For Google ranking, the meta keywords tag is dead, and it has been for well over a decade. Google announced publicly back in 2009 that it does not use the meta keywords tag in web search ranking at all, and nothing since has reversed that. So the honest answer to the title is not a definition of the tag, it is a verdict: stuffing keywords into that tag does nothing for your position in Google results. Treating it as a live SEO lever in 2026 is working from advice that expired before many sites you compete with were even built.

The reason it stayed dead is partly that the tag was trivially abused. Site owners crammed it with terms they wanted to rank for, often terms the page had nothing to do with, so the signal was worthless to a search engine almost immediately. Worse, because the tag sits in your page source where anyone can read it, you are effectively publishing your target keyword list for competitors to copy. That competitor-exposure problem is the small but real downside of keeping it: you gain nothing in ranking and you hand your strategy away for free.

Does anything read it at all? A few narrow systems might. Some internal site search tools, certain content management plugins, or niche vertical engines can be configured to look at it, and you may have a specific internal use case where it carries metadata you control. But none of that touches your Google ranking, which is what almost everyone asking this question actually cares about. So for SEO purposes it is effectively dead, with only those edge cases as a footnote rather than a reason to maintain it.

The practical move is to stop adding meta keywords for ranking and stop worrying about whether yours are “right.” Spend that effort on the title tag, the meta description (which can lift click-through even though it is not a ranking factor), and genuinely relevant page content. If your CMS auto-fills a keywords tag, leaving it is harmless, but never treat populating it as SEO work. Pull your attention to the signals Google actually reads, and let the keywords tag rest where it has been for years.
