At Comunicare, we know that the goal of digital advertising is not to generate impressions but to persuade potential buyers and increase brand recognition until you achieve your goals. Our work focuses on innovating with the maximum possible knowledge of each platform to help you achieve your objectives in the shortest possible time, while giving you a real vision of the project and setting achievable goals within specific deadlines. 

We never launch digital advertising campaigns without testing commercial arguments with big data and A/B Testing tools to identify the most effective commercial arguments and ensure that most of the budget is invested in the most effective ads. We update campaign data in real-time so that our control and reporting of campaigns is total. 

We constantly request feedback from our clients to ensure that the quality of the traffic we generate is ideal and that we reach audiences with the highest conversion potential. 

We meet monthly with the entire team involved in the projects, as well as the agency partners, to ensure that the strategy we follow is the most suitable and to contribute as much as possible to each project. 

We work across all channels and distribute your budget to ensure the maximum return on investment in each channel. Sometimes, we will recommend slowing down investment in some channels and increasing it in others in order to achieve the best results in the short, medium, and long term, designing realistic yet ambitious marketing plans. 

Our team consists of account managers and technicians from each of the areas we work in. In the case of social networks, we have technicians specialized in each platform to ensure the maximum "know-how" for each strategy we implement. 

We are responsible for disseminating more than just our own commercial arguments. We do smarter marketing with a more elaborate strategy designed to persuade more demanding potential clients who don't believe everything brands tell them. We combine our own content with third-party content within the advertising strategy to convince even the most demanding clients that we are their best option. 

SEO today is not based on tricks but on hard work and excellence.

We know the hundreds of factors that affect a website's ranking and we have a plan to optimize each and every one of them so that we don't have to doubt which are the most relevant.

We work with hour packs to demand the same from ourselves month after month, regardless of position, as there are always new keywords and the level of demand should never decrease.
