meta-tags

What has changed with <meta name="robots" content="index,follow"> meta tag? I use HTML5 and W3C validator marks my page as invalid. There is robots meta name allowed in http://wiki.whatwg.org/wiki/MetaExtensions . Exact validator error: Bad value robots for attribute name on element meta : Keyword robots is not registered. unor The validator is wrong. The robots name is registered according to HTML5’s rules , so you can use it. You’ll probably see the same problem with all other registered names, too (e.g., with the google name ). 来源： https://stackoverflow.com/questions/22100619/w3c-validator

According to this update... https://developers.facebook.com/blog/post/2013/06/19/platform-updates--new-open-graph-tags-for-media-publishers-and-more/ ...I thought article:publisher (with page ID or URL) would put a like button for the representative page when shared links are posted to walls? The debugger seems to think differently... what am I missing? Debugger info: Object at URL 'http:// domain.com/post/' of type 'article' is invalid because the given value 'http:// www.facebook.com/mypage' for property 'article:publisher' could not be parsed as type 'profile' article:publisher is for

I am new to Puppeteer, and I am trying to extract meta data from a Web site using Node.JS and Puppeteer. I just can't seem to get the syntax right. The code below works perfectly extracting the Title tag, using two different methods, as well as text from a paragraph tag. How would I extract the content text for the meta data with the name of "description" for example? meta name="description" content="Stack Overflow is the largest, etc" I would be seriously grateful for any suggestions! I can't seem to find any examples of this anywhere (5 hours of searching and code hacking later). My sample
