I am a newcomer to this world of search engine optimization (SEO) and was seeking for some assistance from you experts. I would like to study about SEO online. Until now I have learned regarding various SEO services such as article submission squid, article writing etc. I have also been capable to use these services to get great effect. I am now seeking at the preferences of social bookmarking as well as social networking. What is the distinction between these two? Can anyone please enlighten me on this? I would appreciate your comments as well as take them into account at the time of site optimization.
