6sync VPS Hosting
by adam on July 10, 2011
Big thanks to Mario at 6sync for making my transition of my VPS over to 6sync a seamless experience last week.
After a bit of tweaking, we got everything running smoothly on my brand new server, for half the price
I was paying for a comparable VPS at slicehost.
Can’t recommend these guys highly enough.

In A/B testing there is no such thing as a free lunch.

In A/B testing, as is the case in the rest of economic life, there is no such thing as a free lunch.
In my experience, most split and multivariate tests are set up to maximize for a certain goal, e.g: registered users or email subs, but often fail to account for the un-intended consequences of such “optimizations”. The problem with changing your ui to try and maximize for one of these goals is that you are failing to measure the dis-utility that often gets created by cluttering or fragmenting the continuity of your interface or landing page.
For example, say I am trying to increase visits and awareness of a new feature of my product by adding a link to it on my homepage. Typically an experiment would be constructed by adding a new ui element and testing it’s copy/color etc that call attention to the new call-to-action that I am trying to optimize for. The problem with this kind of test is that by only measuring click-throughs to my new product page, I miss measuring the missed attention that was not given to another part of my interface.
Since the attention of the website visitor at any given moment is a finite resource, it is impossible to add something without detracting something at the same time. I have yet to see an a/b testing framework that accounts for this by default.
The end result is a bunch of “maximized” local optimums that don’t look or behave cohesively and often appear ugly, as I would imagine is likely the case with plenty of fish.

Is advertising via Facebook as effective as Google Adwords?
by adam on January 31, 2011
In my experience the problem with the facebook advertising platform is that it doesn’t effectively allow for different types of advertisers to compete on an even playing field.
You could make the argument that since they allow for all different types of interest/demographic bidding, that there are many micro playing fields for different types of advertisers to compete on, but this analysis fails to capture the one most important vector that drives internet advertising, which is intent.
The beauty of Google’s adwords platform is that for any given keyword, a one-man custom boot making shop in Texas can profitably compete against internet retail giants such as Amazon because for certain keywords the intent of the searcher is more aligned with their product offering than Amazon’s.
In a generalized second-price auction such as Adwords, since advertisers are attempting to maximize their ROI on a per-keyword basis, they are not perversely incented to maximize their CTR at the expense of receiving lower CPC’s and an increase in less qualified traffic.
On the other hand, on the facebook advertising platform, different types of advertisers who will have wildly different costs for customer acquisition are competing for impressions and clicks head-to-head. This in turn causes two kinds of major distortions in the marketplace:
1) Advertisers with the highest customer acquisition value will eventually rise to the top, crowding out the smaller guys. e.g: you will see more ads for attorneys and real estate agents then you will for restaurants and dry cleaners.
2) Ad Copy / Images will trend towards becoming more and more attention grabbing in a never-ending arms race towards a higher CTR = lower CPC.
In the long run, neither of these two attributes is conducive to a robust and sustainable advertising platform for facebook.
