Google put a lot of emphasis on the off-page optimization and consider it one of the major factors in website ranking.We DO build the following types of links. We don't do any type of spamming work like submitting daily 50 to 60 links on social bookmarking and directory websites. For new built website or fully optimized websites , we take following things in consideration while doing Seo work. First we ask clients to show us website for which they need work, we just check website keyword ranking on google.com and keyword tool, and then ask clients to provide us accurate title , description and keywords to be used by us. daily we do 5 social bookmarking, 10 directory submission 4to 5 free classified posting, participating in some blog commenting, submitting article given by clients in press release and also maintains profiles on twitter, facebook and google+ and adding people related to client website niche. Please Pm me if any one need these work to be implemented on their websites. thanks
