SEO, web development & online stores agency

SEO, websites and online stores that bring clients, not just visits

At 3R Core we help businesses across the U.S. sell more online with three services that work together: we rank you on Google with SEO, build your website and build your online store. Our in-house team works U.S. business hours, and U.S. clients contract and invoice through our U.S. subsidiary. Everything with real measurement, monthly reports and a focus on return on investment, not vanity metrics.

3R Core is an SEO, web development and online stores agency founded by brothers Alejandro and Piero Roque that serves businesses nationwide across the United States. It works three services: SEO, web development and online stores on Shopify or WooCommerce, built by an in-house design, development and SEO team and with no mandatory contracts.

SEO that compounds

Technical foundations fixed first, then content written for real search intent and the internal linking that makes it accumulate. Reported on cost per acquisition, not on rank screenshots.

See SEO service

Web development

Corporate sites, landing pages and bilingual builds, instrumented before launch so the first month of traffic already tells you which page produces revenue. Fast on mobile, structured for search, and handed over in your own accounts.

See web development

Online stores

Shopify or WooCommerce with payment gateway, loaded catalog, state-level sales tax and purchase tracking working from the first order. Built to sell, not just to launch.

We also support you with

Measurement from day one

Analytics and conversion tracking configured before launch, in your own accounts.

Web development with tracking built in

Spanish where it pays

A real indexable Spanish version — usually the cheapest qualified traffic a U.S. business can reach.

SEO services, English and Spanish

U.S. payments and sales tax

Gateway configured and state-level tax calculation working, the piece most commonly left broken.

Online store development

Serving businesses across the U.S.

We work with businesses nationwide, on U.S. business hours, with fixed scopes in USD and contracts and invoicing through our U.S. subsidiary.

Fabián Olea★★★★★

“Me encuentro completamente satisfecho con la agencia. Cuando quise comenzar con la tienda virtual de mi emprendimiento tuve muchas dudas al respecto, ya que soy completamente inexperto en el campo de la programación, pero gracias a ellos pude incursionar en el ecommerce y ampliar el alcance de mi negocio. Se preocuparon por mi marca desde el primer momento, plasmaron mis ideas en el diseño de la página web, me dieron varias recomendaciones para mejorar el posicionamiento de mi tienda e incluso me facilitaron la integración de una pasarela de pagos para facilitar las transacciones dentro en mi página, mis ingresos han incrementado bastante desde entonces. Estoy muy agradecioa con los servicios recibidos y les recomiendo mucho esta agencia.”
