Hi, I am working on online tutorial site.And I read in an article that it is good for online tutorial site to submit their site into Tutorial database sites.Is it right?
yes as long as you get a good link back to your site. Only thing to remember is that you want your site to have best and loads of tutorials so maybe giving them away isn't a great idea? Don't forget about Google penalizing duplicate content. So you would have to rewrite a tutorial that you have given to another site, if you want to use on your site.
