Featured Snippets Drop
On February 19, MozCast determined a significant drop (40% day-over-day) in SERPs with Featured Bits, with no immediate indications 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 constantly good to inspect our peace of mind. In this case, other data sets showed a drop on the same date, but the severity of the drop varied dramatically. I inspected our STAT data across desktop questions (en-US only)-- over two million day-to-day SERPs-- and saw the following:.
While mobile SERPs in STAT showed higher total occurrence, the pattern was very comparable, with a 9% day-over-day-drop on February 19 and a total drop of about 12% given that February 10. Note that, while there is substantial overlap, the desktop and mobile information sets may contain various search expressions. While the desktop data set is currently about 2.2 M day-to-day SERPs, mobile is closer to 1.7 M.
Note that the MozCast 10K keywords are skewed (intentionally) towards shorter, more competitive phrases, whereas STAT consists of a lot more "long-tail" phrases. This explains the general higher frequency in STAT, as longer phrases tend to consist of concerns and other natural-language inquiries that are most likely to drive Featured Snippets.
Why the big difference?
What's driving the 40% drop in MozCast and, presumably, more competitive terms? While some modifications impact industry classifications likewise, the Featured Bit loss showed a dramatic variety of impact:.
Competitive healthcare terms lost more than two-thirds of their Featured Snippets. It ends up that a number 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 category:.

lupus.
autism.fibromyalgia.
acne.While Financing had a much lower preliminary prevalence of Included Snippets, Finance SERPs also saw enormous losses on February 19. Some high-volume examples consist of:.
pension.
danger management.mutual funds.
roth ira.investment.
Like the Health classification, these terms have a Knowledge Panel in the right-hand column on desktop, with some fundamental details (mainly from Wikipedia/Wikidata). Once again, these are competitive "head" terms, where Google was displaying numerous SERP features prior to February 19.
Both Health and Financing search expressions line up carefully with so-called YMYL (Your Cash or Your Life) content locations, which, in Google's own words "... might possibly impact an individual's future happiness, health, monetary stability, or security." These are locations where Google is plainly concerned about the quality of the answers they provide.

What about passage indexing?
Could this be connected to the "passage indexing" upgrade that presented around February 10? While there's a lot we still do not understand about the impact of that update, and while that upgrade affected rankings and highly likely affected natural bits of all types, there's no reason to think that upgrade would impact whether or not an Included Snippet is shown for any offered question. While the timelines overlap a little, these occasions are probably separate.
Is the snippet sky falling?
While the 40% drop in Featured Snippets in MozCast seems genuine, the impact was primarily on shorter, more competitive terms and particular industry classifications. For those in YMYL categories, it definitely makes good sense to assess the influence on your rankings and search traffic.
Typically speaking, this is a common pattern with SERP functions-- Google ramps them up with time, then reaches a threshold where quality starts to suffer, and then reduces the volume. As Google ends up being more positive in the quality of their Featured Bit algorithms, they may turn that volume back up. I certainly don't anticipate Featured Snippets to disappear any time soon, and they're still very common in longer, natural-language questions.

Google is presuming a "What is/are ...?" concern here, but "mutual fund" is an extremely unclear search that could have multiple intents. At the exact same time, Google was currently revealing a Knowledge Graph entity in the right-hand column (on desktop), presumably from relied on sources:.
Why display both, specifically if Google has issues about quality in a classification where they're very sensitive to quality problems? At the exact same time, while it may sting a bit to lose these Featured Snippets, consider whether they were really providing. While this term may be great for vanity, how typically are people at the very beginning of a search journey-- who may not even understand what a mutual fund is-- going to convert into a customer? Oftentimes, they might be jumping straight to the Understanding Panel and not even taking the Included Snippet into account.
For Moz Pro customers, 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 Featured Bits. You'll get a report something like this-- search for the scissors icon to see where Included Snippets are appearing and whether you (blue) or a competitor (red) are seo services gold coast capturing them:.
Whatever the impact, one thing stays real-- Google giveth and Google taketh away. Unlike losing a ranking or losing an Included Snippet to a competitor, there's very little you can do to reverse this kind of sweeping modification. For sites in heavily-impacted verticals, we can just keep track of the circumstance and attempt to evaluate our brand-new reality.
Update: Stop by word-count.
I understood that we could take a look at word-count in the STAT data to evaluate the theory that much shorter search questions (which are normally both more competitive and more ambiguous) were struck harder by this update. Here's the breakdown of STAT's 2M desktop (en-US) keywords ...There's not much nuance here-- 1-word queries were clobbered in this upgrade, 2-word questions dropped considerably greater than the STAT average, and 3+- word queries were hit much less. Why these questions were hit isn't as clear, however the effect on extremely brief queries is clear.
