Product Page Checklist: 12 Checks to Run Before Your Page Goes Live, Starting With the Fact That Rules Buyers Out

Check 1: Name the one fact that could make the product wrong for someone

Start with the most important question on the list: what fact could make this product wrong for a particular buyer?

For the harness, it's fit. A harness in the wrong size either rubs or slips. So the rule-out fact is the chest measurement for each size, and how to take it.

For other products it's something else:

• A lampshade: the fitting type and the diameter of the base ring
• A knitting pattern: the skill level and the yarn weight it needs
• A bike light: which handlebar diameters the clamp fits
• A face oil: the full ingredient list, for someone with an allergy

Write your product's rule-out fact at the top of your checklist. Then find where it sits on the page.

It belongs close to the option picker and the button, not in a size guide behind a link at the bottom.

The second rule-out fact is usually a limit of use

Many products have a second fact that rules people out: what the product isn't for.

Fieldmark's harness is designed for dogs who walk calmly on a lead. It isn't a no-pull harness, and it isn't designed to stop a dog that backs out of harnesses.

That isn't a weakness to hide. It's a fact that sends the wrong buyer to a better product and saves a return.

So the page says it plainly, near the size guide: "A walking harness for everyday walks. Not designed as a no-pull or escape-resistant harness."

Check 2: Build a dated fact sheet before you judge the page

You can't check a page without something to check it against. So write the facts in one place first, with where each one came from.

For the harness:

Every fact on the page should trace back to a row here. If a row's source is "I think", it isn't ready yet.

Make sure each fact can only be read one way

"Chest girth" sounds clear until you ask where to measure. Around the widest part of the ribcage? Just behind the front legs?

For this harness, it's the deepest part of the chest, just behind the front legs. That detail turns a number into a measurement an owner can actually take with a tape measure.

Look for the same problem in your own facts. "Size" could mean inside or outside. "Set of four" could mean four colours or four of one. "Capacity" could mean to the brim or to a sensible fill line. Add the detail that removes the doubt.

Check 3: Read the top of the page as words only

Take a screenshot of the top of your product page, then cover the photo with a sticky note. Read only the words.

Could someone tell:

• What the product is?
• Which version is selected?
• What it costs?
• What arrives?
• What to do next?

Fieldmark's top of page, as words only, read: "The Trailhead. €39. Moss. Add to basket."

"The Trailhead" could be a jacket, a backpack or a walking boot. The photo was doing all the explaining. Anyone whose images loaded slowly, or who used a screen reader, got almost nothing.

After the fix: "Trailhead padded dog walking harness. €39. Size: M (chest 58–72 cm). Colour: Moss. Add to basket."

The photo still helps. It just isn't the only thing saying what the product is.

Check 4: Separate the options that change suitability from the options that change looks

Not every option carries the same risk. Sort yours into two groups.

Options that change suitability: size, fit, capacity, compatibility, strength, scent for someone sensitive. Pick wrong and the product doesn't work for you.

Options that change looks: colour, finish, pattern. Pick wrong and you're mildly disappointed, but the product still works.

On the harness, size is suitability and colour is looks. Yet the page gave them equal weight: big colour swatches at the top, and a plain dropdown below reading "XS, S, M, L".

The fix puts size first, with the chest range shown inside each option ("M: chest 58–72 cm") and a "How to measure" link right beside it. Colour comes second.

If your options are hard to compare at a glance, a small table helps. There's a free variant comparison table builder on this site that drafts one in your browser from your own facts.

Check 5: Take the least obvious option all the way to the basket

The default option is the one you've looked at a hundred times. The problems hide in the others.

Pick the option most likely to go wrong. For the harness, that's XS in Rust: the smallest size, in the colour added last, photographed on a different day.

Select it and check:

• Does the main photo change to Rust?
• Does the size label update?
• Is the price still right?
• Does the stock message make sense?
• Does the basket line say "XS, Rust", not the default?

Fieldmark found two problems. The Rust photos showed size M on a large dog, which made the XS look enormous. And the basket line read "Trailhead – Moss / XS", because Rust had been added without linking it properly to its images and label.

Both small. Both would have produced confused messages from owners of very small dogs.

Check 6: Match each buyer question to the proof that actually answers it

Different questions need different kinds of evidence. A photo is good at some and useless at others.

• How big is it? Needs measurements in text, plus a photo with something for scale.
• Will it fit my dog? Needs the measuring method, the range for each size, and advice for dogs between sizes.
• What's it made of? Needs the materials named in words. A photo shows texture, not composition.
• How does it fasten? Needs a close-up of the buckles.
• How does it look on a dog? Needs a photo on a real dog, with the dog's chest measurement and the size worn in the caption.

That last one is worth copying for any product worn or used by a body. "Bramble is a cocker spaniel with a 62 cm chest, wearing size M" turns a nice photo into a usable reference.

Make a three-column table for your product: the question, the proof, and where on the page the proof sits. Any row where the proof is "the lifestyle photo" needs a second look.

Check 7: Look for anything in your photos that isn't for sale

Photos sell things you don't sell.

The spaniel photo shows a lead clipped to the D-ring. The lead isn't included. Another photo shows the harness folded beside a bag of treats and a water bottle with a logo on it. Neither comes in the parcel.

Go through every photo and list every object in it. For each one, ask: does this arrive?

If not, remove it from the photo or label it in the caption: "Lead not included." Then add a short line near the button: "In the parcel: one harness. Lead not included."

It takes ten minutes and prevents one of the most common disappointed messages in small-shop selling: "I thought it came with..."

Check 8: Put each limit beside the decision it affects

Every product has limits. The checklist question is where they sit.

A limit belongs next to the choice it changes:

• "Between sizes? Choose the larger size and tighten the straps." Beside the size picker.
• "Not a no-pull harness." Beside the size guide, before anyone commits.
• "Colours can look slightly different in daylight." Beside the colour swatches.
• "Hand wash only." In the care section, and in the product details if buyers of this kind of product usually expect machine washing.

A limit buried in a returns policy or a footer isn't really visible. Buyers find it after the decision, which is exactly when it stops being useful.

Check 9: Make exchanges clear for the decision most likely to go wrong

For anything sold in sizes, the exchange policy is part of the buying decision. People choose more confidently when they know a wrong guess can be fixed.

For the harness, a buyer wants to know:

• Can I swap it for another size?
• Does it need to be unworn, and what counts as worn? (A quick try-on indoors is usually fine. A muddy walk isn't.)
• Who pays postage for the exchange?
• How long do I have?

Put a one-line summary beside the size picker: "Wrong size? Exchange unworn harnesses within 30 days." Link to the full policy.

Then check the full policy says the same thing. If the page says 30 days and the policy page still says 14 from an older version, you've made two promises, and customers will hold you to whichever suits them.

Consumer rights on returns vary by country and by how you sell, so check current guidance if you're unsure what you're required to offer.

Check 10: Read the page aloud to someone who can't see it

This is one of the most revealing checks, and it takes five minutes.

Ring a friend. Read your product page to them, top to bottom, exactly as written. Don't add anything and don't explain.

Then ask:

• What is it?
• Which size would you order for your dog (or whatever the product is for)?
• What arrives in the parcel?
• When would it get to you?

Reading aloud strips away the layout, the photos and your own knowledge of the product. What's left is what the words actually say.

Fieldmark's friend, hearing the original page, said, "It's a harness, I think, and it comes with a lead?" The lead came from a line in the description, "clip on your lead and you're off", which sounded as if a lead was part of the deal.

You'll also hear things you never notice reading silently: a sentence that runs on, a size range in the wrong unit, a promise that sounds bigger out loud than it looked on screen.

Check 11: Follow the order past the page and into the confirmation

A product page isn't the end of the decision. The basket, checkout and confirmation email all need to agree with it.

Use your shop's test mode or test payment option if it has one. Don't place a real order just to finish a checklist.

Check:

• The basket shows the exact option and quantity
• The delivery cost appears before payment, not as a surprise
• The order summary still shows the right size and colour
• The confirmation email names the size clearly
• The confirmation mentions the exchange route, because a sized product is exactly where people need it

Fieldmark's confirmation email showed a photo of the default product, Moss in M, whatever was ordered. A customer who ordered Rust XS got an email showing something else.

They changed the template to show the ordered option's name in text and dropped the image.

If there's a step you can't safely test, mark it "not checked". An honest gap in a checklist is better than a tick you didn't earn.

Check 12: Compare the page with the packing bench

The last check happens where you pack orders.

Lay out one real parcel exactly as it goes to a customer: the product, the packaging and any card or leaflet. Then read the page line by line beside it.

Would the person who packs your orders agree with every sentence?

For the harness: one harness, a care card and a small paper bag. No lead, no treats, no water bottle. The page now says the same.

If anything on the page doesn't match the bench, either the page or the bench is wrong. Decide which, and fix it.

This check catches things no screen can: a care card that says "machine wash cool" while the page says "hand wash", a bag that changed last month, a leaflet that mentions a size you no longer make.

What one full pass of the checklist found on the harness page

Here's the Fieldmark harness after one pass through all twelve checks:

Twelve checks, and every one found something. That's normal on a first pass, and it's why the checks are worth doing before launch rather than after the messages start.

Rerun only the checks a change touches

A checklist isn't a one-off. Products change, and each change can break a fact you already checked.

You don't need to rerun all twelve every time. Rerun the checks the change touches:

• A supplier changes a part, like the buckles: checks 2, 6 and 12
• You add a size or colour: checks 4 and 5
• You reshoot the photos: checks 6 and 7
• Your exchange or delivery terms change: checks 9 and 11

Write the date beside each rerun. Over time, your checklist becomes a record of what was checked, when, and why.

What a checklist can't do

A checklist shows that the page answers the important questions honestly. It can't prove people want the product, and it can't promise more sales.

It also isn't a substitute for proper advice on product safety, consumer law or accessibility. If you're unsure about any of those for your product, check current guidance from a reliable source.

What it does do is stop you sending people to a page that makes them guess.

Your next step this week

Pick one product. Write down the one fact that could make it wrong for someone.

Then find that fact on the live page. Is it beside the option picker and the button, or hidden behind a link?

If it's hidden, move it up. Then take the least obvious option all the way to the basket and read the basket line carefully.

That's checks 1 and 5 done, and they're the two that catch the most expensive mistakes.

What Buyers Should See First on a Product Page: What It Is, Which Version, the Price and the Next Step, Before Any Story

A new visitor decides in a couple of seconds whether your page is worth scrolling. The top of the page doesn't need to say everything. It needs to say what the product is in ordinary words, which version is selected, what it costs, what to do next, and the one condition that could change the decision.

Shipping Information on Product Pages: Show Preparation Time, Delivery Time and Cost Beside the Buy Button, Not at Checkout

Delivery isn't a policy buried in your footer. It's part of what you're selling. Show how long you take to prepare an order, how long the courier takes and how the charge works right beside the buy button, and keep products that ship differently from sharing one misleading line.
