A company website drives sales when it reliably turns the visitors it already gets into completed purchases or qualified leads, and when you can show which pages and steps are responsible for that result. You cannot confirm this from traffic alone. The method is to define the sale, measure the path visitors take to reach it, locate where people stop, fix the highest-value friction first, and then judge each change against the same outcome.
Start by defining what counts as a sale
Before you touch the site, write down the one outcome the website is supposed to produce. For some businesses that is a completed order. For others it is a form submitted by a buyer who fits your criteria, a booked consultation, or a quote request. Digital.gov recommends setting performance goals and key performance indicators before using analytics to improve a site, and that advice applies whatever your outcome is (Digital.gov analytics guidance).
Keep one primary measure close to business value, then track the steps that lead to it. The table below shows how that usually breaks down.

|---|---|---|
| Online store | Completed purchases and revenue | Product page views, add-to-cart actions, checkout starts, checkout completions |
| Service company | Qualified leads submitted through a form or phone call | Landing-page visits, form starts, completed forms, call clicks |
| Consultancy or clinic | Booked consultations | Booking page visits, booking form starts, booking confirmations |
| Manufacturer or B2B supplier | Quote or sample requests from target accounts | Product or solution page visits, quote form starts, completed requests by account type |
Avoid treating visits as proof of sales performance. A busy site can still produce few outcomes, and a quiet one can produce a few high-value ones. Diagnostic measures explain why the primary number moves; they do not replace it.

Check measurement before you change anything
If you cannot see the outcome in your reports, every redesign decision is a guess. Work through this sequence first.
- Confirm that the outcome is recorded as a conversion in your analytics setup. Submit a test form, place a test order if your store allows it, or book a test appointment, and check that the event appears.
- Confirm that each step before the outcome is recorded, including landing-page visits, form starts, and checkout starts, so you can see where people leave.
- Check that the conversion is attributed to the traffic source you expect. A broken tag or a redirect that strips tracking can make a working channel look dead.
- Write down the date your measurement was last verified. Analytics interfaces and setup steps change, so check current instructions in the product documentation rather than relying on older guides.
Google describes Search Console as the source of organic search query and click information, while analytics tools help examine what visitors do after they arrive and which conversion paths lead to outcomes (Google analytics guidance). Use each tool for its own job. Search Console tells you how people reached you from search. Analytics tells you what happened once they did.
Find friction on the path to action
Once measurement is trustworthy, walk the path yourself on a phone and on a desktop computer. Start with the pages that sit closest to the outcome: the landing pages, the form or checkout steps, and the confirmation page. Look for these problems:
- The offer is not clear within the first screen. A visitor should be able to tell what you sell, who it is for, and what happens next.
- Navigation pulls people away from the outcome. Links to unrelated articles or category pages compete with the main call to action.
- The call to action is vague, hidden, or repeated with different wording on each page.
- Forms ask for information that is not needed at that stage, or fail with errors that do not say what to fix.
- Content shifts while the page loads, so buttons move just before someone taps them.
- Pages respond slowly after a tap or click, so the visitor wonders whether the action registered.
Treat these as hypotheses to check against your data, not as universal rules. No single button color, page layout, or conversion rate applies to every business, and the evidence available for this article does not establish one.
Check page performance with Core Web Vitals
Google’s Core Web Vitals are a set of three field metrics that describe loading speed, responsiveness, and visual stability. Google’s guidance says they are diagnostics for experience, not a guarantee of sales or search rankings. The page-experience documentation states the point directly: strong results in Search Console’s Core Web Vitals report or third-party tools do not guarantee that pages will rank at the top of Google Search, because page experience involves more than these scores (Google page-experience guidance).
Use Search Console’s Core Web Vitals report to see real-user field data for groups of similar URLs. When one specific page needs diagnosis, run a live page test in a current Google performance tool and fix the problems it reports. The three metrics, with the thresholds Google listed for good experience, are:
LCP: how quickly the main content loads
Largest Contentful Paint measures how long the main content of a page takes to appear. Google’s target for a good experience is within 2.5 seconds. Slow loading usually comes from large unoptimized images, slow server responses, or heavy scripts that delay the main content.
INP: how quickly the page responds to input
Interaction to Next Paint measures how long the page takes to visually respond after a visitor taps, clicks, or types. Google’s target is below 200 milliseconds. It matters most on forms, menus, filters, and checkout steps, where a laggy response can look like a broken button.
CLS: whether the layout stays still
Cumulative Layout Shift measures unexpected movement of visible content during loading. Google’s target is below 0.1. Common causes include images or ads without reserved space, banners that push content down, and fonts that swap in late.
Google listed these thresholds in its 2025 documentation. Check the current definitions before you set targets for your own reporting, because the documentation can change.
Two data limits matter here. Search Console reports field data only for URL groups that have enough data, so a page with little traffic may not appear at all. The report is also not a complete inventory of every page on your site. A missing page is a gap in the data, not proof that it performs well.
Make the site usable and accessible
Accessibility is part of sales performance because a visitor who cannot use a page cannot buy from it. The U.S. Department of Justice states that the Americans with Disabilities Act applies to goods and services offered online by businesses open to the public. Its web guidance gives examples such as sufficient text contrast and text cues that do not rely on color alone (DOJ web accessibility guidance). The guidance puts it this way: “A website with inaccessible features can limit the ability of people with disabilities to access a public accommodation’s goods, services, and privileges available through that website.”
In practice, check these items on your conversion pages:
- Text contrast is strong enough to read comfortably, including button labels and form hints.
- Required fields and errors are identified by text, not only by a red border or icon.
- Forms have visible labels rather than placeholder text alone.
- Every control can be reached and operated with a keyboard.
- Information such as prices, delivery times, or availability is not conveyed by color alone.
This is a practical checklist, not a legal assessment. Whether a particular company or jurisdiction has specific obligations depends on facts that a general article cannot settle, so take legal advice for your situation.
Build trust without overstating it
Reviews, testimonials, and recommendations influence purchase decisions, but they only help if they are genuine. The Federal Trade Commission’s online advertising and marketing guidance and its endorsement guides say that endorsements should reflect real customer experience, and that material connections such as affiliate relationships should be disclosed clearly and conspicuously (FTC online advertising guidance; FTC endorsement guides).
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errorsApply that in three ways. Publish only reviews you can verify came from customers. Do not present a testimonial as typical results unless you can support that. If your site earns commission from a recommended product or service, state the relationship next to the recommendation rather than in a footer.

Once you have a list of problems, rank them. Score each one on three factors: how close it sits to the outcome, how many visitors or pages it affects, and how much effort the fix requires. A broken form on your main lead page usually outranks a cosmetic issue on a blog post, even if the blog post has more visitors.
Then change one focused thing at a time where you can measure the result. If you change the headline, the form, and the page layout together, you will not know which change worked. A/B testing tools can split traffic between versions and report results against your chosen outcome. Vendors of these products, such as Convert and Zoho PageSense, describe the capabilities they offer, but those are product claims. Nothing in the available evidence establishes that a particular tool or experiment will increase any company’s sales, and a test needs enough traffic to produce a meaningful result.
Evaluate each change on the same primary outcome you defined at the start. Record the date, the change, and the result. If the number does not move, the test has told you something useful, and you can move to the next item on your list.

If sales look flat: where to look first
- Outcome numbers are missing or inconsistent. Return to measurement. Fix the conversion setup before drawing any conclusion about the site.
- Traffic is steady but outcomes are low. Compare the landing pages visitors reach with the offer they arrived for. Then check the first screen, the call to action, and the form.
- Visitors reach the form but do not finish. Look at form starts against completions, check error messages, and test the form on a phone with a keyboard.
- Performance metrics are poor on key pages. Use the Core Web Vitals report and a live page test to find the cause, starting with the metric that is furthest from its target.
- Only some pages are slow or unstable. Compare the affected URLs in the report with the pages that matter most to your outcome, and fix those first.
Sales depend on many factors outside the website, including pricing, competition, sales follow-up, and demand. The website is one part of the system, and this method tells you whether the site is doing its share.
