When you use meta tags on your website, avoid using the same keyword over an over again. This will make Google’s Web Crawler think that you’re trying to gain more keyword relevancy, but you can use variations of the keyword. This will not get you more keyword relevancy, this will definitely hurt your search ranking. Also, when you are writing content for your website, do not overuse the keywords, and do not keep them close together. Just let your keywords flow naturally as you are writing.
