Well, I can't let priestes take all the heat on this one.
Let me start with some background. During the dot bomb era I was a CMO at a large internet company. As the CMO, it was part of my staffs job to determine the best way to aquire new customers at the lowest cost. Since we could not be everywhere on the internet at the same time, we determined a strategy to divide and conquer (yes, we were conquered alright

) A group of marketeers were responsible for working with feeds and another group was responsible for working with advertising programs, that worked with affiliates. Now, I am a marketing consultant, just not with dot bombs.
My on-line company owns, 3 search engines, so when I say I have banned engines, I have a proof. Mostly, it comes from my questioning the webmaster of the site and their reply pretty much proves their intent or reviewing their TOS. Technically, when I ban a site, an affilate of my search engine is not paid for any search generated from that domain. Unfortunately, if the search affiliate is not paying attention to the banned list and the site that is banned is not honest about the banning, then the advertiser of the portal at that site is being ripped-off by the site owner. This is a sad reality as someone stated in this thread that they have seen an engine run on a banned site.
My on-line company owns, 8 incentivized marketing sites. I run search ads on them. I run ads, not links. I have aquired over 400 affiliates through my search ads. It is not all about searching when you click a link. It is about the ad. You are being paid to read and if you like what you read then you click the link to be paid. If you search on a portal, click a banner link or text ad or sign up as an affiliate yourself then you have responded to the ad.
Now, having said that, if you go back to my CMO days, I as the advertiser in the feed want to acquire customers, so if 1 out of 1000 clicks gets me a new customer, then I could be very happy if the cost for those 1000 clicks did not exceed my budget. I start looking at the feed, where my results are coming from and even at my ad copy on the feed, heck, I may even have the wrong keywords. Usually, I can solve my cost issue with some minor changes in my ad copy or keywords. Trust me, we know you are out there clicking links and not buying, signing up or even really interested. We allow for some percentage of that, because you help us to hone our ads and keywords, you also tell us what part of the country/world our website/offer does not work well, etc.
So, now back to my current on line company. I recently did a bit of testing, lets look at the results so far.
1. New search engine on existing incentivized marketing site. 50 people mailed (targeted search interest in search friendly countries).
42 people clicked the paid link.
4 people became affiliates of the new search engine
7 people searched
9 people clicked a text link on the portal
2. Ran an ad for a freebie (was paid if zip code was entered). 486 people mailed (targeted US)
So far, 292 people have clicked the paid link, one person entered a valid zip code.
3. Ran a text ad for a free sign up on a feed, 1.6 million impressions, for 71 people to click the ad link and 18 people signed up.
4. Ran a text ad for an item that costs money on a feed, 2.8 million impressions, for 52 clicks and no one to-date has purchased the offer.
5. Ran a search link on a site that I do not own. Cost was 75 cents to for 1/4 search link. Targeted to searchers. I received 6 clicks for a total of 19 cents.
6. Ran an ad that did not have a paid link (incentivizing was not allowed) 79 people clicked the link, 5 people participated.
I am looking at 2 for what was wrong, the people that the ad was mailed to or the ad? Maybe, it was a bad offer or the market is saturated with that particular offer.
I am looking at 3 to see if those 18 people will make me enough money over the next 6 months to cover the cost to aquire them.
I am looking at 4 very carefully, as there is something really wrong with this ad, feed, keywords, etc.
I am looking at 5 to determine if it is the site that has a weak database, was it the ad? was it the time of day the ad ran, was it the lack of targeting to search friendly only countries?
I am looking at 6, shaking my head. I thought is was all about the paid link. I guess it must be about the ad.
Overall, it doesn't matter if you are paid to click a link or not, you will respond if you want to. What the feeds are trying to do is help the advertiser get the most from their dollar. Attempting to eliminate searches that will knowingly not result in sale and removes a large element of the unknown factor for ad reponse. Since I as a SE owner get paid per click, I would love to have every searcher click and search on every link, wanting and getting are 2 different things. Clicking to click or searching to search when their is no real interest hurts in more ways than one.
As an SE owner, I am not willing to risk my feeds for risky PTR sites. They are a risk to my SE and they are a risk to my incentive sites. Ever wonder why so many programs have banned incentive sites or incentive clicks? Unfortunately, the 80/20 rule applies here. 20% of the sites are causing 80% of the problem.
I have contacted every site on the list and even offered to remove them from the banned list if they were to make a few changes. So lets not say they didn't know what they were doing because their emails tell me they know exactly what they are doing and none of them have changed their ways.
priestes, sit back and relax for a bit.
