You increase your ad spend on Google, Meta, or Mercado Ads, but sales aren’t growing at the same rate. The typical reaction from a marketing team is to ask for better optimization. But the question a CEO, CFO, or Growth Manager really needs to answer is this: What are we teaching the algorithm to recognize as profit, and does that number appear on the income statement—or only in the campaign dashboard?
This is the question we hear most often from those who decide on acquisition budgets in Latin America, and the answer lies in four specific areas: how ad platforms are fed, how closely SEO and automation are tied to those campaigns, what the website does with the traffic that’s already been paid for, and what data is used to make decisions. These are the same four key areas we’ll be breaking down in the upcoming Known Online webinar— and the ones we work on every day with e-commerce and B2B teams across the region.
Paid Media with a Focus on ROAS: Google, Meta, TikTok, and Mercado Ads
The first decision isn’t how much to invest, but what the algorithm is learning in terms of return. Performance Max, Advantage+, and Mercado Ads’ automated campaigns no longer follow the step-by-step setup configured by a media team: they make decisions based on the data they receive, and that data may be miscalibrated without anyone noticing it in the weekly report.
That’s why ROAS The metrics shown by each platform can rise even as actual profitability declines: they are calculated based on conversions that the platform itself defined and attributed, not on the margin shown on the income statement. If the conversion signal triggers before payment is confirmed, or if the product’s cost was never passed on to the algorithm, the platform reports a high ROAS while actual profit remains flat or declines. This is also why Performance Max or Advantage+ sometimes misallocate the budget: these systems optimize based on the signal they receive, not on the business’s margin. If the configured conversion does not reflect a confirmed sale, or if the actual margin value per product is not transmitted, the algorithm directs the budget toward where it is easiest to convert, not toward where the business makes the most profit.
When we audit an account, this is the first thing we look at—before even touching on bids or audiences—: what drives conversions and what margin comes with that signal. The addition of channels like TikTok introduces another variable into that decision, because it doesn’t capture existing demand—it generates it—while Mercado Ads operates on high purchase intent and data specific to its ecosystem. Deciding what role each channel plays and against what criteria it should be evaluated is a decision that belongs to the person who looks at the business as a whole, not to the person who manages each platform separately.
SEO and Marketing Automation: The System That Works After the Click
For a Growth or E-commerce Manager, the fundamental question is how much of the business is exposed to a single source of paid traffic that the company does not control. SEO doesn’t replace paid media in the short term, but it reduces that dependence in the medium term, because the traffic it generates doesn’t disappear when spending on campaigns is cut.
The way we integrate both channels isn’t a generic content plan: it involves organically ranking for keywords that already convert in Search and have a high, sustained cost per click, and optimizing the same campaign landing pages so they get indexed—rather than maintaining a separate organic site from the one that receives paid traffic. Every organic ranking gained for a high-CPC keyword represents budget that the company no longer needs to spend on that same keyword—a savings that directly impacts the cost of acquisition.
Marketing automation addresses the other half of the same decision: it works with the leads that advertising has already generated, and that acquisition cost has already been paid. Simple, well-segmented workflows— abandoned cart recovery , welcome messages by interest category, and reactivation after 90 days without a purchase—determine whether that customer base will buy again without requiring an additional media budget. For those managing the growth budget, it’s the LTV lever with the lowest incremental cost available.
CRO and UX/UI: How to Convert the Traffic You’re Already Paying For
A high CTR and a low cost per click are signs of media efficiency, not business efficiency. If the site converts 0.6% of the traffic you’ve already paid for, those metrics are funding visits that never turn into sales—and that’s a problem that needs to be solved on the site side, not the campaign side.
When we review a funnel with a focus on CRO, there are four recurring pain points. The first is consistency between the ad and the landing page: if the message, image, or offer that drove the click isn’t replicated on the landing page, some of the traffic will bounce before reading the rest. The second is unnecessary steps and fields on the checkout: Every extra field on the payment form is an opportunity for customers to abandon the process. The third factor is the available payment options: expanding them reduces friction right when the customer has already decided to buy. The fourth—and the one most underestimated by teams that don’t measure it—is the Mobile loading speed: Every additional second reduces conversion rates by between 4% and 7%, according to Google’s retail benchmarks—a penalty that hits twice, in terms of cost per click and abandonment, right in the channel where more than 60% of campaign traffic is currently concentrated.
Increasing the conversion rate from 1.2% to 1.8% on a site with stable traffic is equivalent to generating 50% more sales with the same media budget. For a Sales Director or Performance Manager, this is the strategy that delivers the greatest immediate return on already committed spending, because it doesn’t require any additional investment.
Analytics and Data: Measure Effectively So That the AI and teams can make better decisions
None of the three decisions mentioned above can be made correctly if the source data is incorrect. Google attributes the sale to Google. Meta attributes the sale to Meta. Mercado Ads does the same. When added together without correction, these three reports can triple the actual ROAS, because each platform is credited with the entire sale under its own last-click model.
This technical adjustment is called multitouch attribution: instead of attributing the entire sale to the last click within a single platform, it distributes credit among the channels that actually played a role in the customer journey. It’s the model we use to show a CFO a ROAS figure that holds up against the ERP, not just against each platform’s dashboard.
There is a second factor that determines how complete that data is: Enhanced Conversions on Google and CAPI on Meta. These are mechanisms that transmit first-party data from the advertiser to improve the coverage and accuracy of attribution in an environment with fewer and fewer third-party cookies. Without them, a growing portion of actual conversions goes unrecorded, which distorts both ROAS reporting and the learning of the automated bidding algorithm—the very same signal problem addressed at the beginning of this article. Implementing them correctly is, in practice, what connects the measurement decision with the paid media decision: a clean layer of data is what allows both the platforms’ AI and the management team to make decisions based on the actual business—not on what each channel prefers to report about itself.
Four Decisions, One System
Paid Media, SEO and Automation, CRO and UX/UI, and Analytics aren’t four separate projects: they’re four decisions that a single business committee—comprising the CEO, CFO, and the Marketing, E-commerce, Growth, Performance, or Digital Manager—must make in a coordinated manner, because each one influences the outcome of the other three. This is exactly the roadmap we’ve put together for Known Online’s upcoming free webinar, designed for those who need to increase sales without proportionally increasing their investment, identify where budget is being wasted, and prepare for an advertising landscape that’s becoming increasingly automated by AI.

FAQs
Who should have the authority to redefine what constitutes “a sale” for the algorithm? The performance team can implement the change, but the final definition should be approved by finance: it’s a decision that affects reported margin, not just campaign settings.
How often should you audit the conversion signal and the margin used by the algorithm? At a minimum, every time the catalog, product cost, or checkout process changes. In addition, a quarterly review prevents a poor configuration from going unchecked for months.
Does SEO compete with paid media for budget? It doesn’t compete for the same budget; it competes for the time of the team that implements it. That’s why it’s best to prioritize keywords that already have a high and consistent CPC in paid media: these are the ones that deliver the fastest return when they move to organic search.
How long does it take to see results from SEO compared to paid media? Paid media has an impact within days; SEO builds rankings over months. The decision isn’t to choose one or the other, but to maintain both in parallel while organic traffic matures, so as not to be reliant on a single channel in the short term.
Does enabling Enhanced Conversions or CAPI guarantee that ROAS reflects actual profitability? Not on its own. These are mechanisms for transmitting data, not for defining what counts as a sale. If the conversion signal continues to trigger before payment is confirmed or without a profit margin per product, the tool merely transmits a number that was already miscalibrated with greater precision.
