Yes that right. SEO is like a magnet that draw in your customer like a magnet.
Once a website has been ranked in Google. It can draw visitors to it very cheaply. In my experience a well optimized website can bring in many visitors long after the website style has been made obsolete. That is why sometime the best performing site from a SEO perspective are the ugliest sites.
But let get back to the magnet, a magnet draw metal towards it. But in this case you want customers right?

But without a way to get eyeballs on the site. Well just like the tree falling in the wood no one will care about your website.
So how do you get customers to your website. You could pay to advertise it. You could tell people. You could even get on a building with a microphone and yell from the rooftop for people to visit your website. But are any of those tactics going to work.

Just by writing you content in a search engine pleasing why with the proper title and hidden little code on the website. With a few well placed link. Then presto SEO is now drawing customers to your site like a magnet.
