How your project runs
Teams we have built for:








The Problem
It often starts after a theme update or a new review app. Two sets of markup describe the same product, and one of them is wrong.
01 · Plain links
Your best seller shows as a plain blue link in Google.
Product and Offer markup gives Google your price and stock for richer listings.
02 · Duplicate data
Google sees two conflicting copies of your product data, or none.
We merge your theme and app output into one clean set of JSON-LD.
03 · Missing stars
Your real reviews don't show as stars in search results.
AggregateRating reads your live review data, so stars match what shoppers see.
04 · Theme updates
A theme update dropped the price from your markup unnoticed.
Every template is tested before release, so markup survives the next theme update.
You search for your best seller and find a plain blue link. The competitor below shows star ratings, a price, and stock status. Your review app holds plenty of real reviews, but Google sees two conflicting copies of your product data, or none. Search Console flags missing brand and identifier fields. Last month's theme update dropped the price from your markup, and nobody noticed. The richer listing takes the click.
We start by reading what your theme and apps already output, so we fix the source instead of adding a third copy. Then we write one clean set of JSON-LD: Product and Offer for price and stock, AggregateRating from real reviews, and BreadcrumbList for categories. Every template is tested before release, so your markup survives the next theme update instead of breaking with it.
One source of markup
Your theme and app output merged into one set, so Google stops seeing duplicate or conflicting products.
Ratings from real reviews
AggregateRating reads live review data, so the stars match what shoppers see on the page.
Tested on every template
Validation checks on your products, collections, and articles before any change goes live.
Our Schema Markup Process
You see the markup plan and the test results before anything changes on your live store, and you can check each result yourself.
We read the markup your theme and apps print on sample pages, then walk you through what's duplicated or missing. If your theme already covers it, we'll tell you before we quote.
What's Included
Every plan starts with a check of your current markup. Larger plans add reviews, breadcrumbs, store policies, variants, and longer monitoring.
Compare Options
A schema app installs in minutes, and your theme's built-in markup costs nothing. Here's where each option stops when accuracy matters.

Projects We've Built
Ecommerce stores our team has designed and built. We write product templates every week, so adding clean markup to yours is familiar work.
What Our Clients Say
Feedback from teams we have built stores, templates, and search-ready product pages for.
What I appreciate most is that the website is actually easy for us to manage now. We can update content ourselves instead of sending a developer a message every time we need to change something small. They also paid attention to the technical SEO side, which mattered to us because we didn’t want a new website to create problems for the traffic we already had. I’ve probably asked more questions than I should have since launch, but every question has been handled patiently and without any fuss. The team is easy to work with, they explain things clearly, and when we need something changed, they focus on getting it done rather than making the process complicated.
Our old store was making it way too difficult for people to find products. We had a large catalogue, but the search, filters, and mobile navigation were frustrating customers. The team completely changed how the store handled product discovery and made the experience much easier to use on mobile. I was especially impressed by how much thought went into the customer journey rather than just the visual design. They understood what we were trying to achieve and turned it into a store that actually feels built for our customers. We’re genuinely proud of the result.
The mobile experience is probably my favourite part of the new site. We had spent a lot of time making sure the desktop version looked right, and the team kept pushing us to think about how everything would actually feel on a phone too. They were right. The navigation is clean, the interactions feel natural, and everything we’ve tested so far works exactly as it should. They also went through the links, forms, integrations, and other details more than once before launch, which I really appreciated. And even after going live, we could still reach out when something came up. The whole process felt friendly, organised, and surprisingly straightforward.

Work Culture
Bad markup can do more harm than none, because Google may ignore conflicting data. These are the habits we bring to Shopify schema markup and every other platform.
We mark up only ratings your shoppers can see on the page. Hidden or invented ratings break Google's rules and can cost you the stars.
When your theme and an app both print the same data, we switch one off. Google then gets one clear answer about each of your products.
Prices, stock, and ratings come from live store data, not hardcoded numbers. Your markup stays right through sales and restocks.
We test your products with variants, sale prices, and no reviews, not just your best seller. Those edge cases are where most markup errors hide.
Google stopped showing FAQ rich results in May 2026, so we won't sell FAQ markup as a search feature. We'll say which markup still matters.
The markup lives in your theme code, not in an app you rent. If you leave us, it keeps working and any developer can read it.
Overview
DeveloperLook implements review schema and product markup for ecommerce stores so Google can show ratings, prices, and stock in search results. We audit your theme and app output, write Product, Offer, AggregateRating, and BreadcrumbList JSON-LD, remove duplicates, and test every template. Projects start at $650 and take 1 to 4 weeks, and the code stays yours.

Good fit
Stores missing stars in Google
Your competitors show star ratings and prices under their listings, while yours show a plain blue link despite real reviews.
Shopify stores with app conflicts
Your theme and review app both print Product markup, and Search Console flags duplicate items on every product page.
WooCommerce and BigCommerce stores
You run WooCommerce or BigCommerce, and the default markup leaves out fields Google recommends, such as shipping and return details.
Marketing teams tracking rich results
You want structured data implementation that someone checks after launch, because theme updates keep breaking the markup.
Agencies without a schema specialist
Your agency handles content and ads, and you need someone to write and test product schema markup under your brand.
Not a fit
Sitewide technical fixes
You need crawl, canonical, and rendering fixes across the whole site. Our Technical SEO Services page covers that work.
No reviews yet
Your products have no reviews yet. Markup can't create stars from nothing, so start with a review app first.
Collection copy and filters
You want category copy and filter rules for collection pages. Our Collection & Category Page SEO service covers that.
Budget under $650
Your budget is under $650. Your theme's built-in markup and Google's free testing tools can cover a small catalog.

Implementing schema with us costs $650, $1,300, or $1,950, depending on scope. The $650 plan fixes Product and Offer markup on every product page. The $1,300 plan adds reviews, breadcrumbs, and store policies. The $1,950 plan adds variants, markets, and blog articles. Very large or custom catalogs get a fixed quote after the free check.
Schema projects take 1 to 4 weeks with us, depending on the plan. Product markup fixes take 1 to 2 weeks, and the full catalog setup takes 3 to 4. Google then recrawls your pages over days or weeks, so we request indexing for key products.
Review schema is structured data that tells Google a product has customer ratings, so its listing can show stars and a review count. It uses AggregateRating for the average and Review for single reviews, inside Product markup. Ratings must be visible on the page, and reviews about the business itself don't get stars.
Competitors show ratings and prices because their product pages carry valid markup that Google chose to display. Their Offer includes price, currency, and stock, and their ratings come from visible reviews. Missing fields, duplicate app markup, or ratings Google can't match to your page stop that. Google decides what appears, but valid markup makes your products eligible.
A Shopify schema markup implementation involves auditing your theme's output, then writing one clean set of JSON-LD in the theme code. Many Shopify themes print Product markup through the structured_data Liquid filter, so we extend it instead of duplicating it. We add ratings and GTINs from metafields and test on a duplicate theme.
You add structured data to Shopify by editing your theme code, installing a schema app, or combining both carefully. Theme code gives the most control, because it can read live prices, stock, and metafields. Apps are faster, but many add a second copy beside your theme's markup. Either way, check the result in Google's Rich Results Test.
Product, review, FAQ, and breadcrumb schema describe different parts of one page, so they sit side by side without conflict. Product and Offer carry the item, price, and stock, with review markup nested inside. BreadcrumbList shows the category path in desktop results. FAQ schema no longer earns a rich result, since Google dropped FAQ results in May 2026.
You test schema with Google's Rich Results Test for eligibility and the Schema Markup Validator for general schema.org errors. Test a product with variants, one on sale, and one without reviews. After your launch, Search Console's Merchant listings and Review snippets reports show errors across your catalog.
Adding schema can break your theme when code is edited on the live store without testing. JSON-LD sits in a script tag and doesn't change how your pages look, but a Liquid or PHP error can. We work on a duplicate theme or staging site first, and we remove duplicate app markup.
We keep your markup correct for 30 to 90 days after launch, depending on your plan. In that window, we fix errors from theme updates, new apps, or catalog changes. The Full Catalog Markup plan adds a checklist for new products. You own every line of code, so any developer can maintain it.
