A high Ranking in the Search Engines has no longer the value it had in the past. Search engines regularly change their algorithms and Google even changes them on a daily basis. This means that your high ranking of today can be gone overnight tomorrow and this risk threatens web masters every single day. So you'll have to do more than SEO. One thing you could do is optimize your website for its conversion rate. Just study some documents on the Internet that teach you how to convert website visitors into customers by writing more compelling text and by placing your links at the most strategic locations in your site or blog.

Another and better suggestion to compensate the decrease in value of SEO, is email marketing. Email marketing means that people subscribe to a mailing list and subsequently they are bombarded with numerous follow up messages until they buy something from you. These follow ups are sent automatically by an email autoresponder. There are some good free autoresponders available. However, most good autoresponders are paid services and offer more features than free responders such as unlimited subscribers and unlimited messages. Pricing is around $25 a month and some offer free trials. The most popular auto responder is Aweber, a company that has been active in its industry since 1998.
