Auto-Detection Patterns

1. PPC / Advertising Data

Detect columns like:

• Placement, Campaign, Ad Group, Keyword, Search Term
• Impressions, Clicks, Spend, Cost Per Click (CPC)
• Sales, Revenue, ROAS, ACOS, CTR, Conversion Rate
• Orders, Units, Add-to-Cart, Cart Adds

Auto-generate tabs:

1. OVERVIEW - 6 key metrics + top performers table
2. EXPLORER - Searchable/filterable table with all campaigns/keywords
3. FUNNEL - Impressions → Clicks → Cart Adds → Purchases (with CVR)
4. OPPORTUNITIES - Hidden gems, bottlenecks, drop-offs

2. Sales / E-commerce Data

Detect columns like:

• Date, Product, SKU, Category, ASIN
• Units, Revenue, Profit, Price
• Orders, Customers, Sessions
• Returns, Refunds

Auto-generate tabs:

1. OVERVIEW - Revenue, units, AOV, profit metrics
2. EXPLORER - Product performance table with filters
3. FUNNEL - Sessions → Views → Cart → Purchase (if session data)
4. OPPORTUNITIES - Low stock, high return rate, underperformers

3. Analytics / Traffic Data

Detect columns like:

• Date, Source, Medium, Campaign, Keyword
• Sessions, Users, Pageviews, Bounce Rate
• Conversion Rate, Goal Completions, Events
• Avg Session Duration, Pages per Session

Auto-generate tabs:

1. OVERVIEW - Sessions, users, CVR, bounce rate
2. EXPLORER - Source/medium breakdown with filters
3. FUNNEL - Landing → Engagement → Conversion
4. OPPORTUNITIES - High bounce sources, conversion opportunities

4. Accounting / Financial Data

Detect columns like:

• Date, Account, Category, Transaction Type
• Amount, Debit, Credit, Balance
• Vendor, Customer, Invoice

Auto-generate tabs:

1. OVERVIEW - Total income, expenses, profit, cash flow
2. EXPLORER - Transaction table with filters (vendor, category, date)
3. NO FUNNEL - Not applicable for accounting
4. OPPORTUNITIES - Top expenses, late invoices, cash flow issues

5. Support Tickets / CRM Data

Detect columns like:

• Ticket ID, Status, Priority, Category
• Created Date, Resolved Date, Response Time
• Agent, Customer, Satisfaction Score

Auto-generate tabs:

1. OVERVIEW - Total tickets, avg resolution time, satisfaction
2. EXPLORER - Ticket table with filters (status, agent, category)
3. FUNNEL - New → In Progress → Resolved
4. OPPORTUNITIES - Overdue tickets, low satisfaction, bottlenecks

Tab System (When to Use)

Use Tabs When:

• Dataset has >100 rows (need explorer for search/filter)
• Data supports funnel visualization (impressions→clicks→conversions)
• Multiple opportunity types exist (hidden gems, bottlenecks, drop-offs)

Single Page When:

• Dataset <50 rows (all fits on overview)
• Simple report with few metrics
• No funnel or exploration needed

<script>
document.querySelectorAll('.tab').forEach(tab => {
    tab.addEventListener('click', () => {

        });
        document.querySelectorAll('.tab').forEach(t => t.classList.remove('active'));

        // Show selected tab
        const tabName = tab.getAttribute('data-tab');
        document.getElementById(tabName + '-tab').classList.add('active');
        document.getElementById(tabName + '-tab').classList.remove('hidden');
        tab.classList.add('active');

Opportunity Detection Logic:

Hidden Gem:

• Market share <10% (impressions)
• CVR >0.4% or ROAS >3.0x
• Badge: Purple 💎

Funnel Bottleneck:

• High impressions (>10,000)
• Low CTR (<3%) OR low cart-to-purchase rate (<40%)
• Badge: Red ⚠️

Share Opportunity:

• All metrics above average
• Market share potential (CTR >5%, CVR >0.5%)
• Badge: Green 📊

Priority Calculation:

Impact Score = (Impressions / 1000) × CVR × ROAS
High Impact: >10
Medium Impact: 3-10
Low Impact: <3

Search & Filter Implementation

Search Functionality:

const searchInput = document.getElementById('search-input');
const tableBody = document.getElementById('table-body');

searchInput.addEventListener('input', (e) => {
    const searchTerm = e.target.value.toLowerCase();
    const rows = tableBody.querySelectorAll('tr');

    let visibleCount = 0;
    rows.forEach(row => {
        const text = row.textContent.toLowerCase();
        if (text.includes(searchTerm)) {
            row.style.display = '';
            visibleCount++;
        } else {
            row.style.display = 'none';
        }
    });

    document.querySelector('.results-count').textContent = `${visibleCount} results`;
});

Sortable Table:

document.querySelectorAll('.sortable').forEach(header => {
    header.addEventListener('click', () => {
        const column = header.getAttribute('data-column');
        const rows = Array.from(tableBody.querySelectorAll('tr'));
        const isAscending = header.classList.contains('asc');

        rows.sort((a, b) => {
            const aVal = a.querySelector(`[data-column="${column}"]`).textContent;
            const bVal = b.querySelector(`[data-column="${column}"]`).textContent;

            // Handle numeric vs text sorting
            if (!isNaN(aVal) && !isNaN(bVal)) {
                return isAscending ? aVal - bVal : bVal - aVal;
            }
            return isAscending ? aVal.localeCompare(bVal) : bVal.localeCompare(aVal);
        });

        // Clear existing order
        tableBody.innerHTML = '';
        rows.forEach(row => tableBody.appendChild(row));

        // Toggle sort direction
        document.querySelectorAll('.sortable').forEach(h => h.classList.remove('asc', 'desc'));
        header.classList.add(isAscending ? 'desc' : 'asc');
    });
});

File Naming Convention

Examples:

- website-analytics-dashboard-2025-10-19.html

Quality Gates

CRITICAL - Before delivering ANY dashboard, verify:

🚨 MANDATORY (Dashboard is INVALID without these):

• ✅ CURV header with rotating background animation (.header-shape with @keyframes headerRotate)
• ✅ Hero title with white glow effect (text-shadow: 0 0 25px...)
• ✅ "POWERED BY CURV" text in purple (rgb(157, 78, 221))
• ✅ CURV footer with three lines: title, subtitle, credits
• ✅ Footer credits: "Produced By Danny McMillan | CURV Tools | A Seller Sessions Production 2025"

⚠️ OUTPUT FORMAT REQUIREMENT:

• ✅ Must be standalone HTML file (NOT React JSX, NOT component code)
• ✅ Complete <!DOCTYPE html> with <head> and <body>
• ✅ All CSS in <style> tag (no external stylesheets)
• ✅ All JavaScript in <script> tag (no external files)
• ✅ File opens directly in browser without build tools

Standard Quality Checks:

• ✅ Tab navigation (if >100 rows or funnel exists)
• ✅ All metric cards have icons and tooltips
• ✅ Funnel visualization (if applicable data)
• ✅ Opportunities tab with impact levels
• ✅ Search/filter working in Explorer tab
• ✅ Sortable table headers
• ✅ Color-coded badges (green/yellow/red)
• ✅ Purple accent color rgb(157, 78, 221) used consistently
• ✅ Dark background rgb(3, 12, 27)
• ✅ Responsive layout (works on mobile)
• ✅ JavaScript for tabs, search, sort included
• ✅ All tooltips functional (hover or click)
