It's recorded in the HTML5 spec under 4.2.5.1 Standard metadata names, which defines the correct format and parsing: https://html.spec.whatwg.org/multipage/semantics.html#meta-keywords https://html.spec.whatwg.org/multipage/semantics.html#meta-k... So, it's standardized and not deprecated. It has this note though: "Many search engines do not consider such keywords, because this feature has historically been used unreliably and even misleadingly as a way to spam search engine results in a way that is not helpful for users." HTML 4.01 says the following: "This specification does not define a set of legal meta data properties. The meaning of a property and the set of legal values for that property should be defined in a reference lexicon called a profile. For example, a profile designed to help search engines index documents might define properties such as "author", "copyright", "keywords", etc." https://www.w3.org/TR/html4/struct/global.html#h-7.4.4 https://www.w3.org/TR/html4/struct/global.html#h-7.4.4

Ha, I stay corrected! Crawling back under rock to re-read WHATWG and historical W3C docs to fill the voids… Note to self: Apparently, I mentally froze around 2009, so I have some decades to catch on. It seems the breaking point was after 2009 Hixie's WONFIX for adding keywords [0], at a time when both `keywords` and `description` were both swept aside into "MetaExtensions" [1]. The turning point I clearly missed came in 2010 [2] and got resolved through [3].
