Before buying more traffic, audit the page people will land on, the action you want them to take, and the evidence that action was completed. Start with five problems: broken destinations, an unclear offer, a frustrating mobile journey, slow or unstable pages, and unreliable measurement. Fix failures that stop a visitor from completing the task before spending time on cosmetic scores.
This is a pre-campaign checklist for a business owner or marketer. It is narrower than a full technical SEO audit. The goal is to answer a practical question: if a relevant person arrives today, can they understand the offer, complete the next step, and leave a record you can trust?
Choose one real journey before opening an audit tool
Write down the traffic source, exact destination URL, intended visitor, promised offer and desired action. For an ecommerce campaign, that might be a particular product page followed by checkout. For a service business, it might be a consultation page followed by a completed enquiry. For software, it might be a signup followed by the first useful action inside the product.
Use the actual campaign URL, including its tracking parameters. A homepage review will not reveal a broken product link or a form that fails on the landing page. Review one representative journey first, then repeat the check for materially different offers, templates or devices.
Keep a simple audit record with the URL, device, observed problem, evidence, owner, proposed fix and retest date. Screenshots help explain an issue, but pair them with the exact steps that produced it. A screenshot of a button does not prove the button works.
1. Broken destinations and pages that only look available
Open the destination directly, follow its internal links, and reload it. Check that the page shows the expected content rather than a login screen, generic fallback or not-found message. A server can return HTTP 200 while the visible page says the content is missing. That is why an availability check should include both the response and the rendered result.
For public pages that should appear in search, inspect the title, canonical URL, robots instructions and content in the initial HTML. Check that your sitemap lists real public pages. Keep account, checkout and other private areas out of public article inventories. A sitemap submission is a discovery aid, not proof that a page is indexed.
JavaScript sites deserve an extra check: does the important explanation appear after the page loads, and can a crawler retrieve it? Google's JavaScript SEO documentation explains its crawling and rendering process. Rendering is a separate stage, and a missing page needs an appropriate error response rather than a normal success page. Server-visible content reduces reliance on later rendering, although it does not guarantee indexing.
Retest: visit the exact repaired URL, reload it, follow a link from its parent page, and inspect the public response again. Test an intentionally missing URL too. That failure case helps reveal whether the site still turns every unknown route into a success response.
2. An offer visitors cannot explain
Read the page as someone arriving from the campaign. Can you identify what is being offered, who it is for, what it costs or how to get a price, and what happens after the main action? The page should support the promise in the ad or referral. If the campaign promotes a particular package, avoid dropping visitors onto a page that makes them search for it.
Look for decision information near the action: the product's limits, delivery or service boundaries, relevant requirements and accurate terms. Use proof you can substantiate. A clear description and a real example are more useful than a list of impressive claims with no supporting evidence.
For a service enquiry, explain which problems the service addresses and what information the prospect needs to provide. For software, explain what the user can actually do and which features require a paid plan if that distinction applies. Check the live product and current terms before making promises about access or price.
Ask someone outside the team to read the page and describe the offer in their own words. Treat this as qualitative feedback, not a conversion experiment. If several readers interpret the same sentence differently, revise it and repeat the task before launching a larger test.
Retest: compare the campaign promise with the landing page headline, supporting detail and action. Remove outdated promotions, conflicting prices and unsupported claims. A stronger headline alone will not repair unclear fulfilment terms.
3. A mobile journey that breaks at the next step
On a phone, start from the actual destination and carry out the intended action. Check navigation, text size, tap targets, form fields, validation messages and sticky elements. A banner or chat widget can cover the button visitors need. A layout can appear tidy while the keyboard makes a form difficult to complete.
Test the useful failure states. Leave a required field blank, enter an invalid email address and use the back button. A good form should explain the problem without erasing all the information the visitor already entered. Check the success state too: visitors should know whether their request was received and what happens next.
For an ecommerce journey, inspect product selection, stock messages, shipping information, discount terms and checkout handoffs. Use an authorised test environment or provider test mode when you need to complete a transaction. Do not make a real purchase simply to finish an audit without permission. If the final payment step cannot be tested, record that limit rather than marking checkout verified.
Include accessibility in the practical review. Try keyboard navigation on desktop, check whether controls have useful labels, and inspect colour contrast and zoom behaviour. The W3C Easy Checks provide a starting point. These checks can identify common issues; passing them is not a complete accessibility evaluation or a compliance certification.
Retest: repeat the same journey on a real phone after the change. Confirm that error messages and the final confirmation are understandable, not merely visible in a screenshot.
4. Slow pages and movement that interrupts the task
Run a performance check on the exact landing page and relevant templates, then watch the page load on mobile. Look for a large hero image arriving late, fonts that shift the heading, banners that push the form down, or scripts that delay interaction. Identify the element causing the problem before changing several unrelated parts of the site.
Google's Core Web Vitals guidance covers loading, responsiveness and visual stability through LCP, INP and CLS. Distinguish measurements from real users from lab diagnostics. A controlled test can help reproduce a problem; it does not describe every visitor's connection, device or session. Where real-user data is unavailable, say so and use lab findings as a starting point.
Common practical fixes include correctly sized images, reserved space for media, fewer unnecessary third-party scripts and a simpler above-the-fold layout. Check the site's actual bottleneck before applying a generic optimisation list. Removing a script can also break attribution, consent or a useful customer feature, so retest those behaviours after the change.
Do not treat an improved score as proof of increased sales. Keep performance evidence and business outcomes separate. A faster page that still makes the wrong promise or has a broken form will continue to frustrate visitors.
Retest: repeat comparable diagnostics, inspect the original visual problem, and complete the next action. Record the device and test conditions so the comparison is interpretable.
5. Measurement that counts the wrong thing
Define the business action before reviewing analytics. A click on a submit button is different from a successfully received enquiry. A visit to checkout is different from a completed order. A signup is different from an activated user. Choose the event that corresponds to the decision the campaign is supposed to influence.
Use the analytics provider's debugging tools to inspect events while testing the journey. Google's GA4 DebugView documentation explains how to view debug events and their parameters. Debug evidence helps check instrumentation; it does not prove that every production visitor is measured or that the event caused revenue.
Reconcile a small authorised sample with the underlying record, such as the enquiry in the CRM or the order in the commerce platform. Check that the event occurs once, includes the intended information and is excluded from business reporting if it is a labelled test. Document how consent, ad blockers or a cross-domain handoff can limit visibility. Do not bypass privacy choices to make a dashboard look complete.
Check campaign parameters too. A consistent naming convention helps compare sources, but parameters alone do not fix duplicate events, missing confirmations or inconsistent order values. Keep analytics, native order records and ad-platform attribution as separate evidence streams.
Retest: complete the authorised test journey, confirm the resulting record, and inspect the corresponding event. If the final action requires payment or access you do not have, leave that verification open and identify the exact step needed.
Turn the findings into a short repair queue
Prioritise a failure that prevents the action, sends visitors to the wrong place or corrupts the evidence. Next address missing decision information and reproducible mobile friction. Performance and design improvements should have a clear observed problem and a retest, rather than becoming a collection of score-chasing tasks.
As an illustrative example, suppose a service landing page has a large image, an unclear package description and a form that sometimes shows a success message without creating a CRM record. The form failure comes first because it loses the enquiry. Clarify the offer next so qualified visitors understand the service. Optimise the image while preserving the functioning journey. This example describes a prioritisation method, not a measured client result.
For each repair, name one owner and one acceptance check. “Improve mobile” is too vague. “The request form remains usable with the keyboard open, preserves values after validation and creates one test record” is reviewable. Retest the original problem before closing the task.
Findings and acceptance worksheet
Copy one row for each issue you can reproduce. Record the exact URL, device and steps, then keep evidence separate from a suspected cause. Write the acceptance check before assigning the repair so the owner knows what “fixed” means.
| URL and step | Evidence and device | Severity | Owner | Next fix | Acceptance and retest |
|---|---|---|---|---|---|
For example, a fictional landing page shows a confirmation after a test enquiry but the matching test record is absent from the receiving system. Assign the form handoff to its responsible owner, trace the request, and accept the repair only when one labelled test creates one record and the page shows an accurate confirmation. This is a practical illustration, not a customer result. Compare the broader full website audit checklist for checks across site templates, or use the conversion testing guide when the journey works and you need to evaluate a proposed change.
Your next step
Choose the landing page you are about to promote and run these five checks before increasing traffic. Keep the evidence and unresolved limits with your campaign brief. Use Smart Site Audit's public overview to understand its website-analysis workflow, then compare any automated findings with the actual visitor journey. A tool can help organise observations; the release check is still whether the page and next action work.
