Internet marketing is now one of the most popular and cost-effective forms of marketing. One of the main reasons for this is businesses can target very specific markets and can calculate a relatively accurate Return On Investment (ROI) . The most common forms are Search Engine Optimisation (SEO), Pay Per Click marketing, Affiliate Marketing, Banner Advertisements, and E-mail Marketing.
Search Engine Marketing (SEM) being the most popular seeks to advance websites by increasing visibility in Search Engine results pages. There are three different techniques connected with Search Engine Marketing: Sponsored Links, Organic Search, and Paid Inclusion.
Sponsored Links are purchased through Pay-Per-Click or Pay-Per-Call campaigns (also known as PPC). Simply put, businesses bid on keywords that are relevant to their services or products. Then, according to how high their bid is, their ad appears in the sponsored link areas when a user engages the search terms. Sponsored links are usually located on the right side of popular search engines like Google, or Yahoo.

Organic Search: The main body of search engines is made up of organic or “natural” search results. These listings are generated based on relevancy factors according to the content found in a website and to the number/type of links pointing AT a website. By specifically tailoring these elements, a company can focus on particular audiences in a similar fashion as PPC. Organic search results are much more difficult to get your site listed in and often require the hiring of a SEO expert
Banner Advertisement is the method of placing an advertisement on a web page with the intention of driving traffic to your site. New technologies have given the advertiser amazing customization capabilities when it comes to banner advertising. Advertisers now have the ability to place their banner ads on very specific pages devoted to certain types of content and products. So if you are selling teddy bears, you can have your ad appear on a site only when it is presenting an article on the teddy bear industry. You can also zero in on geographical targets (or “geo-targeting”). By tracking the IP address of the user, you can have ads appear only to those people in your target area. Targeting has breathed new life into the traditional banner advertising industry.
