Short answer
What does a custom web development project include?
Custom web development is the design and building of a website, store or application made for each client’s business, with no recycled templates. At TheNocGroup it includes UX/UI design, development, technical SEO, measurement, launch and optional maintenance. We work from Núñez, Buenos Aires, with businesses across Argentina.
Being online is not the same as selling online
Move the handle and compare a template website with a site built to convert.
Template websiteA generic message that could belong to any company.
Custom websiteA clear message on the first screen: what you do and who it’s for.
Template websiteToo many buttons and menus compete for attention.
Custom websiteA direct path to getting in touch, on every screen.
Template websiteHeavy and slow on a phone.
Custom websiteBuilt mobile-first and measured with Core Web Vitals.
Template websiteNo structure for Google or AI assistants.
Custom websiteStructure and data built so Google and AI understand you.
What we build
Every project starts from a business goal, not from a template.

For selling without middlemen

Catalog, payments and shipping in a fast store that’s easy to manage.
For organizing processes

WordPress or custom code: which fits you?
It’s just two steps: answer step 1, then step 2, and on the right we show the path we usually recommend. The final decision is made together in the consultation.
Your path
Answer both steps and the path we usually recommend will appear here.
You edit it
Editable WordPress site
Ideal if you want to change text and images or publish news on your own. We build it custom, with no recycled templates, with security and speed carefully handled.
Maximum speed
Custom-coded site
Ideal for sites that rarely change and need maximum speed and full control of the design. It’s published on Cloudflare’s global network.
Does more than display
Custom application
Ideal if your website needs to do more than display: dashboards, user accounts, quoting tools, bookings or connections to other systems.

What every project includes
A website that works is far more than a nice design. These are the layers we take care of in every project.
Mobile-first and true to your brand, so it’s understood quickly and leads to an inquiry.
A fast, tidy, easy-to-maintain site, with forms that work and reach your inbox.
Structure, copy and data built so Google and AI assistants understand your company.
SSL certificate, Cloudflare protection and forms with spam verification.
Search Console and Google Analytics 4 set up so you know where every inquiry comes from.
Updates, backups and support, on a monthly plan if you want one.
The three numbers Google looks at on your site
They’re called Core Web Vitals and measure how fast your site loads, how fast it responds and how stable it looks. We measure them before and after launch.
LCPLoading
or less2.5 s
How long it takes for the main content of the page to appear.
INPResponsiveness
or less200 ms
How long the page takes to react to a tap or a click.
CLSStability
or less0.1
How much elements move around while the page loads.
“Good” values published by Google, measured at the 75th percentile of real visits. We check them with PageSpeed Insights and the Core Web Vitals report in Search Console.
One project, five workstreams in parallel
We don’t wait for the design to be finished before thinking about rankings, or for launch before measuring. This is how the stages overlap.
Strategy and goals

UX/UI design
Deliverable: Desktop and mobile mockups for you to approve.

Frequently asked questions about web development
What people ask us most before getting started.
How much does a custom website cost?
It depends on the type of project, the number of pages and the features it needs. A corporate site, a store and an application have very different scopes. In the first consultation, which is free, we define the scope and send you a proposal with scope, timeline and budget.
How long does it take to build a website?
It depends on the scope: a landing page or corporate site takes less time than a store or an application. Before we start we give you the timeline in writing and follow it stage by stage, with your approvals.
Do you work with businesses in Núñez and the north zone?
Yes. Our office is at Vilela 2218, Núñez, Buenos Aires, and we work with companies in Núñez, Belgrano, Saavedra, Vicente López and the whole north zone. We also serve clients across the country remotely.
What’s the difference between web development and web design?
Web design defines how the site looks and how it’s navigated: identity, information order and user experience. Web development builds it so it works: speed, forms, security and connections to other systems. In every project they work together.
Should I choose WordPress or a custom-coded site?
WordPress fits if you want to edit content on your own. Custom code fits if you prioritize maximum speed or need very specific features. Both are built custom, with no recycled templates, and in the consultation we see which one suits your case best.
Is SEO included in the website?
Yes. Every site launches with the structure, titles, structured data, speed and measurement it needs to rank. The full audit and content strategy are a separate service: SEO, AEO and GEO.
Can I redesign my website without losing my rankings?
Yes. Before publishing the new site we take inventory of your pages and the searches you already appear for on Google. We keep the addresses that work and redirect the rest, so you don’t lose what you’ve already earned.
Do you offer support and maintenance after launch?
Yes. You can sign up for maintenance and support on a monthly plan: updates, backups and help if something fails. You can also add IT support for your company.
Do you build custom web applications?
Yes. We build dashboards, client portals, quoting tools, booking systems and applications that connect to your data and to other tools, to organize processes you currently do by hand.
How can I pay for the service?
You can pay by credit card, bank transfer or bank deposit. We agree on the details in the proposal.
