Why must SEO be done on a regular basis?

SEO is not a once-and-done-forever strategy. It takes dedication, time and research. Search engines such as Google are constantly changing their ranking algorithm. This means that what was working best last month, could be a lower ranking factor the next. It is important to include SEO into all your content. To keep up with the ever-changing algorithm, you need to research it frequently and watch your competition closely.
