Fresh Content: Myth or Magic?
Source : Blogstorm.co.uk
The phrase “search engines love fresh content” is used hundreds of times every week by people answering beginners questions on SEO forums. Can you really get higher rankings just by adding new content to your static site?
I’ve always hated the phrase “fresh content” because it adds to the misinformation that people who claim to be “SEO’s” use when trying to educate other webmasters about SEO. Visit the popular forums and the four main pieces of advice handed out are “content is king”, “submit your site to directories”, “exchange links with relevant sites” and “add fresh content”. Thanks to this advice the web is full of sites that syndicate duplicate content from article directories just for the sake of publishing something “fresh”.
Ironically this low quality content is probably doing more harm than good.
Crawl Rate
Websites with content that changes frequently (such as news sites & blogs) often see increased spider activity as Google tries to make sure all the latest stories are indexed quickly. One of the factors Google uses to determine the best rate to crawl a website is the frequency the content on the site is changed. As a general rule if you alter the content on your site more often you should see Googlebot visiting on a more regular basis.
In a patent dating back to 2003 (granted in December 2007) Google entitled Anchor tag indexing in a web crawler system (analysis) Google explains how they could place urls in a series of crawl layers to determine how often the page needed to be crawled. For example news.bbc.co.uk would be in the “real time” crawl layer to be crawled almost continually whereas an average blog homepage might be in the “daily” crawl layer to be visited once per day.
The crawl layers could be altered daily by computing a score based on the documents PageRank and frequency of change. Pages with an abnormally high or low daily score might then be moved up or down a crawl layer.
daily score=[page rank].sup.2*URL change frequency
