One thread that you will see in every SEO guide is that content is king and to rate well in the SERP’s you need to provide fresh content on a regular basis. Since search engines only index pages, does it matter how many pages you have and how often you add new content?
It is an interesting question and search engine do only index pages. That doesn’t mean they don’t look at the overall site. More content, from a search engine optimization point of view, does help. From the search engines perspective, the amount of content is not nearly as important as the content itself and the other factors such as inbound links.
To a certain extent, that is where the issue sits. The more good quality content you have, the more you will be seen as an authority website on particular topics that are relevant to your content. With authority comes respect and the willingness for other site owners to use you as a reference using quotes and links. More authority equals more links. That said, adding content on a regular basis is a big help – if it is good quality.
Blogs are a little different. Blogs rely on a regular supply of content to keep their regular readers coming back. Regular readers who find the content valuable will link back to content when it is appropriate.
Adding regular content can also help with the internal links structure of a web site. This can help to boost the home pages rankings within a search engine. While increasing Google PageRank is not an important issue as it once was, you will often see a home page with a PR of 2 or 3 yet most of the internal pages are only sitting on a zero or one. Using internal links, where every page links back to the home page, helps to improve the home pages rankings.
The final major reason for adding content on a regular basis is that it encourages the search engines to visit and index your pages on a regular basis. The more often the search engines visit and spider your content, the more your pages will be indexed. Does more content help with search engine optimization – indirectly, more content can help a lot.
