The methodology of performing the social media activities to make your website visible in the social media (facebook,twitter,you tube etc.),with an intend of attracting unique and quality visitors to your website.
One can do it by following ways--->
1.increase your linkability :-Updating the site regularly.Adding a blog is a great step.
2.Make tagging and bookmarking easy:-Adding content features like quick buttons is one way to make the process of tagging pages easier.
3.Reward inbound links :--I don't agree with it completely.The other website might have been linking to you because of the quality of content on your website.So there is no need to reward the inbound links.
4.Help your content travel :--submitting your content to relevant sites will help your content travel further, and ultimately drive links back to your site.
5.Encourage the mash-up :-In a world of co-creation, it pays to be more open about letting others use your content (within reason). YouTube’s idea of providing code to cut and paste so you can embed videos from their site has fueled their growth
6.Get communities connected
Social media activities may include-->
1. social networking
3. video marketing(on YouTube and other free video sites)

Note;--->Social media optimization(SMO) ia all about creating the public profiling of the company so that brand awareness of the company could be increased as well as the net traffic to the companies website.It does not include the paid marketing compaigns on social media networks like making use of facebook ads!while these paid viral marketing compaigns are included in social media marketing(SMM).So SMM includes the paid social search while SMO does not include it.
Note:--->SMM(social media marketing) includes SMO(social media optimization) and placing ads on social media.
Note--->SEM(search engine marketing) includes SEO(search engine optimization) and PPC(pay per click) and PPM(pay per million impressions) etc in search engine page results.So SEO deals with the organic or free traffic to the website through search engines while SEM deals with both organic as well as paid traffic to the website through search engines.
Note--->SEO is the subset of SEM and SMO is the subset of SMM.
Note--->Now a days we usually use these terms interchangeably,though in exact meaning they are different!
