It's common for ClickSambo's click count to differ from Google Ads, mainly because:
Google Ads Filters First: Google Ads automatically filters out many invalid clicks before they appear in your reports and before you're charged.
ClickSambo Sees All Raw Clicks: ClickSambo captures every click that lands on your website for comprehensive analysis, including those Google might later discard.
Different Detection: ClickSambo uses its own advanced algorithms, sometimes catching fraud that Google's initial filters miss.
Timing & Configuration: Real-time data, post-filtering, and potential time zone or tracking setup differences can also contribute.
In essence, ClickSambo shows you the full picture of traffic, including clicks Google may filter out, to help you identify and block more fraud.
