What Is the February 2026 Google Discover Core Update?

What Google Says the Update Changes

Google published official guidance alongside the update that made its priorities clear. The February 2026 Discover Core Update is designed to do three things:

• Show users more locally relevant content from websites based in their own country
• Reduce sensational content and clickbait appearing in Discover
• Elevate in-depth, original, and timely content from websites with demonstrated expertise in a given subject area

The local relevance piece has an immediate practical implication: non-US websites that have been publishing content aimed at US audiences may see Discover traffic drop in the United States. Google acknowledged this directly, noting that while those sites may lose US Discover exposure, they should see gains in their own local markets over time as the update expands globally.

The expertise angle is equally significant. Google’s John Mueller clarified that the system is designed to identify expertise on a topic-by-topic basis rather than evaluating a site as an expert in everything or nothing. A local news outlet with a dedicated health section, for example, could demonstrate expertise in health topics even if the site covers other subjects. A dental practice blog that publishes consistent, substantive content about oral health is exactly the kind of site this framing is designed to reward.

Conversely, a site that occasionally publishes content outside its lane on topics where it has no track record is unlikely to benefit.

What Google Updated in Its Discover Documentation

Alongside the update announcement, Google revised its official Discover documentation to spell out what it now expects from content surfaced in the feed. The updated guidance tells publishers to:

• Avoid clickbait and tactics that artificially inflate engagement through misleading or exaggerated previews
• Use page titles and headlines that accurately capture what the content is actually about
• Avoid sensationalism designed to trigger morbid curiosity, outrage, or titillation
• Provide content that is timely, tells a story well, or offers unique insight
• Include high-quality images at least 1,200 pixels wide to improve Discover performance
• Deliver an overall strong page experience, including avoiding intrusive ads, auto-playing media, and other elements that degrade the user experience

That last point is worth noting for dental practices specifically. Page experience has become a meaningful ranking signal across Google’s systems, and Discover is now explicitly part of that conversation. A website that loads slowly, pushes aggressive popups, or delivers a poor mobile experience is at risk on multiple fronts simultaneously.

The Community Response: Significant Impact Across the Board

The SEO and publisher community noticed the Discover update immediately, and the reaction has been intense. Reports from webmasters and publishers began flooding forums within days of the February 5 launch.

Some publishers described losing nearly all Discover-driven traffic overnight. Others reported being removed from both Discover and Google News simultaneously. A smaller number noted that content which had previously disappeared from Discover began showing up again once the update was underway, suggesting the system was actively recalibrating.

The range of experiences reflects what Google has consistently said about core updates. Some sites will see significant traffic losses, some will see gains, and many will see little change at all. What makes this update unusual is its narrow scope. Because it targeted Discover specifically rather than general search rankings, sites could find themselves unaffected in organic search while experiencing major shifts in their Discover traffic, or vice versa.

The Update Is Over. The Volatility Is Not.

Here is where things stand as of early March 2026: the February Discover Core Update officially wrapped up on February 27. But Google search ranking volatility has not followed suit.

Tracking tools used by the SEO industry, including Semrush, Mozcast, Sistrix, Accuranker, and others, have continued to show elevated volatility readings well into March. Some tools have registered scores approaching the high end of their volatility scales, levels that typically indicate significant, widespread ranking movement.

Webmasters and SEOs reporting on industry forums have described conditions that do not feel like post-update stabilization. Traffic drops of 20% or more have been reported in the days following the official end date. Rankings for specific keywords have been observed shifting multiple times within a single day. Some participants in industry discussions have speculated that an additional, unannounced update, possibly a smaller core update, may already be rolling out.

Google has not confirmed the cause of ongoing post-update volatility, which is consistent with its handling of what industry observers have termed “smaller core updates”: algorithm refinements that happen continuously and that Google typically declines to acknowledge or comment on individually.

The practical reality for dental website owners is that the search landscape has been in a state of near-constant adjustment since at least late 2025, with volatility spikes reported in December, January, and throughout February. The completion of the Discover Core Update has not brought the settled conditions that typically follow a major announced update.

What This Means for Dental Practices

For dental practices and small healthcare businesses, there are a few takeaways worth acting on.

Discover is now an expertise-driven channel. If your practice website publishes original, in-depth content about dental topics on a consistent basis, your content is better positioned to surface in Discover than it was before this update. Thin content, repurposed articles, and clickbait-style headlines are now explicit targets for demotion. A practice blog that genuinely helps patients understand their treatment options is the kind of content Google says it wants to elevate.

Page experience matters more than ever. Google’s updated Discover documentation added page experience as an explicit factor. Practices should ensure their websites load quickly, work well on mobile devices, and avoid intrusive elements. My Social Practice’s dental website design service builds sites with these technical foundations built in, which becomes increasingly important as Google tightens its standards.

Organic search and Discover are now somewhat separate conversations. A site can hold strong organic rankings while losing Discover traffic, or gain in Discover while seeing no movement in traditional search results. Tracking both separately is now more important than it used to be.

Volatility is not a reason to panic, but it is a reason to pay attention. Extended periods of algorithm instability like the one currently underway can create misleading traffic signals. A traffic drop that looks alarming in isolation may be temporary volatility rather than a lasting penalty. Practices should look at trends over weeks and months, not days, and focus on the fundamentals, like strong content, clean site architecture, good page experience, and consistent local SEO signals. My Social Practice’s dental SEO services are built around exactly those long-term fundamentals, which tend to hold up better through algorithm turbulence than tactics chasing short-term ranking gains.

Discover Core Update: The Bottom Line

The February 2026 Google Discover Core Update is the clearest signal yet that Google is actively reshaping how Discover surfaces content, moving decisively toward expertise, relevance, and quality while reducing the reach of clickbait and sensationalism. The fact that ranking volatility has continued even after the update’s official completion suggests the broader algorithm environment remains unsettled, and that more adjustments are likely coming.

For dental practices, the path through this kind of volatility looks the same as it always has. The best course is to publish content that genuinely serves patients, maintain a fast and well-structured website, and build the kind of consistent online presence that algorithms are increasingly designed to reward. The practices doing that work now will be better positioned when the dust finally settles.
