FAQ
What is the minimum recommended investment for Google Ads?
For most niches, an initial media budget of R$1.500 to R$3.000 per month allows for sufficient data collection for optimization. Highly competitive niches (law, healthcare, real estate) require more. The important thing is to start with a budget that allows for learning without compromising cash flow.
How long does it take for campaigns to generate results?
Well-structured campaigns generate initial leads within 48-72 hours. The optimization phase lasts 30 to 60 days, during which the algorithm learns which keywords, times, and audiences convert best. From the second month onwards, the cost per lead tends to decrease consistently.
What is ROAS and how do I know if my campaign is performing well?
ROAS (Return on Ad Spend) is the revenue generated divided by the amount invested in ads. A ROAS of 4x means R$4 in revenue for every R$1 invested. A healthy ROAS varies by niche, but in general, any result above 3x is considered positive for e-commerce.
What is the difference between Google Ads and Meta Ads (Facebook/Instagram)?
Google Ads captures existing demand — people who are already searching. Meta Ads creates demand — it interrupts users who weren't looking. In general, Google Ads converts better for products/services with high purchase intent, while Meta is ideal for awareness and the top of the funnel.
My ad is showing up but I'm not getting any clicks. What could be the problem?
Generally, the problem stems from: unattractive ad copy, an offer lacking a clear differentiator, a lack of ad extensions, a historically low CTR affecting Ad Rank, or overly broad targeting reaching an unqualified audience. An audit identifies the exact bottleneck.
