Have you been desperately trying to get Google to index all of your websites pages? Constantly revamping your sitemap, updating your content, and resubmitting only to find your stats in Google Search Console barely improving? In a tweet Google’s John Mueller confirmed that Google will never actually index all of your pages and there really isn’t anything you can do about it.
@webrankinfo @methode We never index all pages, so you can'f always fix that. Do you see sites with important ones missing? That'd be a bug.

Unfortunately Twitter still has a 140-character limit on Tweets so we don’t get much detail as to WHY Google doesn’t index all the pages. Even Barry Schwartz over at Search Engine Roundtable has only been able to get Google to index 95% of his website.
