Working with Dardo from Mobile
Dardo is a three-person design studio in Bogotá, Colombia, led by its founder, Nicolás Cerón. We work with companies in Mobile remotely: there is no Dardo office in Mobile. Calls happen on video, in English or Spanish, and everything we agree goes into a written proposal.
Bogotá keeps UTC−5 all year, with no daylight saving time. Mobile is 1 hour behind Bogotá in January and on the same clock as Bogotá in July, so a nine-to-five day in Mobile shares 7–8 working hours with a nine-to-five day in Bogotá.
A project starts with a brief through the contact form, by email to hello@dardo.studio or on WhatsApp. Nicolás replies within one business day with the questions that set the scope. The proposal that follows lists the scope, deliverables, assumptions, exclusions, payment stages, a timeline and the people doing the work, by name.
Quotes typically come in at about half of what comparable US and Canadian studios charge for the same scope. Pricing explains how a quote is built.
What our website speed optimization services include
Every project ends with a Core Web Vitals target per template, measured on real visits, not a Lighthouse score. The proposal names the templates in scope, which of these deliverables apply, who implements each fix and how it is accepted:
- Field-data baseline per template from the Chrome UX Report, Search Console and your analytics
- Lab traces of the slowest templates on an emulated mid-range phone with a slowed CPU
- A fix list ranked by visits affected, metric moved and effort
- A third-party script inventory, each tag with an owner and a decision
- Fixes in your code, theme, CMS or platform settings, or tickets for your developers
- Real-user measurement of LCP, INP and CLS where Google's data is missing
- A before-and-after report from field data, 28 days after the last release
The website speed optimization service page has the full scope, the process and the questions buyers ask.
How fast websites in the United States are on phones
In October 2026, 63.9% of the websites in the United States measured by Chrome's user experience report passed all three Core Web Vitals on phones, according to the HTTP Archive. The platform behind a site moves that number:
| Platform | Sites measured | Pass on phones |
|---|---|---|
| Wix | 34,241 | 88.8% |
| Shopify | 118,272 | 86.1% |
| Squarespace | 40,344 | 82.9% |
| Framer | 1,909 | 82.2% |
| Webflow | 15,239 | 80.9% |
| WordPress | 330,180 | 63.3% |
Speed comes from how a site is built more than from the platform, and Google uses Core Web Vitals in search. The platform speed report has the same numbers for other countries.

- Shiimain (Public data / Territorial intelligence, 2026). 4 days to build, 27 to 30 May 2026.
None of these clients is in Mobile. They are the projects we can show, with their numbers.
Questions before you choose
Does Dardo have an office in Mobile?
No. Dardo is a three-person studio in Bogotá, Colombia, and works with companies in Mobile remotely, on video calls, in English or Spanish.
What is the time difference between Mobile and Bogotá?
Mobile is 1 hour behind Bogotá in January and on the same clock as Bogotá in July. Bogotá keeps UTC−5 all year, so a nine-to-five day in Mobile shares 7–8 working hours with ours.
How much does website speed optimization cost with Dardo?
Each project is quoted by scope in an itemized written proposal in US dollars, with no minimum budget.
How much does website speed optimization cost?
There's no published starting price. The quote follows the templates in scope, the platform, third-party scripts, design changes and who implements the fixes. The audit is priced separately, so you can stop after it and work through the list yourselves.
How fast should a website load?
Google's Core Web Vitals set the bar at the 75th percentile of real visits: the main content should appear within 2.5 seconds (Largest Contentful Paint), the page should respond to a tap or click within 200 milliseconds (Interaction to Next Paint), and the layout shouldn't shift by more than 0.1 (Cumulative Layout Shift). Each is measured separately on mobile and desktop.
