#BlinkTank: Shopify launches Canvas to let AI redesign your store
This week's big story is Shopify Canvas, a new AI-driven site builder that has reignited the debate over the future of dev agencies. While the potential for it is huge, My immediate concern is that it introduces a new way and incredibly creative way to break things.
Also this week, OpenAI has overhauled ChatGPT ads and named a long list of attribution partners, which will please some people more than it pleases me.
After that - Google will start pulling promotions from your website into some ads from 12th October, a separate promotion mode setting is appearing in more Google Ads accounts ahead of Black Friday, Google has refreshed its guidance on helpful and AI-generated content, discounts have arrived in Shopify Rollouts, Shop now syncs carts across devices, and Shopify Analytics has gained annotations. We’re also hiring a new eCommerce PPC manager at Blink.
On to the news!
Shopify Canvas, and the case for governance
Canvas is one of those announcements that came out of the blue and was no surprise at all, given that the company has gone all-in on AI. Shopify is pitching it as a way for people who aren't designers or developers to build a heavily customised store, either by editing visually on a workspace that shows every page at once or by asking Sidekick to change things in chat. As always, the demo looks really strong, and it has set off the usual round of commentary about the death of the Shopify development agency.
We've been through this pattern before and have a fair idea how it plays out. Canvas will do a decent job for stores with limited requirements and will help a lot of new stores get off the ground, but for anyone with more complex needs it isn't going to replace an experienced partner. The changelog is even quite explicit about the gaps, with no Theme Store themes, Markets, translations, app blocks or app embeds yet.
The part I'd put most weight on is governance, and it comes back to something I say time and time again - very few people realise how fragile all of this is. Shopify isn't really just a platform any more, it is the point of truth for selling your products online, and an enormous amount spirals out of it, from Merchant Center feeds to what an AI agent sees when it shops.
Canvas puts a chat box in front of that pipeline, so the question isn't whether it can build the store, it's who is allowed to change it and who checks what impact a change has. We'll be testing Canvas thoroughly over the next few weeks, and we'll report back on what we find.

ChatGPT upgrades ads for US audiences
On 5 October OpenAI announced a new ad format that shows a product image and a "Learn more" button alongside images generated in ChatGPT. It will appear in the US only from later this month, for a limited group of advertisers. OpenAI says the ads are labelled and don't influence ChatGPT's answers.
Another interesting part of this announcement is measurement. OpenAI named Triple Whale, Northbeam, Rockerbox, Fospha and others as attribution partners. Tracking and attribution is obviously a hot topic for AI ads, so I'm sure this will be welcomed by a lot of people. On the other hand, I'm not a massive fan of these platforms for a number of reasons, the main one being the lack of transparency in how they build their models and reporting. I doubt this is going to put off everyone though.

Google will pull promotions from your website from 12 October
Google has told some advertisers that from 12 October it will automatically identify promotions on their website and add them to eligible campaigns as promotion assets. It applies to Search and Performance Max campaigns that have location assets attached and no manual promotions set up. Google hasn't said which countries or languages are included, so it's safest to assume your accounts could be afected.
Each automated promotion runs for less than 24 hours and only renews if Google can still verify the offer on the page, which makes your site the source of truth for what your ads say about discounts.
It's not hard to see how this ties in with our lead story on Shopify Canvas - an expired banner, a sale price left in a template or a conflicting offer on a collection page could end in your ad campaigns, so this is another example of the importance hygiene and governance.

Google's promotion mode is appearing in more accounts ahead of Black Friday
Promotion mode isn't new, but it has started showing up in more Google Ads accounts over the last couple of weeks. Since it was announced on 15 June for Search and Performance Max it's been pretty absent across our accounts, but over the last week or so, we've spotted it appear for a handful of clients.
Promotion mode is separate from the automated promotions change above, which is about the text in your ads rather than bidding. According to Google, it lets you schedule a promotion window of between three and 14 days, and during that window you can loosen your target ROAS and add extra daily budget, with everything reverting automatically when it ends.
It's worth noting that it can raise spend as well as loosen the efficiency target, so it is an instruction to spend more rather than a target setting. It's different from seasonality adjustments, which tell Google to expect a change in conversion rate rather than change how much you're willing to pay.
It helps to see this next to the change Google made on 17 August, when budget-limited campaigns on target CPA or target ROAS started delivering closer to their stated targets, so campaigns that never reviewed their targets may now be bidding harder than before. Whether promotion mode beats a manual bid and budget uplift for a Black Friday sale is something we haven't tested. The practical step here is to ask whoever runs your account whether the setting is visible and what window, budget and ROAS floor they'd use.

Google updates its guidance on helpful and AI-generated content
Google updated its helpful content guidance on 5 October, and refreshed its companion page on generative AI content a few days earlier. Two changes stand out for ecommerce - Google now asks whether a site's use of AI is self-evident to visitors, and its definition of main content explicitly includes tabbed sections, which is where many product pages keep descriptions, specifications and delivery information.
The generative AI page also says AI-written output should be checked for accuracy, including metadata, structured data and alt text, which is a sensible rule for any catalogue generating descriptions or attributes at scale. Neither page introduces new penalties, so this is clarification rather than a change in enforcement.

Discounts can now be scheduled and tested in Shopify Rollouts
On 2 October Shopify added discounts to Rollouts, which means a discount can now go live alongside theme and checkout changes as a single campaign launch. You can also show an offer to a share of online store traffic first, or test it against an existing promotion to compare conversion.
For large catalogues this could take some of the manual coordination out of sale periods, where the discount, the homepage changes and the checkout messaging all need to go live together. Black Friday is not far off, so it may be worth trying on a smaller promotion first, and since Shopify hasn't said which plans get it beyond noting it's in the new admin, check it's available on your store before spending too much time on it.

Shop now syncs carts across devices
Shopify announced on 5 October that the Shop app can verify a shopper's identity while they browse your store, which enables faster sign-in, carts that stay synchronised between the Shop app and the storefront, and built-in cart recovery reminders. It is now supported on all browsers, and the Shop Pay button will show previously used payment methods.
For stores where people tend to browse on a phone and buy later on a laptop, the potential is clear, though Shopify hasn't published any conversion data yet, so this is still very much something to watch. If you see a shift in cross-device or returning-visitor behaviour in Analytics, this may be one of the reasons.

Annotations arrive in Shopify Analytics
This is a simple update that has the potential to be incredibly useful - Shopify has added annotations to supported time-series reports in Analytics.
You can attach a title, description, date range and type to events such as campaign launches or promotion, and yhey're shared with staff who have Reports permissions.
It follows on neatly from last week's point about the September spam update, which is due to finish rolling out this week. If your traffic or conversion moves around now, an annotation noting the dates, along with any site or promotion changes, will likely save someone a lot of guesswork further down the line.

Jobs
Closer to home, we're hiring an eCommerce PPC Manager here at Blink. It's a senior, hands-on role owning a portfolio of paid accounts end to end. Unsurpisingly, the person we're after has real Merchant Center and feed depth. Four-day week, hybrid or remote with a Norwich office, and we'd like someone in post for December or early January.
If you are hiring and the role fits someone with large-catalogue Shopify experience, or you are looking and have that background, send me a message.
Partner shout-out: Atomz AI
I'm deeply cynical about SaaS platforms that promise to help with AI discovery, but I've been hugely impressed with Atomz AI. I’ve had a few conversations with Ankit Minocha and the team recently, and there's a lot of overlap with how we think about product data.
Their Shopify Catalog Visibility Report is genuinely useful, and they have a free catalogue audit that shows where your brand ranks against competitors. The Agentic Operator, a newsletter for Shopify operators on agentic commerce that goes out four times a week, is also well worth a read.

As ever, thanks for reading. If you found this useful, forwarding it on to someone else who runs or works on a large-catalogue Shopify store helps us more than just about anything.
See you next week.
