February 18, 2020
Smart Shopping campaigns are upgrading to Performance Max campaigns by the end of Q3 in 2022.
Read our article on Performance Max for an in-depth look at the new campaign type.
There is rarely only one side to a story.
Smart Shopping is one of the few automations from Google that has really received overall praise. Remember when Smart Bidding first came out? It was absolutely hated.
What about AdWords Express (aka Smart Campaigns)? I wrote a highly critical article on AdWords Express back in 2013 and then met its creator at our agency office a few years later, where he mentioned the article. Talk about awkward.
Smart Shopping definitely splits the waters, but it has never had that universally hated phase that many new automations from Google experience.
That’s because it actually works.
Don’t get me wrong. I don’t like it. I feel the cons outweigh the pros, but I have a lot of good things to say about Smart Shopping. It is something that we will test in certain eCommerce scenarios (you’ll see why in the section on whether you should pay an agency to run Smart Shopping).
This article will not be a usual love it or hate it type of article. It’s not going to be about an agency who’s angry about losing hourly billings (we don’t charge hourly), and it’s not going to be a complete love story.
To find out whether Smart Shopping will fit your eCommerce store, let’s get started with the pros.
If you are running a manual Google Shopping campaign with one campaign, one ad group, and are running manual bids, then Smart Shopping will beat your performance 99 times out of 100.
That’s not necessarily because Smart Shopping is awesome, but because you are doing it wrong. You’re setting the bar too low, and Smart Shopping can easily beat your campaign’s performance.
Note: That’s an ode all “PPC Experts,” claiming Smart Shopping is the best thing in the world. Imagine how bad their campaigns were before?
Once you enable Smart Shopping, it will start using audience data, automated bidding on the Search Term level, and thereby optimize your campaign. This will lead to better performance than what you had before.
Smart Shopping is very limited in actions you can take. That also means it’s simple. For instance, you don’t have to add remarketing audiences to Smart Shopping. It takes care of that itself.
It can also use insights across its network (e.g., in-market audiences, demographics data, etc.) to improve your performance. Some of these areas are not available to us mere mortals.
This is also dangerous, though. What if I don’t want certain audiences? What if I have proactive insights to my market? What if I want to exclude converted users? You can’t control that.
Smart Shopping is not running on your typical Smart Bidding algorithm. Rather, it uses the Smart Bidding “maximize conversion value” goal.
In other words, it will try to get as much revenue out of the budget you make available to the campaign.
That can work exceptionally well. We’ve seen accounts running for a year on a set budget and actually hit the target ROAS each month without having a ROAS target. The campaign just had a set budget of $10,000. Pretty interesting.
I have a theory that Smart Shopping uses price comparison as a bidding factor. Something that we can’t use yet. The data (benchmark pricing) is available as a column in regular Google Shopping campaigns, and we’ve seen some instances where Smart Shopping could only perform better than our setup by using pricing data.
I think it weighs the price competitiveness of each product into the auction, especially if there is no other data.
Pricing data for Search/Shopping campaigns is extremely useful. Not having to bid for products where you are significantly more expensive can be a game-changer. Smart Shopping seems to be able to use this data (they have it) in their bidding. If that’s true, then Smart Shopping has a distinct advantage.
That’s just one example of a bidding factor that we don’t have access to in the interface or API (as of this writing). So, if you’re struggling with getting Google Shopping profitable for certain products, then maybe it’s as simple as taking Smart Shopping for a spin.
Oh, this is so nice. People mess up Shopping campaigns all the time.
You would be surprised at how many times we opened accounts where some product groups were missing, or priority settings were set incorrectly, etc. Smart Shopping campaigns are tough to mess up, which is why it’s great for those who don’t have a ton of experience yet.
Smart Shopping automatically opts into Google Display and YouTube. There isn’t any specific magic going on, though. It tries to find the same type of users that have converted on Search, and target them via Display.
For some product types, like D2C, this can be a nice addition of revenue. Large retail stores can also see a 10% increase in revenue if it pans out, which for large accounts is something that is really nice to see.
Many who opened this article might have thought they’d see the typical rant on Smart Shopping and see a huge list of cons with maybe a pro or two.
The truth is that I do find that there are more pros than cons with Smart Shopping, but in my opinion, the cons significantly outweigh the pros.
It all starts with the lack of search data, which is detrimental to your other work on the account.
You can’t see what search terms your campaign is triggering. Smart Shopping will analyze the performance on the search term data and bid higher or lower on the individual search terms.
This is paradoxical because it needs data to determine good or bad search terms. But if you have ever looked through a search term report for Google Shopping campaigns, then you will know how many search terms you can proactively exclude without needing to get “sufficient data” first.
Furthermore, the loss of search term data makes it hard to use that data for your Search Ad campaigns. A cornerstone tactic in any large eCommerce account is to cross-reference search terms in Google Shopping with your keyword covered in your regular search campaigns.
That tactic goes out the window when you use Smart Shopping.
Smart Shopping automatically targets users across Search, Display, and YouTube. You can’t tell it not to, and you can’t see how much of the traffic comes from where.
For smaller advertisers, this might not be a big deal. But for larger advertisers with multiple marketing channels, this is a dealbreaker for me. We need to be able to know how much of our budget is going to display remarketing and how much is going into product ads in Google Search (i.e., the regular Shopping ads).
If all we do is focus our Smart Shopping campaigns on remarketing audiences, then our campaigns will suffer a slow death, which is the same thing if we just rely on a huge Facebook campaign.
Again, it might be smart to feed off our Facebook Ads traffic. But we need to understand it. Otherwise, we might turn off our Facebook Ads, and then what happens to our Smart Shopping campaigns that are living off our remarketing audience?
Potential disaster. And the bigger you are, the bigger the disaster.
Google is not good at identifying which users go from mobile to desktop to complete a purchase. Google’s cross-device metrics will say that out of thousands of purchases, only a handful of them went cross-device even if that might not be actually the case.
That might be the case for some accounts, but not all. Facebook Analytics is a lot more trustworthy here, and it helps us set the right ROAS and profit targets for mobile and desktop traffic.
You may be thinking, “Ok, Andrew. I hear you. But why don’t you just split Smart Shopping up in two different campaigns with different ROAS targets?”
Which is annoying 🙂
This is such a major point that I need to make it twice.
Especially for large eCommerce stores, you will never be able to get all keywords in the first try. If you don’t use search term data from your Dynamic Search Ad and Shopping campaigns, then you are missing out on exposure.
Uff. This might be the biggest reason why we change from Smart Shopping to “manual” campaign structures. About 50% of the clients we accept in SavvyRevenue are running Smart Shopping today.
In all cases, we propose two management fees—one with Smart Shopping and one with our strategies. The fee structure where we use Smart Shopping is lower than our regular fees, as there is less legwork (more on this later).
As of this writing, we’ve never had a case where they stuck with Smart Shopping.
The reason for this is that the second something goes wrong, then there is not much we can do to fix it.
What happens if your conversion tracking drops out or is wrong (even just a little) for a few days? Smart Shopping traffic drops drastically, and takes a couple of weeks to recover. That’s expensive for large stores.
What if your competitors are running a promotion that you can’t follow? Smart Shopping takes a few days to catch this and gets expensive in the long run.
You need to push certain products/brands/categories proactively because you’ve become more competitive, or you strategically need a category/brand to increase revenue? You can’t without breaking it out into separate campaigns.
For these reasons and a couple of other scenarios, they always —over time —opt for a regular Shopping campaign setup.
Some of these insights are directly from users themselves. This one, in particular, is one I’ve seen a couple of times on Twitter.
Smart Shopping runs with a set amount of conversions, and then a seasonal change happens, which results in a lower amount of conversions. Seeing that the bid format is “Maximize Conversions” (within the budget), Smart Shopping will try to find other avenues to increase conversions.
Sensing that it can’t get more profitable conversions out of Search, then it will start jumping into Display.
This is using Responsive Display Ads. For Smart Shopping, these ads are super ugly. The chances of getting additional profitable conversions from that display ad format are very low. There is a reason why it became an industry-wide best practice to turn off Display partners in Search campaigns as early as 2008 (yes, I’m that old).
Now, Google is saying that they can do it better. And they probably can. So they opt your Smart Shopping campaigns into the Display Network.
Personally, I think this is great when you have a mountain of conversions, solid audience data, and in addition to Search.
But as a Hail Mary tactic to try to go from 50 to 100 conversions? Not gonna happen. But you can’t turn this off in Smart Shopping. So you have to take it.
Just a couple of quick nuggets of information that I think you should know:
There’s no need to break up your campaign into various ad groups or product groups, unless you want the insight. Google will not bid differently if you break out your product groups. So no need to do this unless you want to have the insight for how various brands/product_types/custom labels perform.
I’ve seen advertisers break out Smart Shopping product groups at different margin levels. Good idea for the insight, but when I hear it’s to help Google optimize, then it makes no sense.
Smart Shopping is an “Ultra Priority” and Overrides All Other Shopping or Dynamic Remarketing Campaigns. If you have the same products in Smart Shopping and regular Shopping or Remarketing campaigns, then Smart Shopping will almost always be prioritized.
There are a few instances where it’s not true, such as if you have a much higher bid in your regular campaigns, or if you’re running a different CSS engine.
Never Use Smart Shopping Initially If You Can Avoid It. Because you lose the search data, then I never recommend starting accounts with Smart Shopping. The search data is simply too valuable.
Advertisers who lack the insight to build and optimize regular Google Shopping campaigns should use Smart Shopping campaigns. If you aren’t doing a good job running regular Shopping campaigns, then Smart Shopping will almost exclusively be a great addition to your account.
Despite popular belief, there are ways to optimize Smart Shopping. They’re not evident, and you’re not supposed to optimize them per se. Google is supposed to take care of everything 😉
I’ll list some of the things we’ve done to optimize Smart Shopping, and improve its performance.
You can choose between two bidding methods in Smart Shopping:
The two bidding methods have subtle differences, but they work a bit differently in reality.
To optimize your Smart Shopping campaigns, try changing between the two methods to find which works best for your products.
If you’ve set a Target ROAS, try changing it up and down every two or three weeks to boost revenue.
We’ve seen surprisingly good results by setting Target ROAS 100-200% below our actual target. In one instance, we actually increased revenue by 50% while still hitting our Target ROAS after we changed from 700% Target ROAS to 500% Target ROAS.
The theory here is that Google tries to predict the value of a conversion from various products. Seeing that Google “has to” hit 700% ROAS, then it’s more constrained in what auctions it can enter. By loosening the target, you can allow Google to enter more auctions and thereby convert better.
If you haven’t set a Target ROAS in your Smart Shopping campaigns, you can play with changing the assigned budget.
If you increase the budget, Google will start entering more auctions.
If you decrease it, Google will enter fewer auctions.
Increasing and decreasing the budget can be a clever way to bid higher or lower despite not having a direct ability to change bids.
Just be careful. I wouldn’t increase budgets by more than 25% at a time, depending on the budget you have today. Google will spend the budget if you don’t set a Target ROAS.
You can exclude products from your Smart Shopping campaigns by excluding them on the product group level.
If you know that different products/categories/brands should run at different ROAS levels, then it makes sense to split them into various Smart Shopping campaigns with different ROAS targets.
Just don’t do this too granularly. Algorithms live off data, so the more you split up your data, the less likely you are to succeed with their automated setups.
Not making a profit from $10 products? Exclude them.
Shipping taking too long for certain brands? Exclude them.
Essentially, if you know that certain products will not convert well no matter what, then exclude them. That way, you don’t have to wait for Google to do it for you.
This is especially true in apparel. Google can’t tell (yet) how many sizes are left for a specific product. If the least popular size is the only one left, Google will still try to sell that product aggressively.
Having a rule in place in your feed optimization tool to exclude low-stock products can, therefore, be a very good way to help Smart Shopping deliver better results.
And lastly, improving your Google Shopping feed.
I will not go into too much depth as we have several articles and webinars on this topic, but anything you can do (to a certain extent) to optimize your Google Shopping feed will help improve your Smart Shopping results.
Yes and no.
Don’t pay full price, or the regular percentage of ad spend. There isn’t as much work as we’d normally have for another campaign.
But as I mentioned above, there are still areas to optimize within Smart Shopping, but they are not as extensive as the regular approach, which requires quite a bit of work.
As a result, the math becomes based on how much you can save on Smart Shopping management.
Our mantra at SavvyRevenue is that we need to outperform Smart Shopping by more than it costs to have us manage it for it to be worth us running regular campaign setups.
Because if we outperform Smart Shopping by 5%, then it’s often not enough to offset our management fee, which ranges from 8% to 20% based on spend. However, if our client values not having to worry about the day their tracking (unfortunately) stops working, then they will happily pay that little bit extra.
But what you absolutely shouldn’t do is pay $10,000 for setting up Smart Shopping, which we’ve seen examples of, and then a ludicrous amount in monthly fees. If anybody is ever in doubt about whether they have a fair agreement they can always write to me directly (email@example.com). You’ll just get an assessment of your agreement —no pitching from my end (we don’t need to).
Some people have proclaimed that Google’s success with Smart Shopping is a sign that, within a few years, Google will be able to automate all of Google Ads for eCommerce (and other industries).
I highly doubt it.
Dynamic Search Ad campaigns should be in any eCommerce account but are way too volatile to be standalone.
Google’s Automated Ad Suggestions are horrible at best.
Smart Bidding is hit-or-miss based on various scenarios.
But what I do think is that Google’s automation will become better and better for small businesses. I wrote about this in my critique of AdWords Express back in 2013; that if the “spillage” from the automated campaign formats was less than it would cost to have an agency handle the account, then AdWords Express was actually the better choice.
It’s that bar that I believe will be set higher. Google’s automation will become better and better, so the level at which you will need an agency will become higher and higher.
I predict that Google’s automation will weed out many of the worst PPC practitioners out there. If you don’t have any specific intellectual property, framework, or anything unique about what you do, then Google’s automation will swallow you simply because you will not be able to outperform Google’s automation enough to make it worth it for advertisers.
The rest of us will be juuuuust fine. We might execute less and therefore open us up to more clients per person, but as this article indicates, then even when it appears that nothing can be optimized there are things we can do to help the black boxes.

Thanks for the great overview!
I just wanted to add that we may get a hint on how much of the traffic is remarketing traffic, if we look at the Google Analytics data for “new users” vs. “returning users” for our Smart Shopping campaign.
If we then see that for example 70% are “new users”, everything is fine. If the proportion of remarketing becomes too high, we can react accordingly and consider whether Smart Shopping is the right thing for us.
That’s a great tip, Arne.
It would definitely give some advertisers a bit more tranquility knowing that they’re not just putting money into remarketing.
Google is also running a beta for differentiating the targets for new customers vs existing customers, which could definitely help as well.
Still – at higher levels of ecommerce it’s simply too risky to leave in the hands of a blackbox.
Thank you so much for all the great insights! I’ve run both Smart Shopping campaigns and Standard Shopping for more than 20,000+ SKUs and compared their performance in the past year and a half. A couple questions:
1) I’ve noticed that the CPC of Smart Shopping is really low. Initially I thought this is because SSC is very aggressive with Display Remarketing. However, after pulling the Shopping placements reports, I found out Display Remarketing only takes up around 3% of the total spend each month, which means the majority of the budget is spent on Google SERPs like Standard Shopping does. Do you have any insights into why SSC has such a low CPC across the board (which leads to a really high ROAS, compared to Standard Shopping)?
2) I built out Standard Shopping with the best practices I learnt from your other articles (splitting campaigns by Generic Searches and Brand Searches with campaign priority, optimizing product feed structure etc.). I’ve used both manual CPC and ECPC. The ROAS delivered by Standard Shopping is usually only 60% that of SSC for the same category and products (e.g. $9 vs $15). I don’t think there’s anything wrong with the setup and bids. Is this something that you’ve encountered before? What’s your advice for outperforming SSC with Standard Shopping?
Though I really want to use Standard Shopping because SSC is a big blackbox, SSC has a really high ROAS which makes me hesitant to switch back to Standard Shopping.
1) SSC is a lot better at getting the right products into the right auctions than standard Shopping for stores with large inventories. We’ve seen this a couple of times as well.
With a high SKU count the challenge with Shopping is that if you get 1 click per product at $0.5 each you’re still spending $10,000 per day without getting to any significant volume on any one product.
SSC seems to know what products to advertise for, and our theory currently is that they are including price benchmark as a bidding signal. Our cases indicate this.
In terms of the low CPCs then that’s very common for stores with a large SKU count. The entire Google Ads tactic can initially just be to set a super low bid and you’ll make money. The harder part is scaling that kind of setup, which can be really hard.
2) If SSC is outperforming your standard setup, then do the following:
Find the categories/products that aren’t doing well in SSC and create standard shopping campaigns for them to boost performance.
Also, try to find another factor than search term. Sometimes brand vs generic search terms is not that significant a factor and then the split actually doesn’t work that well.
Other factors can be products on sale, new vs old, cheaper vs more expensive, bestsellers vs others, high margin vs low margin.
Thank you so much for your reply Andrew 🙂 I’ve learned heaps from you!
Great read! I think it was pretty balanced with the pros and cons.
One thing I will say as to my personal experience with G-shopping:
For our brand, we started on standard shopping and once I saw all the keyword data I quickly realized the only thing that works is branded search for us. Non-branded keywords performed horribly.
Once I got into smart shopping, I knew pretty much branded keywords did well and nothing else did well, so I made a limited budget + a 500%+ ROAS target to keep things “reigned in” — I’ve been pretty satisfied with the results from the strategy.
All these smart campaigns – Truly what it lacks is an human touch. Hmm touch of an expert human for that matter.
Your pros kind of makes me smiling and cons makes me thinking.
Regarding the search terms data, it’s a crime being done by Google. If they are really smart, they would have provided the search term data (atleast portion of it) in a read only mode to help us get insights from.
Let them make optimizations based on the search terms data, but be more transparent.
I hope at a point where they really becomes smart and confident, they provably do that.
nice summary. Really helpful. Still can’t make up my mind about whether I should switch to smart shopping but this was a good read and very informative Thanks!
What would happen if one same product is included in two different Smart Shopping campaigns? Do we need to exclude the product first in one Smart Shopping campaign and then include it in a new SSC?
Thanks for the great article.
Yes, that would be the way to do it.
Google states that running separate Smart Shopping campaigns isn’t smart though.
We have seen both cases though, but if you suddenly see performance drop in the new campaign, then you might want to move products back to the original campaign.
Andrew, thank you so much for this incredibly useful and well-written article. I’ve been running my store for 12 months and grown sales every month, until one day, bam, impressions, clicks, and conversions fell drastically in all my campaigns to almost $0.
What I think caused this:
I have separate campaigns by product type because we need to track performance of different product types. One of our campaigns is a smart shopping campaign. Not surprisingly, it’s the most profitable.
So, at the beginning of September, we decided to move our next 2 most profitable campaigns from manual shopping to smart shopping. Within 2 weeks all 3 of these campaigns fell to almost $0.
I panicked, but having read your article really helped.
I believe now that creating 2 more smart campaigns cause google to de-prioritize my first smart campaign, and begin reevaluating how to work with all 3.
Can you please clarify:
-Since I need to get sales back on track FAST, is it reasonable to keep the original smart shopping campaign as a smart campaign, and move the other two back to manual? (I would rather move all to manual, but frankly, we do not yet have the budget for a great ad agency, and I do not have the time to manage manual campaigns on my own, so it’s nice to get the easy sales from smart shopping for now)
Thank you very much again!
I am curious to why sales dropped to $0. Dropping to $0 is usually an indication is something being wrong (yeah, not rocket science, Andrew :), but it means that maybe something is underlying wrong and you need to go in a separate direction.
But technically, moving the other to back to manual should do the trick.
When in doubt, revert changes and see if things don’t pick back up 🙂
A little late to the party I guess, but very nice blog post as always from you 🙂
I have question about one of your replies in this post.
You write “SSC seems to know what products to advertise for, and our theory currently is that they are including price benchmark as a bidding signal. Our cases indicate this.”
Is this still your theory? Because Google themselves says that smart bidding also use Price competitiveness as a signal.
So smart bidding (standard shopping with tROAS) should be equal to SSC on this specific signal. Is that what you also see or?
Reason I ask is because I am moving away from SSC due to performance max and are researching what I am going to miss out on when swapping SSC for standard shopping on tROAS.

Yeah, it was the theory back when we wrote the article on Smart Shopping but it is 100% included in the general Smart Bidding algorithm now. So I guess we were correct early on (which we also had confirmed behind the scenes from Google).
Technically, Smart Bidding should work the same as Smart Shopping (did) but we just don’t see it. Setting up a single Standard Shopping campaign to take over from a single Smart Shopping campaign doesn’t always yield the same results. Which is very weird, but I have spoken with several other PPC’ers about it and they have seen the same thing.
So there was something in Smart Shopping that Smart Bidding doesn’t provide. You can usually make up for it if you have a use-case for priorities.
