What is Search Engine Optimisation (SEO)?

Search engine optimization, or SEO, aims to index and improve rankings for the webpages which are most relevant to the keywords searched for according to the algorithm of each search engine. The relevant pages are returned in search engine results pages (SERPS).

Optimisation of web pages 

It is important to remember that genuine search engine optimizers are basically marketers who keep their target market in mind as much as the search engine algorithms (a lot of which is known purely empirically). Therefore, while we call this process search engine optimization, good marketers will note that their focus is to optimize their web page for the search engine user, who is their target audience. For instance, at one time it was believed that keyword density was an important ranking factor, but today that view is not generally held among SEO professionals. Today, many SEOs recommend writing copy for visitors first, because the web site cannot achieve its marketing objectives with "unnatural" sounding text, laden with keywords.

Optimisation of web site architecture

In order to further fine tune the pages and keep them user and search engine friendly, the architecture of the website, including its internal link structure, navigation etc., are also suitably modified for human beings and search spiders to navigate through whole website pages. Search spiders then can scan all necessary data about the whole site and store it in the search engines' data base. A good navigation systems has other benefits also, such as helping to improve user experience.

Why are back links so important?

Both the number of inbound links to the site as well as the 'quality' of the links heavily influence the rankings of a site in the search engine. The definition of a 'quality' link is evolving in response to people's attempt to artificially influence the search engine results by obtaining large numbers of 'irrelevant' links to their sites. Search engine algorithms are evolutionary and strive to develop every day in an attempt to provide the most relevant and useful pages to the users and strike out the websites that trick them to attain higher positions for a while.

Organic SEO versus PPC

These processes are known as Organic or Algorithmic Search Engine Optimization (SEO) of websites. Search engine optimization takes considerable time and, as such, many sites make use of Pay-per-Click (PPC) to market their website without having to wait for the results of Organic SEO. However, organic search results can get viewed and clicked on frequently, so a dual strategy of SEO and PPC can provide more exposure than either strategy alone.
