We don't think there's any value in the meta keywords anymore since both Google and Bing mentioned it quite some time back that meta keywords will be completely ignored.

Here's a link which clearly explains it: https://webmasters.googleblog.com/2009/09/google-does-not-use-keywords-meta-tag.html

Please note that going forward we will not be taking requests for meta keyword changes, since they are no longer taken into consideration by any reputed search engine.

If you have reasons to believe that the keywords are still needed, please share the same with us.
