Featured Snippets Drop
On February 19, MozCast measured a dramatic drop (40% day-over-day) in SERPs with Included Snippets, with no instant 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 always excellent to examine our peace of mind. In this case, other data sets revealed a drop on the same date, however the intensity of the drop differed considerably. So, I checked our STAT data across desktop queries (en-US only)-- over 2 million daily SERPs-- and saw the following:.
While mobile SERPs in STAT revealed greater general frequency, the pattern was extremely similar, with a 9% day-over-day-drop on February 19 and a total drop of about 12% considering that February 10. Note that, while there is significant overlap, the desktop and mobile information sets may contain different search expressions. While the desktop information 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 (deliberately) towards shorter, more competitive phrases, whereas STAT includes many more "long-tail" phrases. This describes the general greater occurrence in STAT, as longer expressions tend to include questions and other natural-language questions 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? First things initially: we have actually hand-verified a variety of these losses, and there is no evidence of measurement mistake. One handy aspect of the 10K MozCast keywords is that they're uniformly divided across 20 historical Google Ads classifications. While some changes impact market classifications similarly, the Featured Snippet loss showed a significant variety of impact:.
Competitive health care terms lost more than two-thirds of their Featured Snippets. It ends up that a number of these terms had other popular features, such as Medical Understanding Panels. Here are some high-volume terms that lost Featured Bits in the Health category:.

lupus.
autism.fibromyalgia.
acne.While Financing had a much lower preliminary prevalence of Featured Snippets, Financing SERPs likewise saw huge losses on February 19. Some high-volume examples include:.
pension.

mutual funds.
roth ira.investment.
Like the Health category, these terms have a Knowledge Panel in the right-hand column on desktop, with some standard information (mainly from Wikipedia/Wikidata). Again, these are competitive "head" terms, where Google was showing several SERP functions prior to February 19.Both Health and Financing search phrases align closely with so-called YMYL (Your Money or Your Life) material areas, which, in http://israelyfau930.raidersfanteamshop.com/what-are-search-engine-optimization-provider-and-also-what-do-search-engine-optimization-firm-services-include Google's own words "... could potentially impact an individual's future happiness, health, monetary stability, or safety." These are areas where Google is clearly worried about the quality of the answers they supply.
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 do not learn about the effect of that upgrade, and while that upgrade impacted rankings and likely affected natural bits of all types, there's no reason to believe that update would impact whether or not an Included Bit is shown for any offered query. While the timelines overlap slightly, these occasions are more than likely different.
Is the bit sky falling?
While the 40% drop in Featured Snippets in MozCast appears to be real, the impact was mainly on shorter, more competitive terms and specific industry categories. For those in YMYL categories, it definitely makes sense to assess the impact on your rankings and search traffic.

Consider, too, that some of these Featured Bits might simply have actually been redundant. Prior to February 19, someone searching for "mutual fund" may have seen this Featured Bit:.
Google is assuming a "What is/are ...?" concern here, but "mutual fund" is a highly uncertain search that might have multiple intents. At the same time, Google was currently revealing an Understanding Chart entity in the right-hand column (on desktop), most likely from relied on sources:.
At the very same time, while it might sting a bit to lose these Featured Bits, think about whether they were actually delivering. In lots of cases, they might be leaping straight to the Knowledge Panel and not even taking the Featured Bit into account.
For Moz Pro clients, bear in mind that you can quickly track Included Bits from the "SERP Features" page (under "Rankings" in the left-hand nav) and filter for keywords with Featured Snippets. You'll get a report something like this-- search for the scissors icon to see where Included Bits are appearing and whether you (blue) or a rival (red) are capturing them:.
Whatever the effect, something remains real-- Google giveth and Google taketh away. Unlike losing a ranking or losing an Included Snippet to a competitor, there's extremely little you can do to reverse this sort of sweeping modification. For websites in heavily-impacted verticals, we can just keep track of the scenario and attempt to assess our brand-new reality.
Update: Come by word-count.
I realized that we might look at word-count in the STAT information to test the theory that shorter search queries (which are usually 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 very little nuance here-- 1-word queries were clobbered in this update, 2-word questions dropped substantially greater than the STAT average, and 3+- word queries were hit much less. Why these queries were hit isn't as clear, however the impact on really short inquiries is clear.
