Where do these ratings come from?We analyze the text of client reviews published on verified platforms. The categories reflect patterns in past client feedback, not predictions for your project. Companies with fewer reviews may display more "Not enough data" cells, which indicates limited review coverage rather than weaker performance.

What does each level mean?Strong indicates consistent praise across reviews. Mixed shows both positive and negative feedback. Weak means criticism outweighs praise. Not enough data means too few reviews mention the category to draw a conclusion.

Can a company pay to improve its rating?No. Category ratings cannot be purchased, and featured placement does not influence them.
