This directory lists 588 agencies in Spain, spread across 144 cities. 543 of them publish a direct contact (email or phone). The best-represented cities are Barcelona (133), Madrid (87), Málaga (45).
| Team size | Spain | What it means |
|---|---|---|
| 1-10 | 483 (82%) | One contact, often the founder. Responsive, limited capacity. |
| 11-50 | 54 (9%) | Specialists per discipline. The most common trade-off. |
| 51-200 | 1 (0%) | Several teams, formal process, higher budgets. |
| 200+ | 1 (0%) | International structure, enterprise accounts. |
Across the 588 agencies in this country: SEO (98%), Web Design (70%), Social Media (48%), Web Development (41%), SEA/PPC (40%), Content Marketing (31%). SEO leads with 575 agencies.
Stated engagement floors in Spain range from $1,000+ to $100,000+. The most common is $1,000+ (126 agencies). That figure is an entry floor, not a price: it says what size of engagement the agency will take on, which stays the fastest filter for ruling out the ones that do not match your scale.
The 588 agencies on this page are ordered by how complete their listing is, not by payment: nobody buys a position here. The information comes from each agency's own website, checked as live. An agency can claim its listing to correct or complete it.
Should you pick an agency based in Spain? Proximity matters most for local SEO and the language your content is written in. Here, Spanish and English are the most declared working languages. For an international site, where the agency sits matters less than its experience in your market.
Small or large agency? 82% of agencies here have fewer than ten people, against 2 above fifty. A small team means direct access to the people doing the work; a large one absorbs heavier programmes without depending on one person.
What to check before signing? Ask for measured results on a site comparable to yours, who actually does the work, and what happens when the contract ends: deliverables and access must stay yours. An agency that will not show its method is selling a black box.
