Publishing a design with errors is expensive: wasted impressions, broken links, and brand credibility damage. This QA checklist prevents the most common publish errors.

Design QA Checklist for Marketers Before Publish

Every marketer has published a design with an error — a typo in the headline, a broken link, a misaligned element on mobile, a CTA that points to the wrong page. Each error is a campaign quality failure that erodes trust with the prospect and the internal team.

This checklist prevents the most expensive and most common publish errors.

Pre-Publish QA Checklist: Landing Pages

Copy:

• Headline reviewed for typos, grammar, and factual accuracy
• Subheadline reviewed (easy to miss in the rush to get the hero right)
• Body copy reviewed for: typos, consistent punctuation, consistent sentence case
• CTA copy matches the intent of the page (not "Get Started" when the intended action is "Book a Call")
• Form field labels are clear and grammatically correct
• Footer disclaimers, privacy links, and legal copy are current

Links:

• All CTAs point to the correct destination (test every button, every link)
• CTA redirects correctly on mobile (test on an actual mobile device, not just a browser resize)
• Form submission confirmation redirects to the correct thank-you page
• Navigation links are working (don't break your nav when publishing a new page)
• Social sharing links (if present) generate the correct preview card

Visual:

• Hero image loads on mobile at the correct crop (not cut off at important content)
• All images have working URLs (no broken image icons)
• Favicon is present and correct
• Page title and meta description are set (don't publish with no title or generic template title)
• OG image is set for social sharing (the image that appears when the URL is pasted in Slack or LinkedIn)

Technical:

• Page loads in under 3 seconds (use PageSpeed Insights to check)
• Analytics tracking is working (verify the form submission fires your conversion event)
• UTM parameters on CTAs are consistent with your campaign naming convention

Pre-Publish QA Checklist: Ad Creative

Copy:

• Primary text reviewed for typos
• Headline reviewed (LinkedIn character limits: 70 characters for headline)
• CTA matches the landing page (if the ad says "Book a Fit Check," the landing page should also say "Book a Fit Check")

Visual:

• Creative reviewed at actual display size (not at 100x zoom in Figma)
• Text is legible on both light and dark screen backgrounds
• Logo is visible and correct
• Creative is correctly cropped for all required aspect ratios (an ad that looks great at 1:1 may have logo cropped off at 1200x628)

Links:

• Destination URL is correct
• UTM parameters are appended and correct
• Landing for the ad destination is live and working

Pre-Publish QA Checklist: Email

• Send test email to yourself and check on both desktop and mobile
• Subject line: 40-50 characters for mobile preview
• Preheader text is set and compelling
• All links tested (click every link in the test email)
• Images display correctly with images enabled
• Email display with images blocked — is the message still readable?
• From name and email address are correct
• Unsubscribe link is present and functional
• Plain-text version is set and readable

The 10-Minute Review Standard

A complete QA pass should take under 10 minutes for a single-page landing page or ad set. If it's taking longer, you either have a complex asset that warrants more time, or the checklist is being worked through sequentially instead of with a second set of eyes.

A second reviewer catches errors the creator misses because they stop seeing their own work. The creator has read the copy so many times they're no longer reading — they're pattern matching from memory.

At Sako, QA is built into the delivery workflow. Before any asset leaves the pod, it goes through a standardized technical and content check. Errors caught at QA don't reach the client.
