How can I optimize the sites from my hosting and so to facilitate the work of the search engines? I think I made all the important things on the SEO optimization, but this seems not enough for the search engines.

If you have free time can register your site in ODP. Due to the high significance of the ODP (Open Directory Project), known as DMOZ, the inclusion of your site in this directory lists is considered a very good achievement. ODP not only provide to Google its lists, but also into directories such as AOL, Lycos, AltaVista, Netscape, Teoma, AskJeeves, Hotbot and many other smaller specialized directories.
