the makers of Matomo (Piwik), which lets gain those powerful insights and see all your keywords used by users directly into a new Matomo Search Keywords report.
Your Search keywords data will be imported every day into your Matomo Analytics (formerly Piwik Analytics) and you will be able to access very valuable SEO and insights into your Search Keywords.
