The PPC Cinderella
Most people who have some experience with PPC marketing will be able to tell you all about ROI, CPCs, conversion tracking and the likes. They will also tell you that adcopy is important and that it is a good idea to test adcopy variations to see which one performs the best. But as adcopy goes, that is where most marketers’ knowledge stops.
Most aspects of PPC are easily quantifiable which is why this marketing channel is so successful. You can measure exactly how much revenue your advertising spend is generating. But beneath the clarity of ROI, there a lot variables (known and unknown) at play. Variables which cannot as easily be measured.
The Cinderella of these variables is definitely ‘the adcopy’. Although search engines do try their best to assign a quality score to the adcopy, this quality score is only relevant to the advertiser because of its impact on the eventual CPC. It is nearly impossible to measure the impact of the adcopy on the psyche of the search engine user.
Forget about your portfolio of keywords, your adcopy is what users will eventually see in their search results. It is your virtual shop window and you should take great care in designing it. Unfortunately, search engines often have different ideas of what constitutes good adcopy.
For instance sometimes adcopy with a relatively low CTR proves to have an excellent conversion rate. This would be the type of adcopy preferable to an advertiser, because it reduces the amount of unqualified traffic. In a PPC model however, search engines have little incentive to reward adcopy with low CTRs. Cost per Acquisition (CPA) models should therefore gain more and more ground in the future as they align quality scores with advertisers’ goals.
Untill that happens though (Google’s CPA model is only in beta so far) don’t give up on experimenting with your adcopy. I would always focus on adcopy that converts best, and ignore quality scores initially. Once you know what it is that entices your visitors to convert, you can always try to make your adcopy more search engine friendly or create dedicated landing pages tailored to your adcopy.
By taking this approach, we managed in some cases to create adcopy with a CTR and conversion rate identical to the initial one but with an average CPC that was 30% less (and this without altering the keyword bids). Just play with the length and the phrasing of your ads without changing its meaning and you will be surprised at the impact on your CPCs.
Some people like to ignore adcopy optimization because of its unquantifiable properties but when you think of it, it is what makes search engine marketing an art rather than ‘just’ science.
