If you want to have an online store, then there are some things that you need to keep in mind. The difference between selling on eBay and having an online store is that if you have your own store, then you will have to look for visitors yourself. Ebay has millions of people visiting the site, so you will not have to worry about traffic, but if you have your own store, then you may need to advertise. However, there are some advantages of having your own store as you will not need to pay listing fees like it is in the case of auction sites.
There are many site rankings out there and this includes rankings such as Alexa rank, Google Page Rank, and others. Some webmasters are very determined to raise their rankings any way possible. It can be nice to be ranked well, but ultimately your site is worth as much to someone as much as he visits your site. You can have a site that is not ranked very well, but if your visitors enjoy visiting it, then there is nothing wrong with it. Also, each rank may rank your site in a completely different way. According to one rank your site may be ranked very well, while another rank will rank your site pretty badly. What I am saying is that most ranks are not very reliable.
