Building Blogs For Backlinks

I'm creating blogs specifically for linking to my main sites to build SEO.

1. These blogs are niche related and have niche related named URL's

2. I'm using two different article spinners to post ONE unique article throughout 10-15 blogs. Linking to main site 4-5 times in article.

3. Will posting others articles (like from ezine and such) hurt my blogs since it would be duplicate content..? I'm trying to build the content of these blogs since they are a bit bare and just created.

OR should I just post unique content from my own article spinners?

I know we are all using this method cause it works great.

is this somekind of linkwheel ?
my suggestion is don't use the same anchor link multiple time.
good luck

sort of.. I'm not going to bother linking the blogs together but instead of shoot for low ranked backlinks that are niche related.

I try to only rank for tons of long tails so I don't need tons of high page rank backlinks and such.. just some here and there..

--Good call on the different anchor texts.. I tend to split it up a little bit.

just spin the content you get from other sources....

This is the method which is described in Backlink gold mine 7.0. If you are going to have only 10 -15 blogs, better use unique content. But if you planning for 100 and above, you can use repeated articles.

But remember never use a single anchor text in all articles or blogs.Always use shuffle your anchor text or keywords better results.

When you say you're creating blogs, are you talking about free blogs like Blogger or blogs on domains you own?

If the latter, you shouldn't be hosting them all on the same server if you're linking them together.
