You may have learned that Google needs Search Engine Optimization or "SEO" to find your website. You can read about a wonderful website that has gone "missing" here or a comparison of the results of two websites, one with SEO and one without it. If you realize that making a great website in the internet economy is a decent start but not enough, how are you going to find that great website? SEO facilities are many to sell. How to choose the one that suits your business?
Some developers or hosts of websites will pledge to "do SEO" for your site but SEO is not a one-time thing. Yeah, there are elements that a developer can make of website creation that will make the website search engine friendly. And your host website (where the website resides), along with the 50,000 other websites they host, will do stuff to promote your site. Usually this is an entry in a database of directories they maintain and that nobody uses. These are a tiny part of the SEO process.
