AI agents for Google Merchant Center
A Monmo agent looks after Google Merchant Center like an ecommerce assistant who reads the diagnostics every morning. It finds products that were disapproved or limited and why, improves titles and descriptions, fills in missing GTINs and attributes, and checks that prices and stock match your shop. It works in your own Google account and asks before it changes product data, feeds or settings.

What agents do in Google Merchant Center
Check product issues every morning
At 8 each weekday it reads the product issues in Merchant Center, groups them by reason, such as missing image, price mismatch or policy, and lists the products that stopped showing since yesterday.
AskEvery weekday at 8, tell me which products were disapproved or limited since yesterday and why.
Fix price and availability mismatches
When the price or stock in your feed disagrees with the product page, it compares both with your Shopify admin, shows which one is wrong and prepares the correction for your approval.
AskFind products where Merchant Center says the price doesn't match our site, and tell me which side is wrong.
Write better product titles
It rewrites titles so the words shoppers search for come first, such as brand, product type, size and colour, within the character limit, and drafts descriptions that stick to the facts.
AskRewrite the titles of our 40 best-selling jackets as brand, type, key feature, colour and size.
Fill in missing attributes
For products missing a GTIN, brand, size or gender, it finds the value on the product page or the supplier sheet, flags the ones it could not confirm, and prepares a supplemental feed in Google Sheets.
AskList products missing a GTIN or brand and prepare a supplemental feed with the values you can confirm.
Explain a policy disapproval
When a product is disapproved for a policy reason, it reads Google's policy page, compares it with your listing and landing page, and tells you what to change before you request a review.
AskThree of our supplements were disapproved for a policy issue. Tell me what Google objects to and what we could change.
Report product performance
Every month it reports clicks and impressions by product and category, adds sales from Google Analytics, and lists products with many impressions and few clicks, which often need a better image or price check.
AskOn the 1st, report last month's top and bottom 20 products by clicks, and suggest what to fix.
Prepare promotions
For a sale it prepares the promotion details, dates and the products it applies to, checks that your site shows the same offer, and submits only after you approve.
AskPrepare a Merchant Center promotion for 15 percent off winter coats from 1 to 7 December. Check our site matches first.
How it connects
- 1You connect the Google account that is a user on your Merchant Center account once. The agent works with that user's access; changing settings or users needs an admin role.
- 2You choose which agents use Merchant Center. An ecommerce or marketing agent fits, often the same one that works in Shopify and Google Ads.
- 3Reading diagnostics, product data and performance needs no approval. Editing products, uploading or changing feeds, requesting reviews, creating promotions and changing shipping or return settings ask first.

Questions people ask
Can an AI agent fix disapproved products in Merchant Center?
It finds them, explains why and prepares the fix. A Monmo agent reads each product's issues, checks your site and feed, and drafts the correction or a supplemental feed. It saves changes after you approve, through the Merchant Center connection, or in its own browser when the connection does not cover something.
Can an AI agent optimise my Google Shopping feed?
Yes. The AI agent rewrites titles and descriptions around what shoppers search for, fills missing attributes, and groups products with custom labels you can use in Google Ads. It sticks to facts from your product pages and does not invent specifications or claims.
Does it work with a Shopify product feed?
Yes. Many shops send products to Merchant Center from Shopify. The agent compares the two, tells you whether to fix a product in Shopify or in Merchant Center, and keeps changes in the system that feeds the other, so a fix is not overwritten at the next sync.
Will the agent request a review from Google for me?
Yes, but only once you have approved it. It first checks that the issue is really fixed on the listing and landing page, because Google reviews the product again and a repeated failure helps nobody. The decision to request a review, and to appeal, stays with you.
