One could say that SEO is a subset of SEM. I look at all projects on an SEM level now, no longer laser-targeted JUST on the SEO aspects, because SEO will only take you so far. SEM involves conversions, ad placement, tracking/testing, etc... SEO is just getting the traffic, but SEM is getting it and converting that traffic into a sale/lead/conversion, which is the most important part.
term seo or seo expert became more popular, most of them actually do all types of marketing that is SEM.
Thanks for the informations. Presently my site traffic has increased as a result number of registration too increased to some extent. However I am confused to understand that whether this increment happened due to SEO or due to some other reason.
These are two different techniques. SEO is a Search Engine optimizer and SEM is Search engine marketer. - The SEO only use optimizing techniques to rank you with desired keywords that appear on natural search. This is normally a one time investment, where as - A SEM mainly managing PPC (Pay per click) campaigns. Using the service of a professional SEM can help you to get more value of money invested in PPC campaigns.
I have checked the STAT value but, search engine referral results are showing more or less same as it was initially, but huge amount of no referrals value is showing. What does it mean exactly.
