Best way to promote large number of domains?

If you have large number of sites with some popular keywords in url.. lets say you own
www.FuturamaFirstSeason.com
www.PrisonBreakFirstSeason.com
www.RadioheadNewAlbum.com
www.MetallicaNewAlbum.com
www.BritneySongLyrics.com
...
etc

I guess you are ahead of other sites, but only in theory. It helps, but it's not enough just to have exact popular search phrase in url so some promotion must be done. So, what do you think (or know from your experience) is the best way to promote large number of those sites?

Some usual types of promotion like blog/forum/social sites promotion are too time consuming when you have many sites so what do you think is the best in this case?

 

please delete this other thread, it's a dupe obviously

 

I think promoting all your sites thorough internal linking will be good option. You should have static IP for each site for good SEO.

 

yeah but wouldn't that be too expensive? static IP for each domain?

 

It cost $1 to $2 mo. You can just have it for 1 site.

 

You can add a chatroom into your website ,each room with different topics for members to discuss ,keep them alive in your website .

 

but does that also means you have to buy new hosting account for every new domain, instead of using only one hosting for tens, even hundreds of small sites?

this also sounds hard, even impossible, to control all those sites for spam posts and stuff like that
