When companies run offline advertisements (radio, newspaper, TV,etc.) this often spurs people to go online and do a search for your company. What this should tell you is you better be there at the top of the search results for your company name, as well as variations of your company's name. If you don't have a web site or your site is not properly optimized so you don't show up in the search results you could be driving potential customers to your competitors. In times like this it can really pay to have your web site search engine optimized.
