Is it legal to use SEO Checker?

SEO Checker is designed to analyze publicly available information on websites. It respects robots.txt files and doesn't attempt to access private data. However, always ensure you have the right to analyze a website, especially if it's not your own. When in doubt, consult the website's terms of service or seek legal advice.
