Featured Snippets Drop
On February 19, MozCast measured a dramatic drop (40% day-over-day) in SERPs with Included Bits, without any instant indications of recovery. Here's a two-week view (February 10-23):.
Are we losing our minds?
After the year we've all had, it's constantly great to examine our sanity. In this case, other information sets showed a drop on the very same date, however the intensity of the drop differed significantly. So, I checked our STAT data throughout desktop questions (en-US just)-- over two million daily SERPs-- and saw the following:.
While mobile SERPs in STAT revealed higher total prevalence, the pattern was extremely comparable, with a 9% day-over-day-drop on February 19 and an overall drop of about 12% considering that February 10. Note that, while there is significant overlap, the desktop and mobile information sets might contain various search phrases. While the desktop information set is currently about 2.2 M everyday SERPs, mobile is closer to 1.7 M.
Note that the MozCast 10K keywords are skewed (deliberately) towards shorter, more competitive phrases, whereas STAT includes a lot more "long-tail" phrases. This explains the general greater occurrence in STAT, as longer phrases tend to consist of questions and other natural-language queries that are most likely to drive Featured Snippets.
Why the huge distinction?
What's driving the 40% drop in MozCast and, most likely, more competitive terms? While some changes effect market classifications similarly, the Featured Snippet loss showed a significant variety of effect:.
Competitive health care terms lost more than two-thirds of their Included Snippets. It turns out that a lot of these terms had other prominent functions, such as Medical Understanding Panels. Here are some high-volume terms that lost Featured Snippets in the Health classification:.

lupus.
autism.fibromyalgia.
acne.While Financing had a much lower initial prevalence of Included Bits, Financing SERPs also saw enormous losses on February 19. Some high-volume examples consist of:.
pension.
threat management.mutual funds.
roth individual retirement account.financial investment.

Both Health and Finance search expressions align carefully with so-called YMYL (Your Cash or Your Life) material locations, which, in Google's own words "... could potentially impact an individual's future happiness, health, financial stability, or security." These are locations where Google is clearly concerned about the quality of the responses they supply.
What about passage indexing?
Could this be tied to the "passage indexing" upgrade that presented around February 10? While there's a lot we still do not learn about the impact of that upgrade, and while that upgrade affected rankings and very likely impacted organic snippets of all types, there's no factor to think that update would affect whether or not a Featured Bit is shown for any provided inquiry. While the timelines overlap a little, these events are most likely separate.
Is the snippet sky falling?
While the 40% drop in Featured Snippets in MozCast appears to be genuine, the effect was mainly on shorter, more competitive terms and specific industry classifications. For those in YMYL classifications, it definitely makes good sense to assess the effect on your rankings and search traffic.
Normally speaking, this is a common pattern with SERP functions-- Google ramps them up gradually, then reaches a limit where quality starts to suffer, and then lowers the volume. As Google ends up being more confident in the quality of their Included Bit algorithms, they might turn that volume back up. I definitely don't anticipate Featured Snippets to vanish whenever quickly, and they're still extremely widespread in longer, natural-language questions.
Think about, too, that some of these Included Best SEO on the Gold Coast Bits might simply have actually been redundant. Prior to February 19, somebody looking for "shared fund" may have seen this Featured Snippet:.
Google is presuming a "What is/are ...?" concern here, however "mutual fund" is a highly ambiguous search that could have multiple intents. At the very same time, Google was currently showing an Understanding Chart entity in the right-hand column (on desktop), probably from trusted sources:.
Why display both, specifically if Google has concerns about quality in a classification where they're very conscious quality issues? At the same time, while it may sting a bit to lose these Featured Bits, consider whether they were really providing. While this term may be terrific for vanity, how often are people at the very beginning of a search journey-- who may not even know what a shared fund is-- going to convert into a customer? Oftentimes, they might be jumping straight to the Understanding 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 Functions" page (under "Rankings" in the left-hand nav) and filter for keywords with Included Bits. You'll get a report something like this-- search for the scissors icon to see where Featured Bits are appearing and whether you (blue) or a competitor (red) are capturing them:.
Whatever the effect, something remains real-- Google giveth and Google taketh away. Unlike losing a ranking or losing a Featured Snippet to a rival, there's extremely little you can do to reverse this type of sweeping change. For sites in heavily-impacted verticals, we can just monitor the circumstance and try to evaluate our new reality.
Update: Visit word-count.
I recognized that we might take a look at word-count in the STAT data to evaluate the theory that much shorter search queries (which are usually both more competitive and more uncertain) were hit harder by this upgrade. Here's the breakdown of STAT's 2M desktop (en-US) keywords ...
There's very little nuance here-- 1-word queries were clobbered in this upgrade, 2-word inquiries dropped considerably greater than the STAT average, and 3+- word queries were struck much less. Why these queries were struck isn't as clear, however the influence on really short queries is clear.
