Modern algorithms are designed to analyze and favor quality content. There are a few ways that you can use this to your advantage. First, always provide unique and relevant text, which should be a given. Second, make sure that key words are used in title and header tags within the content. Use a keyword density tool to ensure that you are at the perfect keyword density, which is less than 4%.
Long string keywords are important to include in high quality content. Many people search for these keywords, such as “how to brush fluffy siamese cat after bath” and similar. Because most highly ranked sites are not optimizing as much to these long string keywords, even the smallest and lowest ranked website has a chance to get on the first page of results with these.
