Short answer: if people already search for what you sell (a dentist, a locksmith, a lawyer, an AC repair), start with Google Ads, because your ad shows up at the moment they are looking. If you sell something people want when they see it (food, clothes, beauty, events), start with Meta Ads on Facebook and Instagram. With a small budget, pick one, prove it works, then add the other.

What is the real difference between Google Ads and Meta Ads?
The difference is intent. On Google, the customer starts the conversation: they type "dentista en Caguas" or "plomero cerca de mí" and your ad answers a need that already exists. On Facebook and Instagram, nobody is searching for you. Meta shows your ad to people who match an audience while they scroll, so the ad has to create the interest.
That one difference decides most of the rest:
- Google Ads (Search): people with a problem today. Fewer people, but closer to buying. Your ad is mostly text, so the offer and the landing page matter more than the photo.
- Meta Ads: a much wider audience that was not looking for you. Lower cost to be seen, but the creative (photo, video, first line) does the selling.
Which one fits what you sell?
Use this quick test. Ask: "When someone needs my service, do they grab the phone and search?"
- Yes, they search (urgent or planned services): dentists, medical offices, lawyers, accountants, mechanics, AC repair, locksmiths, roofers, movers. Start on Google.
- No, they buy when they see it (visual or impulse products): restaurants and food trucks, boutiques, salons and barbers, bakeries, events, tours. Start on Meta.
- Both: gyms, real estate, home décor, private schools. Start where your best customers came from last year, and test the other later.
A restaurant in Santurce can fill a Friday with a good Instagram reel. A personal injury lawyer in Bayamón will rarely get a call from a reel, but will from someone who searched "abogado accidente de auto" at 10 PM.
How much budget do you need to start?
There is no magic number, but both platforms have rules that tell you how to think about it.
Google Ads works with an average daily budget. Per Google Ads Help, your campaign can spend up to twice the daily budget on a busy day, but in a billing period you are never charged more than 30.4 times the daily budget. So 10 dollars a day has a 304 dollar monthly ceiling. Google's own tip is to start small and check the account daily.
Meta Ads needs enough results to learn. Meta's help center explains that an ad set usually leaves the learning phase after about 50 results in the week after its last significant edit. If a lead costs you 15 dollars, that is roughly 750 dollars a week for one ad set to learn fully. With less, optimize for a cheaper result (messages or landing page views) instead of purchases. Meta may also spend up to 75% over your daily budget on some days, but no more than 7 times the daily budget in a week.
The practical rule for a small budget: one channel, one offer, one campaign, at least 30 days before you judge it.
Before you spend, decide what a customer is worth to you. If a new patient is worth 300 dollars over a year and one in three leads books, paying 40 dollars per lead still leaves room to grow. Do this math before the campaign starts, not after the first invoice arrives, so you know which number means stop and which means keep going.
How do you split a small budget between both?
Once your first channel brings steady leads, split it like this:
- Keep about 70% to 80% on the channel that already works. Do not starve what is bringing calls.
- Test the other channel with the rest for a month, with one clear offer.
- Use Meta for retargeting people who visited your website from Google but did not call. They already know you, so it is usually a cheap win.
- Judge by cost per lead or per sale, not clicks or likes.

What mistakes waste ad money in Puerto Rico?
- Ads in one language only. Many customers search in Spanish and scroll in both. Write the ad in the language your customer uses, and match the landing page.
- Sending ad traffic to a Facebook page with no prices or contact button. A simple page with your phone and WhatsApp converts better. See website or Google Business Profile first.
- Changing the Meta campaign every day. Each significant edit restarts learning.
- No tracking. If you cannot tell which ad brought a call, you cannot cut what does not work.
- Targeting all of Puerto Rico when you only serve one area. Set the location to where you actually work.
