Then the registration function has no idea of what to do with a index.html file and tells you that the MIME-type is not correct.  A quick fix would be to copy the service-worker.js file to the public folder so that when you hit http://domain.com/service-worker.js you see the file in the browser.  Remember to go to ChromeDev > Applications > ServiceWorkers and hit Unsubscribe. in order to remove the errored...

  Install Google Analytics to WordPress Without a Plugin In order for Google Analytics to start tracking your visitors, the tracking code mentioned above needs to be present on every page of your site you want to track user behavior on. Usually, that’s all of them. Here’s how you can achieve that manually.

Most standard themes have a header.php file that is responsible for outputting the site header section. So, you can simply input the Google Analytics code here. However, when you make changes to theme files, be aware that it’s always best to do it in a child theme. Otherwise, they will get lost when you update your main theme. Child themes are super useful in general and you should definitely read up about them. Also, don’t forget to back up your WordPress site when making any changes like this. Once you...

This helps Googlebot discover the location of your site's mobile pages. On the mobile page, add a  rel="canonical"  tag pointing to the corresponding desktop URL. google support two methods to have this annotation: in the HTML of the pages themselves and in  sitemaps . For example, suppose that the desktop URL is  http://example.com/page-1  and the corresponding mobile URL is  http://m.example.com/page-1 . The annotations in this example would be as follows.
