Our Test Methods

Launched as a two-person business in 2013, we today employ more than 70 freelancers and permanent staff to ensure the highest quality of information.

Reviewinstitute.org is an independent consumer portal with the aim of simplifying the purchasing decision for consumers through clear comparison tables and providing interested parties with expert and objective support during the purchasing process.

Our goal is to ensure that every website visitor finds exactly the product that best suits his personal ideas and needs. And it is fast, uncomplicated and simple.


Product comparisons, consumer tests and laboratory analyses

By combining different approaches, we have been creating reliable added value for our readers for years.

  • Product comparisons involving thousands of reviews ensure that our results also take the opinion of the market into account.
  • Consumer tests by our experienced product testers help to clarify specific questions.


Editorial workflow

This is how our product grades and rankings are created.

Step 1: Topic selection

  • Public Discourse – Which product categories are currently being publicly discussed? Are there currently more recalls from manufacturers in certain segments? Are there currently critical voices in certain product segments regarding possible pollution, inadequate processing or the like?
  • Competition analysis – about what do competitive websites write?
  • Data-driven needs analysis for search volumes of specific topics using tools such as Google Keyword Planner (Google Adwords) and searchmetrics
  • The result of this topic identification process is a pool of 50 – 100 product topics, which provides the basis for the subsequent work steps

Step 2: Market analysis

  • Where are the products in the individual categories from step 1 traded on the Internet? Which shops and trading platforms are known?
  • Which brands/manufacturers/dealers are relevant in the respective product categories?
  • Which specific products are offered online?

Step 3: Research

3.1 Ratings

  • Where can I find reviews on the individual products on the web?
  • Noting down these shops/portals and collecting ratings for each product
  • Formulating a relative valuation of averages
  • Identifying the typical weaknesses and strengths of the products according to the online evaluations and classifications based on their frequency

3.2 Product features

  • Preliminary considerations – Which product data make sense to be recorded and compared later on?
  • The product characteristics mentioned by the manufacturers/dealers are researched and noted in the online shops
  • If important data is missing due to insufficient product description, the respective manufacturers will be contacted by e-mail and telephone

Step 4: Product selection

  • Based on the information acquired in step 3, it is defined which products are included in the comparison table
  • The standard is 10 products per product category

Usually only products that have at least 10 ratings are included in this comparison. With the exception of a maximum of 2 product characteristics, all product information is available from the manufacturer.

Step 5: Relative product evaluation

  • A topic-specific evaluation of an employee serves in this step for the relative arrangement (=placement) of the products in the comparison table and ultimately for evaluation determination
  • This step is limited to the products selected in step 4 and uses the data accumulated in step 3. The individual results are included in the final evaluation via a distribution key.

Step 6: Editorial creation of texts and tables

  • Table development and direct control of data
  • The creation of the respective topic text (we call it ‚main page content‘) related to the comparison table is announced in one of our closed author group

Step 7: Continuous quality control

The focus here is on the following aspects in summary:

  • Up-to-dateness of all data
  • Elimination of possible shortcomings in the user-friendliness of the information presentation
  • Comparison with the current market situation – Have individual products been fundamentally revised? Are new products in the respective category available or are old products no longer in trade?
