On page keywords

[tradereader]

as my suggestion u have to use 10 keywords in on page keywords.
and in those 10 keywords 3-4 keywords must be in title..

Personally, I wouldn't recommend using the keywords any more than 3 times. But there are factors to take into consideration, such as how many words are in your article/blog post.

first of all it depends on the no.of characters in keywords whether they are 2 phrase  or 3 0r 4 phrase words
Second use those in meta description works a lot other than title tag .Definitely use them in content as well other wise they would not give any results Do proper seo also

You should use no more 2% keywords and at least 300 words in each page.

[Vinil]

ideal keyword density must be 3-4% only

use 60 to 80 chars in your site meta Title .........and meta description should be in 160 to 200 char is limit ,,,,

Stand it better on the page listed in Google in a way that can develop and implement a guest to optimize a web page. Google is not always a need to focus on their own Web pages that are appropriate for application processing. Many organizations for the purpose of fully document the on-page optimization can change the way but it is not moral to do can hurt performance.

How many keywords should I use on a page?

You can target 3 to 4 keywords per page of your website.

It depends upon your content, if you have small piece of information then less keywords otherwise more keywords. Actually the keyword density should be nearly 4-5% is efficient.
