This question does appear on the warrior forum quite often and the responses tend to be split, though the truth is, if your looking for immediate traffic and you have a decent budget, then PPC is definately the way forward.
Using Pay per click via Adwords can generate quite a traffic rush if implemented properly, though the initial daily budget allocation needs to be somewhere near $100 per day within the first week just to guage the traffic for the duration of the campaign.
The major problem with testing PPC Advertising is that you may find yourself losing quite a lot of money at the campaign entry point whilst you’re learning which landing pages work and which don’t, though once you have completed your split testing and start to see sales, you also start to recoup your losses over time (so long as you have performed the correct keyword research for your product).
For the more patient (and perhaps less rich) of the internet marketing crowd, Article Marketing is an ideal medium to build up backlinks to your site, and once combined with some decent SEO stratagies, your website will start to appear at the top of the organic searches in the bigger search engines quite quickly.
As mentioned above, the key to Article Marketing is patience but also a little dedication to your article creation.
If you can write and submit 5 Articles per day to perhaps ezinearticles.com and goarticles.com, your site backlink count will start to soar and as such your page rank and rating within google will start to get you noticed, plus your sales will increase over time without the outlay involved with PPC.
So get submitting those articles now, and please be don’t be tempted to use Article spinning technologies as even though these programs are getting more intelligent, they eventually do create gibberish and will as time goes on get you a bad reputation with the Article Directories who just like google and other search engines are looking for genuine content for their readers.
Article Marketing and Pay Per Click are a big part of Marketing your web based business and it is imperative that you understand both implicitly to guarantee making huge profits online.
