What shoppers ask before they buy: the pre-purchase questions to answer on your product pages
When a shopper sends a question from a product page, they've already done the hard part: they found something they want. One detail is stopping them. If the page answers it, they buy. If it doesn't, they ask, and if nobody replies soon, many of them leave.
Pre-purchase questions repeat across almost every store. They come from the same few gaps: fit, delivery, returns, stock, what the product is made of or works with, and whether the store can be trusted. This guide takes each one, explains why shoppers ask it even when the information exists somewhere on your site, and gives a fix you can make on the product page itself. For the wider picture of how to find your own question patterns, see what shoppers ask before they buy.
First, find your own questions
Before changing anything, spend an hour with your inbox. Export the last month of chat and email, and tag each pre-purchase message with a type: sizing, shipping, returns, stock, materials, compatibility, trust or other. A spreadsheet is enough. Then note which product each message was about.
You'll usually see two patterns. A few question types make up most of the messages, and a few products produce most of the questions. Start with the busiest product and the most common question. That's where a single fix on the page removes the most messages.
1. Sizing and fit: "Which size should I get?"
Why they ask: a size chart gives measurements, but shoppers want to know about themselves. "I'm 5'6" and usually a medium, will this be tight?" A chart can't answer that, so they ask.
The fix: add a short fit note right next to the size selector: "Runs small, size up if you're between sizes" or "Relaxed fit, most people take their usual size". If you know how your sizing compares to a well-known brand, add that line too. Use your return reasons to decide which products need it first: a product with many "too small" returns needs a clearer note. Finally, put one line about exchanges beside the selector, because a shopper who knows exchanges are easy is more willing to pick a size. Our guide to answering sizing questions on Shopify covers this in more detail.
2. Shipping time and cost: "When will it arrive, and how much is shipping?"
Why they ask: shipping details usually live on a separate page, and the shopper wants them in the moment of deciding. Surprise shipping costs at checkout are a common reason to abandon a cart, and an unknown delivery date is a reason not to start one.
The fix: show a delivery estimate and the shipping cost, or your free shipping threshold, near the add-to-cart button. State processing time and carrier time separately: "Ships in 1 to 2 business days, then 3 to 5 days with the carrier." If you ship internationally, say which countries and roughly how long. Before holidays, add the last order date for delivery in time. If your shipping has many rules, a short summary on the page with a link to the full table is better than nothing on the page at all.
3. Returns: "What if it doesn't work out?"
Why they ask: returns are a risk question. A shopper who isn't sure about a product wants to know the cost of being wrong. If the answer is hidden in a long policy, they ask instead, or don't buy.
The fix: add one line on the product page that answers the four things shoppers want to know: how many days, whether it's free, whether exchanges are possible and whether this item has any exceptions. "30-day returns, free exchanges, final sale items excluded" fits under the price. Link to the full policy for details. If a product can't be returned, for example personalized or hygiene items, say so on that product's page so nobody finds out after paying.
4. Stock and restock: "Is this coming back?"
Why they ask: a sold-out size or color doesn't tell the shopper whether to wait or look elsewhere. Without an answer, they often go elsewhere.
The fix: for items you plan to restock, say so on the page, with an expected time if you know it, and offer a back-in-stock notification so the shopper can leave their email instead of a message. For items that won't return, say that too, and point to the closest alternative in your range. If you sell made-to-order products, replace "in stock" with the production time, so "available" means something specific. Only promise dates you can keep: a missed restock date creates more messages than no date.
5. Materials and compatibility: "What is it made of?" and "Will it fit mine?"
Why they ask: materials matter for allergies, care, feel and values. Compatibility matters for anything that works with something else: a case and a phone model, a refill and a bottle, a part and a machine. Product descriptions often focus on benefits and leave out the specific detail the shopper needs.
The fix: add a short specifications block to every product page with the facts shoppers check: materials and percentages, dimensions and weight, care instructions, and for compatible products, an explicit list of the models it works with and the ones it doesn't. Shopify metafields are a good place to keep these consistent across your catalog. Write "Fits model A and B, not model C" rather than "fits most models". The negative answer prevents as many questions, and returns, as the positive one.
6. Trust: "Is this store real, and will someone help me if something goes wrong?"
Why they ask: new shoppers, especially those who found you through an ad or a sale, don't know you yet. Some send a small question just to see whether a person replies.
The fix: make the basics easy to find from the product page: real contact details, your reply hours, your returns line, and reviews if you collect them. Show who is behind the store on your About page. Make the checkout and payment options visible. And answer the questions that do come in quickly and in a human voice, because the reply itself is a trust signal.
A quick audit table
Use this to check one product page at a time. If a row is missing, that's the next fix.
| Question | Where the answer should be | Quick check |
|---|---|---|
| Which size? | Fit note by the size selector | Is there a sentence, not only a chart? |
| When will it arrive? | Near the add-to-cart button | Are processing and carrier times both shown? |
| What if it doesn't work out? | One line under the price | Are days, cost and exceptions clear? |
| Is it coming back? | On the sold-out variant | Is there a restock note or alternative? |
| What is it made of, will it fit? | Specifications block | Are compatible and incompatible models listed? |
| Can I trust this store? | Linked from the product page | Can a shopper find contact details and reply hours? |
What pages can't do
No product page answers everything. Shoppers combine questions in ways a page can't predict: "I'm between sizes, I need it by Friday, and can I exchange it if it's wrong?" Those still need an answer, and they often arrive in the evening.
You have a few options. A shared inbox with saved replies works if someone can check it regularly. A live chat works when someone is online. An AI chat agent can answer around the clock, but only if it answers from your own product pages and policies, says when it doesn't know, and hands the conversation to a person with the full history. Whichever you use, keep the page fixes first: every answer on the page is a question nobody has to answer at all.
Keep the loop going
Repeat the inbox review once a month, and always after a busy period like Black Friday. New products bring new questions, and policies change. Each time, fix the page where the question started. If you're preparing for the holiday rush, the Black Friday customer support checklist covers the support side.
FAQ
What are pre-purchase questions? Questions a shopper asks before buying, usually about fit, delivery, returns, stock, materials, compatibility or whether the store is trustworthy. They signal intent to buy, so answering them quickly matters.
Where should I put shipping information on a product page? Near the add-to-cart button: a delivery estimate, the shipping cost or free shipping threshold, and a link to the full shipping page.
Should my product pages have an FAQ section? A short one helps for products that get the same questions repeatedly, but put the most important answers, such as fit and delivery, next to the size selector and the add-to-cart button, where shoppers decide.
How do I know which questions my shoppers ask? Export a month of chat and email, tag each message by type and product, and count. Two or three types usually account for most of the messages.
