Google has an incentive to group advertisers in ad auction even when this conflicts with the goals of an individual advertiser. For example, you’d like to bid on ‘term x‘ and would not like be included in auctions ‘term x+n‘ due to e.g. lower relevance, your ad might still participate in the auction. This relates to two features: use of…
Introduction This is a simple post about some commonly known features of online ad auctions. Generalized second-price auction (GSP) is a mechanism in which the advertiser pays a marginally higher bid than the advertiser losing to him. It encourages the bidder to place a truthful bid, i.e. one where the price level is such that marginal returns equal marginal cost.…
Introduction Google has made a major change in AdWords. Ads are now shown only in the main column, no longer in the right column. Previously, there were generally speaking eight ads per SERP.

I told him the plan should include certain elements, and only them (it’s easy to make a long and useless plan, and difficult to do it short and useful). Anyway, in the process I also told him…

This is done to determine a) business potential and b) channel potential. The former refers to how lucrative it is to acquire customers given their lifetime value, and…
Update [24th March, 2017]: In addition to the formula explained in the post, I would add the following general criteria for a good AdWords case: 1) Low-Medium competition (high CPCs force to look for alternative channels), 2) Good website/landing pages (i.e., load fast, easy to navigate, have text information relevant to the keywords. Introduction Google AdWords is a form of…
I teach this very simple formula to my students when they are required to write a pre-campaign report for the Google Online Marketing Challenge (GOMC). You want to report metrics in a table like this: budget ctr cpc clicks impressions 250 0,05 0,2 1250 25000 (The numbers…
