Why did my Google Ads campaign suddenly stop performing even though I didn't change anything?

Direct Answer: Sudden performance drops are often caused by bot traffic contamination and pixel poisoning rather than market shifts. Price scrapers and inventory bots simulate high-intent behavior and trigger your tracking pixel, misleading the ad algorithm. BotRefund detects these sessions in real time and...

Direct Answer: Automated browsers rely on patching browser APIs to hide their automation. But patches often introduce mismatches that a real browser wouldn't have. The Voice Brand Check catches these inconsistencies. Even when a bot tries to mimic human behavior, another angle of the...

Direct Answer: Automation tools such as Playwright often modify browser APIs to look like a normal user. Those modifications can be inconsistent when checked from another angle, creating detectable mismatches. BotRefund's Playwright Init Scripts check is designed to spot that kind of broken patch....

Direct Answer: They often build partial or placeholder implementations that do not hold up when checked from multiple angles. BotRefund's Background Navigation check looks for these internal inconsistencies. Then it cross-checks the anomaly with independent browser, network, device, and behavior data. That is why...

Direct Answer: Real people produce imperfect, varied interactions—they pause, hesitate, and move naturally. Automated scripts can send clicks and scrolls, but they struggle to reproduce the timing and hesitation of a real user. BotRefund's Rapid Tab Blurs check captures this difference. It's just one...

Direct Answer: Automation tools try to hide by patching browser APIs, but those changes can break when the browser is checked from another angle. BotRefund's Iframe Webdriver Leak check is designed to catch that break. This signal is only one of 106 checks, so...

Direct Answer: Automation tools often patch or hide browser APIs to avoid detection, but those changes can break when the browser is checked from another angle. The CDP Stack Trace Trap is one such angle. BotRefund uses it as an independent signal in a...

Direct Answer: Automation toolkits often create shortcuts or remnants that a normal user's browser would not have. These artifacts are left behind because the browser was launched programmatically rather than manually. BotRefund's asset starvation check detects this mismatch and uses it as one piece...

Direct Answer: Automated browsers often patch or hide browser APIs to look more like a real user. But those patches can be detected when the same APIs are checked from another angle. BotRefund's toString Patch Shadow check is designed to catch that mismatch. It...

Direct Answer: Because they rarely expose complete, internally consistent browser capabilities. A partially spoofed browser may show missing, simplified, or inconsistent details when checked beyond the surface. BotRefund uses History Evasion as a clue that a visit may be automated, but confirms it with...

Direct Answer: Automated browsers often patch or stub browser APIs to hide their automation, which can leave incomplete or inconsistent navigation timing data. BotRefund's check looks beyond the surface to find these stubs. Even sophisticated bots may miss this detail. The signal then becomes...

Direct Answer: Automated browsers often run in virtual machines or spoofed profiles that claim hardware details that do not match real behavior. Audio latency, GPU, fonts, and processor data can expose those mismatches. BotRefund's Audio Latency Drift check captures this. A normal browsing session...

Direct Answer: Automation tools often patch or hide browser APIs to make an automated browser look normal. Those patches can break when the browser is checked from another angle, creating mismatches. BotRefund's Permission Lie check is designed to catch this type of inconsistency. It...

Direct Answer: Because a normal browser reports hardware, graphics, fonts, and operating-system details that naturally fit together. Automated browsers and virtual machines often spoof one part but leave mismatches in GPU, font, audio, or processor behavior. BotRefund uses those mismatches as one of 106...

Direct Answer: Automated browsers usually hide their automation by patching the browser APIs. Those patches can work for one check but break when the detection tool looks at the browser from a different angle. The Hex-Edited CDP Leak check is designed to see that...

Direct Answer: Automated browsers often patch or hide browser APIs to avoid detection, but those patches can break when checked from another angle. The Math Rounding Matrix check looks for that kind of mismatch, which a real browsing session does not normally create. BotRefund...

Direct Answer: Automated browsers often lack the full set of assets that a normal user's browser would load, because they are stripped down for efficiency. This creates a mismatch that a real browsing session does not normally produce. BotRefund uses this mismatch as one...

Direct Answer: Automated browsers often run in virtual machines or spoofed environments where the claimed hardware does not match the actual rendering behavior. Real browsers on normal devices tend to have audio, GPU, font, and operating-system details that fit together. BotRefund uses this mismatch...

Direct Answer: Automated browsers often use scripts that patch or replace browser APIs to hide their automation, which can leave behind stubbed or incomplete navigation timing data. BotRefund detects these stubs as a sign that the browser may not be a real user. However,...

Direct Answer: Automation tools often patch only the surface APIs and leave other parts incomplete. When BotRefund checks beyond the surface, it finds missing or simplified capabilities that a real browser would expose consistently. This mismatch is reflected in the Chrome API Stub signal.
