Rocket Digital, the second best SEM agency in 2021 according to the M4C ranking.


Marketing 4 eCommerce, the leading online portal in Spain specialized in e-commerce marketing, has been developing for some years the Ranking of the best SEM agencies in Spain, based on internal data that the platform itself requests to the different agencies.


SEM (Search Engine Marketing) agencies are really the Google Ads ecosystem, encompassing both advertising or SEA (Search Engine Advertising) and SEO (natural search engine optimization).


To arrive at this classification, the platform conducts an online survey of the most prominent companies in the sector, consulting the following data:

  • Total number of Google Ads clients.

  • Turnover managed in Google Ads during 2020.

  • Number of new Google Ads customers acquired during 2020.

  • Managed turnover in Google Ads of new clients 2020.

  • Average investment per client (own calculation).

  • The number of Google Ads optimizers.

  • The number of Google Ads optimizers with a degree in Google.


Based on these criteria, the following is assessed:

  • How many brands already trust the SEM agency.

  • How much trust they have in the market

  • Volume of business left in their hands

  • Average size of their clients

  • Size and skills of their team


In 2020, Rocket Digital (then RocketROI) occupied the first position in the ranking. This 2021, the digital consultancy defends its spot on the podium, dropping just one spot from last year and positioning itself in second place.


Being an agency specialized in SEM (among other areas in which they are also experts, such as UX/UI Design, Paid Media or CRO, among others), Rocket Digital has clients such as Allianz, Intersport, Exoticca and IDEA, among others.



This is how Rocket Digital distributes the investment in its SEM campaigns:

  • % of SEM investment in Search: 35%

  • % of SEM investment in Display: 15%

  • % of SEM investment % in Shopping: 40%

  • % of SEM investment in Video: 10%


The importance of companies and businesses that develop their activity in digital media to have an SEM agency that helps and advises them in the design, development, implementation and evaluation of their digital marketing strategy is crucial; since without the necessary capacity and knowledge it will be difficult to achieve the best results in their campaigns while obtaining the highest possible return on their investments.
