If lookalike company searches aren’t returning results, it’s usually due to missing or invalid company identifiers. Make sure you’re entering valid company domains (like [lusha.com](https://lusha.com), not the full URL) or company profile URLs. Double-check that your input fields are set up correctly in your table—Clay needs either a domain or a company profile URL to run the search. If you’re still seeing no results, try simplifying your filters or running the search with just the domain to rule out filter issues. [1] [2] [3]
