Previously, I could use similarweb.com and type in the website URL to check the rough traffic estimation of that website. But now, it looks like similarweb doesn't always do the job. For example, many websites (with average 30K visitors a day) could be analyzed with similarweb but now they don't appear anymore in the search result. Only very big websites appear in the similarweb's search result. What's the solution or alternative to this?
