Lofesa edited a comment on issue #1622: Disable auto-adding PageSpeed query parameter to location header URL: https://github.com/apache/incubator-pagespeed-mod/issues/1622#issuecomment-540671117 Hi @zevnikrok About the link rel="canonical"... these link say to google what the "original" page is. Think about a page, say a list of products and their prices. The page have a url `https://mydomain.com/products` but this page have a parameter to show the product list ordered by price `https://mydomain.com/products/?order=price`, now google bot see 2 url with the same content so penalize this page with a duplicate content issue. If you put, in the html code, a link rel canonical ( `<link rel="canonical" href="https://mydomain.com/products"; />` ) in the page, then google only indexes the "canonical" page ( `https://mydomain.com/products` ) and no duplicate conten issue. I can see you don´t have this in your page. Well, now you have figured out from where the link with `?PageSpeed=noscript` comes and have set the `pagespeed SupportNoScriptEnabled false;` to disable it, but google had these url and try again and again to fecht it.... pagespeed module can´t solve this, has nothing to do on how google do their work to store in cache/ indexing url´s.... But you have options: 1.- In the new Search Console, at the left panel you have an option "Legacy tools and reports", in these option "Removals". With this tool, you can hide the url in search result for a 6 moth time lapse. 2.- As far as you can´t set a robots noindex metatag in the page cause this "deletes" the page from the index and you don´t will that, you need to set nginx to return a 404 - 410 error when a url have the `?PageSpeed=noscript` parameter, these error tell to google that the page is gone so then it deletes the url from their index and cache. 410 is better that 404, cause 410 tell to google that the page is gone consciously, so take less time to delete it. Is not a fast process, take some time that google bot try to fecht the url get the 404-410 error and deletes de url from index/cache. In the server block of the nginx conf you can set some like this: `if ($args ~* (.*noscript.*){ return 410;}` and then wait....
