Sites with more content can have more opportunities to rank well in Google. It makes sense that having more pages of good content represent more chances to rank in search engine result pages (
SERPs). Some SEOs however, do not focus on the user’s needs, but instead create pages solely for search engines. This approach is based on the false assumption that increasing the volume of web pages with random, irrelevant content is a good long-term strategy for a site. These techniques are usually accomplished by abusing qlweb style catalogues or by scraping content from sources known for good, valid content, like Wikipedia or the Open Directory Project.
