Hey guys, One thing that I've been wondering about lately (now that I've started to rebuild a site that was hit by Penguin last year), is how we build links to our tier 1 properties. At the moment, web 2.0's seem to be a popular choice to build contextual links back to our money sites. But from there, it seems like "high pr" links to those properties can be junky (but juicy) blog comments, forum profiles, spun articles etc... yet still get their share of link juice without any penalty. Penalties that our money sites would suffer if we sent those kinds of links at them. Since I started building my new website, I am being extra cautious for the moment until Penguin atleast starts running "real time" as they put it. that's why I'm building tier 2 contextuals to my tier 1 contextuals... I think that this will probably take much longer than usual to rank. From there, I am hammering my tier 2 (which is contextual) with high pr links. I usually just outsource them because I don't have GSA and still learning how to use Scrapebox... but my point is, it would make sense for Google to go after them because they really are quite effective for the time being. Is it worth all the trouble? I don't know. I know it's possible to go bananas on your tier 1 web 2.0s, but how long will that last? It seems to be one of the latest techniques SEO's are getting into, and we all know Google jizzes themselves every time some new algo comes out that makes life a little more difficult for us. Anyway, it would be interesting to hear some opinions on this whether you agree or disagree.
