Over the past two years, we’ve seen a steady and substantial increase in Featured Snippets on Google SERPs. In our 10,000-keyword daily tracking set, Featured Snippets have gone from about 5.5% of queries in November 2015 to a recent high of just over 16% (roughly tripling). Other data sets, with longer tail searches, have shown even higher prevalence.
Near the end of October (far-right of the graph), we saw our first significant dip (spotted by Brian Patterson on SEL). This dip occurred over about a 4-day period, and represents roughly a 10% drop in searches with Featured Snippets. Here’s an enhanced, 2-week view (note: Y-axis is expanded to show the day-over-day changes more clearly):
Given the up-and-to-the-right history of Featured Snippets and the investments people have been making optimizing for these results, a 10% drop is worthy of our attention.
What happened, exactly?
To be honest, when we investigate changes like this, the best we can usually do is produce a list of keywords that lost Featured Snippets. Usually, we focus on high-volume keywords, which tend to be more interesting. Here’s a list of keywords that lost Featured Snippets during that time period:
- CRM
- ERP
- MBA
- buddhism
- web design
- anger management
- hosting
- DSL
- ActiveX
- ovulation
From an explanatory standpoint, this list isn’t usually very helpful – what exactly do “web design”, “buddhism”, and “ovulation” have in common (please, don’t answer that)? In this case, though, there was a clear and interesting pattern. Almost all of the queries that lost Featured Snippets gained Knowledge Panels that look something like this one:
These new panels account for the vast majority of the lost Featured Snippets I’ve spot-checked, and all of them are general Knowledge Panels coming directly from Wikipedia. In some cases, Google is using a more generic Knowledge Graph entry. For example, “HDMI cables”, which used to show a Featured Snippet (dominated by Amazon, last I checked), now shows no snippet and a generic panel for “HDMI”:
In very rare cases, a SERP added the new Knowledge Panel but retained the Featured Snippet, such as the top of this search for…
