Hi all,

what is the difference between SEO and SEM ? is SEO a part of SEM ? any body please provide me the information regarding this..

thanks in advance..

SEO is Search Engine Optimization in which we optimize our website for search engines.SEM is all about paid links, advertising more likely on building links.I think that a SEM campaign includes SEO, paid inclusion, pay-per-click, and other related services that will increase qualified traffic to your web site.
