Use this method when you already know a **reference organization** and want to find similar organizations. ## How it works * Switch the search type to **Use a similar website** (in Advanced mode). * Enter an organization's website, e.g. `bosch.de` or `vibracoustic.com`. * ISTARI automatically analyses the organization's public digital footprint and generates a feature-rich organization summary. * That summary is then used to scan our master database and return similar organizations. This method is ideal for **competitive benchmarking**, **supplier identification**, or **peer group analysis**.

## Refining a similarity search Once you've added a reference domain, you can steer the result set with up to **three "prioritize"** and **three "avoid"** keywords: * **Add keywords to prioritize**: favour organizations whose profiles mention these terms. Useful when the reference organization has multiple business lines and you care about only one of them. * **Add keywords to avoid**: downweight organizations that mention these terms. Useful to exclude adjacent industries or irrelevant segments. Click the **+** icon next to the domain chip to open the keyword menu, type a keyword and press **Enter** to add it as a pill. Green pills prioritize; red pills avoid. Remove any pill with its **×** button. You can combine similarity search with **Location Filters** and **Other Filters** (keywords, organization size, type, and NACE) for very targeted peer group discovery. ## See also * [Semantic Search](/goi/semantic-search): when you have a market description but no specific reference organization. * [Keyword Search](/goi/keyword-search): when you want exact term matching with no semantic interpretation.
