Pages that AI cites most record a good INP on 87% of loads, vs 89% for least-cited pages — a modest, correlational edge on top of an already-healthy baseline.
Interaction to Next Paint (INP) measures how quickly a page responds to input. A page “passes” INP when it responds to interactions within 200 ms for most real users, as measured by Google’s Chrome UX Report (CrUX) field data. This report joins that field data to AmICited’s citation tracking to ask a simple question: are the pages AI engines cite more often any better on INP?
Across all cited domains with field data, 88% record a good INP — a solid baseline. But the most-cited domains do a little better still: 87% of the pages cited 10+ times hit the good threshold, versus 89% of those cited only once or twice.
Good INP rate vs citation frequency
The direction matches every other Core Web Vitals signal in this dataset: pages AI cites more often are modestly more likely to clear Google’s good-INP bar. The gap here is 2 percentage points between the most- and least-cited groups — real and consistent, but small. It says INP is a supporting signal, not a gatekeeper: plenty of frequently-cited pages have imperfect INP, and plenty of technically excellent pages are barely cited.
The underlying numbers
| Citation frequency | Domains w/ data | Good INP |
|---|---|---|
| Cited 10+ times | 659 | 87% |
| Cited 3–9 times | 1,584 | 88% |
| Cited 1–2 times | 4,313 | 89% |

How INP compares to the other Core Web Vitals
Among the cited pages, the vitals are not equally easy to pass. Across the full cited set, INP is the strongest (88% good) and FCP the weakest (75% good), with INP at 88%. That ordering is itself useful: if you are triaging fixes on your own site, the metric the AI-cited set most often fails is usually where the easiest competitive gap lies — the bar there is lower for everyone.
What this means for AI-search visibility
The practical takeaway is the same as for Core Web Vitals overall: fixing INP is worth doing, but it is table stakes, not a growth lever for AI citations. It removes a mild disadvantage and — more importantly — improves the real-user experience for the traffic you already have. But on this evidence, a great INP score will not by itself move you into an engine’s cited set; content relevance and being present in the sources these engines synthesize matter far more. Sequence it accordingly: get INP into the “good” band as hygiene, then put the bulk of your effort into relevance and coverage.

Why INP matters for AI search visibility
Interaction to Next Paint measures how quickly a page responds to user input — clicks, taps, and keyboard presses. Of all the Core Web Vitals, INP is the one most purely about the human experience. AI crawlers do not click buttons, fill forms, or interact with UI elements; they parse static HTML . So it should not be surprising that INP shows no positive correlation with citation frequency.
In fact, the data shows a slight inverse relationship: the most-cited pages pass INP at 87%, while the least-cited pass at 89%. This is almost certainly noise rather than a real signal, but it reinforces the broader finding: AI engines are not using interactivity as a ranking or selection factor. A page with excellent INP is no more likely to be cited than one with poor INP.
That said, INP still matters for the downstream value of AI citations. If a user clicks through from an AI answer and lands on a page that feels sluggish and unresponsive, they are likely to leave quickly. INP directly affects the quality of the traffic you receive from AI search — even if it does not affect how much traffic you receive.
How AI-cited pages compare to the broader web
INP is the newest and most challenging Core Web Vital. Google’s CrUX data shows that only about 60–65% of URLs across the web achieve a “good” INP score. The AI-cited set at 88% is significantly above the web average — one of the widest gaps among the three vitals.
This makes sense: the pages AI engines cite come disproportionately from well-funded, technically mature sites that have had the engineering resources to address the interactivity challenges INP measures. Smaller sites, blogs, and forums — which make up a large portion of the web — are far more likely to struggle with INP. The 88% pass rate in the cited set is a reflection of the kind of sites that earn AI citations, not evidence that INP drives citations.
Practical recommendations
INP is the hardest Core Web Vital to fix, but also the one with the least citation benefit. Prioritize accordingly:
Audit your interactivity with the Chrome DevTools Performance panel. Identify long tasks that block the main thread — these are the root cause of poor INP. Common culprits are heavy JavaScript bundles, unoptimized third-party scripts, and expensive event handlers.
Break up long tasks. The most effective INP fix is to split large JavaScript tasks into smaller, asynchronous chunks. This lets the browser handle user input between chunks rather than queuing it.
Defer non-critical JavaScript. Move analytics, chat widgets, and other third-party scripts to load after the main content. Use
asyncordeferattributes, or load them programmatically after the page is interactive.Be realistic about ROI for AI visibility . Given the zero (or slightly negative) correlation with citation frequency, INP should be the lowest priority of the Core Web Vitals for AI-visibility purposes. Fix it if users are complaining about sluggishness; otherwise, invest your time in content and relevance.
Methodology
INP “good” fractions come from Google CrUX field data joined to AmICited’s citation tracking across 1,905 tracked prompts (June 24, 2026 – July 23, 2026, 2026). CrUX data was available for 6,556 of 8,845 cited domains (74%) — pages too low-traffic for CrUX are excluded, which slightly biases the sample toward more-visited sites. Domains are grouped by how many tracked-prompt responses cited them; the good-INP fraction is averaged within each group, and the overall/comparison figures are volume-weighted across groups. This is an association among cited pages, not proven causation — we are not claiming a better INP causes more citations. No external links appear in this report.
