Google Keeps Asking To Fill Image Captcha? 7 Ways to Fix it

If you use Google’s search engine to search the web, you may have encountered the ‘Our system has detected unusual traffic from your computer network’ error message.

Have you ever wondered what the ‘Unusual Traffic’ error on Google means and how you can resolve it? When the error appears, you are asked to verify the captcha.

  • Sending searches from robots, software, automated services, or search scraper.
  • Using programs that send searches to Google to see how a website or webpage ranks on Google.

So, if you are doing these two things, you have a reason. But, apart from Google’s consideration, other factors trigger the ‘Unusual traffic from your computer network’ error. Here are some of them.
