This is excellent advice. You can of course also submit your site directly to Google using their submission tool. I always do this first and then follow the other procedures as already stated. A direct submission seems to speed up the process - it has for me anyway - and I have often found a site active within a few days. Regards
Fore indexing your site faster you have to provide unique content because google love uniqueness. make some quality Backlink on hige PR site.
