First off, thought I'd point out to you that your Online-Webcams theme is a bit messed in OPERA, 1280x1024 res.
Next, I have to say you have some nice themes, the sites look good
One reccomendation I'd have for your 'dating' blog, is maybe some more pics... there is a shitload of text, which is good for search engines, but its not that likely that a user will get all that excited when there are only 3 pics on the page and 10,000 lines of text :P
Keep in mind, you can have the ugliest site in the world, but if you have traffic you can still convert like crazy. Traffic is the hard part in the internet marketing biz.
You have some options for traffic:
Blog Directories - You will get a few hundred visits a day for maybe a week as soon as your blog gets accepted, and then the visits will taper off. Bad news is that you now have traffic leaks going out to blog directories that most likely will not send you all that many visitors ever again.
Link Dumps - Don't count on much traffic from these, but it doesn't hurt to dump some posts and your main blog url... at least increase the chances of spiders coming to your site and indexing it.
Link Trades - Take some effort and trade with others and their blogs... you will increase chances of spider visits, some site exposure, some (possibly really good) traffic, and maybe even make some adult webmaster friends
Search Engines - Like someone else mentioned in this thread, you want them to find you via links from other sites. To do this you can utilize Link Trades as well as Link Dumping, and maybe even forum sigs. Don't bother 'submitting' to engines, unless maybe its the smaller less known ones. Google, Yahoo, and MSN should index your site in time without any submissions required.
Now, Search Engine traffic is gold, its usually targetted well (if you targetted the right search terms), and it WILL convert quite well. The problem is that you often have to wait 6 months after initial indexing to actually gain some favour with Google and start recieving good regular traffic. But for the first few months your site's relationship with Google will probably be...
So my friend, I shall leave you with one last piece of advice... BUILD YOUR NETWORK. Build site after site, let the existing ones age, updating each once every few days... and continue making more and more.
6 months later if you followed this advice, you should have a fairly large network of sites, at least half of them aged well and recieving steady traffic in Google... which means $$$
Stick with it bro,
