Why Is SEO BIG?

SEO is a big business. What do you think are the reasons behind its immense stature on the World Wide Web?
SEO is BIG because:
1. Shoppers spend more time online.
2. Shoppers spend less time reading dailies, watching television, and listening to radio.
3. When searching for something hot, shoppers bank on search engines for help.
These are the reasons why in the minds of business proprietors and marketing professionals, SEO is a must. And they are also the reasons that push marketers to put strong emphasis on web search engines.
There is a rife assumption that having a presence at the top of the search engine results is the only – or at least the most efficient technique of using the internet to attract new shoppers. This is understandable if the demographic is not that acquainted with SEO.
On the other hand, internet users only spend a little time on search engines. This is why savvy marketers combine SEO with other forms of marketing to produce efficient results.
