I wrote at the beginning of November about the results of some experimental clicking to see if Entrecard was delivering only the 15% of ads for their system which they claimed. Using the methods that I chose at that time to load the blog pages, the ad rate did work out to 15%.
But some questions were raised about other methods of serving blogs, so I decided to so some further research today. It was quite enlightening.
First I opened 100 blogs in the Entrecard system by using the EC toolbar. My selections for the type of blogs to open were from several categories that interest me, and the list was further filtered by "Most Popular." I often click this way, knowing that those bloggers are likely to reciprocate and visit my blog. For 100 blogs, there were 16 EC ads. This is certainly within the margin of error, although it is interesting to note that all 15 were served by the time I had opened 80 pages. In the 100 pages opened, 2 of them had no widget, which I thought was pretty interesting for a blog that had made it into the top 20 in a category (I chose 20 from each of 5 categories). I did reload each of those 2, to be sure that the widget really wasn't there.
But when I switched strategies, I really had an eye-opening result. I did two more sets of 100 blogs each, served by the EC widget. But for each of these sets I chose All and Random for the parameters of the search. This should have given me an unbiased sampling of whatever types of blogs are members of the EC network. Here's what I found:
First set:
A. Blogs served- 100
B. EC ads- 39 (39% or 44%- see conclusions)
C. no widget- 22 (one could reasonably expect that a small number of blogs would be so new to EC that they have been approved but not yet added a widget, but certainly not 22 of them. Of the 22, 2 were simply non-existent, 404 file not found errors.)
Second set:
A. Blogs served- 100
B. EC ads- 38 (38% or 43%- see conclusions)
C. no widget- 22 again (see comments above. One blog was by invitation only, one had a suspension notice. One other blog actually had a widget but I reported it for being over MY pornography threshold!)
Conclusion- if you say that I only viewed 88 (100-22) blogs in each set then the percent of EC ads is 39/88 = 44% or 38/88 = 43%! If I had discounted the 22 blogs that served no ads, for whatever reason, and continued to load blogs by this method to get 22 more valid views, even if all 22 had no EC ads, the ads would still have been 39% and 38%. Since it is more likely that there would have been some EC ads, the percentage would have gone even higher. For example, if in those 22 additional blogs, 5 had EC ads, then the percent would have been 44/100 = 44%.
For this level of ads, which is 2.5 times higher than they claim, there would need to be 500 blogs loaded with no EC ads at all to bring the percent back down to 15. Statistics is all about probabilities, and although this is possible, it is highly unlikely! Is there some little known way to load blogs whereby few or no ads are served? Perhaps I should try more sets with Favorites and Most Expensive?
To look at this another way, of the last 200 blogs I tried to open, only 156 of them had an EC widget on which to drop. Of the 156, only 79 actually had ads from other blogs in the system. That is 51%. If EC members are only shown ads from other blogs half the time (admittedly by this one method of blog delivery), no wonder they are upset.
And this is all on top of the fact that there are currently 10 paid ads in the system. I simply counted them as valid widgets that don't go to EC, but still reduce the amount of control that a blogger has over the ads which appear on his or her blog. One can choose to have up to 5 of those not display, but to remove them completely, you have to pay $48 a year and subscribe to Entrecard. This seems pretty far removed from the means of "free" blog promotion that Entrecard touts to potential members.
