A common thread among both humans and search engines is to check the POST date on website blogs, news, and comments.
Humans often relate the freshness of content to the organizations’ own understanding of current trends. This connection between a website and its owners does not have to be true, it is just perceived.
Also, SEO (search engine optimization) experts believe continual fresh content is one of the most important ways to have higher rankings on search engines, but only if the content is relevant to the rest of the website (Rankpay.com, 2010). If the most recent posts are not very recent, the entire site could be understood by search engines to be not as important as a competitors website.
