As you buy clicks on Google, offer those people something of your very own first, something of genuine value that nobody else can replicate. Collect contact information from as many of those visitors as you possibly can, then send them on.
Customarily, if 5 or 6 years produces a 'custom', affiliate partners have put out ad banners or link exchanges, paid for ppc traffic and others, and then sent that traffic to the affiliate hoping for sales that he can get commissions from.
People like this are known as 'bitslingers'. Bitslingers buy traffic and make a profit sending it on to their affiliate, nothing more. They don't 'make the world a better place'. They just 'sell' their traffic. Do you have higher aspirations that that? Construct a valuable customer list that you can have future transactions with.
What could you do to take a valuable product and add some value of your own to it? Here are some suggestions:
Present an enlightening tutorial.
Do a substantive teleseminar on a topic that would be a natural, unassuming segue to the affiliate product or service that you're promoting.
Set up your own site that provides a multiday e-mail course about your topic, and promote your affiliate program that way.
Offer a free guide or reference material.
When you are affiliated with more than one similar product, produce a compare and contrast analysis on the products or services cost and quality then let your customer choose.
Make an MP3 recording on your topic.
Hold a contest.
Furnish some type of downloadable software.
It is important that you refrain from screaming, "buy this!" to your customers. Give them something they can use to improve their business or life then they will want to see what product you are offering.
Time was you could purchase traffic(clicks) from Google, and point them through your links on to the affiliate host website. Prosperous affiliate hosts thought this was great especially when they had dominance in their field when nearly every Google ad shown talked about their website.
Google saw things differently. Stranglehold setups like that ruined the whole experience of using AdWords and made Google look bad. So in early 2005, it put a stop to it. The policy now is that only one advertiser per display URL can show up on any one page of AdWords listings.
What this does mean though is that your affiliates can be on that same page of Google results. It also means that you aren't allowed to push traffic directly to your affiliate host's website.
So your affiliates-or you yourself, if you're an affiliate for another host-need to come up with real, original content on the landing page, if you want to survive. When you do this, everybody wins. You add value to the market, and those visitors who sign in become an asset for you.
