A good article with keywords should lay down information, tips or tricks, or the suggestions to the contents, and should also be easy for the readers to understand. Using too many keywords in articles does not seem normal. Except that, articles with too many keywords are difficult to read and understand.
The choice of the common keywords is likely to have the consequence that the article will be lost among all the other contents available on the internet. Using specific keywords is the best way to optimize results of the search engines.
An article which employs keywords which are specific in its title and still in the first line of paragraphs will hold a better possibility for the observation and explosion of your website, products, business, blogs or articles.
There are two methods you can use to arrange your keywords in your articles. Using a keyword in each paragraph is one method. Another one is using the keywords twice in the introduction (first paragraph), twice in the conclusion (last paragraph), and once in each of the other paragraphs.
The articles with keywords, which have been optimized for search engines, should lay down important information to attract the readers to have the interest to dig your website, seek a product, or look for a service. Keeping the balance between employing specific keywords and the quality of your contents is very important.
An article with flooded keywords but poor contents will not attract the eye balls to your businesses. The readers will leave away and turn to the other contents available on the internet.
