Our qualifications

BVDW SEO Certificate

In order to receive this certificate, it is mandatory to sign a voluntary commitment which declares a serious and transparent way of working. Afterwards, case studies (including URL and description of the optimizations) must be submitted, which are anonymized (and therefore do not allow any conclusions to be drawn about the agency) and are checked by the SEO expert advisory board. In addition, five other customers must be named for an independent customer survey, specialist articles and lectures must be verified and a certificate of the annual SEO fee turnover must be submitted.

BVDW SEA Certificate

The basic prerequisite for the SEA quality certificate is the signing of the self-commitment for a transparent and serious way of working. In order to obtain the certificate, 10% of the company’s commitment to the market (lectures and technical articles), 20% of the experience in the field of SEA and 30% of the customer satisfaction of the 5 companies surveyed. The largest share, accounting for 40% of the overall score, is attributed to the working method, which is evaluated by an independent panel of experts.

Ryte Expert

We have been recognized for our expertise in dealing with the online software RYTE (formerly OnPage.org), which is used, among other things, to optimize texts and all OnPage factors.

Certified Agency – Sistrix Toolbox

Search Engine Optimization is complex and can actually only be carried out on the basis of comprehensive data by professional tool providers. We have received our SISTRIX agency certification through appropriate training and experience in using the market-leading tool in German-speaking countries. In addition, we also offer our customers (if required) access to this data and thus make reporting transparent.

Google Partner

Effective Search Engine Advertising is one of our strengths! As a Google Partner Agency you are recognized by Google for managing a certain budget and looking after it with a high level of performance for companies. Furthermore, our employees regularly attend Google training courses in order to continuously expand their specialist knowledge in the form of certifications – also helpful for maintaining the Google Partner Seal.

BVDW member

As a member of the Federal Association of the Digital Economy (BVDW, short for Bundesverband Digitale Wirtschaft), we are part of an expert network that contributes to promoting the image of the digital industry. In addition, we always receive the necessary information on legal issues such as the new GDPR 2018 at an early stage.
