I’m actually big fan of this wordpress plugin despite the bugs. The authors of this plugin I can tell have been working hard in fixing existing bugs and there are a lot of them, not an easy task. As a developer myself I know how wild code can get, so I give these guys mad respect and credit.
Recently I was tasked with removing this plugin for a site. Disabling and removing the plugin was just the first step. The final step was to implement a redirect that would automatically redirect these amp urls to it’s respective non-amp url – leaving this as-is would be bad for SEO. And the client would not be happy to see their google rankings go down. So let’s take care of this.
