TikTok Shop is not just another place to send your product feed.

That was one of the clearest takeaways from our team’s visit to TikTok HQ in London. For retailers and agencies used to Google Shopping, it can be tempting to approach TikTok Shop in the same way: get the products live, make sure the data is in place, then see what performs.

But TikTok Shop works differently.

Google Shopping is mostly search-led. A customer searches for something, Google uses the product feed to understand what each item is, and the strongest matches get shown. That is why broad catalogue coverage can be so valuable. The more products Google understands properly, the more chances you have to appear for relevant searches.

TikTok Shop is more discovery-led. People are not always looking for a specific product when they open the app. They might see something in a video, watch a creator demonstrate it, join a live shopping session, or buy because the product feels relevant in that exact moment.

That changes the starting point.

It also plays into the work we already do at Shoptimised: helping retailers and agencies use product data, rules and performance signals to make better decisions about what needs attention first. For TikTok Shop, that means using those signals to review which products are worth pushing before time, content and resource are committed.

Instead of asking, “How do we push the whole catalogue?”, the better question is:

"Which products are most likely to work in this environment?"

TikTok Shop Still Needs a Considered Product List

One of the strongest takeaways from the event was that TikTok Shop needs a more considered product selection process than Google Shopping.

A retailer might have thousands of products, but that does not mean every product deserves attention on TikTok Shop from day one.

The platform still suits a more curated approach. Even when Smart+ gives retailers more room to use catalogue data, products with clear appeal, strong stock availability, healthy margins and good content potential give the platform a better starting point.

That matters because TikTok Shop is not just about getting products listed. It needs content, creators, testing, pricing, compliance and consistency.

When the product list is too broad, creator briefs become vague, content planning gets messy, and reporting becomes harder to read.

That focus makes the whole launch easier to manage.

Where Smart+ Changes the Conversation

Smart+ makes this slightly more nuanced.

Previously, TikTok Shop activity was often approached with a much smaller selected product list. Smart+ changes that conversation because it gives retailers more room to use catalogue data and allows TikTok’s AI to help push what is working best.

But more product data does not mean the full catalogue should go in without thought.

TikTok still needs enough conversion data to learn. Its guidance says achieving 50 conversions is the most significant indicator of passing the learning phase. For Smart+ Web campaigns using target CPA or minimum ROAS, TikTok recommends a daily campaign budget of around 30 times historical CPA, and no less than 10 times.

For example, if your average cost per sale was £25, a daily budget based on 30 times CPA would be £750.

That does not mean every retailer needs that exact budget. It does show why product selection matters.

If the products you give TikTok are too broad, too weak or not suited to the channel, the learning process can become expensive quickly.

The goal is not to restrict everything to a tiny product list.

It is to give TikTok stronger inputs: products with clearer signals, enough stock, workable margins and a realistic chance of performing in a discovery-led environment.

That is where trending rules can help.

When Trending Rules Become Useful

Trending rules help identify products that are starting to gain momentum over a short period of time. For example, a product might be labelled as trending if conversions or ROAS increase sharply in the last 7 days compared with a longer period, such as the previous 30 days.

The exact rule can change depending on the client, category and volume of data. A large retailer may need tighter criteria to avoid pulling in too many products, while a smaller retailer may need a broader rule to make sure the shortlist is still useful.

But the purpose is simple:

Spot the products that are already starting to move.

Retailers usually have plenty of product opinions inside the business. Merchandising teams have priorities. Founders have favourites. Agencies have performance views. Commercial teams know what needs shifting.

All of that context matters, but it can also make product selection feel subjective.

Trending rules add a clearer signal.

If a product is already seeing a lift in conversions or ROAS on another channel, it may be worth considering for TikTok Shop. Not because it guarantees success, but because it shows there is already some momentum behind it.

It gives teams something more useful than opinion to work with.

Why This Matters When Launching on TikTok Shop

Starting on a new channel can get complicated quickly.

There are listings to manage, content to create, creators to brief, offers to plan, stock levels to watch and commercial expectations to set.

If the starting point is “let’s upload everything and see what happens”, the launch can become harder to manage and harder to learn from.

A trending-led approach gives teams a clearer starting point.

Instead of starting with the full catalogue as the default, retailers can begin with products that already show signs of customer interest. From there, they can sense-check each product for TikTok Shop:

Is it easy to explain in a short video?

Does it have enough stock behind it?

Is the margin workable?

Could a creator demonstrate it clearly?

Does it fit the kind of content people actually engage with?

That does not remove the need for testing, but it gives the test a better structure.

For example, if a fashion retailer sees a product type picking up quickly through Google Shopping, that could be reviewed for TikTok Shop potential. If a gifting brand sees certain SKUs rising before a seasonal moment, those products could be prioritised for content before the peak passes.

The key is speed.

TikTok trends can move quickly, so retailers need a way to spot product momentum early and decide what to do with it.

Product Data as a Decision-Making Tool

Product data is often treated as a technical job.

Get the products listed. Fix the missing fields. Make sure the feed is accepted.

But when product data is combined with performance signals, it becomes much more useful. It can help teams decide which products are worth pushing, which products need more work and which products are not ready for attention yet.

For TikTok Shop, that matters because attention is limited. You cannot give every product the same level of content, creator support and commercial focus.

Trending rules help make that choice more deliberate.

They give retailers and agencies a way to move the conversation from:

“We think this product might work.”

To:

“This product is already gaining traction, so it is worth a closer look.”

That is where Shoptimised can help: turning product-level data into clearer rules and signals, so teams can see which products are worth reviewing first.

The Takeaway

TikTok Shop should not be treated like a copy-and-paste version of Google Shopping.

The buying behaviour is different. The role of content is different. The way products gain attention is different. And with Smart+, there is more automation in the mix.

But automation still needs strong inputs.

Rather than starting with the full catalogue by default, retailers should look for the products that already have momentum, then decide whether those products are suitable for TikTok Shop based on stock, margin, content potential and customer appeal.

Trending rules give teams a practical way to do that.

They help turn product-level performance into a clearer starting point, so retailers can focus their time, content and testing around products with stronger signals behind them.

Not every product needs to be pushed everywhere.

But spotting the right products earlier could give brands a much better place to start on TikTok Shop.

The challenge with this account was clear: too much revenue was coming from too few products.

Before working with Shoptimised, One Stop for Safety was heavily reliant on a very small number of products to drive performance through Google Shopping. Just 1% of products generated 100% of revenue, while 84% had no clicks at all. We also found that 55% of budget was being spent on products that did not convert.

That left the account over-reliant on a tiny portion of the catalogue, with too much spend going towards products that were not delivering a return.

After joining us in July 2024, One Stop for Safety launched on Incremental Sales, designed to drive revenue from products that were not getting clicks or not converting, without cannibalising what was already working.

The results were significant:

The most important shift was not just higher revenue. It was that far more products started contributing to sales.

That matters because when an account depends too heavily on a tiny number of products, growth becomes harder to sustain. Getting more of the catalogue contributing gives retailers a stronger base to grow from and reduces the pressure on the same products to keep carrying performance.

As Adam, Performance Manager at Shoptimised, puts it:

“What stood out here was how quickly more of the catalogue started pulling its weight. Once the account was not relying so heavily on the same small group of products, growth became much easier to scale.”

For retailers running Google Shopping, this is often where the next stage of growth sits. If too much revenue is coming from too few products, there is usually more value sitting in the wider catalogue than the headline numbers suggest.

If AI is going to read, explain, compare, and even help buy products, then product data needs to be clean, accurate, and easy for Google to understand.

That was one of the clearest takeaways from Google Marketing Live 2026. There were plenty of announcements, but for retailers, the bigger story is not just more AI. It is what those new experiences rely on. Google is introducing more UCP-powered features, rolling out native checkout for eligible UCP merchants, expanding AI support inside Merchant Center, and putting more emphasis on product descriptions and conversational attributes for discovery.

Bigger Than a Shopping Update

Google is building towards a more agentic shopping experience.

Its own announcement talks about a future anchored by Universal Cart, Agent Payments Protocol and the Universal Commerce Protocol, with new UCP-powered features now coming to Google. Universal Cart is designed to work across retailers and across services like Search and Gemini, while native checkout is being added for eligible UCP merchants. At the same time, Google is introducing new tools inside Merchant Center to help merchants understand how they are performing on AI surfaces.

For retailers, that matters because these systems are only as useful as the product information they are working with. The better Google can understand a product, the better chance it has of surfacing it in the right moment and in the right format.

Google’s AI Needs Better Product Data

Google says strong product descriptions are critical for brands to get discovered in the AI era. It is also introducing conversational attributes so retailers can update product descriptions to better reflect how people search today. Ask Advisor is being built into Merchant Center as a new collaborator, with the ability to share tailored insights, complete tasks, and connect across Google Ads and Google Analytics.

This is not just about getting products into Shopping anymore.

It is about making sure Google can understand what a product is, who it is for, and when it should appear, whether that is in Shopping results, AI-assisted search journeys, or newer commerce experiences built around UCP and native checkout. Google is also launching AI-powered Shopping ads, where Gemini can pull up relevant products and instantly write a custom explainer about why a product may be the right choice, plus Business Agent for Leads, which uses website content to answer questions inside an ad.

What AI Readiness Actually Means

For retailers, this does not need to be overcomplicated.

It means accurate titles, complete attributes, strong descriptions, clean categorisation, up-to-date pricing and availability, and feed structures that make products easy for Google to interpret across more AI-led discovery experiences. That has always mattered, but it matters more when AI is being asked to recommend, compare, explain, and support purchases using merchant data.

Why This Matters for Retailers

As Google moves towards more AI-led discovery and commerce, product data becomes even more important. If Google’s systems are going to read, interpret, compare, and act on that data more often, retailers need feeds that are clean, accurate, and easy to understand.

That is exactly where Shoptimised comes in.

If retailers want to get UCP ready for AI, feed optimisation needs to move up the priority list, and Shoptimised is built to help with that. We help retailers improve titles, descriptions, attributes, categorisation, and feed structure so Google can understand products properly, show them more effectively, and use that data across the next generation of AI-led shopping experiences.

Start With the Feed

Review titles and descriptions. Check missing attributes. Look at categorisation. Make sure pricing and availability are accurate. Think about whether your product data is genuinely readable and useful, not just technically valid.

Because if this year’s Google Marketing Live showed anything, it is that AI shopping is moving quickly, and the retailers who are best prepared will be the ones whose product data is ready for it. 

If that feels like a big job, it is exactly the kind of challenge Shoptimised is built to help with.

We had 24 hours in Dublin, with a full day at Google’s Dublin office packed into the middle of it.

The goal was simple: spend time with the Google team, have the conversations you don’t get to have over email, and make sure we’re aligned on our 2026 goals together.

It was a full day packed into a tiny window, and it reminded us why relationships matter just as much as strategy.

This was the day, start to finish.

9.30am: Newcastle to Dublin

Early start, airport coffee, then a short flight over. We landed and headed straight for a taxi.

12.00pm: Hello, Google Dublin

By midday, we were at Google’s Dublin office meeting the team.

We like to think Shoptimised HQ is pretty well set up, but Google is on another level. The place is built for people who spend their whole day there, and it shows, with space to focus, space to switch off, and plenty of fun built in.

Then it was time for lunch and a chance to settle in before the afternoon kicked off.

12.30pm: Lunch in the Google canteen (and a familiar face)

Lunch in the canteen was next, and it immediately put every sad desk lunch we’ve ever called ‘fine’ into perspective.

Ulises popped over to join us, too. He was our Senior Partner Manager in the early Shoptimised days, so it was genuinely great to see him again and have a proper catch up before the afternoon meetings.

1.30pm: Ping pong defeat, then a full tour

We made the mistake of thinking we stood a chance at ping pong. Shubham fixed that quickly.

Two takeaways:

After that, Shubham took us around the office and showed us all the fun stuff, which made our “we’ve got a games room” confidence wobble again. We’re still waiting for them to accept our foosball rematch at Shoptimised HQ.

2.30pm to 5.00pm: Meetings, aligning for 2026

This was the core of the day.

We spent the afternoon with the Google team talking through where we’re heading in 2026 and what ‘good’ needs to look like for agencies and retailers.

The best meetings are the ones where you get into specifics. Not ‘growth’. Not ‘innovation’. Just practical alignment on things like:

It was a good reminder that most challenges are the same everywhere. The answers are usually not clever campaign tricks. They’re fundamentals you can repeat: cleaner data, cleaner structure, and decisions you can stick to.

5.30pm: The post-meeting pint

Meetings done, heads full, time for the traditional reset.

That first pint of Guinness in Dublin always feels earned, even when you’ve only been there a few hours.

7.30pm: Steak dinner

Steak dinner was exactly what we needed after a day of caffeine and conversation.

It’s where the debrief happens without anyone opening a laptop. Just good food, and a proper chance to talk through what we’d covered before the night started.

8.30pm until late: Out for drinks

After dinner, we went out for drinks and let the day wind down.

Next thing we knew, it was late, and the early flight home was starting to feel very real.

The real takeaway

We were in Dublin for 24 hours, with a full day at Google’s Dublin office packed into the middle of it. It sounds quick, because it was, but it did exactly what we needed it to do.

It gave us time in the room with the Google team to align on our 2026 goals together, talk through what’s working, what needs tightening, and what we want to push next.

There’s something useful about stepping away from the day-to-day and having those conversations face-to-face. You leave with clearer priorities, fewer assumptions, and a much shorter list of “we’ll come back to that”.

It was a good reminder that the best progress still comes from getting in a room and talking things through. Which explains why at Shoptimised, someone is always pulling you into a meeting room.

What it means for retailers and the actions Google Shopping Ads users should take now

AI shopping is moving from ‘help me research’ to ‘help me buy’. Instead of a customer clicking through search results, an AI assistant can understand intent, compare options, confirm delivery dates, and complete checkout inside the conversation. 

This is not just a new ad format. It is a change in how your products get discovered. When the buyer becomes an agent, your product data becomes the storefront. If your product feed is not optimised, you will be ruled out before you compete.

 

Recent announcements:

Google is bringing ‘Buy’ buttons and checkout into Gemini and AI Search, alongside a new standard called the Universal Commerce Protocol (UCP). Google is also introducing new Merchant Center data attributes for conversational discovery, and testing ads in AI Mode with a Direct Offers pilot.

Shopify is backing UCP as an open standard it co-developed with Google, and is encouraging merchants to plug into these AI shopping channels through Agentic Storefronts, managed centrally in Shopify Admin.

PayPal is framing this as a ‘protocol moment’, with consent, trusted identity, reliable payments, and fraud protection as non-negotiables when an AI agent is the one clicking ‘Buy’. For merchants, that means a focus on data structure, integration readiness, monitoring, and ongoing compliance as standards evolve. PayPal has now confirmed it supports UCP and says it will soon be a payment option within Google’s UCP-powered checkout.

Multiple players are competing to define the common language for AI shopping, and that is what is fuelling the ‘protocol wars’. Salesforce has also announced support for UCP, signalling adoption is spreading beyond Google and Shopify into wider commerce platforms.

What to watch: Some commentators suggest AI chat platforms may adopt marketplace-style economics, including charging fees when transactions happen inside the chat. The exact models are still emerging, but the direction is clear: more shopping activity will happen inside AI-led experiences.

 

What ‘AI shopping’ actually is

1) Shopping intent becomes conversational

Shoppers describe what they want: 'waterproof, recycled materials, under £100, delivered by Friday.' The AI turns that into requirements and finds products that match. This shifts the focus from SEO keywords to structured attributes.

2) Protocols connect the AI to retail systems

UCP is designed to standardise how AI agents communicate with retailers and service providers, so they can do more than recommend products. The goal is reliable discovery, checkout, and post-purchase support without custom integrations for every new AI channel.

3) Checkout happens inside the chat

The buyer might not visit your site at all. The AI can guide the purchase through a supported checkout, using approved payment methods and merchant rules. That reduces friction and makes clean data and reliable fulfilment even more important.

What this means for Google Shopping Ads users

Discovery is compressing

The classic customer journey is getting shorter. In many cases, a shopper may see only one recommended option. That raises the stakes on being included, trusted, and chosen based on the data the AI evaluates.

Your feed is moving from 'supporting asset' to 'decision engine'

When an AI chooses based on verified facts, your Merchant Center data quality directly shapes whether you are selected, not just whether you get a click.

Trust and accuracy become competitive advantages

If your price, stock, delivery promise, or product specs are wrong, the AI cannot confidently recommend you. This is not only a conversion issue, it can become a reputation issue inside agent-led ecosystems.

Measurement and attribution will change

If purchases happen inside an AI experience, performance signals will not always look like traditional click-through conversions. Be prepared for attribution to evolve, and start tracking performance at product and feed level, not only at campaign level.

 

How to prepare your Google Shopping Ads

In the context of the 'Protocol Wars' and the shift to agent-led shopping, feed optimisation platforms help translate retailer data into a format AI systems can reliably use. 

As Google builds the 'answer' through structured protocols like UCP, retailers need feed processes to enrich attributes, validate compliance, and refresh price and stock. Feed optimisation platforms such as Shoptimised are designed to automate those updates across channels, keeping products eligible, accurate, and competitive as AI-led checkout expands.

1) Upgrade your feed from 'good enough' to 'agent-ready'

Focus on the attributes an AI needs to confidently choose a product:

Why it matters: AI shopping interprets intent through attributes and constraints more than SEO keywords.

2) Treat inventory and pricing freshness as a core KPI

Increase refresh cadence where possible and set monitoring for:

Why it matters: AI agents need real-time price and stock to buy. Stale data breaks trust and can knock you out of recommendations within the AI ecosystem.

3) Prepare for more 'discovery surfaces' inside Google

Assume your products will be evaluated in more places than the classic Shopping results page, including conversational journeys where shoppers ask follow-up questions. Make sure your feed can answer those questions with structured facts.

4) Build a testing loop for titles and key fields

Run controlled experiments on:

Why it matters: when shoppers see fewer options, small improvements in relevance matter. Shoptimised helps you test title and attribute changes across your feed, and scale the winners based on performance.

5) Review your data-sharing and compliance posture

As AI shopping blends ads, recommendations, and checkout, scrutiny will increase. Make sure you can clearly explain:

Why it matters: protocols like UCP are already specifying stronger consent and verification mechanics, so merchants should expect governance and compliance requirements to become more formal over time.

6) Track the protocol landscape without betting everything on one winner

Google and partners are pushing UCP, while others will push alternatives. You do not need to predict the winner today. You do need to keep your catalogue structured and portable so you can adapt quickly.

 

The simple takeaway

AI shopping is turning discovery and checkout into an agent-led conversation. Google is setting the standards for that shift with UCP and in-chat checkout across Search and Gemini.

For Google Shopping Ads users, the winning move is simple: optimise your feed. The brands with the cleanest, most accurate, most current product data will be the ones AI systems trust and recommend. That is where feed optimisation platforms, like Shoptimised, help by keeping your catalogue structured, compliant, and up to date at scale.

May update (2026)

AI shopping is moving quickly from 'nice to have' to a real traffic source retailers need to take seriously. New Adobe figures reported in May show UK shoppers arriving from AI sources converted more often than those coming from traditional search, with the UK AI shopping conversion rate up 182% year on year and 543% since January last year.

At the same time, the platforms are building more of the shopping journey directly into the AI experience. Google has been pushing Shopping features in AI Mode, including richer product discovery, virtual try-on using your own photos, and more automated purchase flows.

Amazon is also taking its 'Alexa for Shopping' capability beyond Amazon. It is licensing the underlying tech to other retailers through AWS, with Kate Spade cited as an early customer.

The common thread is simple: as shopping becomes more AI led, clean product data matters even more. If your titles, attributes, pricing and availability are messy, the AI layer has less to work with, and you lose visibility where customers are starting to browse and decide.

Is Your Product Data Ready for AI Shopping?
