You should look on your business web site as a new resume or think of the web as a giant digital newspaper. If people have no idea who you are or what you do after visiting your site, your business will suffer.
In the past, search engines looked primarily at meta tags. When people began "spamming" search engines, or repetitiously placing keywords in meta tags and page text so they could pull poor sites ahead of good ones in search ratings, the search engines changed their formulas (and continue to do so) to push spamming sites down and bring worthier sites up. If, however, you are truthful with both the spiders and your customers, you can achieve decent rankings.
What is a CMS? A CMS or Content Management System is a system that enables anyone to manage a website without having to learn the technology that drives the website. Creating, editing and publishing content becomes faster and easier.
There are a few owners of websites who feel that it is ok to simply have an online presence. But if you've paid for the construction and hosting of a site, why not finish the project and market it properly? With a little effort, the results and returns can be astounding.
If you've had your website for a while, then perhaps after the initial rush of enthusiasm, you haven't updated it as often as you would have liked, and it might have not have been given the attention it deserves, and now it looks stale and not as fresh as it used to.
