Please describe your company and your position there.
The company focuses on selling car accessories. The offered products are mainly designed to increase the functionality and usability of vehicles during travel, as well as to protect and improve the appearance during their use.
For what projects/services did your company hire Sempai, and what were your goals?
- SEO audit - our company started cooperation by ordering SEO audit of a newly built store. The aim was to verify and analyze the store, whether it is properly made and prepared to function correctly according to current standards.
- Google Ads campaigns - the goal was to carry out activities increasing the recognition of our brand with a strong focus on increasing the reach and sales of the products offered.
How did you select this vendor and what were the deciding factors?
The company provides information about its services in a clear manner. Regular participation in international awards has been a great advantage attesting to the actual knowledge and effectiveness of the services offered.
Describe the scope of work in detail, including the project steps, key deliverables, and campaigns.
SEO audit:
- Analysis, verification of SEO in the online store.
- Preparation of a comprehensive report on the current status, construction of the store and applied solutions in terms of SEO. The report also contained information on which elements required improvement and how to make those changes. The whole service was provided in a clear and readable manner. I rate the quality of the service very high.
Google Ads campaigns:
- Configuration of the store with Google Ads advertising accounts
- Product feed verification
- Conducting advertising campaigns with set budget goals.
- Monthly reporting of advertising activities.
Google Ads campaigns are run professionally from the very beginning, taking care of the client's budget and meeting their expectations. At the beginning, Google Ads campaigns were run in Poland. Currently, Ads campaigns are also run in 10 European Union countries. All campaigns regardless of the country are conducted with great care.
Thanks to Sempai's actions, we effectively reach a large number of customers in accordance with the strategies agreed upon on an ongoing basis.
How many people from the vendor's team worked with you, and what were their positions?
Client Service Team Leader - 1 person SEM Specialist - 1 person
Can you share any measurable outcomes of the project or general feedback about the deliverables?
The overall results rating is very high. All services are performed professionally along with effective achievement of mutually agreed upon goals.
Describe their project management style, including communication tools and timeliness.
We are assigned an individual account manager who manages all projects for our company. The person assigned to the cooperation knows very well our expectations and goals, which we discuss and set on an ongoing basis. Availability and contact (phone and e-mail) are very good. All services are performed in accordance with the established deadlines.
What did you find most impressive or unique about this company?
The client does not have to be an expert in the field they are entrusting to Sempai. Excellent contact and communication ensures that the client is generally aware of what activities are being performed and understands the stages of a particular investment. All activities are reported in a client-friendly manner.
Are there any areas for improvement or something they could have done differently?
I don't see the need for it.

Please describe your company and your position there.
I am the founder and CEO of Cocolita.pl. We are one of the largest online drugstores on the Polish market.
For what projects/services did your company hire Sempai, and what were your goals?
We hired Sempai to support our company in the field of SEM and SEO because we did not have specialists in this field in the company.
How did you select Sempai and what were the deciding factors?
The agency was selected after analyzing the offers of many companies. We chose it because of good recommendations, a partnership approach to cooperation and good price conditions.
Describe the scope of work in detail, including the project steps, key deliverables, and campaigns.
As a relatively small store, we wanted to raise our position in Google's results and launch the first Google ads campaigns. After several months of cooperation, Sempai proved to be a reliable partner, which is why we increased our budgets and started cooperation in other channels, e.g. Facebook, TikTok and content marketing.
How many people from the Sempai team worked with you, and what were their positions?
We work with a group of specialists responsible for various areas, from marketing to SEO.
Can you share any measurable outcomes of the project or general feedback about the deliverables?
Our positions in the google search engine results increased in a relatively short period of time for most of the phrases that are important to us. Currently, over 400k sessions per month come from organic traffic.
ROI from advertising expenses is at a satisfactory level practically throughout the duration of our cooperation.
Describe their project management style, including communication tools and timeliness.
Once a quarter, we conduct workshops with SEMPAI to summarize the results so far and plan the next months. From our side we inform about new brands and categories that we will introduce to the offer and the agency suggests phrases for which they think it is worth positioning. At the end of each month, we receive a report on the result of their work.
We have designated KPIs for which the agency is counted.
What did you find most impressive or unique about this company?
Their cooperation and solutions have allowed us to stay ahead of the market. The possibility of contacting the guardian at any time. Sempai supported us as an expert during the DueDiligence process during the sale of the company's shares.
Are there any areas for improvement or something they could have done differently?
At this moment I don't have any ideas.
