The Landing Page Audit Checklist Every PPC Manager Needs

You can build the best Google Ads campaign in the world — perfect structure, tight keywords, compelling copy — and it will still fail if the landing page doesn't convert. Every agency learns this the hard way. Usually when a client is already angry.

The problem is that most PPC managers never systematically audit the landing page. They glance at it, maybe check if the form works, and move on. That's not enough. A proper landing page audit is the difference between a campaign that scrapes by and one that actually makes money.

We built this checklist from hundreds of campaign diagnoses we've run for agencies and freelancers. These are the exact items we check, in the exact order we check them. Every item includes why it matters and how to verify it. Print it out. Use it on every client account before you launch — and again any time conversions start slipping.

Section 1: Speed & Technical Performance

Nothing else on this list matters if the page doesn't load fast. Over half of mobile visitors abandon a page that takes longer than 3 seconds to load. You could have perfect copy, perfect design, and perfect trust signals — none of it matters if nobody sticks around to see it.

Page loads in under 3 seconds on mobile

Why it matters:Google's own data shows 53% of mobile visits are abandoned if the page takes longer than 3 seconds. Every second of delay costs you conversions — and you're paying for those clicks whether the page loads or not.

How to check: Run the URL through Google PageSpeed Insights. Look at the mobile tab specifically. Anything above 3 seconds needs immediate attention. Also check the "Opportunities" section — it will tell you exactly what's slowing it down (uncompressed images, render-blocking scripts, etc.).

Core Web Vitals pass

Why it matters: LCP, INP, and CLS directly affect both user experience and Quality Score. A page with poor Core Web Vitals tells Google the landing page experience is bad — which means higher CPCs and lower ad positions. This is no longer optional.

How to check: PageSpeed Insights shows Core Web Vitals at the top of the report. For field data (real users), check Google Search Console under Core Web Vitals. You want all three metrics green. If CLS is failing, look for images without width/height attributes or dynamically injected content that shifts the layout.

Mobile responsive design

Why it matters:60-70% of Google Ads clicks come from mobile devices in most industries. If the page breaks on a phone, you're burning the majority of your ad spend. Not "responsive-ish" — actually responsive. Text readable without zooming. Buttons you can tap. Forms you can fill out.

How to check:Open the page on an actual phone. Chrome DevTools mobile simulation is fine for a quick check, but it doesn't catch everything. Pull the page up on an iPhone and an Android device. Try to fill out the form. Try to tap the phone number. Try to read the headline without zooming. If you have to pinch-zoom, it fails.

SSL certificate active (HTTPS)

Why it matters:Google Ads will flag landing pages without HTTPS. Browsers show a "Not Secure" warning. Visitors see that warning and leave. There's also a Quality Score penalty. There is no reason in 2026 to run a landing page without SSL.

How to check: Look for the padlock icon in the browser bar. Click it and make sure the certificate is valid and not expired. Also check that http:// properly redirects to https:// — sometimes the SSL cert exists but the redirect is missing, and Google Ads may be sending traffic to the http version.

No broken images, scripts, or 404 resources

Why it matters: Broken images make the page look abandoned. Failed scripts can break forms, tracking, and interactive elements. You might not see it because your browser has things cached — but a new visitor coming from an ad will see every broken piece.

How to check:Open Chrome DevTools, go to the Console tab, and load the page. Look for red errors. Then check the Network tab — filter by status codes and look for any 404s or failed requests. Do this in an incognito window so caching doesn't hide problems.

Section 2: Message Match

Message match is the single biggest conversion lever on a landing page. The visitor clicked an ad with a specific promise. The landing page needs to immediately confirm they're in the right place. If there's any disconnect between what the ad said and what the page says, you lose them.

Headline matches the ad copy

Why it matters:The visitor just read your ad headline. They clicked because that headline resonated. When they land on the page, the first thing they see needs to reinforce that same message. If the ad says "Get a Free Roof Estimate" and the landing page says "Welcome to ABC Roofing," the visitor's brain doesn't connect the two. They question if they clicked the right thing. They leave.

How to check:Pull up the ad in Google Ads. Copy the headline. Open the landing page. Compare them side by side. They don't need to be word-for-word identical, but the core offer and language need to match. Screenshot both and put them next to each other — if the connection isn't immediately obvious, it's a mismatch.

Offer on the page matches the ad's promise

Why it matters:If the ad says "Free consultation" and the landing page says "Schedule your appointment — $99 deposit required," you just destroyed trust. The visitor feels baited. This isn't just bad UX — it's the kind of thing that generates bad reviews and chargebacks.

How to check:Read every ad variation in the ad group. Then read the landing page top to bottom. Make sure every promise made in any ad variation is fulfilled on the page. Pay special attention to pricing, "free" offers, guarantees, and timeframes.

Target keyword appears in the page content

Why it matters:Google evaluates landing page relevance as part of Quality Score. If the keywords you're bidding on don't appear anywhere on the page, you're going to pay more per click for the same position. Beyond Google's algorithm, visitors scan the page for the words they just searched. If they don't see those words, the page feels irrelevant.

How to check:Take the top 5 keywords by spend in the ad group. Ctrl+F each one on the landing page. They should appear naturally in the headline, body copy, or subheadings. Not stuffed — naturally. If your top keyword by spend doesn't appear on the page at all, that's a problem.

Not sending paid traffic to the homepage

Why it matters: Homepages are designed for everyone. Paid traffic is specific — someone searched for something specific and clicked an ad about that specific thing. A homepage makes them navigate, find the right service, and figure out how to act on it. Every extra click loses people. Dedicated landing pages convert 2-5x higher than homepages for paid traffic.

How to check: Look at the final URL in each ad. If it points to the root domain or a generic page, flag it. Every ad group should ideally land on a page specifically built for that keyword theme.

Section 3: Trust & Credibility

A paid visitor has zero existing relationship with the business. They saw an ad, clicked it, and now they're on a page from a company they've never heard of. The page has about 3-5 seconds to establish enough trust that the visitor doesn't bounce. These elements make or break that window.

Reviews or testimonials visible above the fold

Why it matters:Social proof is the fastest way to build trust with a stranger. A testimonial from a real customer, a Google review rating, or a "200+ five-star reviews" badge tells the visitor that other people have trusted this business and been happy with the result. Without it, the visitor has to take the business's word for everything — and they won't.

How to check:Load the page on mobile. Without scrolling, can you see any form of social proof? A review widget, a testimonial quote, a star rating, a client count? If you have to scroll to find proof that anyone has ever used this business, it's too late — most visitors won't get that far.

Trust badges and certifications

Why it matters:BBB accreditation, industry licenses, insurance badges, Google Partner status, manufacturer certifications — these add legitimacy that copy alone cannot. They're especially important in industries where licensing matters (HVAC, electrical, legal, medical).

How to check:Ask the client what certifications, licenses, and memberships they have. Then check if those are displayed on the landing page. If the client is a licensed contractor but the page doesn't mention it, that's a missed trust signal.

Real photos instead of stock images

Why it matters:Visitors can spot stock photos instantly. A stock photo of a smiling person in a headset says "this business doesn't have real imagery." Real photos of the team, the office, completed projects, or actual customers create authenticity that stock photography cannot replicate.

How to check: Right-click any hero image on the page and do a reverse image search. If it shows up on stock photo sites, flag it. Every landing page should have at least one real photo — ideally of the team, the work, or the actual business location.

Contact information visible

Why it matters: A phone number, physical address, and email on the page tell the visitor this is a real business with real humans behind it. Hiding contact info makes the page feel like a lead-gen trap. For local service businesses, a visible local phone number and address are non-negotiable.

How to check: Can you find a phone number, email address, or physical address on the page without scrolling more than once? Is the phone number clickable on mobile? Is the address real (check Google Maps)?

Section 4: Conversion Elements

This is where the conversion actually happens — or doesn't. The page needs to make it stupidly easy for someone to take the next step. Every extra field, every confusing button, every hidden form is a leak in the funnel.

Primary CTA visible above the fold

Why it matters:The visitor should be able to see how to take action without scrolling. That doesn't mean the only CTA should be above the fold — repeat it throughout the page — but the first one needs to be visible immediately. If the visitor has to hunt for the form or the button, friction goes up and conversions go down.

How to check:Open the page on both desktop and mobile. Without scrolling, can you see a form, a "Call Now" button, or a clear CTA button? If the first actionable element requires any scrolling on mobile, it needs to move up.

Phone number is clickable (click-to-call)

Why it matters:On mobile, the phone number needs to be a tappable tel: link. If someone has to memorize the number, switch to their dialer, and type it in, most of them won't. For service businesses, phone calls are often the highest-intent conversion. Making the number non-clickable is leaving money on the table.

How to check:Open the page on your phone. Tap the phone number. Does it open your dialer? If it doesn't, it's not wrapped in a tel: link. Check the HTML source to confirm.

Clear, specific CTA button text

Why it matters:"Submit" is not a CTA. "Get My Free Quote" is. The button text should tell the visitor exactly what happens when they click it and reinforce the value of taking that action. Specific, benefit-driven CTA text consistently outperforms generic labels.

How to check:Read every button on the page. Does each one clearly communicate what happens next? Replace any "Submit," "Click Here," or "Send" with something that includes the benefit: "Get Your Free Estimate," "Book My Consultation," "Download the Guide."

Minimal form fields

Why it matters:Every additional form field reduces conversion rate. Name, email, phone, and one qualifying question is usually the maximum for a lead gen page. If you're asking for address, company name, revenue range, budget, timeline, and a paragraph description — you're not getting a form fill. You're administering a survey.

How to check: Count the fields on the form. If there are more than 4-5, ask whether each one is truly necessary at the point of first contact. The sales team can qualify the lead on the phone — the landing page just needs to capture the lead.

Form actually submits successfully

Why it matters:This sounds obvious. It's not. We find broken forms on approximately one in five landing pages we audit. The form plugin updated and broke something. The email notification is going to a defunct address. The CAPTCHA is too aggressive. The form works on desktop but not on mobile Safari. If you haven't personally tested the form this month, test it now.

How to check:Fill out the form yourself. On desktop and on mobile. With a real email address. Verify the submission arrives wherever it's supposed to go — CRM, email inbox, Slack notification. If the lead notification doesn't arrive within 60 seconds, something is broken.

Section 5: Mobile Experience

Yes, we already covered mobile responsiveness in the technical section. This section is different. This is about the actual experience of using the page on a phone — not just whether it renders correctly, but whether it's easy to use. There's a massive gap between "technically mobile responsive" and "actually works well on mobile."

Tap targets are large enough

Why it matters: Buttons and links need to be at least 48x48 pixels on mobile. If tap targets are too small or too close together, users hit the wrong thing — or give up trying to hit the right thing. This is especially common with navigation links, footer links, and form dropdowns.

How to check:Use Lighthouse (built into Chrome DevTools) and look for the "Tap targets are not sized appropriately" audit. Or just try using the page on your phone with your thumb. If you have to use precision finger-tip taps to navigate, the targets are too small.

Text is readable without zooming

Why it matters:If the body text is 12px on mobile, nobody is reading it. Minimum body text for mobile readability is 16px. Headlines should be proportionally larger. If the visitor has to pinch-zoom to read your value proposition, you've already lost them.

How to check:Hold your phone at normal reading distance. Can you read every line of text comfortably? Check the CSS — body text should be at least 16px on mobile viewports. Also verify that line height is at least 1.5 for body copy so text doesn't feel cramped.

No horizontal scroll

Why it matters:Horizontal scrolling on mobile is a signal that the page isn't properly responsive. It's usually caused by an element (image, table, embedded video) that's wider than the viewport. It makes the page feel broken and immediately undermines trust.

How to check: Open the page on a phone and try to scroll horizontally. If you can, inspect the page in Chrome DevTools — add a temporary * { outline: 1px solid red } rule to find the overflowing element. Common culprits: images without max-width: 100%, tables, and iframes.

Form works on mobile (all field types)

Why it matters: Dropdown menus, date pickers, file uploads, and multi-step forms are notorious for breaking on mobile browsers. The form might work perfectly on desktop Chrome and be completely unusable on mobile Safari. Since the majority of your traffic is mobile, a form that only works on desktop is a form that only works for the minority of your visitors.

How to check: Fill out the entire form on an iPhone (Safari) and an Android (Chrome). Every field. Every dropdown. Every checkbox. Submit it. Verify the submission arrives. If any part of the process is frustrating or broken on either platform, it needs to be fixed before you spend another dollar on ads.

Section 6: Tracking & Analytics

If tracking is broken, you're flying blind. You can't optimize what you can't measure, and you can't prove what's working or broken without data. Yet we find tracking issues on the majority of accounts we diagnose. It's the most overlooked part of the landing page setup.

Google Ads conversion tag fires on the conversion event

Why it matters:If the conversion tag doesn't fire, Google Ads reports zero conversions — even if leads are actually coming in. Smart Bidding strategies rely on conversion data to optimize. No conversion signal means the algorithm has nothing to learn from. Your campaigns will underperform and you won't be able to demonstrate ROI.

How to check: Install the Google Tag Assistant extension. Navigate to the landing page, fill out the form, and submit. Watch Tag Assistant to see if the conversion tag fires on submission. Also check Google Ads > Tools > Conversions — if the tag status shows "Unverified" or "No recent conversions," something is wrong.

GA4 events are configured and collecting data

Why it matters:Google Ads tells you about clicks, but GA4 tells you what happens after the click — bounce rate, scroll depth, time on page, form interactions. Without GA4 data, you can't diagnose whether the landing page is the problem or the ads are. You're guessing instead of measuring.

How to check:Open GA4 DebugView (Admin > DebugView). Navigate to the landing page with debug mode enabled. You should see page_view events firing. Submit the form and verify a lead or contact event fires. If GA4 isn't installed at all, check Google Tag Manager — the GA4 configuration tag might be paused, misfiring, or pointed at the wrong measurement ID.

Thank-you page or confirmation state exists

Why it matters:A dedicated thank-you page (a separate URL like /thank-you) is the simplest and most reliable way to track conversions. It gives you a destination URL to use for conversion tracking, makes it easy to fire tags, and confirms to the user that their submission went through. Without it, you're relying on event-based tracking that's harder to set up and more likely to break.

How to check:Submit the form. Do you land on a new URL (e.g., /thank-you)? Or does the page just show an inline "Thanks!" message? A separate thank-you page URL is strongly preferred. If the client uses an inline confirmation, make sure event-based conversion tracking is correctly implemented instead.

UTM parameters are preserved through the conversion

Why it matters:If the client's CRM or lead tracking system needs to know which campaign, ad group, or keyword generated the lead, UTM parameters need to carry through. Some form builders strip UTM parameters. Some thank-you page redirects lose them. If attribution matters — and it always does — verify the data flows end to end.

How to check:Add UTM parameters to the landing page URL manually (e.g., ?utm_source=google&utm_medium=cpc&utm_campaign=test). Submit the form. Check the CRM or inbox where leads arrive — do the UTM values show up? If not, the form needs hidden fields that capture URL parameters on page load.

How to Use This Checklist

Run through this list before you launch any new campaign. Run through it again when a campaign's conversion rate drops. Run through it when you onboard a new client. The items at the top of each section are the ones most likely to be the problem, but don't skip the rest — we've seen campaigns tank because of a single broken form field on iOS or a missing conversion tag.

When you find issues — and you will find issues — document them with screenshots. This is your evidence. If the client pushes back on spending money to fix the landing page, show them the screenshot of the form that doesn't work on mobile, the PageSpeed score of 22, or the ad headline next to the mismatched landing page headline. Data and visuals end the argument.

A disciplined landing page audit process does two things for your agency: it improves results for your clients, and it protects you from being blamed when the landing page is the bottleneck. Both of those are worth the 30 minutes it takes to run through this list.
