When a topic is typed for search, nearly instantly, the search engine will sift through the millions of pages it has indexed about and present you with ones that match your topic. The searched matches are also ranked, so that the most relevant ones come first.
Remember that a reader will probably only look at the first 2-3 listings in the search results. So it does matter where your website appears in the search engine ranking.
It is the Keywords that play an important role than any expensive online or offline advertising of your website.
It is found by surveys that when readers or customers want to find a website for information or to buy a product or service, they find their site in one of the following ways:
1) Through a search engine.
2) By clicking on a link from another website or page that relates to the topic in which they are interested.
3) Occasionally, they find a site by hearing about it from a friend or reading in an article. (aka mouth-to-mouth or viral advertising)
Thus it’s obvious that the most popular way to find a site, by search engine, represents more than 90% of online users. In other words, only 10% of the people looking for a website will use methods other than search engines.
All search engines employ a ranking algorithm and one of the main rules in a ranking algorithm is to check the location and frequency of keywords on a web page. Don’t forget that algorithms also give weightage to link population (number of web pages linking to your site). When search engine optimization is performed by a qualified, experienced SEO consultant, a site really stands a bigger chance in high search engine rankings. Unless you have a lot of money and can afford to pay the expert, with better knowledge of search engines and how they work, you can also do it on your own.
Understanding the importance of search engines and how they work, will eventually give you enough insights for you to start thinking about the importance of search engine optimization (aka SEO).
