Included Snippets Drop
On February 19, MozCast measured a significant drop (40% day-over-day) in SERPs with Included Bits, with no 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 constantly excellent to check our sanity. In this case, other data sets revealed a drop on the same date, however the intensity of the drop varied considerably. I checked our STAT information throughout desktop questions (en-US just)-- over 2 million day-to-day SERPs-- and saw the following:.
While mobile SERPs in STAT revealed higher total occurrence, the pattern was extremely similar, with a 9% day-over-day-drop on February 19 and an overall drop of about 12% since February 10. This discusses the general greater prevalence in STAT, as longer phrases tend to include questions and other natural-language inquiries that are more likely to drive Featured Snippets.
Why the big difference?
What's driving the 40% drop in MozCast and, probably, more competitive terms? First things initially: we've hand-verified a variety of these losses, and there is no evidence of measurement error. One valuable element of the 10K MozCast keywords is that they're equally divided across 20 historical Google Ads classifications. While some changes impact industry classifications similarly, the Featured Snippet loss showed a significant variety of impact:.
Competitive health care terms lost more than two-thirds of their Included Snippets. It turns out that many of these terms had other popular functions, such as Medical Understanding Panels. Here are some high-volume terms that lost Included Bits in the Health category:.

lupus.
autism.fibromyalgia.
acne.While Financing had a much lower initial prevalence of Featured Bits, Finance SERPs also saw huge losses on February 19. Some high-volume examples consist of:.
pension.
risk management.mutual funds.
roth ira.financial investment.
Like the Health category, these terms have an Understanding Panel in the right-hand column on desktop, with some basic information (mostly from Wikipedia/Wikidata). Once again, these are competitive "head" terms, where Google was displaying several SERP features prior to February 19.

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 don't understand about the impact of that update, and while that upgrade affected rankings seo specialist Gold Coast and very likely affected organic bits of all types, there's no reason to think that update would affect whether a Featured Snippet is displayed for any provided query. While the timelines overlap a little, these occasions are probably different.
Is the snippet sky falling?
While the 40% drop in Featured Snippets in MozCast seems genuine, the effect was mainly on shorter, more competitive terms and particular market classifications. For those in YMYL classifications, it definitely makes sense to assess the influence on your rankings and search traffic.
Generally 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 positive in the quality of their Featured Snippet algorithms, they might turn that volume back up. I definitely do not expect Featured Bits to vanish at any time quickly, and they're still very prevalent in longer, natural-language inquiries.
Think about, too, that some of these Featured Snippets may just have been redundant. Prior to February 19, somebody looking for "mutual fund" might have seen this Included Snippet:.
Google is assuming a "What is/are ...?" concern here, however "shared fund" is a highly uncertain search that could have numerous intents. At the exact same time, Google was already revealing an Understanding Graph entity in the right-hand column (on desktop), probably from relied on sources:.

For Moz Pro clients, bear in mind that you can easily track Included Bits from the "SERP Functions" page (under "Rankings" in the left-hand nav) and filter for keywords with Featured Snippets. You'll get a report something like this-- try to find the scissors icon to see where Featured Bits are appearing and whether you (blue) or a rival (red) are capturing them:.
Whatever the impact, one thing remains real-- Google giveth and Google taketh away. Unlike losing a ranking or losing an Included Bit to a competitor, there's very little you can do to reverse this sort of sweeping modification. For websites in heavily-impacted verticals, we can only keep an eye on the circumstance and try to assess our new reality.
Update: Visit word-count.
I realized that we might take a look at word-count in the STAT data to check the theory that shorter search queries (which are typically both more competitive and more uncertain) 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 inquiries were clobbered in this upgrade, 2-word questions dropped significantly greater than the STAT average, and 3+- word inquiries were hit much less. Why these inquiries were struck isn't as clear, but the effect on really brief questions is clear.
