You need to get serious regarding optimizing your website for the search engines-- particularly Google if you want your business to be found by new clients on the Web.
Ranking well in Google's search engine results page can bring a significant amount of new found business. You can learn how to do this yourself-- I did, over a period of 18 years, for the web design and development company I founded, and more recently, doing SEO consulting for clients -- or you can hire someone like me to perform it for you.
Today's SEO requires many capabilities and strategies, from link creation to on-page optimization to conversion testing and click-through rates... and Google algorithms. What worked great even 6 months ago might not work so well now. In fact, it might even get you in hot water : penalized by the search engines.
