how much key word density maximum we use while we creating content its have any limit ? thanks in advance
Keyword density is old hat. Just write naturally. Google is quite clever at figuring out what your site is about. If you focus on keyword density, you're likely to raise a spam flag and turn visitors off.
Your right vinfotech. 3-4% of total content is the limit for usage of keywords. So be carefu in creating your content and make sure it will be a quality one.
The keyword density should be in the range of 2-5%. Also, please ensure that your keywords appear naturally through out your content.
