I believe that the question of which this was marked a duplicate seems to be one about the actual HTML tag's max length. I know there is no such max length and instead want to know about how the number of keywords affects SEO

I know that search engines like Google try to detect which webpages are lying by putting in too many keywords in the <HEAD>, but what if I have a webpage where very many keywords apply? Specifically, I noted that in my online résumé I have the following tag:

<META NAME="keywords"    CONTENT="Ben Leggiero,Ben,Leggiero,programmer,programming,developer,Java,C,C++,C#,Objective-C,JavaScript,Ruby,Python,HTML5,CSS3,PHP,XML,XSL,Haskell,Lisp,Prolog,COBOL,Android,Android 4.0,Ice Cream Sandwich,Android 4.1,Jellybean,Android 4.4,KitKat,Android 5.0,iOS,Windows 8,Windows Store,Browser extensions,browser apps,PSP software engineering,TSP software engineering,multiplatform,multiple languages,artist,graphic artist,Graphic Design,Vector,Raster,Photo touchup,photomanipulation,Adobe,Photoshop,Illustrator,CS3,CS4,CS5,CS6,Autodesk,Revit,Maya,3DS Max,Blender,Terragen,Inkscape,GIMP,Ulead,Corel,PhotoImpact,UI,UIX,GUI,TUI,User interface,enthusiast,professional,resume,cv" />

which is 75 keywords. All of these reflect what I consider the most important information in the page, especially since some of it (photo touchup, the full list of CS#, etc) is implied in English but probably not inferred by a crawler. Is this too many? Where's the limit?

Additionally, I heard through the grapevine that modern search engines actually ignore keywords in favor of fancy intelligent parsers. If this is true, how to I attach meta information to text on the page like "CS3,CS4,CS5,CS6" for "CS3-6", or "Android,Android 4.0,Ice Cream Sandwich,Android 4.1,Jellybean,Android 4.4,KitKat,Android 5.0" for "Android 4.0+"?

    @JohnConde The other question seems to be one about the actual HTML tag's max length. I know there is no such max length and instead want to know about how the number of keywords affects SEO – Ben Leggiero Oct 20 '14 at 20:39
  • If you read all of the answer you will know everything you need to know about the meta keywords tag – John Conde Oct 20 '14 at 20:49
  • @JohnConde I read the answer, and it talks about character length, but I'm asking about how the number of keywords affects results. Please, stop disregarding me as a person and actually talk with me instead of dismissing every single thing I do. It makes me feel unwelcome, and that my curiosity is worthless :c – Ben Leggiero Oct 20 '14 at 20:50
  • Straight answer => Any is too many. No known search engine uses Meta Keywords. Nobody can provide any evidence that it's worth wasting time on this particular item. You will get various vague surmises from "SEO Experts" who get money for filling it, but none of them have ever been able to give a straight answer as to what search engine actually uses it. It was dropped long ago as it proved to be a search engine spamming tool. The best use for it is for your competitors to scrape to see what your SEO Marketing focus is, in other words an information leak you might want to close. – Fiasco Labs Oct 20 '14 at 21:00

    Then you need to figure out how to present it on the page so that Google doesn't consider it to be Keyword Stuffing Is it a specification for a product, or just an extraneous list of words in the hope Google presents your content. Maybe you need to figure some sort of tagging system like the Stack Exchanges use. – Fiasco Labs Oct 20 '14 at 21:24
