Four Dots
Four Dots is a Belgrade-founded digital marketing agency operating since 2013, with a team of 30 or more and further offices in Novi Sad, New York, Hong Kong and Sydney. It holds Google Premier Partner status and names enterprise clients including Coca-Cola, Philip Morris International and Orange on its own site.
It sells AI visibility optimisation as a named service built around its own monitoring platform, which it describes as tracking brand citations across ChatGPT, Gemini, Claude, Perplexity and Google AI Overviews in more than 195 countries. The service page lays out a three-part process covering an AI presence audit, content and entity optimisation, and ongoing monitoring.
You need enterprise-scale technical SEO plus ongoing measurement of how several assistants describe your brand, not a one-time audit.
- Runs its own AI visibility monitoring platform covering five assistants rather than relying on third-party tools
- Names enterprise clients directly on its site rather than showing anonymous logos
- Holds Google Premier Partner status
- No pricing is published anywhere on the site, so every service requires a contact form or call
- Operates from five offices across four continents, so a buyer wanting a Serbia-focused boutique may prefer a smaller shop
MaxDesign
MaxDesign is a Belgrade digital agency active since 2013 that describes itself as a senior engineering team working without outsourcing or subcontractors. It sells web development, technical SEO and AI search services as separate line items rather than one bundled package.
It publishes two separate service pages, one for GEO and one for AEO, each with its own four-stage method covering audit, entity and content architecture, schema implementation, and iteration against AI search signals. The GEO page names the assistants it tests against and the AEO page targets featured snippets and People Also Ask positions specifically, which is more granular than a single combined AI page.
You want GEO and AEO scoped as genuinely separate deliverables rather than bundled into one AI SEO line.
- Publishes distinct, detailed method pages for GEO and AEO rather than one blended service
- States a no-outsourcing, senior-team-only delivery model
- Names the specific assistants it tests GEO work against
- Does not disclose team headcount beyond describing itself as a senior team, so scale is unverified
- No pricing is published, with the site directing buyers to request a snapshot instead
Avokado
Avokado is a Belgrade-registered IT company that publishes its company registration number and states a team of 30 or more specialists across more than 250 completed projects. It names clients including a dairy group, a telecoms operator and a flooring manufacturer, and sells SEO, paid search, social advertising and web development alongside AI optimisation.
Its AI optimisation page describes six components covering technical foundation, content structure, authority building, ecommerce optimisation, data accuracy and continuous monitoring, targeting Google AI Overviews, ChatGPT and Gemini. It is the only agency in this market to publish an actual project budget range rather than requiring a call for a ballpark.
You want an established larger team with a disclosed budget range, and can work within its stated limit of one AI optimisation client a month.
- Publishes an actual project budget range for AI optimisation, unlike anyone else in this market
- States a team of 30 or more and over 250 completed projects, with named clients
- Registered as a company with a public registration number rather than operating under a trading name alone
- States it accepts only one AI optimisation client per month, which limits availability if you want to start immediately
- No founding year is stated, with only a 2016 copyright start implying its operating history
Envie
Envie is a Belgrade digital marketing agency that states it has existed since 2010, offering SEO, website development, Google Ads, social media management and copywriting. It sells answer engine optimisation as a distinct named service rather than folding it into general SEO.
Its AEO page lays out five concrete components covering an audit, AI query research, content restructuring, technical and semantic optimisation, and brand authority building, and names five target systems. It also sets expectations directly, stating initial results typically appear in 4 to 8 weeks and fuller visibility takes 3 to 6 months.
You specifically want content positioned to be quoted as a direct AI answer, backed by SEO work dating to 2010.
- Operating since 2010, a longer track record than most AI search entrants in this market
- Its AEO page names five specific target systems rather than speaking generically about AI search
- Publishes a stated results timeline rather than leaving expectations open
- No team headcount or named clients are published
- No pricing is disclosed for AEO or any other service
Advance Digital
Advance Digital is a Novi Beograd digital marketing agency with a publicly listed team of 10 across roles including leadership, account management, design, video, development and paid search. It sells integrated SEO, paid social and website development alongside a named GEO service.
Its GEO page sets out four components covering AI-friendly content structuring, entity and semantic optimisation, technical work including schema markup aimed at language models, and authority building, naming its specific targets. The site lists identifiable client logos including an insurer and a private equity firm rather than only testimonials.
You want a named multi-role in-house team and are comfortable with GEO scoped to Google's generative search and ChatGPT specifically.
- Publishes a 10-person team by role rather than an anonymous team claim
- Its GEO page includes concrete technical detail, including schema markup and answer formatting, not just a definition
- Lists identifiable client logos on its site
- No founding year is disclosed, and the homepage's own years-of-experience counter renders unpopulated
- GEO targeting is narrower than competitors here, naming only Google's generative search and ChatGPT rather than Gemini, Claude or Perplexity
How we ranked these agencies
- Depth of SEO experience, not general marketing
- Third-party review score on Clutch, GoodFirms or G2 where published
- Named services and a clear, public description of the offer
- Company longevity and team size
- Fit for enterprise versus small and mid-size brands
- Pricing transparency
- Evidence of real, named client work
Every agency listed is real and operating. Founding years, ratings and services come from the agency website or a third-party review platform, verified 2026-09-17. Where a figure is not published, the page says so rather than estimating.
Why work with a SEO agency in Serbia
The strongest agencies here were built as technical SEO shops between 2010 and 2013 and have layered AI visibility work onto that existing infrastructure, rather than launching as AI-only startups.
One Belgrade agency built its own AI monitoring platform, tracking brand citations across ChatGPT, Gemini, Claude, Perplexity and AI Overviews in more than 195 countries, instead of reselling a third-party tool. That is unusual for a market this size.
Serbia's software outsourcing economy means many web development shops add a search or AI optimisation line without real depth behind it. Check for a dedicated service page with stated deliverables rather than a navigation label or a single blog post.
Published pricing is rare. One agency states a project range in US dollars rather than euros or dinars, which is worth confirming directly before budgeting.
Only one of the five publishes a figure, a 3,000 to 20,000 US dollar project range for its AI optimisation service. The other four require a contact form or call before quoting anything.
