SEO is important because this is one of the very important ways to get visitors to your site.
No Visitors = No Revenue.
That sums up a lot but still SEO is important for various other reasons.
1. It brings visitors, and so when for some reason your site has lost rankings,
2. It brings repeat visitors.
3. Since you have achieved top ranks, there will be many sites, blogs and directories that will link to your site. Many will do it for link exchange purpose – but anyway you get a link.
4. When you get links, visitors from other website come to your site. And if they are website owners you get more links.
5. SEO gives you an opportunity to learn. You learn what exactly to do to remain on top and in business.
6. SEO well done is ego satisfied too. Imagine working hard on a project for six months, and then seeing the site ranked well for the keywords you were targeting.
7. SEO gives you an opportunity to expand your business. More visitors, means more money to invest in the business or try new business. However please understand that sometimes more visitors does not necessarily mean more money.
8. SEO forces you to study your competition sitting right in your home/office. Agreed you can do it just like that, but if you are trying SEO, this is one of the major works you need to do. Sometimes we are forced to do certain things and it is good for us. Isn’t it?
9. Well done SEO may even help you to leave your full time boring job and start your own business. Did I forget to mention it brings more money than your salary?
10. And now this. SEO/SEM professionals get high salaries too.
