Online Marketing “One-Woman-Show”

Passionate online marketer. 10+ years of experience. Lover of numbers.

Start-Ups, corporations, agencies… I’ve seen it all, but it’s not nearly enough. The art of learning and discovering new things drives me, and sharing my experience and knowledge is my passion.
I founded OnMaS with the main goal to support small and medium-sized businesses in online marketing. Whether it’s strategy, infrastructure or even implementation, my service is completely customized for each client.
The cornerstone is a good cooperation and a clear understanding of my clients’ products – only then can we create successful marketing strategies. I look forward to supporting you.

How I work

From the moment we start to work together until we accomplish your goals, you have full transparency in anything I do for you. There is always room to question, challenge or adapt things in order to achieve the best results that work for you.







Meet my long-term clients who I helped on the road to success.

She is open to try and test new approaches to bring your brand forward.

Barbara is, without doubt, the most experienced and knowledgeable online marketing manager I‘ve met in 12 years of my marketing career. I already know her for 10 years. She motivated me to start my blog (www.martynaschmeckt.com) and always supported creative thinking. Barbara helped me with all technical aspects, SEM questions and other marketing activities. Not many people are so efficient as Barbara! It‘s always a pleasure to work with such an inspiring professional. Her technical understanding combined with marketing expertise and hands-on mentality makes Barbara the best choice of online marketing advisor for any company. I strongly recommend Barbara to everyone who is looking for a great online marketing expert!
