Your Shopify Product Descriptions Are Written for You, Not Your Customer — Here’s How to Fix That

A parent is searching for a birthday costume at 11pm. They type “Elsa toddler costume” into Google. Your page shows up. And this is what they find:

“Product includes: One dress. Size: Toddler — Medium (3T-4T).”

That’s the entire description. Two lines. What’s missing isn’t the right keywords, or the right word count, or the right format. What’s missing is any reason a parent searching for a birthday costume would choose this product over the twelve others showing up in the same search.

This is the most common product description problem across Shopify stores — and it has nothing to do with SEO technique. It’s about writing for the seller instead of the buyer. The fix isn’t complicated, but it requires knowing what you’re actually getting wrong.

Most Shopify product descriptions are a spec list — not a reason to buy

Three patterns show up in store audits more than any others.

Specs without experience. The description tells you what’s in the box — one dress, size 3T-4T — but nothing about the occasion it was made for, how it’ll make a child feel, or why a parent browsing party costumes at 11pm should pick this one. Specs are table stakes. They’re not a reason to buy.

Owner language. “We are proud to offer…” “Our products are designed with…” “We believe in quality…” These phrases tell you a lot about the seller’s self-image and nothing about the buyer’s problem. Customers are searching for themselves, not you.

No structure. A wall of dense text, or two sentences and nothing else. No subheadings. No natural break between what the product is and why it’s worth having. No signal to Google about what the description covers.

None of these are malicious. They’re what happens when someone writes a product description from memory — they know what they sell, so they write what they know. The result is content that communicates to the owner perfectly and to the customer barely at all.

A product description has one job: to help the customer decide to buy. Not to document what’s in the box. Not to remind yourself what you’re selling. Plug In AI rewrites descriptions to customer-first language — in bulk or one product at a time.

Shopify’s product editor gives you a blank box — and no guidance on what to put in it

Open a product in Shopify admin. The description field is a blank rich-text editor. No word count. No keyword prompts. No heading structure. No warning if you type two sentences and publish it. Shopify accepts whatever you give it and shows it to the world.

This is why the patterns above are so common — Shopify gives merchants every tool to publish product pages and no guidance on what makes a good one.

Here’s what Google sees when it crawls those pages:

No target keywords. If your product description for a children’s costume doesn’t include the term “toddler birthday costume,” Google has nothing to match against a search for that phrase. The page exists. It just doesn’t rank. Plug In SEO’s scanner specifically flags this as a missing keyword issue — it’s one of the three most common description problems the app detects across Shopify stores.

Thin content. Pages with fewer than 300 words are a low-value signal to Google. The page can still rank — but it’s working against itself. More substantive content gives Google more to understand and more reason to consider the page relevant.

No heading structure. H2 subheadings tell Google what topics a page covers. A product description with two lines and no headings tells Google exactly nothing beyond the product title.

The result: a page that’s indexed, technically accessible, and invisible in search. It exists. It just doesn’t compete.

Three changes that turn a spec list into a description that ranks and converts

If you want to skip the manual process, Plug In SEO handles the keyword research for individual products and Plug In AI generates descriptions in bulk. Here’s what each step involves.

Step 1: Find the right keywords before you write anything

Writing a great description for a term no one searches for is wasted effort. Keyword research tells you what your customers actually type into Google when they’re looking for what you sell — and that changes the description you write.

For the costume example: “toddler Elsa dress,” “Frozen birthday costume 3T,” “princess costume toddler girl” are all terms parents actually search. None of them appear in “Product includes: One dress. Size: Toddler — Medium.”

With Plug In SEO (Keyword Studio): Open the product in Keyword Studio. There are three ways to add keywords: generate new keyword ideas, auto-research (pulls data from Google Search Console and the web), or expert mode (add any keyword manually). Once you’ve added your keywords, select them and click “incorporate keywords.” A modal appears showing the AI’s suggested edits and its reasoning. Review, approve, save.

With Plug In AI: Set a target keyword on the individual product, or add keyword instructions in the special instructions field. In bulk mode, apply the same target keywords and instructions across your entire catalog at once. If no keyword is set, the app defaults to the product title — which is a usable starting point, but not as precise as a researched term.

Step 2: Write for the customer’s experience, not the spec sheet

Specs belong in the description — sizing, what’s included, materials. But they’re not the opening. The opening is the experience.

Before:
“Product includes: One dress. Size: Toddler — Medium (3T-4T).”

After:
Make her birthday unforgettable with this Elsa Toddler Classic dress — the iconic Frozen princess look for little girls aged 3–4. Whether it’s a birthday party, a school play, or just a Tuesday when she insists on being Elsa, this character costume delivers the full princess look from the first shimmer to the flowing skirt.

Designed for all-day wear, the lightweight fabric keeps her comfortable from the party to the car ride home. Sized for toddlers aged 3–4 (height 37–41 inches). Includes one Elsa dress.

The second version is 90 words. It still contains the sizing information. But it opens with the occasion, names the character naturally (which is what parents search for), and gives the buyer an image of their child wearing it. The keywords appear once each, naturally, because they’re part of describing the product accurately.

The rule is simple: keywords placed naturally, once or twice. If inserting a keyword makes the sentence read awkwardly, rewrite the sentence. Don’t force the keyword in — write the sentence so the keyword belongs there.

Step 3: Add structure — 250–300 words and 2–3 H2 subheadings

A complete product description targets 250–300 words minimum. That’s not a filler exercise — at 300 words, you have enough space to cover the occasion, the features, the sizing, and the purchase decision without padding. Under 100 words is a critical content issue; under 300 words triggers a warning in Plug In SEO’s scanner. Above 300 is where pages can start to compete.

H2 subheadings break the description into scannable sections and give Google topical signals beyond the product title. For a costume page, natural H2s might be “Why kids love this costume,” “Sizing and what’s included,” and “Perfect for birthdays and dress-up days.” Each one is a section heading that’s also a keyword phrase.

For AEO — getting your pages cited in AI search answers — add a short FAQ block at the end of the product description. Two or three questions parents actually ask: “Is this machine washable?”, “What age does size 3T-4T fit?”, “Can I use this for Halloween?” Answer each in two sentences. AI engines scan for exactly this format when composing answers to queries.
