Landing Page QA Checklist

Message and offer match

Message match is the most common conversion killer. The ad, email, or link that brings a visitor to the page must set an expectation that the page fulfils immediately.

• The headline on the landing page matches or closely mirrors the ad headline or email subject line.
• The offer described in the traffic source (discount, free trial, download, demo) is immediately visible on the page.
• There are no conflicting offers, distracting promotions, or site-wide banners that undercut the primary message.
• The primary keyword or intent from the campaign is reflected in the H1 and first paragraph.
• UTM parameters in the traffic source are correct and will attribute the conversion to the right campaign.

Above-fold clarity

A visitor should understand what the page offers and what to do next within 5 seconds of landing, without scrolling.

• The headline clearly states the value proposition — not the company name or a generic tagline.
• A primary CTA button is visible above the fold on desktop and mobile without scrolling.
• The CTA button text describes the action (e.g. "Start free trial", "Book a demo") — not generic text like "Submit" or "Click here".
• No navigation menu, external links, or distractions pull visitors away from the primary conversion path.
• Hero image or video (if present) reinforces the offer rather than being decorative stock imagery.

Form and CTA flow

Form failures are silent conversion killers. Test every submission path before any traffic arrives.

1. Step 1

   Submit the form with valid data

   Use realistic-looking test data — first name, surname, business email address. Confirm the submission completes without errors.

2. Step 2

   Test required field validation

   Submit the form with missing required fields. Confirm error messages appear clearly next to the relevant fields.

3. Step 3

   Confirm form delivery

   Verify the submission arrives in the CRM or email inbox it is mapped to. Check that no submissions are going to a spam folder or a former employee's address.

4. Step 4

   Check double opt-in (if applicable)

   If a confirmation email is expected after form submission, verify it arrives promptly and contains the correct content and links.

Mobile and speed

Most paid campaign traffic arrives on mobile. A page that works on desktop but breaks on mobile is wasting the majority of your ad spend.

• Test the page on at least two mobile devices or browser developer tools at 375px and 390px widths.
• The form is fully usable on mobile — fields are large enough to tap, keyboard does not obscure the submit button.
• The CTA button is large enough to tap comfortably on a phone screen.
• Run PageSpeed Insights and confirm the mobile performance score is above 70. Address any critical issues flagged.
• Images are compressed and served in a modern format (WebP or AVIF where possible).
• No render-blocking scripts delay the initial page paint.

Tracking and pixels

Without verified tracking, you cannot measure ROI, optimize bids, or prove the campaign is working. Verify all tracking before traffic arrives.

• Google Analytics (or GA4) page view fires correctly on the landing page URL.
• Conversion event fires on form submission — verify in GA4 DebugView or Tag Assistant.
• Google Ads conversion tag fires on the thank-you page or as a form submission event — confirm in Google Ads conversion tracking.
• Meta Pixel (if running Meta ads) fires on the landing page and the thank-you page — verify with Meta Pixel Helper.
• Any other platform pixels (LinkedIn, TikTok, etc.) are verified in their respective debug tools.
• No duplicate pixel fires are occurring — check for double-counting in Tag Manager.

Trust and compliance

Trust signals reduce form abandonment. Compliance elements prevent ad disapprovals and legal exposure.

• At least one trust signal is present above the fold or immediately adjacent to the form: testimonial, logo, review count, or accreditation.
• A privacy policy link is present near the form or in the footer.
• For email capture, a brief statement about data use appears near the submit button (e.g. "We will not share your information").
• If the page collects sensitive data (health, finance), compliance language is verified against applicable regulations.
• Cookie consent banner appears (if required by GDPR/CCPA) and does not block the CTA above the fold.
• Page is not blocked from indexing via noindex tag unless intentionally excluded from search.

Post-submit flow

The moment after form submission is a continuation of the conversion — not the end of it. The thank-you page and follow-up flow need QA just as much as the landing page itself.

• A thank-you page or success message confirms the submission and tells the visitor what happens next.
• The thank-you page URL is distinct from the landing page URL — so conversions can be tracked by URL in analytics.
• Any automated confirmation email is tested: subject line, sender name, content, and any links within it.
• CRM entry is created correctly with all form fields mapped to the right contact properties.
• If a follow-up sequence is triggered, confirm the first email arrives within the expected timeframe.
• Conversion tracking fires on the thank-you page or submit event — not on page load of the landing page.
