1. I have found a local blog network, like blogger - blogspot but a much smaller users base, where you can create your own blog. The network homepage URL got a pagerank of 4, the homepage lists all the blogs registered on the homepage with anchor text and URL and there aren't that many blogs as the network is meant for quality blogs. How much seo power will this linkage pass to the website I link to from a blog? 2. I have also found dropped domains that have thousands of backlinks, according to Majesticseo, but display nothing in google using the queries site: and link:. Is it worth registering such domains? What about the 0 results in google, are they banned or will they be picked up by google once registered again? 3. Are there any potential risks with interlinking between adsense websites or websites you own at all? I just stumbled upon a couple of adsense sites interlinked that are owned by the same person.
