Should I use one Spanish keyword list for every storefront, or a different one per country?

Start from one candidate list of concepts, then score the actual local words for each storefront separately. Spain and Mexico often share vocabulary; Argentina, Chile, and Colombia frequently don't. Scoring the wrong local word returns a difficulty number for a term nobody there searches.

Is Spain or Mexico a better first storefront for Spanish-language ASO?

Mexico has the larger population and a growing app market; Spain has more mature, entrenched competition in most categories. Score both — the better starting point depends on which vocabulary your app's category actually uses in each.

Castilian Spanish and Latin American Spanish diverge in real, searchable ways

Vocabulary differs on ordinary words that show up in app names and subtitles: a phone in Spain is often 'móvil', in Mexico 'celular'. A computer app might index for 'ordenador' in Spain and 'computadora' across most of Latin America. Neither is more correct; they're what users in each market actually type.

Argentina's voseo (using 'vos' rather than 'tú') affects imperative phrasing in subtitles and promotional text more than it affects single-word keywords, but it's a real register mismatch if you write instructional copy directly from a Spain-focused translation.

The eight storefronts above don't move in lockstep on difficulty. A term entrenched by established apps in Spain and Mexico is routinely open in Peru, Chile, or Guatemala, where fewer apps have optimized for the same vocabulary yet.

A workable Spanish-market research order

Score your core candidate list against Spain and Mexico first — the two largest Spanish-language storefronts by app competition — to establish a baseline vocabulary and difficulty range.

Re-score the same concepts, not the same words, against Argentina, Colombia, Chile, and Peru. Where local vocabulary differs, add the local term as its own candidate rather than assuming the Spain/Mexico word carries over.

Treat the smaller Central American and Caribbean storefronts (Guatemala, Dominican Republic, and similar) as low-difficulty opportunities once the vocabulary is confirmed relevant — competition there is often a fraction of Spain's for an identical concept.

What a straight translation misses

'Móvil' (Spain) vs. 'celular' (most of Latin America) for phone-related apps.
'Ordenador' (Spain) vs. 'computadora' (Latin America) for desktop/computer-related terms.
Voseo conjugation in Argentina and parts of Central America changes verb forms in instructional copy, not single keywords.
Formal usted-based phrasing reads as more natural in professional/business-tool subtitles across most Latin American markets than the informal tú forms common in Spain.
