I would like to discuss about links type, because I don't do off-page manually. I would like to share my exp on buying links on BHW. Feel free to comment or correct my points. 1. blog network. frm my experience of purchasing this kind of links in BHW, I realised that this is the most effective links. but they're not reliable, few blog network slapped by Google. 2. high pr blog post aka guest post. the second most powerful links, but if a post contains too many outbound links then no point paying for crappy link, no juice will passed. 3. web 2.0 - this can be really cheap. Don't expect much on this. web 2.0 alone won't boost SERP frm my exp so far. 4. comments - good for links diversity. I don't spend on this, no good results so far.
