Featured Snippets Drop
On February 19, MozCast determined a dramatic drop (40% day-over-day) in SERPs with Featured Bits, without any immediate signs of recovery. Here's a two-week view (February 10-23):.
Are we losing our minds?
After the year we have actually all had, it's always great to inspect our sanity. In this case, other data sets revealed a drop on the same date, however the intensity of the drop varied drastically. So, I examined our STAT information throughout desktop inquiries (en-US only)-- over two million daily SERPs-- and saw the following:.
While mobile SERPs in STAT showed higher overall frequency, the pattern was really comparable, with a 9% day-over-day-drop on February 19 and a total drop of about 12% given that February 10. This discusses the overall higher occurrence in STAT, as longer phrases tend to include concerns and other natural-language queries that are more likely to drive Featured Snippets.
Why the huge difference?
What's driving the 40% drop in MozCast and, probably, more competitive terms? While some modifications effect industry classifications similarly, the Featured Snippet loss showed a dramatic range of effect:.
Competitive healthcare terms lost more than two-thirds of their Included Bits. It ends up that much of these terms had other prominent features, such as Medical Knowledge Panels. Here are some high-volume terms that lost Featured Snippets in the Health category:.

lupus.
autism.fibromyalgia.
acne.While Finance had a much lower initial occurrence of Featured Snippets, Finance SERPs also saw huge losses on February 19. Some high-volume examples include:.
pension.
risk management.mutual funds.

financial investment.
Like the Health category, these terms have a Knowledge Panel in the right-hand column on desktop, with some fundamental information (primarily from Wikipedia/Wikidata). Once again, these are competitive "head" terms, where Google was showing several SERP functions prior to February 19.Both Health and Finance search phrases line up carefully with so-called YMYL (Your Cash or Your Life) material locations, which, in Google's own words "... could potentially impact a wordpress websites gold coast person's future happiness, health, financial stability, or security." These are locations where Google is plainly worried about the quality of the responses they supply.
What about passage indexing?
Could this be connected to the "passage indexing" update that presented around February 10? While there's a lot we still do not know about the impact of that update, and while that upgrade affected rankings and highly likely affected organic snippets of all types, there's no factor to think that update would impact whether an Included Bit is displayed for any offered question. While the timelines overlap somewhat, these events are probably different.
Is the bit sky falling?

Typically speaking, this is a typical pattern with SERP functions-- Google ramps them up in time, then reaches a limit where quality starts to suffer, and then reduces the volume. As Google ends up being more confident in the quality of their Included Snippet algorithms, they may turn that volume back up. I certainly do not anticipate Included Bits to disappear whenever soon, and they're still really common in longer, natural-language inquiries.
Think about, too, that a few of these Featured Snippets may just have actually been redundant. Prior to February 19, somebody looking for "mutual fund" might have seen this Included Bit:.
Google is presuming a "What is/are ...?" concern here, but "shared fund" is an extremely ambiguous search that might have several intents. At the very same time, Google was currently showing an Understanding Chart entity in the right-hand column (on desktop), presumably from trusted sources:.
At the very same time, while it might sting a bit to lose these Featured Snippets, think about whether they were truly delivering. In lots of cases, they may be leaping straight to the Knowledge Panel and not even taking the Included Bit into account.
For Moz Pro clients, bear in mind that you can quickly track Included Snippets from the "SERP Features" page (under "Rankings" in the left-hand nav) and filter for keywords with Included Snippets. You'll get a report something like this-- look for the scissors icon to see where Included Snippets are appearing and whether you (blue) or a competitor (red) are recording them:.
Whatever the effect, one thing stays true-- Google giveth and Google taketh away. Unlike losing a ranking or losing an Included Bit to a competitor, there's extremely little you can do to reverse this kind of sweeping change. For sites in heavily-impacted verticals, we can just keep track of the scenario and try to examine our new reality.
Update: Visit word-count.
I realized that we could take a look at word-count in the STAT information to test the theory that shorter search inquiries (which are typically both more competitive and more unclear) were struck harder by this upgrade. Here's the breakdown of STAT's 2M desktop (en-US) keywords ...There's not much nuance here-- 1-word inquiries were clobbered in this update, 2-word queries dropped considerably higher than the STAT average, and 3+- word inquiries were struck much less. Why these questions were hit isn't as clear, but the impact on extremely short inquiries is clear.
