Fresh content means that you are continuing to add new pages to your website. Not only is it important to keep your current audience engaged and attract new followers, but the more new content you add the more chances you have to improve your ranking for searches and keywords. Search engines crawl and read your site and when they find new content, this tells them that the website is active. Plus, every time you publish new content you get re-indexed, also helping improve your SEO. Lastly, consistently publishing new content increases your overall authority on the subject matter. Other sites are more likely to link to yours and this tells search engines you know what you’re talking about.
