I'm going to be meeting with a possible client this week and they need SEO done for their site. For my own sites the SEO I typically do are article marketing, blog commenting, web2.0 sites, social bookmarking and achieve good results. Now for a client which linking methods would be wise to use beside article marketing? Would it be OK to build Web2.0 sites on wordpress, blogger, etc. and have articles there that link back to clients site? What about High PR blog commenting? Any problems with doing a bit of social bookmarking? Which would be considered your typical white seo and not fall into black hat area too much?
