The tool uses Google’s internal data to suggest the best keywords for your business and industry. It also has useful features such as country filtering.

It’s easy to pick on Neil Patel because he’s known to do high-performing SEO while sitting in his pajamas. Maybe it’s just because people are jealous and wish they could do the same thing.

Regardless, Mr. Patel recently took over Ubersuggest and gave it a wonderful overall. If it’s been a while since you gave Ubersuggest a try, it may be time to revisit it.
