There has long been debate over whether or not blogging helps with SEO. While some believe that it can definitely help, others disagree. Ultimately, it depends on the blog and the specific techniques that are used. If a blog focuses on creating high-quality content and using keyword rich titles and descriptions, then blogging may be helpful with SEO.
However, if a blog is primarily designed to drive traffic to a website, then blogging may not have as much of an impact. Ultimately, it is important to focus on creating high-quality content in order to improve SEO.
