Difference between SEO and SEM

[Grahamson]

SEO is the process of improving a web site's placement in the free listing of the search engines like Google, Yahoo! and Bing . These free listings are also known as “organic” listings.

SEO involves:
1. On-page Optimization - Making changes to the HTML code on the pages of your web site to improve the relevance of certain key words/phrases on each page and fix any problems which may stop the page being indexed by the search engines.

2. Off-page Optimization - Getting back-links from other relevant sites, preferably using key words (or “anchor text”) in the links themselves - e.g., links from directories, through article marketing, or even paid links on relevant sites.

SEM aims to create additional traffic to websites by increasing its visibility on the search engine result pages (SERPs). SEM are those marketing practices that cost money to generate the traffic like Buying placement in search listing or what we called paid inclusion. It also includes Pay-Per-Click advertising like Google Adword and Yahoo Search Marketing. The Difference Between SEO and SEM : Small Business Support Network.
