We work with companies in the United States remotely: there is no Dardo office in the United States. 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. New York is on the same clock as Bogotá in January and 1 hour ahead of Bogotá in July, so a nine-to-five day in New York shares 7–8 working hours with a nine-to-five day in Bogotá. A project starts with a brief through the [contact form](https://dardo.studio/en/contact/?service=website-speed-optimization), 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](https://dardo.studio/en/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](https://dardo.studio/en/blog/fix-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](https://dardo.studio/en/services/website-speed-optimization/) 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](https://httparchive.org/reports/techreport/landing). The platform behind a site moves that number: __How fast websites in the United States are on phones__ | 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](https://dardo.studio/en/tools/website-platform-speed-report/) has the same numbers for other countries. ## Work you can check Projects from 2026, each with its published result: - [Janus Observatory](https://dardo.studio/en/work/janus-observatory/) (Science / Interactive storytelling, 2026). −47.9% 3D models: 8.2 MB instead of 15.8 MB. - [Hyper](https://dardo.studio/en/work/hyper/) (AI / Customer intelligence, 2026).

These are the projects we can show, with their numbers. ## Questions before you choose **Does Dardo have an office in the United States?** No. Dardo is a three-person studio in Bogotá, Colombia, and works with companies in the United States remotely, on video calls, in English or Spanish. **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. ## Sources & further reading Sources behind this page, with further detail from the original publishers. - [HTTP Archive technology report (Core Web Vitals by platform and country)](https://httparchive.org/reports/techreport/landing) · httparchive.org - [Google Search Central: Understanding page experience in Google Search results](https://developers.google.com/search/docs/appearance/page-experience) · developers.google.com - [web.dev: Web Vitals](https://web.dev/articles/vitals) · web.dev - [web.dev: Interaction to Next Paint becomes a Core Web Vital on March 12](https://web.dev/blog/inp-cwv-march-12) · web.dev [Dardo](https://dardo.studio/) · [Speed by city](https://dardo.studio/en/website-speed-optimization/) · United States ## Start with a brief Send what you need, your languages and your deadline.
