Included Snippets Drop
On February 19, MozCast measured a significant drop (40% day-over-day) in SERPs with Featured Snippets, without any instant signs of healing. Here's a two-week view (February 10-23):.
Are we losing our minds?
After the year we have actually all had, it's always excellent to inspect our sanity. In this case, other information sets revealed a drop on the same date, however the seriousness of the drop varied drastically. So, I inspected our STAT information throughout desktop inquiries (en-US only)-- over 2 million day-to-day SERPs-- and saw the following:.
While mobile SERPs in STAT showed higher general frequency, the pattern was really similar, with a 9% day-over-day-drop on February 19 and a total drop of about 12% considering that February 10. This explains the overall higher frequency in STAT, as longer expressions tend to include questions and other natural-language inquiries that are more most likely to drive Featured Snippets.
Why the big difference?
What's driving the 40% drop in MozCast and, most likely, more competitive terms? While some changes impact market categories similarly, the Featured Bit loss showed a dramatic variety of impact:.
Competitive health care terms lost more than two-thirds of their Included Snippets. It turns out that much of these terms had other popular functions, such as Medical Knowledge Panels. Here are some high-volume terms that lost Featured Snippets in the Health classification:.
diabetes.
lupus.
autism.
fibromyalgia.
acne.While Finance had a much lower preliminary prevalence of Featured Snippets, Finance SERPs also saw massive losses on February 19. Some high-volume examples include:.
pension.
threat management.mutual funds.
roth ira.investment.
Like the Health category, these terms have a Knowledge Panel in the right-hand column on desktop, with some fundamental information (mostly from Wikipedia/Wikidata). Once 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) content locations, which, in Google's own words "... might possibly impact a person's future joy, health, financial stability, or security." These are locations where Google is plainly concerned about the quality of the responses they provide.
What about passage indexing?
Could this be connected to the "passage indexing" update that presented around February 10? While there's a lot we still do not learn about the effect of that update, and while that upgrade affected rankings and very likely impacted natural bits of all types, there's no reason to think that upgrade would affect whether an Included Snippet is shown for any offered inquiry. While the timelines overlap a little, these events are most likely separate.
Is the bit sky falling?
While the 40% drop in Featured Snippets in MozCast appears to be real, the impact was mainly on much shorter, more competitive terms and specific market categories. For those in YMYL categories, it definitely makes sense to assess the impact on your rankings and search traffic.
Usually speaking, this is a typical pattern with SERP functions-- Google ramps them up over time, then reaches a threshold where quality begins to suffer, and after that lowers the volume. As Google ends up being more positive in the quality of their Included Bit algorithms, they may turn that volume back up. I certainly do not expect Featured Snippets to disappear at any time quickly, and they're still really common in longer, natural-language questions.
Think about, too, that some of these Featured Snippets may just have actually been redundant. Prior to February 19, somebody looking for "mutual fund" may have seen this Featured Bit:.

Google is assuming a "What is/are ...?" question here, however "mutual fund" is an extremely uncertain search that could have numerous intents. At the very same time, Google was already showing a Knowledge Graph entity in the right-hand column (on desktop), probably from relied on sources:.
At the very same time, while it may sting a bit to lose these Included Bits, consider whether they were actually delivering. In numerous cases, they might be leaping straight to the Knowledge Panel and not even taking the Featured Snippet into account.
For Moz Pro clients, remember that you can quickly track Included Snippets from the "SERP Features" page (under "Rankings" in the left-hand nav) and filter for keywords with Included Snippets. You'll get a report something like this-- look for the scissors icon to see where Featured Snippets are appearing and whether you (blue) or a competitor (red) are catching them:.
Whatever the effect, one thing remains true-- Google giveth and Google seo specialist Gold Coast taketh away. Unlike losing a ranking or losing an Included Snippet to a rival, there's extremely little you can do to reverse this kind of sweeping modification. For websites in heavily-impacted verticals, we can only keep an eye on the circumstance and attempt to evaluate our brand-new truth.

Update: Come by word-count.
I understood that we could take a look at word-count in the STAT information to check the theory that shorter search queries (which are usually both more competitive and more ambiguous) were hit harder by this upgrade. Here's the breakdown of STAT's 2M desktop (en-US) keywords ...There's very little subtlety here-- 1-word inquiries were clobbered in this upgrade, 2-word questions dropped considerably greater than the STAT average, and 3+- word questions were struck much less. Why these questions were hit isn't as clear, but the impact on extremely short inquiries is clear.
