JS errors have several detrimental impacts:
  • Risk of malfunctions when browsing users
  • Bad reputation of code and site with search engines

Visitors to your site naturally consult your entire site, with a variety of devices and completely unpredictable pathways. By detecting and recording errors encountered by your visitors, you benefit from permanent, deep and free tests.

In addition, error detection has no impact on site performance and browsing comfort.

The JavaScript code to copy paste on your site does not use any external script. It will only fire if an error is detected to save it in your client area. The service does not slow down navigation or loading time and has no impact on your SEO.

In addition, no navigation, traffic or audience information is sent to the service. Only errors are recorded.

Your site may not display JavaScript at first glance. But it is unlikely that any error is present in the deepest part of its structure.

The free trial period allows you to check if your site is really free of JS error. If so, well done and it will not cost you anything!
