Ecommerce Copywriting: How to Write a Store That Sells

Key Takeaways

• People scan before they read: in Nielsen Norman Group research 79% of test users scanned any new page, and NN/g's 2020 review of 13 years of eyetracking found people "still primarily scan, rather than read", so every page should lead with its most useful words.
• Plain beats promotional: in a 1997 NN/g study, a version of the same site rewritten to be concise, scannable and objective measured 124% more usable than the promotional original; it measured usability, not sales.
• Each page has its own job: the homepage says what you sell and who it is for, a collection page helps people choose, and a product page answers every question standing between a visitor and the add to cart button.
• Our own data: when we improve product pages, conversion rate typically rises by about 2 percentage points for badly designed pages and by 0.5 to 1 point for average to well designed ones, and the words on the page are part of that work.
• UK rules apply to every line: CAP Code rule 3.7 says you must hold evidence for objective claims before you publish, false "today only" urgency is banned outright, and the CMA can now fine a business up to 10% of turnover or £300,000, whichever is greater, for breaking consumer law, including on prices.
• Your copy writes your search results too: Google says snippets are "primarily created from the page content itself", and that meta descriptions are cut to fit the screen rather than at a fixed character count.

Quick Answer

Ecommerce copywriting is the writing on your online store: the homepage, collection pages, product titles and descriptions, and the search titles and meta descriptions that bring people in. Good store copy is concise, scannable and specific. It leads with what the product is, who it is for and why it is worth the price, answers practical questions about size, materials, delivery and returns in plain words, and swaps boasts for facts a shopper can check. In the UK it must also follow the CAP Code and consumer law, which means holding evidence for claims, showing total prices and keeping urgency and was prices genuine.

Store copy usually fails by leaving things out rather than by bad writing. Product pages carry the supplier's description word for word, homepages open with "Welcome to our store", and most stores we work with have a good brand story that never reaches the customer. This guide covers the web copywriting rules that apply to every page, then the homepage, collection pages and product pages in turn with before and after examples, the search titles and meta descriptions that win the click, the UK rules on claims and prices, and a simple process for rewriting a store page by page.

What Ecommerce Copywriting Is and Why It Matters

Ecommerce copywriting is everything a shopper reads on the way to buying: headlines, navigation labels, collection introductions, product titles, descriptions, specifications, delivery and returns notes, and the title and description Google shows in search. Its job is not to sound clever. Its job is to help the right person decide quickly, and to give the wrong person enough information to leave without ordering something they will send back. Web copywriting is the wider skill of writing for any website, for people who scan on a screen; ecommerce copywriting applies the same rules to pages whose job is to sell, and adds product data, prices and the rules on claims.

It matters because almost nobody reads a page from top to bottom. In Nielsen Norman Group's 1997 research on how people read websites, 79% of test users always scanned a new page and only 16% read word by word; it was a small study, but the pattern has held. Jakob Nielsen's 2008 analysis of real browsing data estimated that people read about 20% of the words on an average page, 28% at most, and that each extra 100 words added only 4.4 seconds of reading time. NN/g's 2020 review of studies spanning 13 years, with over 500 participants and more than 750 hours of eyetracking, concluded that "People still primarily scan, rather than read."

The pages that sell are often the weakest. Baymard Institute's 2026 product page benchmark rated the product page experience of 52% of the desktop sites, 62% of the mobile sites and 64% of the apps it reviewed as "mediocre or worse". These are shares of large ecommerce sites benchmarked by Baymard, not of shoppers, and copy is only one part of the score, but missing or badly structured information runs through most of the problems it lists.

Web Copywriting Rules That Apply to Every Page

Some of the clearest evidence on writing for the web is old, and it still holds. In NN/g's measured study, John Morkes and Jakob Nielsen rewrote the same travel site several ways and compared each version with the promotional original. The concise version scored 58% better on their usability measure, the scannable version 47%, the objective version 27%, and the version that did all three 124%. Users in the same research "detested marketese", the boastful style with claims such as "hottest ever", and NN/g noted that credibility suffers when users can see a site exaggerates.

Five rules follow from that research and from GOV.UK's writing guidance:

• Front load everything. NN/g's 2006 eyetracking study of 232 users found an F shaped reading pattern and advised that the first two paragraphs must state the most important information, because people read the third word on a line much less often than the first two. Its 2017 update found the pattern "alive and well" on desktop and mobile. Start headings, paragraphs and bullets with the words that carry the meaning.
• Put the conclusion first. NN/g's guide to the inverted pyramid says to start with the most important piece of information and names ecommerce product descriptions as a place to use it.
• Keep paragraphs and sentences short. GOV.UK guidance says paragraphs should have no more than 5 sentences and to split up sentences over 25 words. One idea per paragraph, as NN/g puts it, because readers skip ideas that are not caught by the first few words.
• Use plain words. GOV.UK says to use "buy" instead of "purchase" and "help" instead of "assist", and its A to Z style guide lists words to avoid, including deliver, leverage, streamline, utilise, empower and robust. GOV.UK's clear language guidance also reports that 80% of people in research on legal language preferred sentences written in clear English, and that the preference grew with the complexity of the issue.
• Write facts, not boasts. Every "amazing", "premium" and "world class" is a word the shopper has to filter out. Replace each one with the detail that made you want to write it: the fabric weight, the roast date, the number of washes it survives.

Homepage Copy: Say What You Sell in the First Screen

A homepage has a few seconds to answer three questions: what do you sell, is it for me, and where do I go next. Many homepages answer none of them in the first screen. The headline is a mood ("Live beautifully"), the line under it is a welcome, and the product categories sit below a slideshow of offers.

Baymard's homepage and category navigation research rated 61% of desktop sites and 65% of mobile sites "mediocre" to "poor", and found that some category pages performed poorly in testing because they put promotional content above the navigation to subcategories. The lesson for copy is the same: lead with the words that help someone find their way, and let the promotion follow.

Before and after: a homepage headline

• Before: Welcome to our store! We are passionate about coffee and committed to bringing you the very best quality at unbeatable prices.
• After: Speciality coffee roasted to order in small batches and posted within two working days. Beans or ground, from £8 a bag, or subscribe and save 10%.

The after version says what is sold, what makes it different, what it costs and what to do next. It also drops "the very best" and "unbeatable prices", which the ASA would treat as claims against every competitor, and which the shop could not prove. Every fact in our examples is invented to show the shape; use only details that are true of your store.

Your brand story belongs on the homepage, but in proportion: one line in the first screen, a short paragraph further down with a link, and the full story on its own page. Our guide to brand storytelling for ecommerce covers how to find and write it.

Collection Page Copy That Helps People Choose

Collection pages are where people compare, so the most important copy is the information under each product, not the paragraph at the top. Baymard's product listing research found that 50% of the sites in its benchmark failed to show enough information in their product lists, "leading users to dismiss perfectly relevant products or even abandon a site". Its five essentials are the price, the product title or type, a thumbnail, the ratings average and count, and the variations available, and 35% of sites missed at least one. It also found that product titles running past three or four lines on a phone were seen as too long.

Name products the way people search and compare. A listing title that starts "The Everyday Essential You'll Love" tells a scanning shopper nothing; "Merino Crew Neck Jumper, Navy" tells them the material, the style and the colour in the first two words, which is where NN/g says the eye lands.

Filter labels are copy too. Baymard's sustainability research found 37% of sites in its benchmark used industry jargon in filter labels without explaining it, and 25% failed to highlight qualities such as recycled materials or ethical production. If customers choose your products for a reason, make that reason a filter with a plain name.

Keep collection introductions to one or two sentences above the products, so the grid starts on the first screen of a phone, and put any longer buying guide below the grid, where it helps search engines and the shoppers who scroll for it without pushing the products down.

Before and after: a collection introduction

• Before: Discover our amazing range of jumpers, perfect for every occasion. Shop now and find your new favourite!
• After: Merino and lambswool jumpers in sizes XS to 3XL, knitted in Scotland. Filter by fit, weight or colour; every jumper comes with free returns within 30 days.

Product Page Copy: Titles, Descriptions and Specifications

The product page is where copy earns its keep. In our work, when we improve product pages, conversion rate typically rises by about 2 percentage points for badly designed pages and by 0.5 to 1 point for average to well designed ones. Copy is rarely the only change, but it is usually the cheapest: rewriting a description costs far less than new photography or a new theme. Our guide to product page design covers the layout; this section covers the words.

Lead with highlights, then the detail

We recommend writing product copy in four layers, so a shopper who reads only the first lines still gets the point and one who reads everything finds every answer:

1. One sentence that says what it is and who it is for. Not a slogan; the sentence a good shop assistant would say first.
2. Three to five highlights. Each starts with a short bold phrase and adds one sentence of proof: what it does, how big it is, what it is made of.
3. The full detail. Materials or ingredients, dimensions with units, care instructions and compatibility, grouped under plain headings.
4. Delivery and returns. The cost, the time and the returns window, on the page rather than behind a link.

The last layer matters more than most shops think. Baymard's product page research found that most users look for returns information on the product page (60%), and that 15% of the US shoppers it surveyed had abandoned an order in the previous quarter because they found the returns policy unsatisfactory. The same research describes a participant who could not work out the height of a lamp from the pictures and abandoned the product rather than use the written dimensions, so put the measurements where people will see them, and say what they mean: "fits on a bedside table" next to the 38cm.

Before and after: a product description

• Before: This stunning lamp will transform any room. Crafted from the finest materials, it is the perfect addition to your home.
• After: A bedside lamp in solid oak. 38cm tall with a 25cm linen shade, so it sits below most headboards. Takes an E14 bulb up to 40W, and a warm LED bulb is included. Free UK delivery in 2 to 4 working days, and free returns within 30 days.

Specifications people can scan

Baymard's spec sheet benchmark found that 50% of sites had specification sheets that were hard to scan, 23% did not group specifications into sections, and only 3% used a short summary of the most important specifications. It also found 52% of sites did not edit the product data their suppliers sent before publishing it. Its 2026 guide rated almost two thirds (64%) of spec sheets poor or mediocre, and advises defining jargon in the page and always putting the unit of measure after the number.

Two more fixes cost nothing. First, write your own descriptions: Shopify advises against copying the manufacturer's text, which may already appear on other websites. Second, do not hide the description behind tabs. Baymard's testing found participants repeatedly overlooked content that could only be reached through horizontal tabs, a pattern 29% of sites still use; expanded or collapsed sections worked better.

SEO Titles and Meta Descriptions That Earn the Click

Your search result is the first piece of copy most shoppers see. Google says snippets are "primarily created from the page content itself" and that it may use the meta description when that describes the page better, so good page copy and a good meta description work together. Google also warns that identical or similar descriptions on every page are not helpful, suggests that a product page's description can bring together details such as price and manufacturer that are scattered through the page, and encourages generating descriptions from product data on large catalogues. Its own example turns a two word description of a mechanical pencil into one that names what it does, the lead it comes with, the colours and the free shipping threshold.

Before and after: a product meta description

• Before: Oak lamp. Buy oak lamp online. Best oak lamp UK. Shop lamps now.
• After: Solid oak bedside lamp, 38cm tall with a linen shade and a warm LED bulb included. Free UK delivery and free returns within 30 days.

On length, the guidance conflicts. Shopify's SEO help page suggests page titles of 60 characters or fewer, although the field accepts 70, and 160 characters for meta descriptions, while its product help page warns only that titles over 70 characters and descriptions over 320 might be cut off. Google says there is no limit on meta description length and that it shortens snippets to fit the device. A safe rule is a title of about 60 characters with the product type first, and a description of about 150 characters that leads with the facts, so nothing important is cut on any screen. In Shopify you edit both in the Search engine listing section of each product, collection and page.

Alt text is worth the minute it takes: it describes each image for people who cannot see it, and Shopify allows 512 characters but recommends 125 or fewer, so describe the image, not the keyword. And forget word counts: Google says it has no preferred word count, and asks instead whether content shows first hand expertise. On product pages, first hand detail is the measurement you took, the wash you tested and the question customers keep asking. That detail is also what AI assistants can quote, and some of our clients already see up to 5% of their traffic arriving from AI assistants. Our guides to Shopify SEO and generative engine optimisation go further.

The UK Rules Your Copy Has to Follow

The CAP Code, which the ASA enforces, applies to the marketing claims on your own website as well as to your ads. Rule 3.1 says marketing must not materially mislead. Rule 3.2 allows obvious exaggeration that nobody would take literally, so "a jumper you'll want to live in" is fine. Rule 3.7 is the one that catches shops: before publishing, you must hold documentary evidence for any claim a consumer would see as objective, such as waterproof, vegan or clinically tested. The ASA's advice on puffery and opinion adds that putting an objective claim in quotation marks or a testimonial does not remove the need for evidence.

Your descriptions are also part of the contract. Trading Standards' Business Companion explains that under the Consumer Rights Act 2015, goods must match the description a customer relied on, and that the description and advertising count when judging satisfactory quality. Since the Digital Markets, Competition and Consumers Act 2024 replaced the old unfair trading regulations, the related changes to the CAP Code have applied from 7 April 2025, and the CMA can fine a business up to 10% of its turnover or £300,000, whichever is greater, for breaking the law, including on prices.

Here is how the rules apply to some common lines:

Two more rules matter for product pages. CAP Code rules 3.44 to 3.46 ban fake reviews, require incentivised reviews to be labelled, and ban publishing reviews in a misleading way, such as hiding negative ones or giving positive ones more prominence. And the Green Claims Code asks that the explanation of an environmental claim sits close to it, online "by a single click through link". This is a summary of published guidance, not legal advice; the ASA's own advice pages carry the same note.

How to Rewrite Your Store Copy in Five Steps

1. Gather the customer's words. Read your reviews, support emails, returns reasons and Search Console queries. The questions customers ask are the gaps in your copy, and the words they use are the words to write in.
2. Lead with the facts. Rewrite the first sentence of every page so it says what the thing is, who it is for and, where it helps, what it costs.
3. Cut the marketese. Delete every adjective you cannot prove and replace it with the detail behind it. Then cut the page by a third and see what you miss.
4. Check every claim. Hold the evidence for objective claims, show total prices, check was prices against your price history, and make sure every green claim is specific.
5. Measure the change. Rewrite one template or one collection at a time and compare add to cart and conversion rate for the same weeks before and after, so a sale or a season does not take the credit.

Start with the pages that earn the most: your top ten products by revenue, the collection pages that get the most search traffic and the homepage. A shop with a few hundred products can do the top pages by hand and use a template for the rest, which is also where Google's advice on generating meta descriptions from product data helps.

Why Matters Perspective

Our view is that the biggest gains in store copy come from what you add, not from how you phrase it. The pages say too little about the things shoppers worry about, such as size, materials, delivery and returns, and too much about how passionate the brand is. The fix is not a cleverer headline; it is answering every question a customer would ask in a shop, in the order they would ask it.

Words work best with the pictures and the page around them. When we helped Halo Coffee with its rebrand and relaunch, Halo invested in specialist product photography and worked with the creative agency Uncommon, and conversion rate rose from 0.5% to 3% after the relaunched site went live. We write and rewrite store copy as part of our conversion rate optimisation and Shopify SEO work. We are a Shopify Select partner with Verified Skills across development and marketing, and a Klaviyo, Recharge, Awin, Meta and TikTok partner. Retainer clients are billed one month in arrears and are not tied into long contracts, and development projects carry a 3 month guarantee.

Frequently Asked Questions

What is ecommerce copywriting?

Ecommerce copywriting is the writing on an online store: the homepage, collection pages, product titles and descriptions, specifications, delivery and returns information, and the search titles and meta descriptions. Its job is to help the right shoppers decide quickly by leading with clear, specific facts rather than promotional claims.

What is the difference between web copywriting and ecommerce copywriting?

Web copywriting is writing for any website, for people who scan on a screen: front loaded, concise and plain. Ecommerce copywriting uses the same rules on pages whose job is to sell, and adds product information, prices and the UK rules on claims, such as the CAP Code and consumer law.

How long should a product description be?

Long enough to answer every question a shopper has, and no longer. Google says it has no preferred word count. Lead with one sentence on what the product is and who it is for, then three to five highlights, then the full detail on materials, size, care, delivery and returns, so scanners and careful readers both find what they need.

Should I use the manufacturer's product descriptions?

No. Shopify advises against copying text a manufacturer provides, because it may already appear on other websites. Baymard found 52% of sites published supplier data without editing it. Rewrite descriptions in your own words, add what you know first hand, and keep the supplier's specifications only after checking and grouping them.

How long should a Shopify SEO title and meta description be?

Shopify's help pages differ: one suggests titles of 60 characters or fewer and descriptions of 160, another warns only above 70 and 320. Google shortens snippets to fit the screen. A safe rule is a title of about 60 characters with the product type first and a description of about 150 characters that leads with the facts.

Can I say my product is the best?

Only with evidence, unless the claim is obvious exaggeration nobody would take literally. The ASA treats an unqualified superlative as a claim against all competing products, and usually reads No. 1 as an objective best selling claim that needs market share or unit sales evidence.

Are countdown timers and was prices allowed in the UK?

Yes, if they are genuine. The CAP Code bans falsely claiming an offer is available only for a limited time, so a timer that resets is not allowed. A was price must be a genuine usual selling price, and the ASA expects at least three months of pricing history to judge it.

Final Thoughts

Good ecommerce copy is less about style than about service. Say what the product is in the first line, answer the questions customers ask, show the price they will pay, and prove anything that sounds like a fact. Do that on your best sellers first and measure the result before rolling it out.
