The most of the web traffic is driven by the few major search engines - Yahoo, MSN, Google & AskJeeves (AOL gets almost 10% of searches, but their engine is based on Google's results). If your website can't be found by major search engines or your written content can not be put into their databases, you are missing out on the incredible opportunities that are available to the websites thru search - people who are looking for what you have on your site. Your website may have content, services, products, or info and the search engines are the most important tool of navigation for almost all Internet users.
Search queries, the words that users type into the search box which contain terms and phrases best suited to your site, carry extraordinary value. Experience has shown that search engine traffic can make (or break) an organization's success. Targeted visitors to a website can provide publicity, revenue, and exposure like no other. Investing in SEO, whether through time or finances, can have an exceptional rate of return.
Why can't the search engines figure out my site without SEO help?
Search engines are always working towards improving their technology to crawl the web more deeply and return increasingly relevant results to users. However, there is and will always be a limit to how search engines can operate. Whereas the right moves can net you thousands of visitors and attention, the wrong moves can hide or bury your site deep in the search results where visibility is minimal. In addition to making content available to search engines, SEO can also help boost rankings so that content that has been found will be placed where searchers will more readily see it. The online environment is becoming increasingly competitive, and those companies who perform SEO will have a decided advantage in visitors and customers.
