wbAMP getting started guide
Just after installation, the wbAMP system plugin is enabled, but the plugin itself has no effect on your site: you first need to add some rules to let it know which pages should have AMP versions.
wbAMP has a Development mode, that lets you setup AMP on your site, but does not tell Google you have AMP pages. Once your AMP pages are fully tested and valid, you can switch to Normal mode, and let Google discover your AMP pages. Just don't forget to enable Normal mode after testing!
Step 1: Configure Joomla!
As a reminder, wbAMP requires that SEF URLs are enabled and working on your site, whether using the native Joomla SEF system, or sh404SEF. Once SEF URLs are working on your site, you can move forward with wbAMP.
Step 2: Configure wbAMP
You can access wbAMP parameters through the Joomla! plugins manager. Search for the wbAMP system plugin and open it. This initial setup is presented with more details on this page.
You must verify that your pages are valid AMP before letting search engine crawl and index them.
Google provides tools to test your page and find any error. Their usage is described on this page. Use them, because invalid pages will simply not be indexed.
