Keywords and SEO. The facts
The only way to lead the online market today is undisputedly the SEO. SEO guarantees the sites top rankings on the major search engines result pages. Rankings on the major search engines generate huge traffic to your website. The most important part of the whole SEO process is determining the keywords and it is the only part that is always avoided by most of the users. The negligence to the keyword will never let you be there at the rankings at SERP.
The senseless use of your keywords can also create a hazardous condition for your site as it can push you in the black list of the search engine databases. In other words your site can be spammed by the search engines and then it would be very tedious job to regain the position as it was earlier.
The best approach to use the keywords is to optimize the page for not more than 3 keywords. The density of the keywords in the content should not exceed more than 5 percent. The use of “and” should be avoided in keywords, as they are considered as the stop word. Search engines try and avoid such words. The repeated use of keywords is also not appreciated by the search engines.
One more thing to do with keywords is to use the keywords in TITLE of the site as well as in the description tag. The density of keywords in the TITLE should not be very dense as it will not be appreciated but penalized.
