What it is
What a high-performance website is
A high-performance website loads fast, works well on mobile, is found on Google and leads the visitor to a clear action, such as requesting a quote, messaging on WhatsApp or buying. It is built around what Google calls Core Web Vitals (loading, interactivity and visual stability), has technical SEO from the first line of code and includes tracking so you can measure what each page delivers.
Corporate site
Authority and a solid digital presence. A site that conveys credibility, explains what you do and turns interest into contact.
Online store

OperationsProject types
Choose the right format for your goal
Each project has a role in the sales funnel. We recommend the format by your goal, not by what is trending.
SITE
Corporate site
The showcase and base of your digital presence. It presents the company, the services and the trust signals, and concentrates your contact channels.
SHOP
Online store
To sell products or services online: catalog, cart, checkout and after-sales integrated with your management system.
LP
Landing page
One page, one offer, one action. Ideal for ad campaigns, launches and capturing qualified contacts.
Many projects combine all three: the corporate site as a base, landing pages for campaigns and the store to sell.

Is your website costing you sales?

Performance
Speed is conversion: what we measure on every page
Google assesses page experience with three metrics, the Core Web Vitals. Slow sites lose visitors before they even see the offer, and that also weighs on rankings.
Visitor
→Loads fast
→Gets the offer
→Converts
→CRM
→Measures
LCP · Loading
Speed
Measures how long the main content takes to appear. We optimize images, fonts, caching and server so visitors see the page right away.
INP · Interactivity
Response
Measures how well the page responds to clicks and taps. We cut heavy scripts so the site doesn't freeze.
CLS · Stability
Visual
Measures whether elements jump around while the page loads. We reserve space for images and ads.
Continuous measurement
Data
We track the metrics after launch to fix regressions before they turn into lost leads.
Speed is not a technical detail: it is your brand's first impression and part of what Google considers in page experience.

FAQ
Questions about website development
How long does it take to build a website?
It depends on the type and scope: a landing page is much faster than an online store with integrations. After the briefing, we present a schedule with the steps and agreed dates.
What technology do you use?
We choose the platform by your goal and your team. WordPress with Elementor and WooCommerce serve most corporate sites and stores; projects with specific requirements may use other technologies. We explain the choice in the proposal.
Does the site come optimized for Google?
Yes. The technical SEO structure, such as titles, structured data, sitemap, URLs and speed, is part of development. To keep growing in search, content and authority work is done with our SEO service.
Will the site be mine?
We recommend, and agree in the contract, that the domain, hosting and analytics accounts stay in your company's name, so you have full control of what was built.
Do you integrate the site with the CRM and WhatsApp?
Yes. Forms can send leads straight to your CRM and email, and WhatsApp buttons come with a pre-filled message. We also connect n8n or Make automations when it makes sense.
Does the site comply with LGPD?
We apply good practices: HTTPS, a cookie notice when there is tracking, forms with consent and a privacy policy. Full compliance depends on the company's processes, and we can support that.
Do you look after the site once it is live?
Yes. We offer hosting, backup, updates, monitoring and continuous evolution so the site stays fast and secure.
Can I redo a site I already have?
Yes. We analyze the current site, keep what works, such as content and Google rankings, and handle redirects so you don't lose traffic in the migration.
