Creating PURL web designs as landing pages to the rest of your website is a great tactic to drive up conversion rates but if you want still more traffic flowing into your website, use Pay-Per-Click as part of your online marketing strategy.
One of the most powerful tools available for driving traffic to your website is Pay-Per-Click advertising. This is the practice of paying search engines to list your website at the top of search engine ratings. Normally a Pay-Per-Click link is located in a special area of the search engine results reserved for promotional links - an area labeled as such so visitors know your link is paid for. There is statistical drop in the number of people who click on Pay-Per-Click links as opposed to what are perceived of as "genuine" or "legitimate" links but you are not charged for the number of people not using the link. You only pay for guaranteed traffic.
As the name suggests, the profit model is based on the number of times a visitor clicks and actually follows a link to your website. You are not charged for having the link present in search engine results.
If someone knows your link is paid for but follows it anyway, the chances are actually quite reasonable that he will convert to being a paying customer. Obviously he is interested in a purchase if he clicks on a clearly commercial link.
Pay-Per-Click marketing is not something you have to maintain forever. It's a quick way of generating traffic. Traffic drives up your search engine ratings. Driving up your ratings increases traffic to the point where eventually, you don't need pay-per-click advertising to stay up there in the rankings. Traffic buoys up your search engine rankings.
