A domain is the address customers will type, say out loud, and remember for years, which makes it a business decision, not just a technical checkbox during setup. A .mx domain typically costs $200-$400 MXN per year and a .com runs $250-$450 MXN, registering both together to protect the brand costs under $1,000 MXN a year combined, cheap compared to the cost of a competitor grabbing the other one later.
What makes a good domain
Short (ideally under 15 characters), easy to spell out loud over the phone, and free of hyphens or numbers that force an explanation every time someone shares it. If a customer has to spell it letter by letter, or clarify "with a hyphen" every time, it's already working against the business every single time it gets shared.
.mx, .com, or both
A .com signals broader, sometimes international reach, while a .mx signals a specifically Mexican business, which can build trust with a local audience. Pricing runs similarly, roughly $200-$400 MXN per year for .mx and $250-$450 MXN for .com depending on the registrar. When budget allows, registering both (under $1,000 MXN a year combined) and pointing one to the other protects the brand from a competitor grabbing the other extension later, a much cheaper problem to prevent than to fix.
What to avoid
Avoid domains that only make sense with an explanation, that are hard to say out loud without spelling them, or that depend on a trendy extension (.io, .co, .biz) that might not exist or be trusted in a few years the way .com and .mx reliably will. A domain chosen for being clever today can become a liability once nobody remembers the joke, or once the novelty extension starts looking dated instead of fresh.
What if the ideal domain is already taken
Adding a relevant, short word (the city, the core service, e.g. tunegocio-ensenada.com instead of tunegocio2024.com) usually works better than adding a random number or an unrelated word just to make it available. Buying an already-registered but unused domain from its owner is also an option, prices vary widely (anywhere from a few hundred to several thousand pesos) but it's worth pricing out before settling for a weaker alternative.
Frequently asked questions
It depends on the business. A .mx reinforces that the business is local Mexican, while a .com conveys broader reach. Both cost similarly (between $200 and $450 MXN per year), so if budget allows, registering both is the safest option.
Yes, but it means losing accumulated SEO authority and confusing customers who already know the old domain. It's far cheaper to choose well from the start (under $1,000 MXN a year for both extensions) than to migrate later.
It can help a little, but it's not as important as the domain being short, easy to say, and matching the business's actual name.
Add a short, relevant word, like the city or main service, instead of a random number. You can also try buying the domain from its current owner, with prices ranging from a few hundred to several thousand pesos.
