PPC & attribution experts only. This requires a deep understanding of search and an obsessive passion for paid digital media. I expect some negative feedback on this. Allow me to indulge 😉
Studying the path length reports in the search attribution tool showed us that generic queries almost always convert combined with branded queries. We can hence assume that the data driven algorithm that is looking at numbers would consider branded keywords pretty important.
Upon comparing data driven attribution to first click attribution through the attribution tool, the following happened:
When showing this to the client, they were schocked. Nobody cared about the cost/sale of the branded keywords decreasing from 4 eur to 2 eur. The cost per sale of generic keywords that increased from 100 eur to 300 eur in the data driven model was however enough to leave them gobsmacked.
Statistically speaking, I’m sure the data driven model is correct. If it is providing weight to the number of times a specific query appears in the customer journey, than obviously branded queries will get a lot of weight. As data driven attribution will then decrease conversions on generic keywords, ROI sensitive clients will decrease bids. Branded queries will then become even more prominent, and the whole thing becomes a self-fulfilling prophecy.
From an outcome-driven marketing & “lets grow revenue” point of view, this makes no sense. Cost per sale on branded search moved from cheap to too cheap to care, while generic cost per sale increased by 3 compared to a first click attribution model. Meanwhile, the site is ranking very well organically on all branded search queries and has limited competitors bidding on their brand.
As a result, the actual value of generic queries is massively undervalued due to the presence of the branded queries in the account. Is is highly likely that the client would have gotten the sales that happened on the branded query through organic search anyway.
So if datadriven is not taking the less important role of branded search queries into account on sites that are ok SEO wise, and uses frequency of search queries in the customer journey as a factor in the algorithm, we can expect ROI sensitive PPC managers to decrease overal media spend in the long run, as they decrease investment on generic terms. That can’t be the goal.
I’ve seen this happen several times now on pure ecommerce players. They fail to scale the accounts, especially in smaller markets with products/services that have decision cycles beyond several days.
In both scenarios’s, by taking branded queries out of the account, conversion attribution will shift back to generic keywords and data driven will do its work on generic queries alone.
Sales and media spend on generic search queries will go up while overall sales from organic and paid search combined should increase.
In any case: before using data driven, check the importance of branded search queries in the account. If your sales are primarily coming from branded queries, and you wish to keep them in the account – you’re probably better off with first click attribution…(the horror!)
Of course, savvy digital marketeers should be going beyond that and look for attribution tools that take the incremental value of branded search queries and all forms of remarketing into account across the entire media mix…
