My Amazon Affiliate Website Examples....On the right track?

I have

bestrazorforwomen.com

spottingscoperatings.com

besttelescopebuyingguide.com

All built on Thesis with only a contact plugin installed

bestrazorforwomen.com is #1 on Google making about $10/month with just under 1000 unique hits per month. It only took a couple weeks to reach #1 and made money in month 2 now for a few months. Bad Conversion but people are clicking through to Amazon.

spottingscoperatings.com (new) with only one article but wanted more experienced Amazon affiliate members to offer opinions about layout, keyword(domain), etc so I can duplicate.

besttelescopebuyingguide.com has several articles and information however just a few weeks old in a more competitive niche. Good keyword choice?

I know you have to live and learn but still trying to figure out the best way to hit on the best keywords for domains in any given niche.

bestrazorforwomen.com got about 700 (local) searches on Google keywords/adwords so I went with it in order to develop/learn what I was doing and then figured I could duplicate that success. Granted better items with higher prices would make more money but I knew going in the price points were low.

So, finding keywords for my domains seem to be my biggest hurdle still but I think I have a grasp with on page SEO. I hate off page SEO but striving to do it better just don't have a clear cut direction with off page SEO. Any suggestions on a plan-I know social bookmarking, forum and blog postings are needed but my problem is not having a plan.

I thought maybe if these were a good direction then newbies could duplicate. I know for myself I would have loved to see working examples without buying WSO's right from the start.

So, any experienced affiliates have opinions, criticisms or advice it would be GREATLY appreciated as to if I'm on the right track with my first 3 Amazon affiliate sites.

Update:the sites are live. Seemed like server had a hiccup for a minute.
