Google Merchant Center Updates: An Ecommerce Checklist for 2027
Prepare your store for Google’s January 2027 image rules, check product videos and shipping data, and interpret the 2026 reporting changes carefully.
Your next ecommerce improvement may be a catalogue clean-up. Google’s 2026 Merchant Center updates give retailers a concrete reason to review product images, delivery information and reporting before commissioning another campaign.
The most useful deadline to plan around is 31 January 2027, when Google says it will enforce a higher minimum image resolution. There are also changes already in effect. Here is what to check, who should own the work, and how to avoid confusing a reporting change with a sales problem.
Facts checked against Google’s official documentation on 21 October 2026. The work plan and examples below are ElloSpaces recommendations, not Google requirements.
1. Audit product images before the January deadline
Google’s product data update, dated 14 April 2026, sets a minimum resolution of 500 × 500 pixels for primary and additional product images across categories and marketing methods, with enforcement beginning on 31 January 2027. Warnings began in April. Google also says it may optimise some undersized images automatically; these can be identified in Merchant Center.
Start with the actual files your product feed submits. A large image in your design folder does not help if the feed points to an old thumbnail. Check primary images and additional views separately, including variants that have their own photographs.
Build a working list with four columns: product identifier, submitted image URL, pixel dimensions and person responsible. Group the fixes into replacement photography, export corrections and feed mapping errors. Those are different jobs and should not all land with the designer.
Meeting the pixel minimum is only one check. Inspect the result on a phone: can a buyer see the finish, shape and relevant details? Stretching a small photograph may increase its dimensions without giving customers a useful view of the product.
2. Treat product videos as a selective test
The same Google announcement introduced an optional video_link attribute. Submitted videos became eligible to serve from 30 June 2026, subject to validation. Google states that video policy or quality errors prevent the video from serving without stopping the associated offer from serving.
Eligibility does not guarantee display. Before paying to film the whole catalogue, check the current video specifications and your account’s diagnostics, then test a small set of products.
An illustrative example: a retailer selling folding desks could show the folding mechanism, the working surface and the space needed when stored. That answers a buying question. A decorative brand animation may look polished while leaving the same question unanswered.
Use a pilot with a clear owner, a production budget and a review date. Record what changed and when. If several page elements and ad settings change together, attributing any improvement to the video becomes difficult.
3. Make shipping promises agree across systems
Google’s April update also introduced product-level handling cutoff time and minimum order value attributes. Whether you should use them depends on how your store actually fulfils orders; adding fields is not a substitute for confirming the underlying rules.
Ask the operations team to describe a real order placed just after the daily cutoff. When will it be processed? Does the minimum spend apply to every location or only certain delivery options? Then compare that answer with the product page, checkout and feed configuration.
For example, a store might display “dispatch today” on a product page while its warehouse has already closed. Fix the promise and the information handoff before changing the advertisement. Customers experience one purchase, even when separate teams manage its parts.
4. Check reporting definitions before moving your ad budget
Google announced Merchant Center reporting changes on 11 August 2026, starting from 24 August. These separate eligible YouTube affiliate results from organic traffic, revise YouTube organic measurement and broaden ads product reporting. The first two changes also affect historical data from 1 July 2026. Reported totals can therefore shift because of measurement changes.
Our recommendation: annotate this change in your monthly review and compare like-for-like traffic categories. Cross-check paid orders, refunds and net revenue in your commerce system before concluding that demand has fallen or an ad campaign has improved.
A lower organic total is a signal to investigate. By itself, it does not tell you whether fewer customers bought. Equally, more reported impressions are not proof of better commercial performance.
5. Check the product page Google can actually read
Google’s merchant listing documentation says Product structured data can make pages eligible for richer product displays. It recommends testing with the Rich Results Test and URL Inspection. Display is not guaranteed.
Review a small but varied sample: a discounted item, an unavailable variant, a product with delivery restrictions and a normal full-price item. Compare the visible page with the feed and structured data. Ask whether the price, currency, availability and destination URL describe the same offer.
For ecommerce website design, this should be part of acceptance testing. A page can look finished while its product data remains wrong.
A manageable plan for a small team
Week one: export image URLs, inspect Merchant Center issues and prioritise products with active campaigns or meaningful sales. Keep an untouched copy of the export so fixes can be traced.
Week two: replace weak assets, correct feed mappings and test the product-page sample. Assign shipping questions to the person who controls fulfilment rather than asking the marketing team to guess.
Week three: run a limited video pilot if it answers a real customer question, and update reporting notes. Review resolved issues and commercial outcomes separately. Neither an approved feed nor a better photograph guarantees more sales.
If you are choosing an ecommerce website development agency, ask who will maintain this work after launch. Agree who owns catalogue accuracy, feed failures, page changes and monthly checks. This is routine WebOps work, and it needs a named owner.
