Search Engine Optimization (SEO) - An Overview

Search Engine Optimization (SEO) entails a maelstrom of techniques and tactics with the end goal being to improve the ranking of a particular website in the search results of major search engines. SEO can be broken down into two main categories, on site SEO and off site SEO.

On site SEO relies upon excellent content first and foremost. Content must be on topic, relevant, and contain a 5% - 8% keyword (words or phrases) density. This means that for every 100 words of content, five to eight keywords should be used. The keywords that will be used must be carefully researched using tools such as the free Google AdWords keyword tool. When choosing keywords, it is important to remember to think like the customer. What will they be searching for? These same keywords should also be embedded into the website source code via Meta, Title and Heading tags. This will help ensure a high page ranking for these search terms.

Also, the website should be organized with a clear hierarchical structure. Creating a site map will significantly enhance site structure and ability to be scanned by search engines. This will allow search engines to more efficiently scan the target website. The most important information on a given website should be placed at or near the top of the page. This will make it easier for search engines to find the content that you want them to find. Use text instead of images; search engines can only scan text, so all important information must be included in text. This should be done even if the message(s) being conveyed are duplicated in images, banners, etc.

Of even greater importance is off site SEO. This includes back linking to highly ranked sites. For example, you can submit articles to free online repositories with links to your target website embedded in the text. The Google search engine will interpret a page with many back links to highly ranked pages as being of greater importance, and will therefore increase its page ranking. Another tactic is to submit entries to a highly ranked online blog, with excellent content, important keywords and back links where possible. Furthermore, you can join appropriate, and highly ranked, online forums and post useful content with a signature containing a back link to the target website. You should submit your website to the major search engines' web indices. This will speed up and enhance the optimization process greatly.

SEO is a multifaceted endeavor, and requires ongoing maintenance and tuning. There are many competent companies that are dedicated to carrying out SEO campaigns. If page ranking is extremely important to you, consider outsourcing the project to a professional SEO company.
