In ecommerce, small data inaccuracies lead to large decision mistakes.
A retailer may overestimate demand and overbuy inventory. An investor may misread growth momentum and miss a breakout brand. A SaaS company may prioritize the wrong accounts and miss out on the right deals.
At the center of many of these decisions sits one core signal: website traffic.
Traffic is often the earliest measurable indicator of real consumer demand, but it is also one of the most difficult ecommerce metrics to estimate accurately.
That is why strengthening website traffic accuracy has been a long-term priority for Charm.
As Alex Nisenzon, CEO of Charm, shares:
"Before Charm, I spent seven years at Similarweb, the industry-leading provider of web traffic data. I have been waiting for the right moment to bring that traffic intelligence into Charm, and I am excited to share that time has finally come."
— Alex Nisenzon, CEO of Charm
Charm has officially partnered with Similarweb, bringing their best-in-class web traffic estimates directly into the Charm platform.
Key Takeaways
Web traffic is one of the strongest signals of consumer interest in ecommerce. It’s often the clearest early indicator that a brand is earning real attention, before that demand shows up in broader distribution or bigger marketing budgets.
There are millions of DTC brands worldwide, and new ones are launched every day. The data needed to understand performance is fragmented across websites, social platforms, marketplaces, resellers, and ad channels.
Charm was built to solve that problem by creating a one-stop shop where retailers, investors, and B2B service providers can get the ecommerce data they need to make informed decisions. Charm tracks 5M+ brands across key metrics, including social signals, tech stack, ad count, resellers, and more. Within that ecosystem, web traffic is a core signal and one of the highest-signal, hardest-to-estimate metrics in ecommerce.
By integrating with Similarweb, Charm is upgrading that core signal inside a much larger intelligence system. This integration means Charm users will access more reliable insight into real customer demand, stronger brand comparisons across categories, and better discovery of emerging brands.
What was previously labeled “Web Traffic” in Charm is now powered by Similarweb’s monthly traffic data, including 12 months of historical coverage. This data brings more consistent measurement across brands and improves how you interpret traffic trends over time, especially when comparing brands within the same category.
The Charm Growth Score and Charm Success Score now incorporate SimilarWeb website traffic data, strengthening the foundation of these rankings.
Because traffic is a meaningful input in both models, upgrading traffic accuracy improves how precisely the platform identifies successful brands and high-growth breakouts.
While this partnership strengthens the traffic signal, Charm’s intelligence engine is built on multiple layers of data. Charm tracks social growth, ad count and ad growth, tech stack, marketplace presence, distribution channels, and global category coverage. SimilarWeb improves the traffic layer, but Charm’s value comes from how that traffic is contextualized inside a multi-signal model.
By integrating SimilarWeb, Charm directly strengthens its scoring engine. Stronger scores lead to better brand discovery. Better discovery leads to better data-backed decisions for retailers, investors, and B2B service providers.
This data went live on the Charm platform on February 17th. You can now see the impact directly inside category rankings and brand profiles.
For example, Charm’s all-category rankings compare brands from many categories side by side based on the Charm Growth Score.
Among all brands from various categories, Rho Nutrition from health and wellness currently ranks #1 with a Growth Score of 100.00 and a Success Score of 98.64.
Inside the brand profile, the web traffic chart shows 12 months of monthly traffic data powered in partnership with SimilarWeb, showing how traffic is a key factor in its overall brand growth.
With traffic data now fueled by Similarweb, you may notice shifts in web traffic values and related scores. Some brands may move up or down in the rankings as the scoring engine recalibrates based on stronger traffic inputs. These changes reflect improved accuracy in the underlying data, not cosmetic adjustments.
From the beginning, our goal has been to provide the most comprehensive and reliable data on ecommerce brands globally. That requires continuous improvement by strengthening every layer of the intelligence stack and partnering with best-in-class providers when it helps people make better decisions.
Integrating Similarweb into Charm is one of those moments. This is not just an addition to the platform. It is an upgrade to the foundation, and it brings us one step closer to delivering the most trusted performance intelligence system in DTC.
