Are Keywords In The Meta Description Tag Counted In With The Keywords On The Page?
Or are they regarded as a separate entity?
The reason I ask is because I have some keywords in my description meta that I couldn’t work in with the body text, but I need them so that I can use them in my keywords meta. I hear that the keywords meta cannot include words that are not already among the keywords that you’re already using within the body.

Having keywords in your description tag that do not appear in body text is fine as long as you are not spamming words. The Description METATAG has historically been used by engines in at least two ways.
1) To display the blurb with the search result, otherwise it will look to other sources, perhaps may even generate from body text.
2) As keyword weighting and/or relevancy check. This is less used now adays, but the rules are ever changing.
In short, put a good relevant description with the top few keywords from your page, don’t sweat some fringe words. On the other hand if they are important Keywords they need to be in your content.
If you are misspoken and were referring to the META Keywords tag, then placing non related Keywords is probably not harmful, since they are not used anymore for positive benefit, but using them wrong (Spamming) could count against you. Either use it as you are supposed to with a list of strong keywords that are relevant, or leave out altogether.

Google had stopped using Meta keywords a long time back.
Google spiders check you web page and picks the keywords from the page and not from the meta keywords. The reason is years ago when search engines used to display the results based on the meta keywords they have found a large number of spammers using keywords that are not relevant to the site.
Hence, I suggest that you stop wasting your time on meta keywords and instead use the time to have a good and unique content that would be useful to your visitors.
you can put whatever keyword you want on the meta tag but keep in mind that google other major search engines dont look at the kw tag anymore.
meta kw tag has been abused so much and just because its so easy to manipulated, search engines dont consider it as a ranking criteria. best way to focus on your kw would be to use it on your title, description, on the header (preferably in the H1 tag), first paragraph of your body content, and evenly spacing the keyword out throughout the body content. if yuo have any secondary kw,then just add them on your body content. using the kw tag will not do you any good anymore
I recommend to clients to put their keywords in the meta tag but do not believe that Google takes these keywords into account. Google looks at the content of your pages to determine what your site is about. So it really doesn’t matter what you in the meta tags but what you write about.
Google has changed their criteria many times over the past five years which is why I still recommend having the meta tag but today it doesn’t have any weight as far as I can see.
Focus on one keyword phrase and make sure you have relevant content to start to raise the relevancy of your website.
I was not aware of any problem with duplicating body keywords in the meta keywords. All the top level search engines apparently ignore the meta keywords, instead they focus on what the users see, the meta description is mainly used to display a search result summary.
It might be worth having the google keyword tool examine your site to confirm that the correct words are being discovered.
To be specific Meta description is a short summary of your web page, you need to write about the page in short using the targeted keywords. If you want some keywords to appear in the search results, make sure that you use that keyword in the page.
I have never heard that the Meta keywords can’t match your site keywords. Actually i’ve heard the opposite. Your meta keywords should be in your site somewhere to not look spammy.
