Could you please tell me that what is the maximum length for meta keywords?
FYI, meta keywords have no effect on SEO whatsoever.
There is no official length requirement but generally you'll see people mention anywhere from 100 to 255 characters. Just be sure to put in the words that match your page's content and don't worry about anything else.
Meta Keywords doesn't make any improvements in SEO, use
Meta Description instead.
FYI, different search engines show different number of characters of meta description and title tags.
Anything you want, there is no limit.
<TITLE> - As shorter is better for your keywords. I use 3 - 6 words and separate them with "|".
<title>Keyword Phrase 1 | Keyword 2
Before I filled this meta with keywords and tried to make it interesting for users but now I leave this meta tag empty and it works not bed. I mean Search Engine generates the description automatically and yanks the best snippets.
I don't pay attention on it. I lost the value now.
Just as an FYI - Google no longer places any SEO emphasis on the Keyword meta-tag.
Have a look at these videos from Matt Cutts, the head of Google's Webspam team:
- Google does not use the keywords meta tags in web ranking
- Should I spend time on meta keywords tags?
- How much time should I spend on meta tags, and which ones matter?

Why are you even considering this question, are you doing SEO for a local search engine that uses them? Please tell us your reason behind the choice so that we can help you more.
As for the length, put any amount you wish - it really does not matter if there are 3 or 333 words in it.
The question asked no longer makes any sense in the current environment.
Google and all other major search engines like Yahoo, Bing have disqualified the Meta keyword tag long before.
So even if you're adding the meta keyword tag in your webpages, Google and all other search engines are never going to take a look at that meta and you are never going to get any SEO benefit out of it.
So it's better to concentrate on Title, Description, Body content of the webpage to make SEO work for you.
Please go to Youtube and search with "matt cutts meta keywords". See this Google webmaster page for some meta tags Google supports. The "keywords attribute" section here on wikipedia pretty nice sums up all there is to say about it.
In general: The most important search engines mostly ignore it, so don't waste time with it. As others noted, there is no official length limit, but if your keyword list has as much words as your main content it might look spammy ;-)
7 to 8 general keywords with comma separated is good to put on all pages of your site.
Some peoples put huge list which is over optimization. Keywords must be related to your content or meta description.
There is no limit of meta keywords.
Why you are wasting your time in creating meta keywords tag to your website or blog. Note that google doesn't use meta keyword tags for ranking.
