7 Best SEO Agencies in Portugal (2026)

Its GEO page lays out a four-part method covering entity and knowledge graph optimisation, schema markup, content grounding and retrieval readiness, plus a baseline audit of current citation presence and ongoing share-of-voice reporting. Its case studies name real clients with numbers, including a documented link building campaign for the crypto exchange Bitvavo and a 20 percent visit increase with 642 leads for an enterprise client. Its Clutch profile shows 4.9 out of 5 from 10 reviews.

You want a technically detailed GEO method backed by named, checkable case studies rather than an AI visibility pitch.

• Names real clients with specific results rather than anonymised case studies
• GEO page describes a specific four-part technical method rather than generic AI visibility language
• Client roster includes recognisable brands such as Leroy Merlin and NordVPN

• Does not use the term AEO anywhere on its GEO page, so answer engine work is not a clearly distinct offering
• No pricing or minimum engagement is published, so quotes need a consultation call

It runs a dedicated GEO and AEO page listing concrete deliverables: llms.txt implementation, JSON-LD schema for FAQPage, HowTo, Article and LocalBusiness types, crawler configuration for GPTBot, ClaudeBot and PerplexityBot, and monthly citation monitoring across ChatGPT, Perplexity and Gemini. It is the only agency here that publishes an actual price for the work.

You want a technically specific GEO and AEO setup at a published price rather than a custom quote.

• Publishes an actual price, a 150 euro one-time setup package plus optional monitoring from 90 euros a month
• GEO and AEO get a dedicated page with named technical deliverables rather than one blended pitch
• Registered Portuguese company with its company number shown on the site

• A single-owner company spanning web development, chatbots, 3D printing and AI automation, so search is one of many offerings
• Case studies on its site are anonymised, so named client results cannot be checked before signing

Its AEO and GEO page breaks the work into five named steps: an AI presence audit across ChatGPT, Perplexity and Gemini, content optimisation for citation using schema and direct answers, trust signal building, continuous mention monitoring, and a content strategy targeting both assistants and Google. It is one of the few agencies here showing checkable large-brand clients on its own homepage.

You want AEO and GEO folded into a broader retainer with an agency that already serves enterprise accounts.

• Client logos include checkable large accounts across software, hardware and banking
• The AEO and GEO service is broken into five named steps rather than one pitch
• States more than ten years operating in Portuguese digital marketing

• No pricing, case study numbers or AI-specific client results are published, only the general logo wall
• No exact founding year is stated, only a rounded tenure claim

Its AI search page names both GEO and AEO explicitly and lists six deliverables: citation tracking, featured snippet optimisation, schema markup, voice search optimisation, AI-readiness content strategy and knowledge panel development. Its about page states more than 12 years in the Portuguese market and over 200 completed projects.

You want one team handling classic SEO plus GEO and AEO together, from a business with a stated founding date and a named founder.

• States an explicit founding year and names its founder, which most agencies in this market do not
• GEO and AEO are named and described with six concrete deliverables rather than bundled into one line
• Publishes a specific project count on its own about page

• No individual client names or AI visibility case study numbers are published, only aggregate claims
• Based in a small town rather than a major city, so in-person meetings may mean travel

It runs a standalone GEO page describing five steps: an audit of current brand visibility, GEO content strategy, technical work including schema markup, local GEO, and ongoing monitoring and reporting. Its stated track record of nearly twenty years is longer than most agencies in this market.

You want GEO added to an established generalist shop with a long operating history rather than an AI search specialist.

• States close to two decades in digital marketing, longer than most agencies here
• GEO page names five specific steps rather than describing the work in general terms
• Operates from a named, checkable business address plus a second office in Faro

• Does not mention AEO anywhere on its site, so answer engine work is not a distinct offering
• No client names, case studies or pricing are published for the GEO service

It runs a standalone page for AI discoverability describing semantic structure optimisation, contextual authority building and presence work across generative search and language models. Compared with others in this market its description leans conceptual rather than technical, so it is listed here with that caveat.

You want AI visibility bundled with brand and paid media from one Lisbon team, and are prepared to pin down deliverables before signing.

• Has a dedicated page for AI visibility rather than folding it into a general SEO pitch
• Bundles AI visibility with website, social and paid media under one Lisbon team
• Publishes a direct phone line and email rather than only a contact form

• The AI visibility page describes the work in conceptual terms rather than naming specific technical steps, the thinnest GEO evidence in this list
• No client names, case studies, founding year or pricing are published

It shows a real client logo wall on its own homepage naming recognisable Portuguese and international retail and travel brands. It states it is a specialist in SEO and language model services and offers strategies to appear in AI tools, but that is a homepage tagline rather than a service page with named deliverables, so it is not tagged for GEO or AEO here.

Deep SEO-only experience and a checkable roster of recognisable retail clients matter more to you than a built-out GEO programme.

• Client logo wall on its own homepage names recognisable retail brands
• States more than 12 years focused exclusively on SEO, a longer tenure than several others here
• Publishes a street address and direct email rather than only a contact form

• Its AI language is a homepage tagline rather than a service page with concrete deliverables, which is why it carries no GEO or AEO tag
• Its published case studies are anonymised, so the client logos cannot be matched to documented results
