The difference between SEO and SEM is simply that Search Engine Optimization is part of Search engine marketing or Search marketing as it is widely known. Both processes aim in increasing visibility in search engines. SEO is about optimizing the web property to get better rankings in the search results while SEM goes beyond SEO.

I agree with you that Seo is the part of SEM. The only difference I found between them is that work of SEO is limited and focused on just to increase the visibility of a website in search engine with the help of the predetermined methods while SEM works on with the every change in the position of a website so that it will have the maximum benefit.

SEO basically stands for Search Engine Optimization. SEO is process of getting traffic from the free and natural listings on search engines. SEO is a technique to increase the visibility of your site in search engine.

SMO stands for Social Media Optimization. SMO tactics can drive huge amounts of people to a website and can also determine whether a startup, website or idea will make it or not. It involves driving traffic to a website through new channels because search engines aren't the only sites that drive big traffic anymore. Websites such as Digg, Delicious, Facebook these are all websites that can now be used as places to put out your marketing message.

SEO is the process of optimizing your web site for the purpose of getting free traffic from search engines. An optimized web site is more easily understood by Search engine crawlers, so there are more chances of ranking higher in SERPS. SEM is the marketing process with a goal of getting more visibility in search engines either by getting more free traffic (SEO) or paid traffic.
