Article marketing is one of the most effective methods of SEO. However, simple writing does not serve any purpose. The writing needs to be targeted at your audience and the audience looking for you on the search engine. This type of article writing is called SEO article writing.
There are certain rules how the search engines work and your writing needs to satisfy those rules so that your content stands optimized as per search engines. For search optimized article writing one needs to understand the concept of keyword density.
Keywords density means using a keyword for a certain minimum number of times per hundred words in your content. The keyword should be used very naturally and it should not be just pushed into the sentence even where it is making no sense.
The search engines have a limit to which the keywords density in your content is accepted and beyond that, they consider it spamming. The search engine crawlers register only those sites, which fall within their keyword density. Thus, it is necessary to not spam your content with keywords rather use keywords into the content naturally.
You can start with the heading itself. Keep the main keyword in the heading of the article. Try to keep the heading as attractive as possible. Next moving towards the body of the article, mention the main keyword in the first line of the first paragraph of the article.
Write the article in smaller paragraphs so that you can use the man keyword in each paragraph at least once. It is a good idea to use the synonyms of the main keyword in the article. This will keep you from spamming as well as repetition. An article with 2-3% keyword density is considered good for search engine optimization of your site.
Again, do use the main keyword for your article in the last line of the last paragraph. It is essential to use the keyword at the starting and at the ending of the article. It is done to aim at the organic traffic brought by the search engine. Use the natural search phrases as well as sub headings for paragraphs that contain keywords.
This is how SEO article writing is done and can be used to create naturally search optimized content for your site.
