Accessibility
Usually, developer tools are already installed in browsers and most of them include a console: this provides information about the running page.
In the console, messages are recorded by the developers who created the page or by the browser, and they have a level of importance: Verbose, Info, Warning or Error. If you see an error message, it means that there is a problem on the page that needs to be resolved.
Browser errors logged to the console are notified by SeoChecker.
It's important for your page to solve them, in order to make it run as you and your users expect.
