Which is the best SEO or SEM?
Thanks in Advance.

According to me both are the best strategy of internet marketing. SEO is the element of SEM. SEO is the process of improving the visibility of the website in search engine via natural or organic search results whereas SEM is the act of marketing a website through the use of paid inclusion and contextual advertising. SEM includes SEO.

In simple words, SEO is free and SEM is paid. SEM includes both SEO and PPC.

i think about that SEM - Search Engine Marketing is all that can be done to use the technology of search engines with the objective of promotion website and increasing its traffic and business.

search engine optimization is the best for me as it doesn't require money to start you can do seo of your blog as well, you can use Adsense for earning money and you can earn great money.....

If you are good at SEO then you wont need SEM. SEO is easy if you follow some simple guidelines. I can send you my cheat sheet if you give me your email (all free of course)

SEO (Search engine optimization) is a part of SEM (Search Engine Marketing). SEM is part of internet marketing. Both are use for increase website visibility on major search engine like google, yahoo, bing etc. SEO increase free online traffic and SEM is use for increase free and paid both traffic.

SEO and SEM both are techniques of internet marketing that are done to get keyword rank at good position in search engines. Seo use several technique thatt focus on creation of backlink and through then it gets traffic. SEM is usually paid and includes techniques like ppc.

SEO and SEM they both are good to increase traffic as well as brand awareness. SEM is mainly uses to increase your brand value and brand awareness. SEO is part on link generation.

Well,according to me both are equally important.
SEO stands for Search Engine Optimization and SEM stands for Search Engine Marketing.

SEO is a search engine optimization that help to increase website traffic, backlink and pagerank, it is free method where as SEM is a search engine marketing that also help to increase pagerank, traffic and backlink of website but it is paid method that include PPC method.

When SEO and SEM teams are operating independently, there are often high-volume keyword terms that drive traffic from only one of the two search channels, either paid search or natural search. When you find these terms, you can better optimize them.

If you are good at SEO then you wont need SEM. SEO is easy if you follow some simple guidelines. I can send you my cheat sheet if you give me your email (all free of course)
