Free Google Shopping CSS Alternatives: Why I Left Producthero and Chose Bidnamic

I'd used Producthero for years. It did the job, it was cheap enough that I never thought particularly hard about it, and switching CSS providers wasn't something worth spending time on.

Then Producthero became part of Channable.

Channable acquired Producthero in May 2025, and Producthero has since evolved into Channable's wider ecommerce platform. Channable's current standalone CSS Standard product costs €29 per merchant per month, with additional optimisation tools such as Title Optimizer, Labelizer Lite and Price Benchmark Lite included.

None of that is necessarily bad value if you use those tools.

I don't.

I essentially wanted the CSS.

That prompted a very simple question: why am I paying for a Google Shopping CSS at all if somebody else will provide exactly the part I need for free?

So I looked around.

Why use a third-party Google Shopping CSS?

If you're already familiar with CSS, skip this section.

A Comparison Shopping Service sits between your Merchant Center and Google's Shopping auction in eligible European markets. Google operates its own CSS, Google Shopping, but advertisers can instead associate their Merchant Center with an independent CSS partner.

The attraction is Google's CSS pricing mechanism. With Google's own CSS, a margin is deducted before the advertiser's bid enters the auction. Third-party CSS providers can therefore give the advertiser more effective bidding power for the same amount of money.

You don't normally need to rebuild your Shopping or Performance Max campaigns. Your Merchant Center, product IDs and historical performance remain in place; the visible difference is usually that your Shopping ads say “By [CSS provider]” instead of “By Google.” Bidnamic, for example, explicitly says that switching CSS leaves product IDs, historical performance and campaign structure intact.

If you're spending any meaningful amount on Google Shopping, using a third-party CSS is one of those optimisations that is difficult to argue against.

The question is whether you need to pay for one.

Producthero and Channable made me look around

Producthero had become something I barely thought about. That is probably the ideal state for infrastructure like this.

Channable now charges €29 per month per merchant for CSS Standard, or €348 a year. It isn't simply selling a CSS: the plan bundles several Shopping optimisation tools alongside it.

But if all you really want is the CSS benefit, €348 a year suddenly looks quite expensive when competitors are offering the underlying CSS for nothing.

That was the beginning of my search for a free Producthero alternative.

I found two serious free options, several inexpensive paid ones and one important catch that isn't obvious from most CSS comparison articles.

Bidnamic: free CSS from an established Shopping company

The first one that interested me was Bidnamic.

Bidnamic offers its CSS completely free of charge. Its site explicitly says you do not have to use Bidnamic's paid management or technology products and that any eligible ecommerce retailer can use its CSS. There is no contract for the CSS, and merchants can transfer back to Google or another provider later.

That immediately made it more attractive than paying several hundred euros a year purely for a CSS association.

It also had something the newer free providers didn't: a decent footprint.

This matters more than it might seem. You're associating a client's Merchant Center with another business. Saving €29 a month isn't worth very much if I have no idea who that business is or whether it will still exist next year.

Bidnamic has been around long enough and has enough visible clients, employees, content and industry history that I was comfortable with that side of it.

But I found another problem.

Free can mean you're the lead

I contacted Bidnamic because its signup process wasn't completely clear about whether I could use the CSS as an independent Google Ads consultant.

That turned into an interesting conversation.

Bidnamic was refreshingly straightforward about the economics of giving CSS away. It can act as a lead magnet for its wider Google Shopping services. That's completely reasonable. Somebody has to pay for the infrastructure.

The problem for an agency or freelancer is obvious: I don't want to introduce my ecommerce client to another company that also sells Google Ads management and then have its salespeople prospect them.

In my case this wasn't really a problem because I effectively have one ecommerce client, and Bidnamic offered to put the account on one of its alternative CSS instances that its salespeople don't even have access to. That solved it.

And ultimately, that's why I chose Bidnamic CSS.

Should agencies use Bidnamic's free CSS?

If you're the retailer itself, I think Bidnamic is the easiest recommendation of the providers I investigated.

It's established, the CSS is free, and you aren't worried about Bidnamic “poaching” you from yourself.

For an agency or freelancer, I'd ask one additional question before switching:

Can you guarantee that my clients will not be approached by your sales team?

Bidnamic was willing to solve that for me.

I'd ask whether they'll give you the same arrangement.

In fact, I think there's an obvious product opportunity here for Bidnamic: an official agency-protected free CSS, where accounts introduced by agencies are automatically ring-fenced from direct sales activity.

Watch this space. I wouldn't be surprised if they formalise something along those lines because the objection is so obvious once you look at free CSS from an agency perspective.

FeedMax: probably the strongest other free CSS alternative

The other free provider I seriously considered was FeedMax.

FeedMax currently advertises its CSS as free for life, with:

• no subscription fee;
• no setup fee;
• no commission on sales;
• no minimum contract;
• availability across all 21 CSS countries;
• support for retailers and agencies.

Its legal terms define “free for life” as lasting while Google's CSS programme continues and while FeedMax continues operating the current version of its service.

On paper, that is an extremely good proposition.

FeedMax also explicitly says advertisers retain control of their accounts, campaigns, budgets and bidding strategy.

I came close to choosing it.

The complication is that FeedMax also sells its own Shopping optimisation technology, including feed enrichment and predictive campaign products. Its wider site even talks about retaining your existing agency and offers a tripartite NDA, which is reassuring, but it still means free CSS is sitting beside commercial services that could potentially be sold to the merchant.

That's not necessarily a reason not to use it. It simply made Bidnamic's specific promise not to expose my account to its sales team more valuable.

If Bidnamic hadn't given me that assurance, FeedMax would probably have been my next choice.

Shoply: the £/€99-a-year boring option

There's also something to be said for simply paying a small amount and being the customer.

Shoply costs €99 a year, charges no additional CPC or CPS fee, and says it's active across all 21 countries in Google's CSS programme.

That's €8.25 a month.

For a business spending thousands a month on Shopping, it's essentially irrelevant.

This is probably the option I'd choose if I wanted a straightforward commercial transaction and didn't want to negotiate special arrangements with a free provider.

Sign up, pay €99, use the CSS and forget about it.

So although I chose Bidnamic, I have Shoply mentally bookmarked as my fallback.

If I picked up another ecommerce client tomorrow and for some reason couldn't get the same protected Bidnamic arrangement, I wouldn't spend another day researching the market. I'd probably just pay the €99.

Bigshopper: established and deliberately self-service

Bigshopper is another good option if your priority is having a traditional CSS supplier rather than getting the lowest possible price.

Its Basic CSS currently costs €29 per month, with additional countries costing €19 each and a 10% discount for annual billing.

That isn't particularly cheap compared with Shoply, let alone free Bidnamic or FeedMax.

What I liked about Bigshopper was its positioning. It explicitly describes itself as a self-service CSS and says it doesn't manage the advertiser's Google Shopping campaigns. Instead, it has a separate network of agency partners for companies that need campaign management.

If client-channel conflict is your overriding concern, that's a cleaner model.

But at €29 a month I would struggle to choose it over free Bidnamic with the protection I've been given.

What about Vendably?

I also found Vendably, which on paper had possibly the most interesting agency proposition of all.

It was pitching free CSS alongside agency functionality, portfolio management and commercial opportunities from clients purchasing other services.

The issue was simply trust.

It had very little online footprint when I looked. I couldn't quickly establish the sort of operating history and visible company identity I'd want before attaching client infrastructure to it.

It may turn out to be excellent. But there was no need for me to take that risk when Bidnamic already offered the same core CSS benefit and had a much more established footprint.

That's an important part of this comparison that pricing tables miss.

Free isn't automatically better.

A CSS provider is something you ideally choose once and then stop thinking about. Stability and trust therefore have value.

My free CSS ranking

Having gone rather further down this rabbit hole than I originally intended, my position is now fairly simple.

If you're an ecommerce business managing your own Google Ads: I'd start with Bidnamic. It's free, established and you don't have an agency-client conflict to worry about.

If you're an agency or freelancer: ask Bidnamic whether it can ring-fence your merchants from its sales organisation. They did it for me. If they make that an official agency policy, I think it becomes a very compelling option. Connect with them on LinkedIn. That's how I got it.

If you specifically want another free provider: look at FeedMax.

If you'd rather just pay a small fixed amount and have a conventional supplier relationship: Shoply at €99 a year is difficult to argue with.

If you value a deliberately self-service CSS company and don't mind paying more: look at Bigshopper.

And if you're already using Channable's wider feed and optimisation ecosystem, its €29 CSS may still make sense. The point isn't that Channable is overpriced for everything it provides. It's that I wasn't using everything it provides.

The lesson from leaving Producthero

The funny thing is that I was perfectly happy paying Producthero.

It wasn't a major cost and I wasn't actively looking to save it.

The Producthero/Channable change simply made me reassess something I'd stopped thinking about. Once I did, I discovered there were credible companies prepared to provide the CSS component I actually needed for free.

That's often how software stacks accumulate unnecessary cost. A £20 or £30 monthly subscription isn't painful enough to investigate, so it survives indefinitely.

In this case, the investigation was worthwhile.

I've now moved to Bidnamic's free CSS.

My Google Ads strategy hasn't changed. My Merchant Center hasn't been rebuilt. I'm not handing campaign management to anybody else. I've simply stopped paying for a CSS product I can get free from an established provider. The swap just took you a few minutes, and that's it. I don't even have a login for Bidnamic at all. They just give me the 20% discount.

If you're currently paying Producthero/Channable purely to get the CSS benefit, I'd at least look around.

You may discover, as I did, that the best Producthero alternative costs nothing at all. If you do use all the extra stuff, it is well worth it, though. Product Hero and Channable are good products as well, but I moved because I don't use any of the extra stuff. I will always like Product Hero as they introduced me to the world of CSS Shopping and the 20% discount they give you.
