SEO is all about working on onsite and offsite factors. While onsite factors include navigation, title, structure, copy, and other coding tags and tweaks, offsite factors are all about linking to the right sites, article and directory submissions, and press releases. Organic search engine optimization is the main source of traffic for websites these days. On the other hand, PPC is way of sites to appear in important positions on major search engines by paying the engines. 

Another major difference between the two is that while PPC is a paid form of advertising, organic search engine optimization is absolutely free. But, climbing high on the ladder of SEO requires a lot of hard work and patience. SEO stands for Search Engine Optimization. Search Engine Optimization is the process of improving the visibility of a website or a web page via the natural, organic or un-paid search results. SEM stands for search engine marketing, this is a paid method of online marketing. 

Think of your website as being a cake. Nobody knows it's there until you start spreading little tastes of it around. Once you have a constant and increasing stream of visitors and your name becomes known, should you stick your financial neck out and use PPC or Facebook marketing. When marketers are talking about Web 2.0 they are also talking about the tendencies of users to be in a line interaction activity with them. Gone are the days of one way marketing or merely just posting comments about your site or other related topics. 

Acquiring a huge volume of site traffic is the lifeblood of a SEO campaign. Once you were able to get more traffic, people would recognize you as a trusted source for related information, thus earning a higher ranking and overthrowing other competitors. If you want to achieve the best search engine optimization results for your online business, doing SEO yourself may not be the easy way to do it unless you are an expert yourself and know exactly what has to be done. It is not an easy task, and a little knowledge may not be the best for your online business. 

The importance of both the techniques can hardly be over-emphasized as both are important to keep pace with the ever-changing web world. Both are important for advertising products and services to your customers and for attracting traffic to a site.
