Website development by the Cómon marketing agency
Website development does not end when the design is approved. A beautiful site that brings no enquiries is just a brochure nobody opens. We work as a marketing agency, so we plan the site from the result backwards: what a visitor should do, how many of those actions you need, and how to measure them. The aim is not only web design and development but a tool that pays for itself.
Landing page, business website or online store
A landing page is one page for one action. It is the best format for testing a niche and for ads to a specific service. A business website is needed when you have several services, a longer sales cycle, and when trust and organic search matter. An e-commerce website adds a catalogue, cart, payments and delivery, and needs careful structure because e-commerce SEO depends on it.
What makes a website convert
- a clear offer on the first screen: what you do, for whom and why you;
- a short path to action: a form, a call button, a messenger;
- proof: case studies, reviews, client logos and real numbers;
- fast loading and comfortable use on a phone, where a large share of traffic arrives;
- event tracking, so you can see what works and improve it.
Website and advertising work together
The most common mistake is to run ads to a weak site and conclude that “ads do not work”. We prepare the site for Google Ads and paid social: page structure matched to search intent, GA4 goals and pixels in place. When SEO is part of the plan, we build it into the architecture from the start instead of rebuilding the site a year later.
Basic SEO and speed
Every project includes a logical page structure, headings, meta tags, mobile responsiveness and a speed check. We do not promise rankings, because they depend on competition and content, but we remove the technical barriers that stop search engines from understanding your site.
Common website mistakes
- building the site for yourself instead of the customer, without explaining why you beat competitors;
- overloading pages with effects that make them slow on a phone;
- hiding contact details and the enquiry form deep in the site;
- skipping analytics and then not knowing where customers come from;
- forgetting the copy: without a strong offer even good design does not sell.
We run through this checklist at the prototype stage, when fixing a mistake is cheapest.
How the work runs
It starts with a consultation and technical brief, followed by a contract, prototype, design, development with integrations, testing and launch. After launch we help with hosting and changes. The price is calculated individually and free of charge, as it depends on site type, features and design complexity.
