One interactive home base for spotting anomalies in Shopify traffic. Each chart overlays total sessions (blue) with the zero-second / instant-bounce portion (amber) and the conversion rate that results (green). Hover any chart for the exact weekly numbers; click a legend label to isolate a line. Weekly, last two years. Every sessions series reconciles to Shopify's reported totals.

All sessions — total vs zero-second, with conversion rate
Blue = total sessions · amber = zero-second portion · green = conversion rate (right axis). Hover for weekly detail.
Zero-second share over time
The % of all sessions that bounce instantly. A bot/fraud event would spike this line; instead it sits in a tight band.
Conversion rate over time
Mirror image of quality: as zero-second share crept up and the traffic mix shifted, blended CVR drifted from ~2.5% to ~1.8%.
02 · By referral channel
Zero-second share by channel
If a competitor flooded one channel with bots, its line would break upward away from the pack. Click a label to isolate it.
Stable bands for two years: YouTube ~80%, Facebook/Instagram/Direct ~73%, Google ~57%. No channel shows an attack-style step-change.
Conversion rate by channel
Google (search) leads ~4%. Facebook CVR cratered to ~0.7% in Sep–Oct 2025 then recovered; Instagram is sliding toward ~0.6% now.
"Direct" (9.7M) absorbs untagged + in-app-browser traffic, so its volume is inflated. TikTok excluded — referral collapsed to ~zero after Nov 2025.
03 · By landing page
Zero-second share by landing page
Click a label to isolate a page. The paid landers run hotter than the shop/PDP pages.
Conversion rate by landing page
collections/shop & the 30-servings PDP convert highest (~3.7–4.7%); the paid landers (rise-2, compare-listicle, rise-2-coffee) sit ~1.6–1.9% — and slipping.
Where a problem can hide even when the totals look clean — e.g. one paid lander getting flooded from one channel.
This view needs a fresh cross-tabulated query from Shopify’s analytics engine (ShopifyQL), which was timing out (500 errors) at build time. The view will be filled in automatically as soon as that engine recovers — no other section depends on it.
05 · Does zero-second traffic hurt conversion or CAC?
Two questions, two answers. Does instant-bounce traffic convert worse? Yes — and the link is much tighter for Instagram (r = -0.59) than site-wide (r = -0.31). Does it drive up CAC? Barely — Instagram zero-second vs CAC is only r = +0.20 (weak) and site-wide is ~0. For comparison, CVR itself moves with CAC far more strongly (r = -0.60). Translation: zero-second share is a conversion-quality signal, not a CAC lever.

Instagram zero-second share vs blended CAC — over time
Red = IG zero-second % (left). Black = blended CAC (right). If the hunch held, the two would rise and fall together; mostly they don’t.
Analyst caveat: blended CAC is driven mostly by paid-spend levels, channel mix and seasonality; Instagram’s zero-second share is one channel’s on-site behavior. The weak positive link likely reflects a shared cause (scaling cold prospecting brings both more instant-bounce IG clicks and higher CAC) rather than zero-second sessions causing CAC. Correlation ≠ causation.
06 · How to read this
The three layers tell one consistent story: zero-second share is a quality signature of each channel and page (paid social & video bounce more than search), and it maps inversely to conversion rate — Google search has the lowest zero-second share and the highest CVR; YouTube the opposite. Across two years no channel or page shows an attack-style step-change in zero-second share, so the recent CVR softness (Instagram ~0.6%, paid landers ~1.5%) is gradual and mix-driven — a campaign & efficiency story, not a traffic-quality attack.
