Google Content Network Defined
The Google content network comprises millions of websites, news pages, and blogs that partner with Google to display targeted AdWords ads. Ads to the content network are targeted based on content themes rather than specific keywords as is done on the search network. Unlike a keyword search which is well defined, a content match may not display your ad on the site you had in mind resulting in clicks you prefer not to have.
Identifying the Sites that Don’t Convert
On June 1st last year, Google made available a report that tells you which sites are not converting. You can run this report at the ad group or the campaign level for a domain or a url. Once you run the report you can feed the results into the Site Exclusion option in the Tools section. This will cause the domains or url-s you designate to not show your ad resulting in a better use of your ad dollars.
Further Analysis
This on the surface appeared to be an excellent opportunity for one of our clients to save a few dollars. After running the report for all the ad groups we learned there was about $1,075 that could have been saved in June if the sites with no conversions had been excluded. Upon further analysis we determined that some sites did not convert for some ad groups but did convert for others. Since the Site Exclusion option does not allow exclusions at the ad group level we had to revise our plan to exclude the non performing sites at the campaign level.
Still Not Bad
The initial excitement over the potention savings abated somewhat. Instead of the $1,075 a month savings that we had anticipated from excluding non performing content network sites, we will save about $521 a month. We have to factor in that this is just one month’s worth of data but it is still encouraging when you consider a year’s savings would equal $6,252. Is it worth a try or is there still more analysis we should do?
One Additional Thought
The thought that one month’s worth a data is not enough to make a decision stayed on my mind. On one hand we may be paying more than we have to each day. On the other hand we may be making decisions on incomplete data. Thinking it through it seems logical to conclude that if a domain or url doesn’t convert then don’t spend money on it. The only down side would be if it converts later we would miss a conversion. But what impact would 1 or 2 conversions have when we are talking about 100 conversions a day.
An Aha Moment
Then it occured to me. Most of the conversions orginate from a few domains or URLs, but the bulk of the conversions come from many domains or URLs. It is the old numbers game. In the reports there were thousands of domains and URL-s that had only 1 or 2 conversions for June. The number of sites that had just 1 or 2 conversions were not the same domains and URL-s that had only 1 or 2 conversions in July. If I had excluded the non converting domains and URL-s that had no conversions in June we would have eliminated 100-s of conversions in July.
My Conclusion
Based upon this data I concluded that sites should not be excluded simply because they don’t have conversions. Another criterion should be placed on top of this that is simular to the cost per acquisition (CPA) measurement. With the CPA you assign a dollar amount to what a conversion is worth. If it is worth $40 is get a new customer, $40 worth of clicks to get it is acceptable. Simularly if the non converting sites are costing you a few pennies a month to keep them then it may be wise to do so. If they are beyond a thresshold you determine to be unacceptable, then by all means exclude them. As with a CPA, some conversions are not worth the price.
