What a traffic checker can't see
Direct, referral, social and email visits. SpringBrand's estimates come from search data (Ahrefs and DataForSEO). It does not connect to Similarweb or other clickstream panels, so it does not report total visits, bounce rate or time on site.
For paid search, ask for the domain's Google Ads keywords instead (Semrush data), or use the ad spy tool to see the ads themselves. For a site you own, Google Search Console and your analytics are the source of truth. A checker is for the sites you can't log in to.
