Fake clicks or views can happen when bots are involved. One way to spot them is by checking for high traffic numbers with no real engagement like low time on site or no conversions. You can also use tracking tools that help show user behavior and IP activity. If many clicks come from the same IP or from locations that do not match your targeting, that could be a sign. Filters can be added to your tracker to block these patterns. What other things can help stop wasted spend on fake clicks or views?
