Audit Your Product Page SEO in 5 Minutes (Free Prompt)

Most Shopify product pages are invisible to Google. The meta title is just the product name. The description is three bullet points. There is no FAQ, no long-tail content, and the schema markup is whatever your theme generates by default.

I built a full PDP SEO Optimizer that does a 12-factor audit with live keyword data, schema generation, and cannibalization checks. But you do not need all 12 factors to find the biggest problems. You need 8.

Here is the exact prompt I use for a quick product page SEO audit. Copy it, paste it into ChatGPT or Claude, swap in your product details, and you will have a prioritized list of fixes in under 5 minutes.

The Prompt

Copy everything below. Replace the bracketed sections with your actual product info.

You are an ecommerce SEO specialist auditing a Shopify product page. Analyze the following product page and score it across 8 SEO factors. Be specific and actionable - do not give generic advice.

PRODUCT PAGE DETAILS:
- Product name: [e.g., "Magnesium Glycinate Complex"]
- Product URL: [e.g., "yourstore.com/products/magnesium-glycinate"]
- Current meta title: [copy from browser tab or Shopify admin]
- Current meta description: [copy from Shopify admin]
- Product description: [paste the full product description text]
- Price: [e.g., "$39.99"]
- Number of product images: [e.g., "6"]
- Image alt text (for first 3 images): [paste or write "none set"]
- Number of customer reviews: [e.g., "147"]
- Collections this product appears in: [e.g., "Sleep Support, Best Sellers"]

TARGET KEYWORD: [the main keyword a buyer would search before purchasing this product, e.g., "best magnesium for sleep"]

AUDIT THESE 8 FACTORS:

1. META TITLE - Is it under 60 characters? Does it include the target keyword? Does it have a differentiator beyond just the product name?

2. META DESCRIPTION - Is it 150-160 characters? Does it include the target keyword? Does it give a reason to click (benefit, proof point, or offer)?

3. PRODUCT DESCRIPTION LENGTH - Is there at least 300 words of content? (Most Shopify PDPs have under 100 words - this kills rankings.) Does it include the target keyword naturally in the first 100 words?

4. HEADING STRUCTURE - Does the page use the product name as an H1? Are there H2s breaking up the description into scannable sections?

5. IMAGE ALT TEXT - Do the product images have descriptive, keyword-relevant alt text? (Not "IMG_4392.jpg" and not keyword-stuffed "best magnesium supplement magnesium for sleep buy magnesium".)

6. FAQ CONTENT - Does the page have an FAQ section answering common buyer questions? (These target People Also Ask results and give Google more content to index.)

7. INTERNAL LINKS - Does the product page link to its parent collection? To related products? To any blog content? (Internal links help Google understand page relationships and pass authority.)

8. SCHEMA MARKUP - Does the page have Product schema with price, availability, and reviews? (Check by pasting the URL into Google's Rich Results Test at search.google.com/test/rich-results.)

FOR EACH FACTOR, PROVIDE:
- Score: RED (broken/missing), YELLOW (exists but needs improvement), GREEN (good)
- Current state: What you see
- Specific fix: Exactly what to change (write the improved version where applicable)
- Priority: HIGH / MEDIUM / LOW based on ranking impact

After scoring all 8 factors, give me:
- Overall score (X/8 green)
- The #1 fix I should make today (the one with the highest ranking impact for the least effort)
- 3 target keywords I should also consider for this product (based on buyer intent, not brand terms)

What You Will Get Back

A scored audit that looks something like this (from a real supplement brand I ran this on):

Factor	Score	Issue
Meta Title	YELLOW	"Magnesium Glycinate Complex" - no keyword, no differentiator
Meta Description	RED	Auto-generated by Shopify, 78 characters, no keyword
Description Length	RED	47 words. Google has almost nothing to index
Heading Structure	YELLOW	H1 exists but no H2 subsections
Image Alt Text	RED	All 6 images have default filenames
FAQ Content	RED	None
Internal Links	YELLOW	Links to collection but not to related products or blog
Schema Markup	YELLOW	Basic Product schema from theme, no review aggregate

Overall: 0/8 green. And this was a product doing $40K/month in revenue. The SEO audit took 4 minutes. The first fix (rewriting the meta description) took 2 minutes and improved click-through rate by 18% over the next 6 weeks.

Three Things This Prompt Will Not Catch

This is a quick audit. It is good for finding the obvious problems, and on most Shopify stores, the obvious problems are responsible for 80% of lost organic traffic. But it has limits:

1. Keyword cannibalization. If your product page and your collection page are both targeting "magnesium for sleep," they are competing against each other in Google. This prompt does not check your other pages. The full PDP SEO skill runs a cannibalization report across your entire site.

2. AI shopping agent optimization. ChatGPT Shopping, Perplexity, and Google AI Overviews are now recommending products based on what they can read from your product pages. They pull the first ~6,000 characters of your description. If your key product info is buried below fold or locked in images, AI agents skip you entirely. The full skill front-loads your extended description specifically for AI discovery.

3. Live keyword data. This prompt asks the AI to suggest keywords, but it is working from training data, not live search volume. The full skill connects to Keywords Everywhere or Ahrefs for real volume, CPC, and competition scores so you target keywords people are actually searching.

How to Run This on Your Top 5 Pages

Do not audit your entire catalog. Start with the 5 product pages that get the most traffic and the most revenue. Those are the pages where SEO improvements translate directly into money.

Find them in Google Analytics: Engagement > Pages and screens > filter by "/products/". Sort by sessions or revenue. Those are your top 5.

Run the prompt once per product. Fix the RED items first - they are the quick wins. Most stores can fix meta descriptions, alt text, and description length in an afternoon without touching any code.

If you want to go deeper - schema markup, FAQ generation, keyword research, internal linking maps, and AI agent optimization for every product page - that is what the PDP SEO Optimizer in the DTC Stack does. It runs a 12-factor audit with live keyword data and generates everything ready to paste into Shopify.

But start here. Five minutes, one prompt, your worst product page. You will be surprised what you find.

FAQ

Does this work with ChatGPT or Claude?

Both. The prompt is designed to work with any major AI model. Claude tends to give more structured output with clearer prioritization. ChatGPT tends to write longer explanations. Either will catch the same issues. Use whichever you already have open.

What if I do not know my target keyword?

Think about what someone would search right before buying your product. Not your brand name - the problem they are trying to solve or the product category they are shopping. "Best magnesium for sleep" not "BrandName Magnesium." If you are unsure, search your product type in Google and look at the autocomplete suggestions. Those are real searches.

How often should I audit my product pages?

Audit your top 10 pages once per quarter. Audit any page when you rewrite the copy, change the price, or notice a ranking drop in Google Search Console. For new product launches, run the audit before you publish the page - it takes 5 minutes and prevents the most common SEO mistakes from going live.

Will fixing these issues guarantee higher rankings?

No. SEO is not a single lever. But fixing RED items - especially meta descriptions, description length, and alt text - removes the barriers that prevent Google from ranking you. Think of it as clearing the path. You still need good content, relevant backlinks, and a site that loads fast. But most Shopify stores have not even cleared the path yet.
