The same principles on every project, regardless of size
Here are a few examples from our work.
These are the experiences of directors and owners of companies we've built sites, applications, and SEO/AEO optimization for.
"We had a site, but nobody could find it on Google. Quantex carried out technical and content SEO optimization, and today clients find us directly through search, without paying for every click."
"Our old site was slow and hard to use on a phone, and most of our clients browse listings from their phone. Quantex built a new, fast site that clearly presents our listings and is easy to search."
"We didn't have an IT team, so we were worried about needing a custom web application. Quantex handled the entire build with clear explanations, and now we have an internal tool our team uses every day without a single call to a developer."
"We didn't even know something like AEO optimization existed until Quantex explained that customers increasingly ask ChatGPT and Perplexity instead of Google. Now those assistants recognize us as a source when someone asks about our industry."
"Patients used to find us only through word of mouth. After local SEO optimization and cleaning up our Google Business profile, we became visible for searches like 'dentist' in our part of town."
"We had a site, but it looked like it was from the last decade. Quantex redesigned it and carried out SEO optimization at the same time, so we got a modern look and a better search position in a single project."
"Our dispatchers used to build schedules by hand in Excel. Quantex built us a custom web application for route planning that connects with our existing systems and saves them several hours a day."
"Our students kept asking us the same questions about enrollment and schedules. Quantex structured the site's content so the answers are clear and easy to find, both for visitors and for AI search."
"We used to send clients Word reports by hand every Friday. Quantex built us a simple web application that generates the same reports automatically, with the same look our clients were used to seeing."
"I had no idea a small salon could have such a polished site. Quantex built a services showcase and price list that looks professional, and clients now message me directly through the site instead of calling."
"Our competitors kept outranking us in search even though we offered a better service. Quantex did an SEO analysis and made changes that gradually moved us to better positions for our industry's key searches."
"Our site was a static business card without a single photo of finished projects. Quantex built a new site with a project gallery and a clear call to action, and now inquiries come in directly through the contact form."
"Clients used to find us only through referrals. Since Quantex did our SEO and AEO optimization, we show up both in organic search and in AI assistant answers when someone looks for our type of service."
"As an architecture firm, our portfolio is everything. Quantex built us a site that presents our projects in a way that fits the profession, loads fast, and is easy to share with clients in meetings."
"Before, nobody could find us on Google Maps. Quantex fixed up our Google Business profile and local SEO, and now we're among the top results when someone in our area searches for dental services."
"We had hundreds of listings, and our old site couldn't display them well. Quantex built us a new site with filtered search, so buyers can find the property that suits them on their own."
SEO (Search Engine Optimization) is a set of technical and content changes on a site that help Google understand what the site is about and rank it higher for relevant searches. For a local business, that means being found by customers who are already searching for your services in your city, without paying for every click.
AEO (Answer Engine Optimization) is optimizing content so AI assistants like ChatGPT, Perplexity, and Google AI Overviews recognize, understand, and cite it as a source for their answers. While SEO targets the classic list of search results, AEO targets the direct answer a user gets from an AI system, without clicking through to the site. We achieve this with structured data, a clear FAQ structure, and content written as a direct answer to questions.
The first changes in indexing and technical site health are visible within the first few weeks. Movement in search rankings usually starts after 6 to 12 weeks, and steady growth continues as content and site authority build up. SEO is a process, not a one-time change.
It depends on the state of your existing site. If it's technically healthy but poorly positioned, SEO and AEO optimization is often enough. If the site is outdated, slow, or converts visitors into inquiries poorly, a redesign and rebuild deliver a better long-term result. The first conversation is exactly for this: to assess what's more cost-effective for your case.
A website primarily presents information and brand, it showcases services, builds trust, and generates inquiries. A web application has interactive functionality: user accounts, data processing, internal tools, or systems used by employees or clients. Many projects start as a website and gain application-like functionality over time.
A smaller business site typically takes 2 to 4 weeks from an agreed design to launch. Web applications depend on the scope of functionality, simpler projects take 4 to 8 weeks, more complex ones longer. We work iteratively, with regular progress reviews instead of you waiting for a final product.
Yes. After launch we offer monthly maintenance covering hosting, security updates, minor content changes, and ongoing tracking of SEO and AEO performance. The goal is for the site to stay fast, secure, and visible, not to be forgotten after launch.
Price depends on scope: number of pages, design complexity, whether custom functionality is needed, and whether SEO/AEO optimization is included alongside the build. After the first conversation you get a concrete quote with a clear price, no hidden costs.
No agency can honestly guarantee an exact position, because no third party controls the search algorithm. What we can guarantee is a technically healthy site, relevant content, and a consistent SEO/AEO strategy, the approach we applied for our client angelicphoto.rs, where we achieved the #1 position for all key services in Pančevo.
