What is difference between SEO and SEM?

[ashwinimaster]

The terms "search engine optimization" (SEO) and "search engine marketing" (SEM) interchangeably. Though they are both marketing techniques, they do have definite differences. SEO is the process of improving a web site's rankings in search results of search engines like Google, Yahoo, and Bing. These listings are also known as "organic" listings. SEM involves driving website traffic via paid advertising, such as PPC (Pay-Per-Click) ads. SEO helps improve organic search results while SEM focuses more on advertising.

Hi.... friends.!!

Actually SEM is the mixture of PayPerClick and search engine optimization strategies, rendering it appropriate for the internet marketers to obtain instant outcomes.

In other word, SEO is the process of improving the SERP of a website  in major search engines like Google, Yahoo, and Bing. These listings are also known as "organic" listings. But SEM involves driving website traffic via paid advertising, such as PPC (Pay-Per-Click) ads. SEO focuses on improving organic  search result while  SEM focuses on advertising.
