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.

FAQ
How accurate is SimilarSites compared to Similarweb?
SimilarSites provides basic competitor discovery with reasonable accuracy for finding obvious alternatives. Similarweb offers more detailed traffic data and audience insights but costs significantly more.
Can SimilarSites help with link building outreach?
Yes, it can identify sites in your niche that might accept guest posts or partnerships. However, you'll need additional tools like Ahrefs or Hunter.io to find contact information and assess link quality.
Does SimilarSites work for local businesses?
It works better for websites with substantial online presence. For purely local businesses, tools like BrightLocal or Local Falcon provide more relevant competitive intelligence.
How many searches are included in the free plan?
The free plan typically allows 5-10 searches per day with basic results. Pro plans remove these limits and add more detailed data.
Can I use SimilarSites for content research?
It helps identify which sites to research, but you'll need tools like BuzzSumo or Ahrefs Content Explorer to analyze their actual content performance and topics.
