Google Adwords can be used to drive targeted traffic to a sales page. You simply make an ad in your adwords account then use your affiliate link in the target page URL of the ad. Obviously, you will have to continuously measure the conversions and see if the campaign cost is less than the campaign profit in order to keep the campaign running but I am sure you get the idea.
Affiliates need a marketing angle of substance. Having a website that is niche-specific is a good starting point. I see many affiliates with a good idea; however, they make the mistake of adding coupon codes to their site. They think this will add some value to their offer but, most of the time, it takes away value. Coupon code sites are a dime a dozen and this only reduces the commission rate a merchant is willing to pay. There are already big players that offer coupon codes and most are willing to accept a commission of 1 percent or less. You should think twice before offering or including coupon codes on your website. More times than not, it ends up hurting your earning potential rather than helping it.
All of the above info is for those of you who want to learn affiliate marketing for free. As you can see, there is a lot of free help for you if you plan on doing all of this yourself. However, I also know that some of you do have some funding available and you want to create a bit of a shortcut to success. The only way to do that is to outsource right now.
There are more than half a billion active websites under the sun and most of the (almost 70%) of them struggle to get traffic due to the high competition and expense of the process like SEO or Digital Marketing. However, you can simple buy targeted traffic from various sources at any time you want! Every paid ad campaign is an attempt to get traffic in exchange of money. However the reasons behind getting traffic are pretty different from each other. Some people buy traffic to get sales, some buy traffic to get leads, some buy traffic for brand exposure, some buy traffic to gain authority and improve rank on several metrics and so more.
