What are the four quadrants Market Explorer uses to map out a website’s industry competitors?

Semrush's Market Explorer tool categorizes competitors into four quadrants based on their market share and growth rate. "Leaders" are established companies with high market share and steady growth. "Established Players" have a significant market share but lower growth rates, indicating maturity. "Growers" are rapidly expanding companies with increasing market share, often disrupting the market. "Niche Players" have a smaller market share and may have varying growth rates, typically focusing on specific segments. "New Players" and "Game Changers" are not standard quadrants used by Market Explorer for competitor mapping.
