Think of it this way: The more specific your content, the more specific the needs of your audience are -- and the more likely you'll convert this traffic into leads. This is how Google finds value in the websites it crawls; the pages that dig into the interworkings of a general topic are seen as the best answer to a person's query, and will rank higher.
Article marketing — this method seeks to gain a higher ranking in search engine results by establishing the marketer as a credible source that won't use spam software. Many marketers use websites like Ezine Articles to publish articles that contain a unique "resource box," and as other bloggers and website managers republish the article (with the resource box intact), the marketer who published the original article gradually earns higher search engine rankings.
Consider selling in lots. A lot is a collection of similar items that is sold in a group. For example, if you have a collection of books, magazines or similar pieces of jewelry, consider selling them all at once in a lot. You many not make as much money as you would have if you sold each item separately. However, the items will likely sell more quickly in a lot than they would individually.
