What "Position Zero" Actually Is
A featured snippet is a boxed answer that Google extracts from a web page and displays above the standard organic listings. Because it sits ahead of the first conventional result, practitioners began calling it "position zero." The label is convenient but slightly misleading: the snippet is not a separate placement above the index. The page that fills the snippet box is pulled from the organic results for that query, almost always from a page already ranking on the first page.
This origin matters for understanding the click-through-rate debate. Because the snippet is drawn from the same ranking system that orders the ten blue links, the systems that determine organic position also determine, in large part, which page becomes eligible to fill the snippet. Google's click-based re-ranking layer is central to that ordering. For the foundational explanation of how this works, see What is NavBoost?
The core tension is this: a featured snippet answers part or all of a query directly on the results page. For the page that owns the snippet, that prominence can mean an outsized share of clicks. For every other page on the SERP, including pages that rank highly in the standard listings beneath the box, the snippet can absorb attention and depress clicks. Whether the snippet "helps" or "hurts" therefore depends entirely on perspective and on whether the box is yours.
The Snippet CTR Data: Winner and Bystanders
The clearest numbers on featured snippet click behavior come from SISTRIX, which segmented click-through rates by the type of element present on the results page. Two figures from that analysis frame the entire debate.
First, the page that occupies the featured snippet earns a click-through rate of approximately 42.9% on the queries where it holds the box. That is higher than the click-through rate for a pure-organic position-one result, which SISTRIX places around 34.2% (and which First Page Sage's 2026 data puts as high as 39.8% for a clean organic SERP). In other words, owning the snippet can win a larger share of clicks than ranking first on a results page that has no snippet at all.
Second, and pulling in the opposite direction: when a featured snippet is present, the standard position-one result beneath it sees its CTR fall to roughly 23.3%. SISTRIX found that the presence of a snippet pushes the first conventional position to about 5.3 percentage points below its average value. The snippet, in effect, reaches up and takes a slice of the clicks that the first organic listing would otherwise capture.
| SERP scenario | Position-1 CTR | What it means |
|---|---|---|
| Pure organic (no features) | ~34.2% | Baseline for a clean ten-blue-links SERP (SISTRIX) |
| You own the featured snippet | ~42.9% | The snippet itself captures the largest share of clicks |
| Snippet present, you rank #1 below it | ~23.3% | The box absorbs clicks the #1 result would have earned |
| Snippet present, you rank #2 below it | ~15.7-20.5% | SISTRIX found positions 2-3 can gain relative to average |
The third figure in that table is the subtle one. SISTRIX found that while the snippet suppresses the first standard position, results in positions two and three can actually gain clicks relative to their average when a snippet is present, with the second position rising from roughly 15.7% to as high as 20.5%. The interpretation: users who read the snippet, find it insufficient, and decide to investigate further tend to skip the answer box and scan the conventional results immediately below it. A page ranking just outside the snippet can sometimes benefit from the snippet's failure to fully satisfy the searcher.
The asymmetry in one sentence
Holding the featured snippet is the single most valuable organic placement on a results page that has one (~42.9% CTR), but ranking #1 beneath someone else's snippet is worse than ranking #1 on a page with no snippet at all (~23.3% versus ~34.2%).

When Owning the Snippet Wins Clicks — and When It Cannibalizes Them
The 42.9% figure is an average across all featured snippet queries. It conceals wide variation, because not every snippet behaves the same way. The decisive variable is whether the snippet answers the query completely or merely partially.
Snippets that win clicks
For queries where the snippet whets the user's appetite without fully satisfying it, owning the box tends to win clicks. These are typically queries where the searcher needs context, steps, nuance, or a source they can trust. A snippet that shows the first three steps of a ten-step process, or defines a term the reader then wants to explore, gives the user a reason to click through. In these cases the snippet functions as an enlarged, more prominent organic listing, and its elevated visibility converts into the higher click share that the 42.9% average reflects.
Snippets that cannibalize clicks
For queries that the snippet answers completely, owning the box can be a hollow victory. If a user searches for a single fact — a conversion rate, a date, a definition, a short answer — and the snippet displays exactly that fact, the user has no reason to click. The snippet satisfies the query on the results page and the search ends without a visit. This is the mechanism behind zero-click searches, and featured snippets are one of the SERP features that drive it.
The distinction is the same one that governs every featured snippet decision: a snippet that prompts further investigation passes traffic to its source; a snippet that resolves the query keeps the user on Google. The page may "rank" at position zero in both cases, but only one of them produces a visit.
A practical test before chasing a snippet: whether the target query can be fully answered in the 40-60 words a snippet displays. If it can, winning the snippet may simply hand Google a no-click answer drawn from the source page. If the honest answer requires more — steps, judgment, depth, or trust — the snippet is more likely to earn the click.
How Glue Assembles the Snippet
The featured snippet does not appear by accident, and its source is not chosen by content relevance alone. The 2024 Google API leak and the antitrust trial testimony together pointed to a system commonly referred to as Glue, which extends the logic of click-based re-ranking from the standard organic results to the broader set of SERP features.
Where the click re-ranking layer orders the ten blue links, Glue is described in the leak analysis as operating across the full results page — not just the conventional listings, but Knowledge Panels, video carousels, image packs, People Also Ask boxes, and the featured snippet itself. According to the RESONEO breakdown of the leaked documentation, Glue functions as a kind of expanded query log that aggregates user interactions with the entire SERP, including clicks, hovers, scrolls, and dwell time on the results page, to decide which features should appear for a query and which source should fill them. For the dedicated treatment of this system, see Glue: Ranking Universal Search Results with Click Signals.
The implication for featured snippets is direct. Two separate questions are being answered by interaction data:
- Should a featured snippet appear at all for this query? Glue weighs whether users have historically engaged with a snippet-style answer for queries of this shape, or whether they tend to scan the full list instead.
- Which page should supply the snippet? The eligible candidates are drawn from the organic results, which the click re-ranking layer has already ordered. A page that earns strong satisfaction signals — the kind of dwell-time behavior that marks a result as genuinely useful — is more likely to be both ranking highly and selected for the box.
This means click behavior shapes the snippet on two levels: it determines the organic ordering from which the snippet source is drawn, and it informs Glue's decision about whether and how to present the feature. The featured snippet is best understood not as a separate prize but as one output of the same user-interaction machinery that orders the rest of the page.
"Glue is essentially NavBoost expanded to cover all SERP features, not just the ten blue links, but also Knowledge Panels, video carousels, image packs, People Also Ask boxes, and AI Overviews."

The 2025-2026 Shift: AI Overviews Subsume the Snippet
The featured snippet debate changed character in 2025. The format that practitioners had spent years optimizing for began to disappear from results pages, displaced by AI Overviews that occupy the same prime real estate at the top of the SERP and serve the same fundamental purpose: answering the query without a click.
SERP-tracking studies documented the shift in detail. Featured snippet coverage fell from roughly 15% of results pages in early 2025 to about 5.5% by mid-2025 — a relative decline of roughly two-thirds in six months. Over the same period, AI Overview coverage climbed steeply, with one analysis of more than a million US desktop results finding a strong negative correlation (reported around −0.90) between the presence of a featured snippet and the presence of an AI Overview. As one grew, the other shrank. The two features rarely co-occur; some research found them appearing together on only around 7% of searches.
The substitution is not cosmetic, because the two features cannibalize clicks very differently. A traditional featured snippet, drawn from a single source, still passes meaningful traffic to that source — it functions as an enlarged single-source listing. An AI Overview, which synthesizes an answer from multiple sources, appears to pass considerably less to any one of them, though published estimates of the citation click-through rate vary widely and remain disputed. Ahrefs found that the presence of an AI Overview reduced clicks to the top organic result by approximately 58%, and Semrush data indicates that around 83% of searches with an AI Overview present end without any click. The trend toward zero-click searches — already at 58.5% of US searches per Semrush's 2025 data and projected to climb further — is accelerated, not caused, by this transition.
| Metric | Featured snippet | AI Overview |
|---|---|---|
| Sources used | Single page | Multiple pages, synthesized |
| Click-through to source | Meaningful (single source) | Much lower; estimates disputed |
| Zero-click rate on the query | Moderate | ~83% |
| SERP coverage, mid-2025 | ~5.5% | Rising past ~27% |
For the full analysis of how generative results reshaped the click curve, see How AI Overviews Changed CTR. The practical takeaway for featured snippet strategy is that the snippet is now a shrinking and partly transitional format: on many informational queries, the question of whether to optimize for a snippet has been overtaken by the question of whether the query still produces a clickable result at all.
Practical Guidance: Optimize For, or Deliberately Avoid?
Given the data, a featured snippet is neither universally worth pursuing nor universally worth avoiding. The decision turns on query intent, answer depth, and whether prominence converts into engagement. The following framework summarizes when each posture makes sense.
| Situation | Recommended posture | Why |
|---|---|---|
| Query needs depth, steps, or trust; snippet is a teaser | Optimize for it | ~42.9% CTR; snippet drives the click rather than ending the search |
| Query is a single fact fully answered in 40-60 words | Reconsider | Risk of supplying a no-click answer; little onward traffic |
| Competitor owns the snippet; you rank #2-#3 | Hold position | Positions 2-3 can gain CTR when the snippet under-satisfies |
| Query now triggers an AI Overview | Shift focus | Snippet largely displaced; optimize for citation and brand recall |
| Branded or navigational query | Win the snippet | Intent is high; the click usually still happens regardless |
The role of genuine engagement
Whichever posture a site adopts, the underlying mechanism rewards the same thing: results that users find satisfying. Because click re-ranking and Glue both feed on real user interaction, the durable way to influence both organic position and snippet eligibility is to produce pages that earn genuine dwell time and discourage pogo-sticking — the quick return to the SERP that marks a result as unsatisfying. A page that captures the snippet but generates pogo-sticking when users do click through sends mixed signals; a page that satisfies the intent behind the query reinforces its standing.
This is one reason the click signals that feed these systems resist artificial manipulation. The interaction data is aggregated over a long window, normalized to compress outliers, and cross-checked against other quality signals. Some services attempt to influence click signals directly — SerpClix, for example, operates a crowd-sourced network of real human clickers rather than automated bots — but Google's artificial-click detection systems and the structural defenses of the re-ranking layer mean that any click signal, organic or otherwise, ultimately has to be matched by genuine on-page satisfaction to hold. For featured snippets specifically, the lesson is that winning the box is only durable when the underlying page actually answers the query users came to resolve.
Measuring Snippet Impact in Your Own Data
Because the same snippet can win or lose clicks depending on the query, aggregate benchmarks like 42.9% are starting points, not verdicts. The reliable way to know whether a featured snippet helps a specific page is to measure it directly. Three observations from the data above translate into measurable signals:
- Compare clicks against impressions for snippet queries. If a query gains the snippet and impressions hold steady while clicks fall, the snippet is likely cannibalizing rather than capturing — the fully-answered-query pattern.
- Watch for the position-2 lift. If a competitor holds the snippet and a page ranks just below it, the SISTRIX data suggests the page may earn more clicks than its raw position implies. Losing the snippet race is not always losing the click race.
- Track snippet-to-AI-Overview transitions. When a query that once showed a featured snippet begins showing an AI Overview instead, expect a step-change drop in click-through and reassess whether the query is still worth optimizing for clicks at all.
The featured snippet, in the end, is a microcosm of the broader click-signal story: prominence on the results page is valuable only insofar as it converts into a satisfied visit, and Google's systems are increasingly engineered to reward genuine satisfaction over mere visibility.

Frequently Asked Questions
Do featured snippets increase or decrease click-through rate?
It depends on whether the snippet box is yours. According to SISTRIX, a featured snippet captures roughly 42.9% of clicks for the result that occupies it, which is higher than a pure-organic position-one CTR of about 34.2% to 39.8%. But when a featured snippet appears and a result sits in the standard position-one slot beneath it, that position-one CTR falls to about 23.3%. Owning the snippet can win clicks; ranking just below one usually loses them. See CTR by position for the full curve.
What is position zero in Google search?
Position zero is the informal name for the featured snippet, a boxed answer Google extracts from a web page and displays above the standard organic results. It is called position zero because it appears before the first conventional listing. The result that supplies the snippet is pulled from the organic index, so position zero and the ten blue links are drawn from the same ranking system rather than being separate placements.
Are featured snippets causing zero-click searches?
Featured snippets contribute to zero-click behavior because they answer some queries directly on the results page, but their effect is far milder than AI Overviews. Ahrefs found that AI Overviews reduce clicks to the top organic result by about 58%, and Semrush data shows around 83% of searches with an AI Overview end without a click. A traditional featured snippet still passes meaningful traffic to its source, especially for queries where users need more than a one-sentence answer.
Are featured snippets disappearing?
Featured snippet prevalence dropped sharply in 2025 as AI Overviews expanded. Multiple SERP-tracking studies found featured snippet coverage falling from roughly 15% of results in early 2025 to about 5.5% by mid-2025, with researchers reporting a strong negative correlation between featured snippet and AI Overview appearance. The snippet format has not been retired, but Google increasingly substitutes a multi-source AI Overview for the single-source snippet on informational queries.
How does NavBoost relate to featured snippets?
NavBoost re-ranks the standard organic results based on click behavior, and the page that earns the featured snippet is typically drawn from those re-ranked results. A related system called Glue extends the same click-and-interaction logic to SERP features, deciding which features appear and which source fills them. So click signals influence both the ordering of organic results and the assembly of the snippet box above them.
Should you optimize for a featured snippet or avoid one?
For informational queries where users want a quick fact and you can capture the snippet, optimizing for it can win the largest share of available clicks. For queries where the snippet fully answers the question without your brand benefiting, or where a competitor holds the box and you rank just below it, the snippet can suppress your clicks. The decision depends on query intent, whether the answer requires depth, and whether owning position zero translates into onward engagement rather than a satisfied departure.
