Block: top-products

A 5-row table of the products with the most session traffic in the selected period, with each product's add-to-cart rate alongside.

What it shows

Column	Format	Notes
Top Products by Traffic	Product title	Truncate with ellipsis if very long
Sessions	Integer	Sessions that viewed the product page
Add to Cart	Percentage with benchmark indicator	ATC sessions ÷ product-view sessions

The Add to Cart column carries the centered-bar benchmark indicator — each row's ATC rate is compared to the site-wide ATC rate (the topline reference), with the tick at the topline value. Above-topline rates show in success-green; below in warning-orange.

Data source

Noibu only. Product titles, view events, and ATC events all come from Noibu's session data via the VIEWED_PRODUCT_TITLES and ADDED_TO_CART_PRODUCT_TITLES collections — works for any merchant Noibu monitors regardless of commerce platform.

If the user has a commerce-platform connector (e.g., Shopify) it can enrich the product titles with images or canonical URLs, but it's not required for this block.

MCP calls

One query per period. Group by product title (arrayJoin on VIEWED_PRODUCT_TITLES), with two measures:

{
  "queryInput": {
    "measures": [
      { "aggregate": { "measureAlias": "sessions", "measureFunc": "COUNT", "target": { "field": "SESSION_ID" } } },
      {
        "aggregate": {
          "measureAlias": "atc_sessions",
          "measureFunc": "COUNT",
          "target": { "field": "SESSION_ID" },
          "filters": [{ "fieldName": "ADDED_TO_CART_COUNT", "operator": "GREATER_THAN", "comparisonValues": ["0"] }]
        }
      }
    ],
    "groupBy": {
      "arrayJoin": { "arrayJoinCollection": "VIEWED_PRODUCT_TITLES" }
    },
    "orderBy": { "measureAlias": "sessions", "direction": "DESCENDING" },
    "limit": 5
  }
}

Compute atcPct = atc_sessions / sessions * 100 per row.

Site-wide ATC rate (for the indicator)

The benchmark tick on each row's indicator is the site-wide ATC rate over the same period. Compute it once:

site_atc_pct = (sessions where ADDED_TO_CART_COUNT > 0) / (sessions where PRODUCT_VIEW_COUNT > 0) × 100

The skill computes this from one of the existing queries (purchase-funnel pulls these counts already) so this block doesn't need an extra call — just read the values from the funnel block's response if both blocks are enabled. Otherwise, run the site-wide query separately.

Methodology tooltips

The "Add to Cart" header is spelled out — no acronym tooltip needed.

If the user wants more detail about how the site-wide rate is computed, that lives in the centered-bar indicator's hover tooltip ("X% above/below site avg") which is automatic.

Empty state

If the user's commerce events aren't being captured by Noibu (no product-view events recorded in the window), render the block with a "No product data in this window — check that product page tracking is firing" message instead of an empty table.

Polarity

Higher ATC rate is better. Above-topline rows render the indicator in success-green; below in warning-orange.
