So I have a spanish keyword that gets 60,000 exact global monthly searches The main country searches are: Brazil 18,000 Spain 15,000 Mexico 7,000 Portugal 4,500 Columbia 3,000 The .com is taken (undeveloped) but everything else is available. Which tld would you suggest? It won't be an e-commerce site.
Go for .net or .org if you want to target all of these countries. Also get the country specific extensions (ccTLD) and redirect them to your main site.
