Register with Paid Directories - While there are several free web-directories out there, take the time to register with paid directories. You will get efficient service and a quick link back to your site. Some of these directories may even send you some traffic - but that is not the intent here. Your goal is to get some callback links and get those Search Engine robots active, as well as add some credibility to your site.
Pay per Click (PPC) - Probably one of the most well-known and hailed methods to generate instant traffic to your site is to advertise with Google AdWords or Yahoo!. These advertisements generate instant traffic to your site and are seen widely across their networks. There is much that is written on this subject, including at marketingexperiments.com, one of our favorite sites on this subject. You must master the management of a PPC campaign; otherwise you stand to lose much money without reward. Ensure that your product and website are well-crafted and ready to "suck in" the cash - and do plenty of testing before making your big launch.
Advertising through other Vendors - As our report on Google AdSense indicates, you can advertise through other vendors such as AdBrite and BidClix, who will help you manage your campaign and allow you to advertise on their network of selected sites. These sites tend to be targeted as well as have high traffic. Of course the cost of advertising is higher as well - but you have to be the final judge of each marketing channel by comparing the revenue produced per channel versus cost of marketing through each channel.
Online Press Release Campaign - Creating effective press releases and maintaining an online campaign provides you with credibility, exposure and some back-links from highly ranked sites. If the product or service you are offering has a mass or niche appeal, it is more likely than not that to be picked up by services that cater to that market. This in turn increases exposure and will bring additional traffic to your site. The long term benefits of running a meaningful and sustained press release campaign cannot be overstated. Use services such as prweb.com to publish your press releases. However, you have to have a quality product before you start such a campaign. Everyone is looking to report on extremely useful quality services - in fact they are practically hungry for it! So work on your product first, and then launch a press campaign.
Using these techniques, you will begin building a stream of ongoing, qualified traffic to your site, which is the lifeblood of any online enterprise.
