The Situation

Your team launches a new product page, a campaign landing page, or a redesigned category page. It looks great. It goes live. Three weeks later, someone notices the conversion rate is below baseline. Or the page isn't ranking. Or PageSpeed Insights gives it a 38.

Now the investigation starts. Was it the 2.4MB hero image? The missing meta description? The render-blocking JavaScript? The fact that the canonical tag points to the wrong URL? The answer is usually several of these at once, layered on top of each other, requiring the same team that built the page to now debug it — interrupting whatever they've moved on to since launch.

This cycle repeats because pre-launch QA for web teams typically covers functionality (does the page load? do the links work?) but not performance, SEO, or conversion readiness. Those checks happen post-launch, if they happen at all — usually triggered by a complaint rather than a process.

The Cost of Post-Launch Discovery

Performance debt compounds. A page with poor Core Web Vitals doesn't just load slowly — it ranks worse, converts worse, and costs more in ad spend because Google Quality Score penalizes slow landing pages. Every day between launch and fix is a day of degraded performance across all traffic to that page.

Rework disrupts the roadmap. The dev team has moved on. They're building the next feature, the next page, the next sprint commitment. Pulling them back to fix a launched page is context-switching at its most expensive. The fix itself might take 30 minutes, but the interruption costs half a day.

Issues stack. A single page can have a tech SEO problem (broken canonical), a content problem (thin meta description), a performance problem (unoptimized images), and a CRO problem (CTA below fold on mobile) — simultaneously. Without a comprehensive check, the team fixes one, thinks they're done, and the page continues underperforming because three other issues remain.

What the Landing Page Auditor Does

Enter a URL. Choose what to audit. Get a report with specific, implementable fixes.

Available audit types (run all or select): Tech SEO (canonical tags, indexation, structured data, hreflang), Content SEO (title tags, meta, heading hierarchy, content depth), Core Web Vitals / Performance (LCP, INP, CLS, render-blocking resources), and CRO (CTA visibility, form usability, above-the-fold content, mobile layout).

Not "improve page speed." Instead: "LCP is 4.2 seconds. Primary cause: hero image at 2.4MB served as PNG. Compress to WebP (estimated 180KB), add width/height attributes to prevent CLS, and lazy-load all below-the-fold images. Expected LCP improvement: ~2.8 seconds."

Not "optimize for SEO." Instead: "Title tag is 'New Product | Your Store' — missing primary keyword. Recommended: '[Product Name] — [Category] | Your Store'. Canonical tag is set to /product/old-slug which returns 404. Update to current URL."

Every fix is specific enough to hand directly to a developer as a task — no interpretation needed. The report reads like a pull request review, not a strategy document.

Prioritization: Issues are ranked by severity and impact. A broken canonical on a page receiving 500 organic visits/day is flagged before an unoptimized image on a page with 10 visits/week. The team works top-down, addressing the highest-impact items first.

How Teams Use It

Pre-launch QA. Run the auditor on staging or after deploy, before promoting the URL. Catch the issues before your customers and Google encounter them.

Post-launch investigation. A page is underperforming and nobody knows why. Run the auditor. Get a diagnosis in minutes instead of spending a morning in DevTools.

Periodic health checks. Run it quarterly on your top-traffic pages. Site updates, plugin changes, and CMS modifications can introduce regressions that affect pages you haven't touched. The auditor catches what your team can't manually track across hundreds of pages.

Agency handoffs. If you work with an external dev or SEO agency, the audit report is a precise deliverable spec. No ambiguity about what needs fixing or how.

The Shift

Before: pages launch with hidden issues, problems surface weeks later through indirect signals, and the team does rework that could have been prevention.

After: pages launch clean. Issues are caught before they cost you traffic, conversions, or ad budget. And when something does slip through, diagnosis takes minutes instead of hours.

The simplest version: fix it before it's live, not after it's lost you money.
