Included Snippets Drop
On February 19, MozCast measured a dramatic drop (40% day-over-day) in SERPs with Included Snippets, without any immediate signs of healing. Here's a two-week view (February 10-23):.

Are we losing our minds?
After the year we've all had, it's always good to examine our sanity. In this case, other data sets showed a drop on the exact same date, but the intensity of the drop varied dramatically. I checked our STAT information across desktop inquiries (en-US only)-- over two million daily SERPs-- and saw the following:.
While mobile SERPs in STAT showed higher general frequency, the pattern was extremely comparable, with a 9% day-over-day-drop on February 19 and a total drop of about 12% since February 10. Keep in mind that, while there is considerable overlap, the desktop and mobile information sets may include different search expressions. While the desktop information set is presently about 2.2 M day-to-day SERPs, mobile is closer to 1.7 M.
Note that the MozCast 10K keywords are manipulated (intentionally) toward much shorter, more competitive phrases, whereas STAT consists of much more "long-tail" expressions. This explains the total greater prevalence in STAT, as longer expressions tend to include concerns and other natural-language inquiries that are more likely to drive Featured Snippets.
Why the huge distinction?
What's driving the 40% drop in MozCast and, probably, more competitive terms? Things first: we have actually hand-verified a number of these losses, and there is no proof of measurement mistake. One valuable aspect of the 10K MozCast keywords is that they're equally divided throughout 20 historic Google Advertisements categories. While some modifications effect market classifications likewise, the Featured Bit loss showed a dramatic variety of impact:.


lupus.
autism.fibromyalgia.
acne.While Financing had a much lower preliminary frequency of Included Snippets, Finance SERPs also saw enormous losses on February 19. Some high-volume examples consist of:.
pension.
threat management.shared funds.
roth ira.financial investment.
Like the Health category, these terms have an Understanding Panel in the right-hand column on desktop, with some standard info (primarily from Wikipedia/Wikidata). Again, these are competitive "head" terms, where Google was displaying numerous SERP features prior to February 19.Both Health and Finance search phrases align carefully with so-called YMYL (Your Cash or Your Life) material areas, which, in Google's own words "... might potentially affect an individual's future joy, health, financial stability, or security." These are locations where Google is plainly worried about the quality of the responses they provide.
What about passage indexing?
Could this be tied to the "passage indexing" upgrade that rolled out around February 10? While there's a lot we still don't understand about the impact of that upgrade, and while that update affected rankings and likely affected organic bits of all types, there's no reason to think that update would impact whether or not a Featured Snippet is shown for any provided question. While the timelines overlap a little, these occasions are most likely different.
Is the bit sky falling?
While the 40% https://65d8b6faf3240.site123.me drop in Featured Snippets in MozCast appears to be genuine, the impact was mostly on much shorter, more competitive terms and particular market categories. For those in YMYL classifications, it definitely makes good sense to examine the effect on your rankings and search traffic.
Typically speaking, this is a typical pattern with SERP functions-- Google ramps them up over time, then reaches a limit where quality begins to suffer, and after that lowers the volume. As Google ends up being more confident in the quality of their Featured Bit algorithms, they might turn that volume back up. I certainly don't anticipate Featured Snippets to vanish any time soon, and they're still really prevalent in longer, natural-language questions.
Consider, too, that a few of these Included Bits might just have actually been redundant. Prior to February 19, somebody looking for "mutual fund" might have seen this Included Bit:.
Google is assuming a "What is/are ...?" question here, however "shared fund" is an extremely unclear search that could have numerous intents. At the exact same time, Google was already showing a Knowledge Chart entity in the right-hand column (on desktop), probably from trusted sources:.
Why display both, particularly if Google has issues about quality in a classification where they're extremely sensitive to quality issues? At the exact same time, while it might sting a bit to lose these Featured Bits, consider whether they were actually delivering. While this term may be great for vanity, how often are people at the very beginning of a search journey-- who may not even know what a mutual fund is-- going to transform into a client? In many cases, they may be leaping straight to the Understanding Panel and not even taking the Featured Bit into account.
For Moz Pro consumers, keep in mind that you can easily track Included Bits from the "SERP Features" page (under "Rankings" in the left-hand nav) and filter for keywords with Featured Bits. You'll get a report something like this-- look for the scissors icon to see where Included Bits are appearing and whether you (blue) or a competitor (red) are catching them:.
Whatever the impact, something stays real-- Google giveth and Google taketh away. Unlike losing a ranking or losing an Included Bit to a rival, there's really little you can do to reverse this sort of sweeping change. For websites in heavily-impacted verticals, we can only keep track of the scenario and try to examine our new reality.
Update: Drop by word-count.
I recognized that we might look at word-count in the STAT information to evaluate the theory that much shorter search queries (which are typically both more competitive and more unclear) were struck harder by this update. Here's the breakdown of STAT's 2M desktop (en-US) keywords ...There's not much subtlety here-- 1-word queries were clobbered in this update, 2-word questions dropped considerably higher than the STAT average, and 3+- word queries were hit much less. Why these queries were struck isn't as clear, but the effect on really brief inquiries is clear.
