Landing Page Checklist for New Sellers

Running ads to a weak landing page is one of the most expensive mistakes in e-commerce. Every visitor who arrives and leaves without buying is ad money spent for nothing. Fixing the page before running ads is not an optimization — it is a precondition.

This guide is a checklist. It covers the twenty items that consistently matter most, organized in the order that matters. Each item is a small thing on its own. Combined, they determine whether a landing page converts or not.

What a landing page is and what it isn't

A landing page is a single page designed to convert one action. It is not a homepage, it is not a category page, and it is not a storefront. It exists to take a visitor from arriving to doing one specific thing — usually buying, signing up, or submitting an enquiry.

Because of that, landing pages have rules that do not apply elsewhere:

• One audience, not many
• One offer, not a range
• One primary CTA, repeated
• No navigation menu that lets visitors wander away
• Every element answers the question: "does this help the visitor convert?"

When a landing page tries to do more than one thing, it usually does none of them well.

The 20-point checklist

Above the fold

• Clear headline that states what the product is and who it's for. A visitor should know within three seconds whether this page is relevant.
• One-line subheadline that adds the key benefit. Not a paragraph. Not a mission statement. One line.
• Primary CTA visible without scrolling. On mobile especially, the buy or signup button must appear in the first screen.
• Hero image that shows the product clearly. The main visual should show what is being sold, not a stock scene of a person laughing.
• Price or price range visible. If price is hidden until checkout, most visitors will not bother checking out.

Trust

• Reviews, ratings, or testimonials. Real customer quotes. Even three of them help.
• Proof signals if no reviews exist. Sourcing details, process photos, materials, warranty terms — anything verifiable.
• Return and shipping policy stated plainly. Short, direct, near the buy button.
• Secure payment badge or processor name. "Secure checkout powered by [processor]" reduces hesitation.
• Contact method visible. Email or contact form. Hiding it suggests there's something to hide.

Content

• Bullet points for key features. Buyers scan. Long paragraphs get skipped.
• Specs or dimensions listed clearly. Materials, sizes, weights. The details buyers need to feel confident.
• FAQ section answering the top 5 objections. What it costs, how long it takes, how it's made, what if it's wrong, how to return it.
• Consistent branding — colors, fonts, voice. A page that looks stitched together reads as untrustworthy.
• Original photography, not stock. Stock images signal a temporary or drop-shipped operation to many buyers.

Technical

• Loads in under 3 seconds on mobile. Test on a phone on cellular, not on desktop wi-fi.
• Works on the smallest common screen size. Check on a 375-pixel-wide viewport at minimum.
• Tap targets at least 44x44 pixels. Buttons need to be easy to hit with a thumb.
• HTTPS with a valid certificate. Non-negotiable. Browsers warn on insecure pages.
• Meta title, description, and OG image set. Determines how the page looks when shared or shown in search results.

Fix priority — what matters most

Not all twenty items are equally important. Here is the order most sellers find produces the largest lifts per hour invested.

If you only have time to fix three things, fix headline, speed, and CTA. Those three move the number more than the other seventeen combined.

The headline

The single most impactful element on the page is the headline. It answers the question "is this page about something I want?" If the answer is unclear in three seconds, the visitor leaves.

A headline structure that works

Avoid:

• "Welcome to [brand name]" — says nothing about the product
• "The best quality, premium, luxury product" — adjectives, not information
• Clever wordplay that requires context to understand
• Buzzwords ("revolutionary", "game-changing", "next-level")

A clear headline is not a boring headline. Clarity is a feature.

Single CTA — why it matters more than most sellers think

A landing page should have one action it is trying to drive. Not "buy or subscribe or contact us or follow on Instagram." One.

Multiple CTAs have two costs. First, they split attention — a visitor has to decide which action to take, and often decides to take none. Second, they signal that the seller doesn't know what they want from the visitor.

The CTA can appear multiple times on the page — near the top, after the reviews, and at the end. That repetition reinforces the same action. It does not split attention.

The CTA button should be a distinct color from the rest of the page and large enough to hit comfortably on mobile. If two buttons appear side by side, they compete.

Speed — the invisible conversion killer

Speed is the item most sellers underestimate. A page that loads in 5 seconds on mobile loses roughly half its visitors before the content appears. Those visitors never see the offer, never click the CTA, and never convert — but the ad click was still paid for.

What actually slows pages down:

• Unoptimized images. A hero image that is 4MB in size will slow a mobile page dramatically. Compress to 100–300KB in a modern format.
• Too many fonts. Each font file adds a round-trip to the server. Two fonts is usually one too many.
• Heavy tracking scripts. Each analytics or marketing pixel costs load time. Keep essential ones only.
• Video autoplay on load. Autoplaying hero videos consume bandwidth before anything else can load.
• Unminified CSS and JavaScript. Most modern platforms handle this automatically, but custom code often doesn't.

Run the page through a speed test on mobile settings. If it loads in under 3 seconds, it's competitive. If it takes longer, the images are almost always the first place to look.

Trust signals when you have no reviews yet

New sellers face a chicken-and-egg problem: reviews build trust, but reviews require sales, and sales need trust. The workaround is to substitute other proof until reviews accumulate.

Substitutes that work:

• Process photos. Show the product being made, packed, or handled. Real process photos signal a real operation.
• Material specifics. "Full-grain Italian leather" is more trust-building than "high quality leather" because it can be checked.
• Warranty or guarantee. A clear guarantee ("30-day returns, no questions asked") transfers risk away from the buyer.
• A short about-the-maker note. One or two sentences on who makes the product and why. Not a life story — a signal of accountability.
• Featured or mentioned badges. If you've been featured anywhere — even a small blog — that mention is social proof.

These are not equivalent to reviews. They are what to use until reviews exist.

Common mistakes

• Running ads before the page is fixed. The most expensive mistake in the list. Ads do not fix conversion — they multiply whatever the page already does.
• Hiding the price. "Contact us for pricing" or "Add to cart to see price" reduces conversion sharply for most consumer products.
• Too many CTAs. Every additional action dilutes the primary one.
• Full navigation menu on the landing page. Navigation invites visitors to leave. Remove it or reduce it to a logo.
• Mobile last. Most paid traffic is mobile. If the page is designed desktop-first, it will look and perform worse where it matters most.
• Testing multiple changes at once. If two things are changed and the numbers move, there is no way to know which change helped.

What to do next

Run the checklist on your landing page. Score it honestly. Fix the top three priority items — headline, speed, CTA — before running any ad spend.

Then run a small ad test. Measure two things: click-through rate from the ad, and conversion rate on the page. If CTR is healthy but conversion is not, the page needs more work. If CTR is weak, the ad or the audience needs adjusting.

A landing page is not a one-time project. It is a working draft that improves with each round of data. The goal is not a perfect page — it is a page that gets better every month.
