SimilarSites
Competitive IntelligenceFind competitor and alternative websites quickly
Overview
SimilarSites is a straightforward competitive intelligence tool that does one thing well: finding websites similar to any domain you enter. Founded in 2009 by a team in Tel Aviv, it predates many modern SEO platforms and focuses specifically on competitor discovery rather than comprehensive analysis. The tool uses traffic patterns, content similarity, and audience overlap to identify genuine alternatives to any website.
Unlike comprehensive platforms like Similarweb or SEMrush, SimilarSites keeps things simple. You enter a domain, get a list of similar sites, along with basic traffic estimates and categorization. It's particularly useful for initial competitive research when you need to quickly identify who else operates in your space or find potential link building targets.
The tool has maintained relevance by staying focused on its core function while adding useful features like traffic metrics, keyword insights, and export capabilities. It sits between free tools like Google's "related:" operator (which Google discontinued) and expensive enterprise platforms, offering a middle-ground solution for competitor discovery.
