SpartAds is my agency and is clearly identified as such here. The order in which the other companies appear carries no ranking of quality. The descriptions summarize the services presented on each company's own website, and it's up to you to confirm directly with each team their availability and fit with your project.
SpartAds: My Agency
At SpartAds we work on growing service businesses and ecommerce brands through marketing strategy, customer acquisition, and online advertising. If you're looking for help with Google Ads, Meta Ads, or online sales, you can present your business to the team and see whether there's a fit.

The SpartAds team.
We work the main paid traffic channels, mainly Meta Ads and Google Ads, and we adjust the buying journey to the reality of whoever is selling services or physical products. When the challenge is connecting traffic to closed sales, we look at the steps where contacts get lost, something I also cover in the article on how to build a lead funnel your sales team can actually work with.
For AI and automation we have SpartAds.ai. The conversation always starts with the specific process you want to improve, whether that's initial qualification of contacts, sales follow-up, or repetitive tasks that eat up your team's time. If you want to understand better where to start, I wrote about it in the article how to use AI in your business beyond chatbot questions.

Other Agencies in Porto and the Region
I've gathered here digital, creative, and communications agencies operating in the Greater Porto area, each offering different services. They're not all alike: compare what each one actually does against what you need, and note that some listed as "Porto" have offices in Gaia or Matosinhos instead.

How to Prepare Your Brief Before Contacting Suppliers
A well-prepared brief saves weeks of vague conversations and prevents you from receiving quotes that are disconnected from your actual financial or technical reality. Before writing to any agency, gather concrete numbers from your sales history and an honest picture of your team's real limitations.
Many companies contact agencies saying only that they need to sell more or gain visibility, which doesn't give anyone enough information to respond properly. Write down your current customer acquisition cost, if you know it, how many proposals your team can handle per month, and what internal resources exist to produce content or respond to inquiries. Imagine, as a hypothetical example, a service business that receives twenty inquiries a month but can only respond to half of them on time: that's far more useful information for an agency than simply saying "we want to grow." If you sell higher-value services, this topic is developed further in the article on how to convert more leads into clients in a service business.
Also include your company's technological starting point: what CRM you use, whether your tracking tags are installed and properly configured, and who is responsible for technical changes to the website. No agency can fix a traffic problem if the site takes too long to load or if customer inquiries sit forgotten in an inbox with no one handling them.
Criteria for Evaluating Agency Proposals
Evaluating a proposal means separating generic promises from concrete delivery and measurement processes. It's worth paying close attention to three things: who owns the access credentials, how the budget is broken down, and who will actually be working on your project day to day.
The first point, and perhaps the most important, is ownership of your digital assets. The ad account, the domain, analytics access, and any audiences created should always belong to your company, even if the agency handles setup and daily management. Keeping everything inside the agency's aggregated accounts creates an awkward dependency if the contract ends and you need to switch providers.
The second point is a clear separation between the cost of the service and the advertising spend itself. Ask for separate invoices for the agency's work and for payments to the platforms, such as Meta or Google. It's also worth looking at what margin remains after these costs, a topic I develop in more detail in the article growing an online business and what I learned about margin, team, and AI.
Finally, ask who your day-to-day contact will be. It's not uncommon for the initial sales contact to be made by experienced professionals, while execution afterward falls to other hands with less oversight. Ask who you'll have your follow-up meetings with, what the usual communication channel is, and how often you'll receive data on campaign performance.
AI and Automation in Agency Proposals
Including AI or automation in a proposal only makes sense if it speeds up an already identified process or improves a concrete result you can actually verify. Be wary of proposals that present the technology as a selling point without specifying what changes in practice for your business.
When a proposal includes automations, ask what tools are used and how human validation of the data is handled. A poorly configured automation could, hypothetically, send the same message twice to a customer or record incorrect data in your sales system, and that ends up costing more than it saves. The real gain should be visible in the time your team stops spending on repetitive tasks or in how quickly they respond to a new contact.
No tool replaces business decisions or guarantees better results on its own. When talking to agencies in Porto, keep your focus on what actually matters for your company: channels you can measure, a sales process with clear stages, and the certainty that access and data remain yours regardless of who manages the campaigns.
If you haven't written your brief yet, the practical next step is to gather the numbers I described above before scheduling your first conversation with any agency on this list.
