The SEO market has more pricing confusion than any other digital service. Quotes range from €200/month to €15,000/month for services that sound identical on paper. In 2026, a new layer makes the confusion worse: agencies now bundle SEO with AEO (Answer Engine Optimization) and GEO (Generative Engine Optimization) without explaining why the price doubles.
This guide breaks down real SEO prices in Spain and LATAM, what each tier actually includes, how AI-search optimization changes the math, and the seven deliverables any serious agency must offer. The goal: you walk into your next agency call knowing exactly what a fair quote looks like.
SEO price ranges in Spain and LATAM (2026)
Based on analysis of 120+ agency websites and direct quotes from B2B buyers in Spain, Mexico, Colombia, Chile, and Argentina, these are the real ranges in April 2026:
Two honest warnings:
- Under €600/month, you get a spreadsheet, not a strategy. Real keyword research, technical fixes, content production, and link building cannot happen in that budget.
- Over €3,000/month for a B2B SMB usually means you are paying for agency overhead, not more results. The €1,000-€2,500 range delivers the best value.
Monthly retainer vs per-project pricing
90% of B2B SEO is billed as a monthly retainer. Projects are rare and usually tactical: a technical audit, a migration, a site relaunch.
Retainer makes sense when: you need continuous content production, link building, monthly reporting, and strategy adjustment. This is almost every B2B company.
Project-based pricing makes sense when: you have a specific one-off problem like a Google penalty, a migration, or a technical audit. Expect €1,500 to €8,000 per project depending on scope.
The cost of SEO for AI search engines: what no one is telling you
In 2026, AI search is no longer optional. ChatGPT has 800M weekly users. Perplexity is the fastest-growing search tool among B2B decision-makers. Google AI Overviews appears in 16%+ of searches. Your SEO budget now has to cover three disciplines:
AEO (Answer Engine Optimization) pricing
AEO is the optimization for featured snippets and direct answers on Google. Implementation cost: between €300 and €800/month on top of classic SEO. Most serious agencies include it as part of their standard service, not as an add-on.
GEO (Generative Engine Optimization) pricing
GEO is the optimization to be cited by ChatGPT, Perplexity, Gemini, Claude, and Copilot. Implementation cost: between €500 and €1,500/month depending on the number of models tracked and the competitive intensity of your category. For a deeper breakdown, see our GEO agency pricing guide.
Why AI Search Optimization costs more than classic SEO
- More models to track: not just Google, but 4-6 AI engines, each with different signals.
- Specialized content: citable answers, structured FAQs, schema.org implementation.
- External authority work: G2, Trustpilot, Reddit, industry media mentions.
- Monthly Share of Answer measurement across each AI model.
Classic SEO vs AI Search Optimization: price comparison
The 7 deliverables that must be in any serious monthly SEO fee
- Monthly technical audit: crawl errors, Core Web Vitals, indexing issues.
- Keyword research and strategy: real keywords with volume, not guesses.
- Content production: minimum 2 articles/month or the content is not working.
- Link building: between 3 and 10 quality backlinks/month.
- On-page optimization: title tags, meta descriptions, schema markup.
- Monthly reporting: rankings, traffic, conversions, AI citations.
- Monthly strategy call: 60-90 minutes to review, adjust, plan.
If a proposal does not include these 7, the quote is incomplete — regardless of price.
Services agencies charge extra for (and how to negotiate them)
- Initial technical audit: €500-€2,500. Many agencies include it in the first month.
- Website migration: €2,000-€8,000. Separate project pricing is standard.
- Penalty recovery: €3,000-€10,000. Highly specialized work.
- International SEO setup: €1,500-€5,000 per market. Multi-country adds complexity.
- Premium link building campaigns: €500-€2,000/month extra. Negotiable if committed quarterly.
Red flags: when an SEO quote is suspiciously cheap
- Under €400/month for 'professional SEO' in competitive verticals.
- 'Unlimited keywords' promised — impossible to deliver, not a real metric.
- 12-month mandatory contracts with no exit clause.
- No mention of AI, AEO, or GEO in 2026.
- No reporting access or shared dashboard.
- Agency does not rank for its own keywords.
How to calculate your minimum viable SEO budget
Simple formula: (monthly customer acquisition cost via paid) × (target organic traffic share) = minimum SEO investment.
Example: B2B SaaS with 50 employees
- Current paid CAC: €250 per demo
- Target: 20 organic demos/month within 12 months
- Minimum monthly investment: €1,100-€1,800 for 12 months
- Expected break-even: month 8-10
- ROI by month 14: 3-5x depending on close rate
This is the exact math behind Solumize's €1,100/month AI Search Optimization plan.
Before you sign: audit your current visibility
Any agency that wants to quote you without first understanding where you stand is guessing. Before paying for SEO, run a visibility audit to know your baseline in Google, ChatGPT, Perplexity, and Gemini. It takes 30 minutes and costs nothing. Our step-by-step GEO audit guide walks you through the exact method.
