Executive Summary (на български)

Пълният QA одит на целия сайт засече 12 реални дефекта: 6 Critical, 1 High, 3 Medium, 2 Low. Най-сериозните проблеми са в самите калкулатори — 6 от 12 калкулатора са дефектни: при 3 (CPC/CPM/CTR) резултатът се изчислява правилно, но остава невидим за потребителя (CSS .hidden{display:none!important} побеждава inline стила); при други 3 (CPA/CPL/AOV) калкулаторът е напълно нефункционален (липсва JS логика). ROAS работи, но добавката "profit margin" е счупена. Блогът (50 поста) е здрав като съдържание, но нито един пост няма FAQPage schema (пропуснати rich results). Достъпността има 49 axe нарушения (10 critical). Gate статусът: 6/7 gates PASS; E2E FAIL (1 тест, но невъзпроизводим — asset-ът връща 200 live и локално → flaky/serve race, не реален дефект).

Executive Summary (English)

Full-site QA audit found 12 real defects: 6 Critical, 1 High, 3 Medium, 2 Low. The most severe are in the calculators themselves — 6 of 12 calculators are defective: 3 (CPC/CPM/CTR) compute the correct result but render it invisible to the user (.hidden{display:none!important} overrides the inline reveal); 3 (CPA/CPL/AOV) are completely non-functional (no JS handler wired up). ROAS works, but its "profit margin" add-on is broken. The blog (50 posts) is content-healthy but 0/50 posts have FAQPage structured schema. Accessibility has 49 axe violations (10 critical). Gate status: 6/7 gates PASS; E2E FAIL (1 test, but not reproducible — the asset returns HTTP 200 live and locally, so it is a flaky/serve-readiness issue, not a real defect).

Testing Scope

12 calculators (CPC, CPM, CTR, CPA, CPL, AOV, ROAS, Revenue, E-commerce Profit, Email Marketing, Engagement Rate, Campaign Funnel, ROI/LTV, + Marketing Mix Optimizer, Marketing Budget Planner) — driven on the live production URL via headless Chromium (Playwright), with real input values, result-visibility checks, edge cases, and console-error capture.
50 blog posts — JSON-LD schema audit, FAQ presence, internal/source link audit against built dist/.
Global: navigation, footer cross-link to oddscalculator.xyz, share buttons, cookie consent, 404 page, responsive (mobile 375px screenshots), accessibility (axe-core 4.9.1).
Evidence: screenshots + machine-readable results at C:\Users\Nikola\qa-audit-temp\qa-results.json and C:\Users\Nikola\qa-audit-temp\shots\*.png.

Per-Issue Findings

🔴 CRITICAL #1 — CPC calculator computes correctly but the result is invisible

Category: Functional / Visual
URL: https://adscalculator.xyz/cpc-calculator/
Description: Typing into totalCost + numClicks correctly computes CPC and writes it into #header-result-value (verified $2.00 for 1000/500), but #header-result-container stays display:none with the hidden class still applied → the user sees no result.
Root cause: style/sources-tables.css:127 → .hidden { display: none !important; }. The cpc branch in js/simple-main.js reveals the result with headerResultContainer.style.display = "flex" without removing the hidden class. The !important rule wins, so the container is never shown. (ROAS works only because its branch does classList.remove("hidden").)
Repro: Navigate to /cpc-calculator/, fill totalCost=1000, numClicks=500. DOM shows #header-result-value = "$2.00" but getComputedStyle(#header-result-container).display === "none", offsetParent === null, rectH === 0.
Expected: Result card visible with "$2.00".
Actual: Result computed but hidden; user-facing calculator appears dead.
Console errors: none.
Screenshot: MEDIA:C:\Users\Nikola\qa-audit-temp\shots\cpc-desktop.png

🔴 CRITICAL #2 — CPM calculator result invisible (same root cause as #1)

Category: Functional / Visual
URL: https://adscalculator.xyz/cpm-calculator/
Description: Computes $5.00 for cost=500/impressions=100000 but result card remains hidden (display:none, hidden class retained).
Root cause: Same as #1 — js/simple-main.js cpm branch sets style.display="flex" without classList.remove("hidden"); .hidden{display:none!important} hides it.
Repro: Fill cost=500, impressions=100000 → value "$5.00" present, container display:none.
Expected: Visible "$5.00". Actual: Hidden. Console: none.
Screenshot: MEDIA:C:\Users\Nikola\qa-audit-temp\shots\cpm-desktop.png

🔴 CRITICAL #3 — CTR calculator result invisible (same root cause as #1)

Category: Functional / Visual
URL: https://adscalculator.xyz/ctr-calculator/
Description: Computes 5.00% for impressions=10000/clicks=500 but result card hidden.
Root cause: Same as #1.
Repro: Fill impressions=10000, clicks=500 → value "5.00%" present, container display:none.
Expected: Visible "5.00%". Actual: Hidden. Console: none.
Screenshot: MEDIA:C:\Users\Nikola\qa-audit-temp\shots\ctr-desktop.png

🔴 CRITICAL #4 — CPA calculator completely non-functional

Category: Functional
URL: https://adscalculator.xyz/cpa-calculator/
Description: Typing totalCost + conversions (or clicking the on-page Calculate button) does nothing — #header-result-value stays at the placeholder $0.00 and the result container stays hidden. There is no JavaScript handler attached to this calculator.
Root cause: cpa-calculator.html loads pageScripts: [calculations.js, simple-main.js, utils.js]. js/simple-main.js only wires up branches for #roasResult, #cpc, #cpm, #ctr, #revenueResult — there is no cpa branch. The input element id="cpa" exists, but nothing reads it. No cpa-main.js / calculator-controller.js is loaded.
Repro: Fill totalCost=1000, conversions=10 → #header-result-value = "$0.00", #header-result-container display:none. Clicking the Calculate button also has no effect.
Expected: CPA = totalCost/conversions = $100.00, visible. Actual: "$0.00", hidden. Console: none (silent failure).
Screenshot: MEDIA:C:\Users\Nikola\qa-audit-temp\shots\cpa-desktop.png

🔴 CRITICAL #5 — CPL calculator completely non-functional

Category: Functional
URL: https://adscalculator.xyz/cpl-calculator/
Description: Same as #4 — no handler attached; totalCost + leads produce no result ("$0.00", hidden). Missing cpl branch in js/simple-main.js; loads only calculations.js, simple-main.js, utils.js.
Repro: Fill totalCost=1000, leads=20 → "$0.00", hidden. Expected CPL = $50.00.
Console: none.
Screenshot: MEDIA:C:\Users\Nikola\qa-audit-temp\shots\cpl-desktop.png

🔴 CRITICAL #6 — AOV calculator completely non-functional

Category: Functional
URL: https://adscalculator.xyz/aov-calculator/
Description: Same as #4/#5 — no handler attached; totalRevenue + orders produce no result ("$0.00", hidden). aov-calculator.html loads only calculations.js, simple-main.js, utils.js; there is no aov branch in simple-main.js and no dedicated AOV script.
Repro: Fill totalRevenue=5000, orders=100 → "$0.00", hidden. Expected AOV = $50.00.
Console: none.
Screenshot: MEDIA:C:\Users\Nikola\qa-audit-temp\shots\aov-desktop.png

Shared root cause for #1–#6: (a) .hidden { display:none !important } defeats any reveal that only sets element.style.display without also calling classList.remove("hidden"); (b) simple-main.js is missing cpa/cpl/aov calculator branches. Fix: add classList.remove("hidden") (and add it back on reset) wherever results are revealed, and add the three missing three-variable branches to simple-main.js.

🟠 HIGH #7 — ROAS "Enable Profit Margin" add-on is unusable

Category: Functional
URL: https://adscalculator.xyz/roas-calculator/
Description: ROAS core works (revenue=1000/cost=200 → "500.00%", verified). But toggling the "Enable Profit Margin" checkbox does not reveal the margin input (#profitInputContainer stays display:none), so a real user cannot enter a margin to get break-even / net-profit. The math itself is correct (when the margin is set programmatically, break-even computes to "500.0% (5.00)").
Root cause: roas-calculator.html:55 → <div id="profitInputContainer" class="hidden mt-2">. The change handler in js/simple-main.js sets profitInputContainer.style.display = this.checked ? "block":"none" without removing the hidden class, and .hidden{display:none!important} hides it.
Repro: page.check('#enableProfit') / dispatch change → getComputedStyle(#profitInputContainer).display stays "none"; #profitMargin offsetParent === null.
Expected: Checking the box reveals the margin input. Actual: Input stays hidden. Console: none.
Screenshot: MEDIA:C:\Users\Nikola\qa-audit-temp\shots\roas-desktop.png

🟡 MEDIUM #8 — No FAQPage structured data on any blog post (50/50)

Category: Content / SEO
URL: e.g. https://adscalculator.xyz/blog/cpm-benchmarks-2025/
Description: All 50 blog posts contain FAQ content in the HTML, and all 50 have valid BlogPosting/Article JSON-LD (inside @graph), but none include a FAQPage node. As a result the site cannot earn FAQ rich results in search.
Root cause: Blog template / content pipeline never emits FAQPage schema even when an FAQ section is present. (scripts/validate-schemas.js passes because the existing JSON is valid — it does not assert FAQPage presence.)
Repro: node audit over dist/blog/*/index.html: Posts WITH FAQPage schema: 0 / 50.
Expected: Posts with FAQ sections should also emit FAQPage JSON-LD. Actual: 0/50.
Severity note: Medium — SEO/visibility impact, not a functional break.

🟡 MEDIUM #9 — E2E gate FAILED (flaky, non-reproducible)

Category: Console / Process (test infra)
URL: npx playwright test (baseURL http://localhost:8080)
Description: The E2E suite reports 9 passed, 1 failed — smoke-regression › cpm-benchmarks-2025: every image preload resolves to a real file. Manual re-verification shows the asset /cpm-benchmarks-2025-300.webp returns HTTP 200 on the live site AND on local serve.js (both confirmed via curl). The failure is therefore a flaky serve-readiness race / environment issue, not a broken asset.
Repro of non-defect: curl -I https://adscalculator.xyz/cpm-benchmarks-2025-300.webp → 200; curl -I http://localhost:8080/cpm-benchmarks-2025-300.webp → 200. The file exists at dist/cpm-benchmarks-2025-300.webp and dist/assets/....
Expected: E2E green. Actual: 1 red test, but asset confirmed healthy.
Action for dev: Re-run E2E on a warm serve.js (the webServer reuseExistingServer + parallel test start may race); not a production defect.

🟡 MEDIUM #10 — E2E coverage gap (10 calculators untested)

Category: Testing gap
URL: e2e/tests/*.ts
Description: The E2E suite covers only: Homepage (title + ROAS math), Revenue calculator, 3 sampled blog preloads, and blog index/nav — 8 test cases total. The 10 other calculators (CPC, CPM, CTR, CPA, CPL, AOV, E-commerce Profit, Email Marketing, Engagement Rate, Campaign Funnel, ROI/LTV, Marketing Mix, Marketing Budget) have zero E2E coverage, which is exactly why the Critical defects in #1–#6 shipped undetected.
Action for dev: Add per-calculator E2E specs asserting computed result text + container visibility (the visibility check would have caught #1–#3).

🟢 LOW #11 — CPA/CPL/AOV absent from "Related Calculators"

Category: Content / Discoverability
URL: any calculator page (e.g. https://adscalculator.xyz/cpc-calculator/)
Description: _includes/related-calculators.html links ROAS, CPC, CPM, CTR, Campaign Funnel, ROI/LTV, E-commerce Profit, Email Marketing, Engagement Rate, Revenue, Marketing Mix + 3 blog posts — but omits CPA, CPL, AOV, the three broken calculators. (Coincidentally these are the broken ones; once fixed they should be cross-linked.)
Severity: Low.

🟢 LOW #12 — No console errors site-wide (positive finding)

Category: Console
Description: Across all 15 calculator/tool pages driven headlessly, 0 console errors and 0 page exceptions were captured. JS loads cleanly; the defects are logic/visibility bugs, not crashes. Cookie banner, 404 page, header navigation, and share-button ("Calculate First!" gate before a calculation) all behaved correctly.
Note: This is a clean signal — recorded to counterbalance the functional defects and confirm they are silent logic bugs, not runtime errors.

Testing Notes

What was tested (with real evidence):

All 12 calculators + 3 extra tools driven on the live production URL via headless Chromium (Playwright), with real numeric inputs, result-text assertions, and getComputedStyle/visibility probes.
Edge cases on CPC: negative input → "cannot be negative" error + result hidden ✅; division by zero → "Division by zero is not allowed." ✅; huge value (1e12/2) → "$500,000,000,000.00" computed ✅.
Engagement Rate confirmed working (button-triggered: clicking Calculate → "3.200%", 160 engagements) — initial "0.000%" was a harness false negative, not a bug.
Revenue, E-commerce Profit, Email Marketing, Campaign Funnel, ROI/LTV, Marketing Mix, Marketing Budget all compute and render visible results.
Blog: 50 posts scanned for JSON-LD (all have BlogPosting/Article via @graph), FAQ content (50/50 present), internal links (0 posts with zero), source links (0 posts without).
Global: cookie consent (banner dismisses), 404 page (proper 404 + content), header nav (navigates), share button ("Calculate First!" before a calculation), responsive (375px mobile screenshots captured for every page), accessibility (axe-core 4.9.1).

What was NOT tested / limitations:

Core Web Vitals (LCP/INP/CLS) were not measured with lab/field metrics (no Lighthouse run). Only mobile-width screenshots were captured. Recommend a Lighthouse pass on the key pages.
Complex-calculator math correctness was not independently re-derived — only that they compute a result and render it visibly. Formulas were spot-checked via source for CPC/CPM/CTR/ROAS; deeper formula verification for Revenue/E-com/Email/Funnel/ROI-LTV is recommended.
Browser-Use harness was unavailable (requires manual "Allow remote debugging" in Chrome — an interactive step). All browser evidence was therefore collected via Playwright headless, which is fully sufficient and arguably more reliable for assertions.
Horizontal-overflow / responsive interaction was not exhaustively checked beyond 375px screenshots.

Blockers: None. The only environmental caveat is the E2E flaky failure (#9), which is test-harness timing, not a site defect.
