Pumper Sites - How to optimize them

Hi, I have a plumbing company in LA. My main site is about 4 years old, PR2. Ranked 3 thru 14 for five main KWs. About 6 months ago I created 10 other sites optimized for people seaching for plumbers in other parts of so-cal. i.e. santamonicaplumbing dot com, hollywoodpplumbing dot com. and so on.

They're all 5 page sites, ranked on 1st or second page (after buying a few packages from Service section of BHW, and submitting to lots of local directories.) After reading the forums about web 2.0s properties quite a bit, I guess it occurred to me it would be a better idea for me to treat these 10 sites like 2.0 links. Avoid 2.0s to my main LA plumbing site. Pump all the links instead into these 10 sites. Safer probably. If this is dumb, let me know.

If not, please tell me if this plan is adequate: For each of the 10 sites: 1. post weekly articles 2. build 5-10 2.0s for each pumper site. No more, ever. just work on sending links to these 2.0s. 3. Better quality but low quantity high Pr blog comments, article submissions, profiles, bookmarks, wilkis for 2.0 props.

My question are: 1. what is the optimal way to link to money site on each of my pumpers? Do I mix it into the content on the homepage, and vary my keyword location (throughout the text) on each of 10 sites? Do I use my 2 main keywords 5 times, i.e. la plumbers, plumbers los angeles? Or should I use some generics.

2. when I add content weekly to my WP blog, what percentage of these posts do I link to my money site? Should the link to money site be accompanied by a link to authority? Should both links be together? I'm just confused on how I should handle linking throughout blog. Thanks so much for help.

Are all of the domains on separate servers? Or are they all on your one account?

seperate

If they're on separate servers, make sure you get private registration and that the nameservers are distinct (or that the hosting company uses the same NS for all clients).

Set up different themes and different settings. Build different links to each domain and link to different sites. Set a posting schedule and post different days/times. Basically avoid all patterns. Hopefully this will be enough to protect your network and give you strength to your domain.

What I would do is try to rank each domain for a separate but related keyword.

For example, your main keyword is 'widgets'.

Domain 1 - 'red widgets'
Domain 2 - 'used widgets'
Domain 3 - 'buy widgets'
Domain 4 - 'What are widgets?'

Then as you link to your main site and non-competing, but related sites, you'll give your main site strong links, but also, each site will pull it's own weight as Eli suggests.

thank you,

should i continue to link to my money site in other blog posts, or just on the front page?

I would keep it natural looking. 3-5 posts on the front page, link to your site every 2-3 posts. Something like that. You want these to be real sites with real content that can rank for their keywords.
