  • Send search queries from robots, software, automated services or search scraper.
  • Using programs that send queries to Google to see how a website or web page ranks on Google.

  • Using third-party browser extensions.
  • Perform Google searches on a shared network.
  • You use VPN or Proxy services.

How Do I Fix Google Keeps Asking To Complete Image Captcha Issue?

As we all know, the “Unusual traffic” error is displayed when Google detects that a user is automatically sending traffic.

In addition to the error, you will also see an option asking you to confirm that you are not a robot. You can tap the ‘I am not a robot’ to remove the error message.

You’ll be prompted to solve an image captcha if you don’t see the “I’m not a robot” option. Pass the test, whichever is displayed, to resolve the “Unusual Traffic” error.

So if you use the Google keeps asking to populate the Image Captcha problem, you need to disable the VPN or proxy services you are using.
