Website Performance and Marketing Conversion: Key Findings
Converting users into customers is almost always easier said than done.
The average eCommerce website converts only about 1.6% of visitors, according to Statista.
This is certainly an underwhelming data point, and it also suggests marketers may be missing the full picture when it comes to performance.
“Ads are really important, but they're only the first step,” says Jeff Finkelstein, founder of Customer Paradigm, a Boulder-based interactive marketing agency.
Why? Too many still focus on traffic growth and not enough on what happens after a visitor enters the site.
In episode No. 130 of the DesignRush Podcast, Finkelstein explains why a company’s website ultimately determines whether marketing traffic converts.
When critical components are missed, the result is wasted advertising budgets, poor performance for current (and even future) campaigns, and stalled growth in the long run.
In this information-packed episode, Finkelstein explains:
- Why the website experience ultimately determines whether traffic converts
- How poor website performance can increase advertising costs
- How traffic surges can expose infrastructure weaknesses
- Why organic visibility supports sustainable growth
To attract attention without wasting marketing investment on websites that fail to convert, don’t miss this conversation.

Ads Capture Attention, but Websites Convert Visitors
Advertising helps companies capture attention, but conversion happens once someone arrives on the website.
That difference is where many businesses struggle.
About 70% of shoppers abandon their cart before completing checkout, according to the Baymard Institute’s checkout usability research.
With so many lost sales, it seems companies underestimate how critical the website experience is once someone arrives on the website.
Finkelstein puts it this way:
“So, I think that the trick is yes, an ad grabs your attention, but you have to nail it when they come to the site with something that is going to convert them.”
For this reason, businesses need to cater to online shoppers and aim to create a seamless website experience.
This involves answering key consumer questions, such as what the product actually does, whether the price makes sense, and whether other customers have had success using it.
Without meeting user expectations, even the strongest advertising campaigns can struggle, especially if the website’s setup does not guide visitors toward a clear decision.
“If you don't have a good way to catch people and convert that sale, it's just burning money on ad spend,” Finkelstein says.
What’s the main takeaway?
Create a confusing consumer journey, and risk losing conversions.
Poor Website Performance Can Increase Advertising Costs
Website performance influences more than just user experience.
It can also shape how efficiently companies spend their advertising budgets, since search platforms analyze what happens after someone clicks an ad.
To put it simply, when visitors leave quickly, it signals that the page failed to meet expectations.
Over time, these negative signals affect how platforms evaluate the quality of the site and the ads connected to it.
“So, not only are you burning ad spend, you're pissing off customers, but if you have a site that sucks and people bounce and don't buy, Google knows that and your future advertising is going to cost more,” Finkelstein says.
For businesses competing in expensive advertising markets, the result can be significantly higher advertising costs.
In practice, the impact appears in several ways across marketing teams and customer journeys.
It can lead to a host of problems, including:
- Higher cost per click on advertising platforms
- Lower quality scores on search campaigns
- Declining conversion rates after visitors arrive
- Frustrated customers who leave the site quickly
- Reduced trust in the brand experience
When one or several of these issues occur, advertising platforms treat the site as less relevant to the audience searching for those products or services.
As a result, businesses can end up paying more for the same traffic they once acquired at a lower cost.
That’s why the website experience and marketing campaigns must work together. That way, companies have a better chance of converting attention into lasting customer relationships.
Traffic Surges Can Expose Infrastructure Weaknesses
Major marketing campaigns have huge potential for generating sudden traffic, and that's exactly why websites need to be set up correctly.
If they aren't prepared to handle that demand, the surge in visitors will quickly expose weaknesses in the system.
“Something as simple as sending a huge surge of people, like 50,000 people to your site all at the same time. That's going to cause a site to crash unless you do a lot of planning in advance for it,” Finkelstein says.
But even if the website manages to stay online, the sudden influx of orders and inquiries can overwhelm the business and frustrate customers.
“And once you do that, you're not likely to get them back,” Finkelstein adds.
When a campaign drives more traffic than a site can handle, unchecked issues often result in the following:
- Pages take longer to load
- Orders pile up faster than systems can process them
- Support teams struggle to keep up with customer questions
When these kinds of issues occur, customer trust declines quickly, resulting in damage to a company’s reputation, especially during periods of high demand.
For example, when Ticketmaster’s systems crashed during the presale for Taylor Swift’s Eras Tour tickets, the backlash triggered widespread criticism and even congressional scrutiny of the platform’s reliability.
Additionally, Finkelstein has also spoken about the importance of resilient infrastructure in other interviews, including a recent discussion on fault-tolerant API design and system reliability:
Large Ad Budgets Can Hide Inefficiencies
Organizations with large advertising budgets sometimes overlook inefficiencies that smaller companies would notice more quickly.
When significant funds are allocated to advertising, wasted clicks or weak campaign performance can appear insignificant in the broader marketing spend.
This environment allows deeper problems to remain unnoticed for long periods of time.
“If you're spending $5,000 a month on advertising, or $25,000 a month, or $100,000 a month, it's really easy not to worry about some of the outliers,” Finkelstein says.
However, small inefficiencies can accumulate as campaigns continue running. Over time, what may seem like insignificant issues can reduce overall marketing efficiency and increase the cost of acquiring each customer.
Heavy reliance on paid advertising can also create long-term risk. When the budget stops, the traffic often stops as well. Organic visibility, on the other hand, can continue bringing visitors to the site over time.
That’s why, sustainable growth requires attention to both advertising performance and the systems that support long-term discovery.
Who Is Jeff Finkelstein?
Jeff Finkelstein is the founder of Customer Paradigm, a Boulder-based interactive marketing agency that helps organizations improve digital performance through eCommerce development, search engine optimization, and web marketing. Through his work, he has supported brands including Xcel Energy, 3M, Level 3, and BP in building stronger online visibility and scalable digital platforms.
Organic Visibility Supports Sustainable Growth
To reduce reliance on paid traffic over time, Finkelstein again points to organic visibility.
This means, instead of pouring everything into ads, businesses can invest in creating high-quality, useful content for the sake of achieving strong search visibility.
This is so that customers can find answers to their questions more efficiently and easily.
One long-term client of Customer Paradigm followed this approach by allocating roughly 25% of their budget to organic content.
“And now that translates into about $28,000 a month in inbound traffic that they would otherwise have to pay for,” Finkelstein says.
Relevant content continues to play an important role as search technology evolves.
For many businesses, that kind of long-term visibility can quietly become one of the most valuable sources of growth.
Understanding Customer Needs Remains Essential
Search platforms, artificial intelligence, and digital tools influence how customers discover products and services.
Finkelstein explains that successful marketing still depends on understanding the customer first.
“The trick as a marketer is to get inside the head of your end user,” Finkelstein says.
When companies design their websites, messaging, and systems around real customer needs, the entire marketing process becomes more effective.
This can result in:
- Clearer product information for visitors
- More relevant solutions from internal teams
- Greater customer confidence in the brand
“If you focus on the needs of that end customer first, everything else is going to follow,” he says.
Case in point?
Reliable technology and thoughtful customer experience determine whether that attention becomes lasting business growth.
