Web Design Agency in Istanbul

Short answer: Bilcod is a web design agency based in Kadıköy, Istanbul, since 2015. Our team has been building websites for over 20 years and has delivered more than 476 projects. We hand-code corporate websites, e-commerce sites, multilingual sites for exporters and custom web applications without off-the-shelf themes, on a fast, search-ready stack. We meet clients in Istanbul at our Kadıköy office and work with clients elsewhere in Turkey and abroad through online meetings.

On this page we explain what we do as a web design agency in Istanbul, what a web design agency actually does, what to look for when you choose one, how our process works and what drives the cost.

What Does a Web Design Agency Do?

A web design agency plans, designs, builds and launches a company's website, and maintains it after launch. "Web design agency" and "web design company" are used interchangeably. The real difference between providers is how much of the work they take on under one roof.

A website that brings in customers needs more than good looks. A sound web design project covers all of the following together:

• Strategy and information architecture: which pages the site needs and how a visitor reaches the quote form.
• User experience and visual design: an interface that matches your brand and works comfortably on a phone.
• Software: a fast, secure site that your team can update easily.
• Content and search foundations: heading structure, structured data, a sitemap and pages search engines understand correctly.
• Legal compliance: privacy notices, cookie consent and, for online shops, the required company details and sales terms.
• Launch and maintenance: hosting, security updates, backups and small changes.

When this work is split across different people, the usual problem is coordination: the designer draws one thing, the developer builds another and the SEO specialist finds the gaps after launch. At Bilcod, design, development and search work run in one team on one schedule.

What We Build as a Web Design Agency in Istanbul

If you are not sure which type of website you need, this table is a good starting point:

In redesign projects our first concern is keeping existing search traffic. We list the old URLs, connect each one to its new address with a permanent redirect and monitor errors in Search Console after launch. We used the same method when we rebuilt our own site, bilcod.com.

How to Choose a Web Design Agency: 7 Criteria

A search for web design companies returns dozens of options. These seven criteria show what to compare when you review proposals. You can apply them to us as well.

1. Live references. Open the agency's sites on your phone. Do they load quickly, does the contact form work? Ask for an example close to your industry.
2. Ownership. Who will own the domain, the hosting account, the source code and the admin panel? The contract should state that they belong to your company.
3. Search foundations. Are server-rendered pages, heading hierarchy, structured data and a sitemap part of the delivery, or sold separately?
4. Speed measurement. Does the agency set targets for Google's Core Web Vitals and give you a measurement report at handover?
5. Content management. Will you be able to add pages, images and blog posts without technical knowledge?
6. Legal compliance. Are privacy notices, a separate consent box, cookie consent and, for online shops, company details and sales terms included?
7. Process and aftercare. Will you have one point of contact and see interim demos? Are the scope and duration of maintenance written down?

Agency, Freelancer or Website Builder?

Each option is right in some situations. The choice depends on the role the website plays in your business and on your growth plans.

Our Web Design Process: 7 Steps to Launch

1. Discovery and strategy. We learn about your business, target customers, competitors and the results you expect from the site, and map out the pages together.
2. Information architecture and wireframes. We sketch each page and show you how a visitor will reach the quote form or the phone number.
3. Visual design. We design typography, colours and components that match your brand, for mobile and desktop at the same time.
4. Development. We build the approved design, the admin panel and the integrations you need.
5. Content, search and legal texts. We add titles and descriptions, structured data, the sitemap, privacy and cookie texts.
6. Testing. We test on different devices and browsers, measure speed and check forms and notifications.
7. Launch and maintenance. We put the site live, set up Search Console and analytics, and move on to maintenance.

We show you a live interim version every two weeks, so you never wait until the end to see the site. A corporate website usually takes 3-5 weeks; a multilingual or larger corporate site takes 6-10 weeks.

What Every Site Includes

• Mobile-first design: pages are designed for the phone screen first, then adapted to larger screens.
• Server-rendered pages: search engines see the content without extra processing.
• Structured data: schema markup for your business, services, FAQs and breadcrumbs.
• Speed targets: we write Core Web Vitals targets into the contract and share the measurements at handover.
• Admin panel: no technical knowledge needed to add pages, images or blog posts.
• Privacy-compliant forms and cookie consent: a link to the privacy notice, a separate consent box where required and consent for non-essential cookies.
• Accessibility principles: sufficient colour contrast, keyboard navigation, form labels and alternative text for images.
• Multilingual setup: language versions of your pages with the correct language tags, when you need them.

If you sell online to consumers in the European Union, the European Accessibility Act, in force since 28 June 2025, may apply to you. In that case we assess the accessibility requirements together at the start of the project.

Which Technologies Do We Use?

We build our sites with Next.js, React and TypeScript instead of ready-made themes, and use PostgreSQL where a database is needed. This gives us three things: pages that render quickly on the server, no security holes from unnecessary plugins, and a site that can grow with your business.

Our own site, bilcod.com, runs on the same stack, so we use what we recommend every day. We use AI-assisted coding tools as helpers during development; every design decision and every line of code is reviewed by our team.

Custom Code or a Ready-Made Theme?

A site built on a ready-made theme starts faster and costs less upfront. A custom-coded site brings fewer surprises in the long run. The difference shows in the role the site plays in your business:

We recommend custom code for companies whose website is a customer and enquiry channel. For those who want to go live quickly on a fixed budget, our Quick Website package strikes the balance.

Ready for Search Engines and AI Search

A website should be ready for search engines on the day it launches. That is why we build search foundations into the design instead of adding them later: a correct heading hierarchy, one clear title per page, structured data, an automatic sitemap, language tags and fast pages.

People now ask questions in AI-powered search tools as well as on Google. To help these tools cite your content, we structure headings as questions and give clear answers. We explain this in our article What is GEO? If you want ongoing ranking work after launch, see our SEO service.

Where We Work in Istanbul

Our office is in Kadıköy, on the Asian side of Istanbul. We can meet clients from both sides of the city at our office or at their premises when needed. District pages: web design in Kadıköy, web design in Üsküdar and web design agency in Ataşehir.

What to Prepare Before You Commission a Website

The biggest cause of delays is content and access details arriving late. Preparing these before the first meeting speeds things up:

1. Brand files: a vector version of your logo, brand colours and, if you have one, a brand guide.
2. Domain access: where the domain is registered, in whose name, and access to its control panel.
3. Current site data: analytics and Search Console access, if you have a site, to see which pages get traffic.
4. Services and products: the services you want to highlight, each with a short description.
5. Images: photos of your office, team, production and products. Real photos build more trust than stock images.
6. Reference permissions: written permission from clients whose name or logo will appear on the site.
7. Examples you like: two or three sites you like and dislike, with your reasons.

What Determines the Cost of Web Design?

The scope of the project matters more than the number of pages. The main items that affect a quote are:

• The number of pages and templates, and the size of the product or service catalogue
• Whether you provide the texts and images, or we produce them
• The number of languages
• Integrations such as quote forms, booking, payments or a CRM
• E-commerce, user accounts or a custom admin panel
• The scope of maintenance and content support after launch

For small businesses that want to go live quickly, we offer a fixed-price Quick Website package. For other projects, we prepare an itemised written quote after hearing your needs, and we list items such as advertising budget, domain and hosting separately from the design fee.

After Launch: Maintenance and Support

A website is not finished on launch day. Our maintenance covers:

• Security updates and regular backups
• Regular checks of forms, email notifications and integrations
• Speed and error monitoring, and follow-up on Search Console warnings
• Tracking domain and SSL certificate renewal dates
• Small text, image and page changes

We set the scope and duration of maintenance in writing in the contract; larger work such as new pages or features is planned separately.

Frequently Asked Questions

Is there a difference between a web design agency and a web design company?

In everyday use the two terms mean the same thing. In practice the difference is scope: some providers only design and code, while others also handle strategy, content, search work and maintenance. When you request a quote, asking which tasks are included, item by item, tells you more than the name.

How long does it take to build a website?

A single campaign page usually takes 1-2 weeks, a corporate website 3-5 weeks and a multilingual or larger corporate site 6-10 weeks. The biggest factor is whether texts and images are ready. We share the timeline in writing after the discovery meeting.

Who owns the domain and the website?

The domain, hosting account, source code and admin panel are registered to your company, and we put this in the contract. If you ever want to work with another team, your site and your data go with you.

Do you use ready-made themes?

No. We design each site around your brand and build it with Next.js and TypeScript. This keeps the site fast, reduces the security risks that come with unnecessary plugins and lets the site grow as your needs change.

Can I update my site myself?

Yes. Every site we deliver has an admin panel that requires no technical knowledge, so you can add and edit page texts, images and blog posts yourself. After launch we show your team how to use it.

Do you work with clients outside Istanbul or abroad?

Yes. We meet clients in Istanbul at our Kadıköy office and run projects with clients elsewhere in Turkey and abroad through online meetings. In both cases we share interim versions through a live link.

Is SEO included in web design?

Technical search foundations are part of every project: heading structure, structured data, a sitemap, speed targets and server-rendered pages. Ongoing content production, competitor analysis and ranking tracking after launch are a separate service under our SEO service.

Will I lose my Google rankings when I redesign my site?

Not if the migration is planned properly. We list the old URLs, connect each one to its new address with a permanent redirect and carry titles and descriptions over to the new structure. In the weeks after launch we monitor indexing in Search Console and fix any errors. Short-term fluctuation is possible; migrations without a URL plan can cause lasting traffic loss.
