What MerchLight does
MerchLight is a Shopify app that checks your store every day for the problems that quietly cost you sales, gives your store a health score from 0 to 100, and tells you exactly what to change, starting with what matters most. It only reads your data: you make every change yourself.
Stock & orders
Sold-out best-sellers, best-sellers missing sizes, live products nobody can buy, orders waiting to ship and shipments without tracking.
Product pages
Thin descriptions, supplier text left behind, weak photos, sale prices that look like mistakes and products missing from your online store.
Speed & trust
How fast your store loads on a phone, the apps slowing it down or that you may be paying for without using, and the returns, shipping and contact pages shoppers and Google look for.
Google & ads
Products Google disapproved or limited, and your Google Ads and Meta Ads campaigns, spend and ROAS next to your store.
Where sales quietly leak — and how MerchLight helps
Most problems don't break your store. They just make it sell less. MerchLight checks your store, Google and your ads automatically, on a schedule, and turns what it finds into a clear plan.
Your Shopify store
Products, inventory and orders — every one of them.
- Best-sellers that ran out of stock, with the sales at stake
- Best-sellers with sizes or colours sold out, so shoppers can't buy the one they want
- Live products with no inventory
- Active products missing from your online store, so links and ads lead nowhere
- Sale prices that look like mistakes, like a compare-at price of 0
- Product descriptions that are empty, too short, or still full of supplier text like "Due to the light and screen difference…"
- Products with only one photo, or a main photo too small to look sharp
- Products that don't say their size or measurements, like a lamp or a vase with no height or width
- Abandoned checkouts: what shoppers left behind, how many came back, and whether a reminder email goes out (from Shopify or your email app, like Omnisend or Klaviyo)
- Variants without a SKU and products without images
- Paid orders waiting too long to ship, and shipped orders without tracking
- Your best-seller and your total sales for the month
- Your whole catalog, with no size limit, and the last 60 days of orders (the window Shopify gives apps)
Speed and trust
What shoppers feel before they buy.
- How fast your home page, a collection and a product page load on a phone, tested by Google PageSpeed Insights
- What slows each page down, in plain words — big images, too many apps, fonts — with the fix in Shopify
- Real-shopper speed from Google, when your store has enough visits
- The apps and scripts slowing your store down, and by how much
- Apps switched off in your theme, two apps doing the same job, and code left behind by apps you removed: apps you may be paying for without using
- Missing returns, shipping or privacy policies, or contact details, that put off shoppers and can get a store flagged by Google
- An About us page, an FAQ and terms that answer shoppers' questions
- A size guide on your product pages, for clothing and shoe stores
- Read from your public store pages and your published theme, never changed
Google Merchant Center
Why your products don't show on Google.
- Disapproved products and the reason Google gives
- Account settings that block products, like shipping or country setup
- Missing details that limit visibility, like age group, gender and color
- The full list of affected products, ready to export
- A separate Google score, so you know how healthy your listings are
Google Ads and Meta Ads
Your campaigns, checked against your store.
- Active, paused and removed campaigns, with a link to open each one
- Spend, conversions or purchases, cost per conversion and sales value
- ROAS for every campaign and for the whole account
- Daily budgets and how much of them each campaign uses
- Today, the last 7, 15 or 30 days, any single day or any date range
- You choose the period that counts for your ads score: 7, 15 or 30 days
- An ads score from your ROAS, which counts in your health score only when you spend on ads
Conversion boosters
What helps shoppers decide and buy.
- Product reviews with stars
- Express checkout buttons: Shop Pay, Apple Pay, Google Pay
- Recommended products on the product page
- Add to cart always visible on phones
- Email sign-up, and a free shipping message if you offer it
- Suggestions, weighted by how much each one usually helps sales, with Shopify's free options first

A healthy store over time earns a better cup. Trophies are never taken away.
How MerchLight uses Google and Meta data
Only if you choose to connect Google Merchant Center, Google Ads or Meta Ads.
- From Merchant Center, MerchLight reads the status of your products and account: which products are disapproved or limited, where, and why.
- From Google Ads and Meta Ads, it reads your campaign names, status, budgets, spend, clicks, conversions and sales value. It never reads your ad texts, audiences or anything about the people who saw your ads.
- It uses this only to show you your problems and your ad results inside the app.
- It is read-only: it never creates, changes, pauses or deletes anything in your Google or Meta accounts.
Your data stays yours
We follow the Google API Services User Data Policy, including the Limited Use requirements, and the Meta Platform Terms.
- Google and Meta data is never sold, never used for advertising, never used to train AI and never shared with third parties.
- You can disconnect Google or Meta at any time from the app, and we delete that data straight away.
- Read the full details in our privacy policy.
Built to read, never to change
- Read-only access to your store. MerchLight never edits products, orders or settings.
- No customer names, emails, phone numbers or addresses.
- Google and Meta connections are encrypted and can be disconnected at any time.
- Uninstall and your data is deleted within 48 hours. Read our privacy policy.
