Recently, the American Customer Satisfaction Index reported that the perceived quality of Google and other search platforms is on a downward trajectory. In particular, Google’s satisfaction score has declined two percentage points to 82 out of a possible high score of 100, according to the ACS Index.

Related to this trend, search advertising ROI is also declining. According to a report published recently by Analytic Partners, the return on investment from paid search dropped by more than 25% between 2010 and 2016.

In all likelihood, a falling ROI can be linked to lower satisfaction with search results.  But let’s look at things a little more closely.

First of all, Google’s customer satisfaction score of 82 is actually better than the 77 score it had received as recently as 2015. In any case, attaining a score of 82 out of 100 isn’t too shabby in such customer satisfaction surveys.

Moreover, Google has been in the business of search for a solid two decades now – an eternity in the world of the Internet. Google has always had a laser-focus on optimizing the quality of its search results, seeing as how search is the biggest “golden egg” revenue-generating product the company has (by far).

Obviously, Google hasn’t been out there with a static product. Far from it:  Google’s search algorithms have been steadily evolving to the degree that search results stand head-and-shoulder above where they were even five years ago.  Back then, search queries typically resulted in generic results that weren’t nearly as well-matched to the actual intent of the searcher.

That sort of improvement is no accident.

But one thing has changed pretty dramatically – the types of devices consumers are using to conduct their searches. Just a few years back, chances are someone would be using a desktop or laptop computer where viewing SERPs containing 20 results was perfectly acceptable – and even desired for quick comparison purposes.

Today, a user is far more likely to be initiating a search query from a smartphone. In that environment, searchers don’t want 20 plausible results — they want one really good one.

You could say that “back then” it was a browsing environment, whereas today it’s a task environment, which creates a different mental framework within which people receive and view the results.

So, what we really have is a product – search – that has become increasingly better over the years, but the ground has shifted in terms of customer expectations.

Simply put, people are increasingly intolerant of results that are even a little off-base from the contextual intent of their search. And then it becomes easy to “blame the messenger” for coming up short – even if that messenger is actually doing a much better job than in the past.

It’s like so much else in one’s life and career: The reward for success is … a bar that’s set even higher.
