Every Second Your Site Feels Slow,
You're Paying More for Every Click.
This isn't a speed issue. It's a revenue leak disguised as performance.
Most sites lose 10–30% of paid traffic value due to interaction delays. Not from bad ads — from slow response.
Fix INP → Lower CPC → Increase Conversions. We fix Interaction to Next Paint at the code level. No ad changes required.
Fixed price. Before/after proof. All major platforms. Measurable improvement guaranteed.
Google Is Actively Penalizing You
Core Web Vitals are a direct Google Ads Quality Score signal. When your site fails INP, Google sees your landing page experience as poor — and charges you accordingly.
Google rates your ad + landing page combination. Poor CWV = lower score.
Lower Quality Score = Google charges you more per click than competitors with faster pages.
Same keyword. Same bid. Slower site = lower ad position, less visibility.
The compounding effect:
Same ad. Same keyword. Faster competitor. They pay less per click, rank higher, and convert more. Every day you wait, the gap widens. We fix the root cause.
You're not just losing conversions. Google is charging you more for the same traffic.
What This Is Costing You Every Month
This isn't theoretical. Based on a conservative 10% paid traffic loss from interaction delays — a number consistent with published research on interaction-to-conversion drop-off.
Our Starter fix is $1,950. It pays for itself in weeks.
Even a modest improvement at $25K/mo spend recovers the cost before the project is done.

User clicks your Google Ad
$18–35 CPC. You just paid.
They land on your page
Looks fine. Loads fast.
They tap "Get a Quote" or "Add to Cart"
Nothing happens for 400–600ms.

Multiplied by every frustrated user, every day.
INP is the invisible leak in your ad funnel. We find it, document it, and eliminate it.
Your Ads Work. Your Pages Don't Respond.
You're paying for every click. But when users tap a button and nothing happens for 400ms, they assume it's broken and bounce — taking your ad dollars with them.
Studies consistently link each second of interaction delay to measurable conversion drops — commonly cited around 7%. ²
Industry surveys show the majority of businesses experience direct revenue loss from poor site responsiveness. ³
Core Web Vitals feed directly into landing page experience — one of Google's three Quality Score components that determines your CPC.
Google evaluates CWV almost exclusively on mobile. Touch interactions are inherently slower than desktop clicks — and the gap matters.

Is This for You?
This is for you if…
- You're running paid search and suspect interaction lag is killing conversion rate
- Your PageSpeed report shows red or orange on INP
- Google Search Console shows "Poor" or "Needs Improvement" on CWV
- You've tried caching plugins and CDNs but INP won't budge
- Your site feels sluggish on mobile — buttons lag, forms hesitate
- You need documented proof of improvement for stakeholders or clients
- You want to reduce CPC by improving your Google Ads Landing Page Experience score
This probably isn't for you if…
- Your INP is already green (≤ 200ms) — you don't need us
- You want a full site redesign, not performance optimization
- Your site is brand new with no real traffic yet
- You're looking for general marketing or SEO content work
- You need hosting migration — that's a separate engagement (see below)
Why this isn't solved by…
- ✗Caching plugins
Cache improves load speed (LCP). INP fires after the page is fully loaded — during the interaction itself. Cached pages can still freeze on tap.
- ✗CDNs
CDNs reduce latency from server to browser. They have no effect on JavaScript execution blocking the main thread after delivery.
- ✗"Speed optimization" agencies
Most optimize load time metrics — LCP, TTFB, total page weight. INP requires profiling JavaScript execution during user interactions specifically. Different discipline.
What we actually do
- →They optimize load speed.
We optimize interaction responsiveness — what happens after the page loads, when your user taps a button and expects something to happen.
- →They reduce file sizes.
We profile JavaScript Long Tasks during real interactions, break them into sub-50ms chunks, and defer non-critical execution using scheduler.yield().
- →They deliver a report.
We deliver code changes, documented before/after data, and a Google Ads Landing Page Experience score that improves — not a PDF with recommendations.
What Is “Interaction to Next Paint”?
INP measures perceived speed — how fast your site visually responds when users click, tap, or type. Your page might load in under 2 seconds (good LCP), but if it feels frozen when a user clicks “Add to Cart” or submits a form, that's a failing INP. Users don't wait.
INP replaced FID (First Input Delay) as a Core Web Vital in March 2024. Google now evaluates responsiveness across every interaction during the full page session — and uses it as a Landing Page Experience signal in Google Ads Quality Score — directly affecting your CPC.
Why INP Fails (And What We Fix)
We specialize in breaking up Long Tasks — any JavaScript execution exceeding 50ms that blocks the main thread. Using production-grade techniques like scheduler.yield() and requestIdleCallback, we defer non-critical code until after user interactions are handled.
Long Tasks > 50ms
Heavy scripts block the main thread during interactions. We break them into sub-50ms chunks using scheduler.yield() and task scheduling.
Third-party script bloat
Chat widgets, pixels, and GTM tags that fire during the first 500ms of interaction. We audit, defer, and remove what's killing responsiveness.
Inefficient event handlers
Click and tap handlers that trigger long processing or excessive DOM mutations. We optimize and debounce expensive operations.
Hydration bottlenecks
React, Next.js, and Vue hydration delays interactivity. We implement selective hydration, lazy loading, and Islands patterns.
Theme & plugin bloat
WordPress page builders and Shopify apps inject blocking JavaScript on every interaction. We defer or replace the worst offenders.
Layout thrashing
Forced synchronous layout during interactions causes expensive reflows. We batch DOM reads/writes and minimize rendering pressure.
We've Seen This Movie Before
These are the root causes we find on nearly every engagement, broken down by platform.
Shopify
- →Judgeme / Loox / Stamped review widgets firing on every interaction
- →Tidio / Gorgias / Zendesk chat loading synchronously
- →Recharge / Bold subscription scripts blocking cart
- →Klaviyo / Attentive popups triggering layout thrash
- →Theme app-blocks with undeferred inline JS
WordPress
- →Elementor / Divi / WPBakery frontend.min.js blocking main thread
- →WooCommerce cart fragments AJAX on every page
- →Contact Form 7 / Gravity Forms loading JS site-wide
- →Slider Revolution / LayerSlider animation loops
- →20+ plugin enqueue conflicts creating > 200ms Long Tasks
Next.js / Headless
- →Full-page hydration blocking interaction until JS bundle executes
- →useEffect chains creating cascading re-renders on mount
- →Client-side state management (Redux/Zustand) triggering unnecessary paints
- →Unoptimized dynamic imports delaying route interaction
- →Analytics/tracking scripts not deferred past hydration

Why INP Fixes Don't Always Stick
The code fix stops the bleeding. Infrastructure is the long-term advantage.
Fixing INP solves the leak.
Code-level remediation delivers immediate, measurable ROI — lower CPC, better conversions, stronger Quality Score. That's what we do, and it works.
But if your infrastructure is still running slow TTFB, plugin-heavy WordPress, or a server not built for today's crawlers, you're fixing symptoms — not the system. New apps and plugins add JS surface area. The ceiling stays low.
Server response time upstream from everything we can fix at the code level.
Infrastructure built without plugin overhead means INP headroom from day one.
LLM crawlers index differently. Infrastructure that accounts for this compounds over time.
INP fix = immediate ROI · Infrastructure = long-term advantage
That's why high-growth teams move to AI Visibility Hosting after the fix.
What Clients Say
“We were spending $40K/mo on Google Ads with a 2.1% conversion rate. After the INP fix, we hit 2.8% without changing a single ad. That's an extra $14K/mo in revenue from the same spend.”
“Two other agencies told us our WordPress site 'couldn't be faster' because of our plugins. Agenxus cut load time by 75% without removing a single one. They optimized the actual code.”
“Our checkout was leaking conversions and we couldn't figure out why — PageSpeed looked fine. Agenxus found three hydration bottlenecks we never would have caught ourselves. INP dropped from 580ms to 160ms in a week.”
“Honestly we had no idea this was even a problem. We thought it was the ads. Spent months testing creatives. It wasn't the ads.”
Common Questions
No. Every change we make is implemented safely and tested before delivery. We work in a staging environment when one is available. For live-only sites, we implement changes in batches with clear documentation of what was modified. Every engagement includes a full rollback plan — a documented list of exactly what to revert if you ever need to. In 5+ years of performance optimization work we've never had a client need to use it, but it's there.
INP measures perceived responsiveness — how quickly your site visually responds when users click, tap, or type. It replaced FID (First Input Delay) as a Core Web Vital in March 2024. Unlike FID which only measured the first interaction, INP evaluates every interaction throughout the page session. A good INP is 200ms or less.
Landing page experience is one of three components of Google Ads Quality Score. Core Web Vitals — including INP — are a signal Google uses to evaluate that Landing Page Experience (LPE) score. A poor LPE rating means lower Quality Score, which translates directly to higher CPC and worse ad placement. You're paying more per click than competitors with faster, more responsive pages.
Load speed (LCP) and interaction speed (INP) are different metrics. Your page can load in under 2 seconds but still feel frozen when users interact. JavaScript blocking the main thread during interactions causes this — even if it loaded fine initially. That's the 'frozen button' problem we fix.
We optimize INP across Shopify, WordPress, Webflow, Wix, Squarespace, Next.js/React, Nuxt/Vue, Shopify Hydrogen, and custom stacks. Each platform has specific bottlenecks and we know the root causes on each.
A Long Task is any JavaScript execution exceeding 50ms that blocks the browser's main thread. During a Long Task, the browser can't respond to user interactions. We use techniques like scheduler.yield() and requestIdleCallback to break long tasks into sub-50ms chunks.
Code changes via PR or direct commit, before/after RUM and lab data, a Long Task inventory with script deferral map, exact files changed with optimization summary, a third-party script audit report, and a rollback plan. Everything is documented.
At checkout you complete a questionnaire about your platform, issues, and goals. Within 24 hours we confirm scope and request secure access. We implement optimizations and deliver documented before/after evidence.
Yes. We guarantee measurable INP improvement. If we can't improve your score, we keep working until we do — or refund the audit fee. We target ≤ 200ms. In rare cases where platform limitations prevent reaching 200ms, we document what was achieved and recommend next steps.
