I know some people used this technique : 1) create a software 2) create a pad file 3) submit the pad file to hudreds software directory using submission program Tomorrow morning when you wake up,your site already list in most search engine! Ok, nothing wrong is it? But remember,this technique have drawback.If somehow you want to change your website from video converter to graphic editor,it is not an easy task.Your domain already listed in search engine as providing video converter,even you already changed your content to graphic editor.Your domain is poisons by 'video converter' word.You maybe end up to create another domain
