Your ability to write optimized copy that supports your business goals will depend on how well you can balance the requirements of two very different audiences: humans and robots (Google and other search engines).
Most people will not read the article if the title is drab or boring… search engines give high relevance to the first few words used in the title… If you use the same title as the others, your article will be lost…The optimum keyword ratio is 2-4% of total words in the article. The more keywords you include in the article, the higher it will show up in the search engine results. However, “too much of anything is good for nothing” and so, if you use your keywords too much, than your article will be viewed as spam… Anything more than that will make the article difficult to read and will also destroy the professionalism of the article.…you will come to know which keyword is commonly used. Make sure that you select the keywords that are specific rather than common.
