Landing Launch Check

Landing Page Final Launch Check

A focused, evidence-based audit that runs after the landing page is built and deployed, before declaring it launch-ready. Designed for marketing landing pages that extend a shared app layer (e.g. a Nuxt app-base with i18n, auth, and compliance components inherited by B2C/B2B apps).

When to use

• A new landing page has been deployed and needs a final sign-off
• A landing page was built on top of a shared app layer and may have inherited wrong defaults
• The site targets multiple locales (e.g. Swedish + English) and needs per-locale SEO
• The site targets EU users and needs GDPR/ePrivacy compliance
• Before submitting to Google Search Console and AI search engines

What this skill checks

Four dimensions, each with concrete pass/fail criteria:

1. Technical SEO — meta tags, canonical, hreflang, sitemap, robots.txt
2. AEO/AIO/GEO — structured data (JSON-LD) for AI search engines and rich results
3. i18n correctness — per-locale meta, lang attribute, og:locale
4. EU compliance — cookie consent, privacy policy, terms, GDPR Art. 13 elements

Prerequisites

• The landing page is deployed and accessible via its public URL
• curl available for HTTP inspection
• Python 3 for parsing HTML
• (Optional) Playwright + a Chrome instance with CDP for Google Search Console submission
• (Optional) gh CLI for creating follow-up issues

Audit procedure

Phase 1: Crawl the live pages

Fetch the HTML for every locale variant and the robots.txt:

curl -s https://example.com/ -o /tmp/landing-sv.html
curl -s https://example.com/en -o /tmp/landing-en.html
curl -s https://example.com/robots.txt -o /tmp/robots.txt
curl -s -o /dev/null -w "%{http_code}" https://example.com/sitemap.xml

Phase 2: Technical SEO audit

For each locale variant, extract and check:

import re
html = open('/tmp/landing-sv.html').read()
checks = {
    'title': re.findall(r'<title>([^<]*)</title>', html),
    'lang': re.findall(r'<html[^>]*lang="([^"]*)"', html),
    'description': re.findall(r'name="description" content="([^"]{0,80})', html)[:1],
    'canonical': re.findall(r'rel="canonical" href="([^"]*)"', html),
    'hreflang': re.findall(r'hreflang="([^"]*)"', html),
    'og:locale': re.findall(r'og:locale" content="([^"]*)"', html),
    'og:image': re.findall(r'og:image" content="([^"]{0,90})', html),
    'og:url': re.findall(r'og:url" content="([^"]*)"', html),
    'twitter:card': re.findall(r'twitter:card" content="([^"]*)"', html),
    'json-ld': len(re.findall(r'application/ld\+json', html)),
    'robots_meta': re.findall(r'<meta name="robots" content="([^"]*)"', html),
}

Pass criteria (per locale):

robots.txt checks:

User-Agent: *
Allow: /
Disallow: /login          # inherited auth pages shouldn't be indexed
Disallow: /register
Disallow: /en/login
Sitemap: https://example.com/sitemap.xml

Sitemap checks:

• /sitemap.xml returns 200
• Contains all public URLs
• Has xhtml:link rel="alternate" with hreflang for locale variants

Phase 3: AEO/AIO/GEO audit (structured data)

AI search engines (Google AI Overviews, Perplexity, ChatGPT Search, Bing Copilot) rely on structured data to cite sources. Check for JSON-LD presence and validity:

import json, re
html = open('/tmp/landing-sv.html').read()
m = re.search(r'<script type="application/ld\+json">(.*?)</script>', html, re.DOTALL)
if m:
    data = json.loads(m.group(1))
    types = [g['@type'] for g in data.get('@graph', [data])]
    print('JSON-LD types:', types)

Recommended JSON-LD types for a landing page:

Validation:

• JSON must be valid (parse without error)
• Test at https://search.google.com/test/rich-results
• Test at https://validator.schema.org/

Key AEO insight: The FAQ content must be localized per locale — an EN page serving SV FAQ text confuses AI engines. Use i18n keys in the JSON-LD generator, not hardcoded strings.

Phase 4: i18n correctness audit

The most common landing page bug: a shared app layer hardcodes one locale's meta in nuxt.config.ts or definePageMeta(), and every locale variant serves the same meta.

Check each locale variant independently:

# SV page should have sv-SE lang, sv_SE og:locale, Swedish title
curl -s https://example.com/ | grep -oP '(?<=lang=")[^"]*|(?<=og:locale" content=")[^"]*|(?<=<title>)[^<]*'

# EN page should have en-GB lang, en_GB og:locale, English title
curl -s https://example.com/en | grep -oP '(?<=lang=")[^"]*|(?<=og:locale" content=")[^"]*|(?<=<title>)[^<]*'

Common failures when extending a shared app layer:

1. app.head.htmlAttrs.lang hardcoded in nuxt.config.ts → all locales get same lang
2. definePageMeta({ title: '...' }) hardcoded → all locales get same title
3. useSeoMeta({ description: '...' }) hardcoded → all locales get same description
4. og:image URL points to staging domain → leaked from default config
5. No i18n.baseUrl → useLocaleHead() can't generate canonical/hreflang

Fix pattern (Nuxt + @nuxtjs/i18n):

// In the page component, NOT in nuxt.config.ts
const { t, locale } = useI18n()
const i18nHead = useLocaleHead({ seo: true, lang: true })

useHead({
  htmlAttrs: computed(() => i18nHead.value.htmlAttrs ?? {}),
  link: computed(() => i18nHead.value.link ?? []),
  meta: computed(() => i18nHead.value.meta ?? []),
})

useSeoMeta({
  title: () => t('landing.meta.title'),
  description: () => t('landing.meta.description'),
  ogLocale: () => locale.value === 'sv' ? 'sv_SE' : 'en_GB',
  // ... all meta from i18n keys, not hardcoded
})

// nuxt.config.ts — set baseUrl so useLocaleHead can generate canonical/hreflang
i18n: {
  baseUrl: 'https://example.com',
}

Phase 5: EU compliance audit

Business classification (do this first):

• Is it B2C or B2B?
• Does it process personal data? (cookies, analytics, forms, auth)
• Does it target EU/EEA users? (GDPR + ePrivacy apply)
• Does it have third-party trackers? (GA, Meta Pixel, Hotjar, etc.)

Required pages check:

for p in privacy terms cookie-settings; do
  echo -n "/$p: "; curl -s -o /dev/null -w "%{http_code}" https://example.com/$p
done

Cookie consent banner check:

1. Banner appears on first visit (no prior consent cookie)
2. "Accept All" and "Essential Only" buttons are equally prominent (no dark pattern)
3. Consent is recorded with a timestamp
4. Consent can be withdrawn via /cookie-settings
5. Pre-consent tag firing: no third-party trackers load before consent is given

Privacy policy GDPR Art. 13 elements:

Scan the privacy policy text for these required elements:

import re, html as H
h = open('/tmp/priv.html').read()
text = H.unescape(re.sub(r'\s+', ' ', re.sub(r'<[^>]+>', ' ', re.sub(r'<script.*?</script>', '', h, flags=re.DOTALL))))
kws = ['personuppgiftsansvarig', 'rättslig grund', 'lagringstid', 'rättigheter', 'IMY', 'tredje', 'överföring', 'e-post']
for k in kws:
    print(f'{k}: {k.lower() in text.lower()}')

Risk classification:

• Low risk: No third-party trackers, first-party cookies only, no forms → compliance is mostly about having the pages present
• Medium risk: Analytics with consent gating, auth/login collecting email + name
• High risk: Third-party trackers, payment processing, cross-border data transfer, children's data → legal review required

Phase 6: Submit to Google Search Console (optional, via CDP)

If the user wants to submit the sitemap to Google Search Console using their already-logged-in Chrome:

1. Ensure Chrome is running with --remote-debugging-port=9222
2. Connect via Playwright connectOverCDP
3. Navigate to the Sitemaps page
4. Fill the sitemap input with the full URL (e.g. https://example.com/sitemap.xml, not just sitemap.xml)
5. Click the Submit button (Material Design div.U26fgk.O0WRkf, not a native <button>)
6. Verify the sitemap appears in the list with status "Success"

import { chromium } from 'playwright'
const browser = await chromium.connectOverCDP('http://127.0.0.1:9222')
const ctx = browser.contexts()[0]
const page = await ctx.newPage()
await page.goto('https://search.google.com/search-console/sitemaps?resource_id=sc-domain:example.com', { waitUntil: 'networkidle' })
await page.waitForTimeout(3000)
await page.locator('input[aria-label="Enter sitemap URL"]').fill('https://example.com/sitemap.xml')
await page.locator('div.U26fgb.O0WRkf').filter({ hasText: 'Submit' }).first().click()
await page.waitForTimeout(5000)
// Verify: look for "Success" in the sitemap table row

Gotcha: For sc-domain: properties, the sitemap URL must be the full HTTPS URL, not a relative path. Relative paths like sitemap.xml will return "Invalid sitemap address".

Phase 7: Generate report

Output a structured report with:

1. Summary table — dimension × status (Pass/Fail/Warning)
2. Findings — each issue with severity, evidence, and fix
3. Remediation checklist — actionable items, ordered by severity
4. Compliance disclaimer — "This audit is not legal advice. High-risk businesses should have final materials reviewed by qualified counsel."

Severity levels

Common failure patterns (from real audits)

1. SV page serves EN meta — nuxt.config.ts hardcodes English title/description; the SV page (default locale) serves English to Google.se
2. EN page has lang="sv" — app.head.htmlAttrs.lang hardcoded in shared config; useLocaleHead() not used
3. No canonical URLs — i18n.baseUrl not set; useLocaleHead() can't generate them
4. No hreflang alternates — same cause as above; Google can't associate locale variants
5. og:image points to staging — default config leaked from dev environment
6. Zero structured data — no JSON-LD at all; AI search engines have no structured signal
7. Inherited auth pages indexable — /login, /register from shared app layer not disallowed in robots.txt
8. No sitemap.xml — static sitemap not created; Google has to discover URLs by crawling
9. Privacy policy missing GDPR Art. 13 elements — controller identity, legal basis, retention period, IMY complaints right not mentioned
10. Sitemap submitted as relative path — Google Search Console rejects sitemap.xml; needs full https://example.com/sitemap.xml

Tools used

• curl — fetch live HTML and check HTTP status
• python3 with re — parse HTML meta tags and JSON-LD
• playwright (optional) — submit sitemap to Google Search Console via CDP
• gh CLI (optional) — create follow-up issues for remediation items
