There are many misconceptions of how Adware behave and how they can impact on both Affiliate and Merchant web sites. There are hundreds of known adware applications being downloaded and installed on end user's computers. There are also many not yet identified adware applications being downloaded and installed. Adware can and does frequently change the way in which they behave on the end user's computer. With that in mind, we will discuss the major classifications that AFP uses to categorize adware and the manner in which they can potentially impact both affiliate's and merchant's web sites and revenue. We will restrict the discussion to potential impact on affiliates and merchants and leave the discussions focusing on consumer impact to others.
Contextually-based adware can ultimately behave in a variety of ways (i.e. pop ups, browser redirects). The one common factor for all contextual adware is their behavior is dictated by the content from the web site the end user is viewing. Depending on the adware application, the triggering content can be such web page components as: domain name, page name, meta tags, text contained in header attribute tags and even the text on the viewed page. Contextually-based adware requires at least one piece of information about another's web site that is being viewed by the end user to determine whether to activate the software and which ad to call into action.
Impact To Affiliates:
These applications are associated with rebate web sites which act as a 'reminder' to the consumer that they can be receiving either a portion of their purchase back as a cash rebate, have a portion of their purchase given to a charity or be earning 'points' based on their purchase which are redeemable for products/services. They generally activate once on the Merchant's web site and not on the Affiliate's web site (although they can activate on the affiliate's web site and have done so in the past). They can either automatically redirect through their affiliate link once on the Merchant's web site informing the consumer they are receiving their reward or present prompting for the end user to click their affiliate link if the consumer wants their reward. Many of these applications will function if the consumer is not registered with their service to receive the reward.
Impact to Affiliates:
These applications deliver advertising but the ads are not necessarily targeted to the content the end user is viewing (i.e. untargeted). The ads can occur at anytime not only when the end user is surfing. A variety of ad delivery mechanisms can be used including pop ups, pop unders, pop behinds, and sliders. Since the advertising is not targeted, the adware tends to generate more ads than the contextually based applications. It is also less common to see affiliate tracking links with these applications as advertisers paying by CPC or CPM are preferable with the frequency of ads displayed.
Impact to Affiliates:
Toolbar may seem rather self explanatory however they can encompass a rather wide range of behaviors from innocuous to invasive. Some toolbars amount to glorified bookmarks. Others may provide a one-step access to search results. However, others may generate pop-ads, browser redirects or other questionable behavior.
As the behavior of toolbars can vary widely, the impact on affiliates and merchants varies accordingly. As such we will not attempt to list all the possible impacts. Toolbars present a unique challenge as there are literally thousands of toolbars available now and the degree to which their behavior can vary.
Browser redirect applications take control of the end users browser and automatically direct the browser to a web page that the end user has not willfully chosen by clicking on a hyperlink. Many times these applications do not generate pop up ads and therefore it may not be as obvious to end users that the application is installed. One example of this type of application is 404 error/name resolution redirect application. Another example are applications which automatically redirect the browser their affiliate URL without any type of promotion of the Merchant.
Impact to Affiliates:
Site Upgrade
We are about three-quarters of the way through a complete backend site upgrade and site redesign. For a few reasons, we are making these changes in alive environment. Yeah...we know that's not the way it's supposed to be done, but what the heck things happens sometimes.
If you see some strangeness, no worries it will most likely go away before long. On the bright side, you get to see our production in real-time along with all of our "oops that's not what we meant to do".
