SEM – A Combination of SEO and CPC?

Most people think that SEM is a paid search service and it does not include SEO in it. Search Engine Marketing or SEM is something more like marketing a particular website with the help of search engines which people commonly use to find content on the internet. It can be utilized to increase the rank of a website in organic listings or paid listings or a combination of both. SEM can be referred to search engine marketing and also it can be referred to a website or a person who does this type of work.

Some people think that SEO is very much different from SEM and claim that they do both SEM and SEO. But the fact is that SEO is a part of SEM and if a person is doing SEM as his job then he is automatically doing SEO because SEM is a combination of SEO and CPC.
