Google’s Content Theming
July 24th, 2007
I used to think that the Google content network operated kind of like their search network…people searched on a keyword, and when they visited a site that was relevant (which displayed Adsense), then the Adsense ads would be based on the keyword the user initially entered. After all, why use the Broad, Phrase or Exact match options on your keywords running on the content network, right?
Well I was ‘illuminated’ a while back by the kind folks over at google (adwords reps) who told me that while Google takes into consideration your ad text, URL link and landing page factors to generate your infamous ‘Quality Score’ (they don’t show your score for the content network), that where and when they actually present your ad on their content network sites is based on the “theme” of your keywords within an adgroup…
Huh? was my initial response, but they clarified this further by telling me that each adgroup within your campaigns running on the content network has a certain ‘theme’, and if your keywords aren’t tightly related to each other, or you have much more than about 10-20 keywords in an adgroup, then the Google computers can have trouble determining a theme for your particular adgroup, and that can affect how it is displayed across the content network.
My eyes glazed over initially as I strained to process this data, but then the importance of ‘theming’ my adgroups by only including about 10 keywords began to sink in, and I realized that I had some ‘account maintenance’ ahead of me!
I switched to using Adwords Editor a while ago, and so making organizational changes to my campaigns was fairly easy. I already understood the necessity of focused and related keywords within an adgroup (Yes, I’ve read Perry Marshall among others), but there just isn’t very much good info out there on how to properly optimize for the content network.
I’ve been told by some ‘Super Affiliates’ that you can go ahead and throw a hundred keywords into your content adgroups and leave them on Broad Match…of course they were probably laughing after giving such advice, knowing that I wouldn’t be any competitive threat to them in the near future!
My Google adwords rep also told me that if you want to see even better performance in drawing highly targeted visitors from content ads that will convert better, then continue growing and refining your keyword list. As you grow your keyword list from hundreds to tens of thousands of keywords, then your content adgroup themes will get even ‘tighter’ and will appear on even more relevant websites, thus brining in higher conversions. My personal preference is to use “phrase matching” on most of my keywords in the content network…this prevents my ads from being shown on many irrelevant sites.
Google’s content network currently accounts for 90% of my affiliate sales volume (some products convert better on the content network than search, funny as that might seem). Has anyone else had great success with Google’s content network? If so, please share.
