3. QuestionDB – Best Tool For Creating Valuable Content


QuestionDB serves an instrumental and unique purpose. QuestionDB is a relatively “unknown” keyword research tool unlike most of the tools on this list. While it doesn’t offer detailed metrics like some other tools on this list, this isn’t necessarily a disadvantage.
However, QuestionDB is the perfect keyword research option for people who want to create meaningful content that serves their customers. As you know, the benefits that accompany creating excellent content are virtually endless: better user interaction/experience, more social shares, more backlinks, more traffic, more trust, and eventually much more money.

Pros
- Allows you to cover particular topics in significantly greater detail, helping you to create more authoritative content; this can situate you as an expert within your niche.
- Helps you to create concise and optimized answers for common user questions. This will enable you to satisfy search intent better and appear in Google’s featured snippets.
- No email or credit card is required to sign up. It’s completely free.
Cons
- While finding questions to answer through this tool is fantastic, the keyword ideas are not usually as exciting or as helpful.
- QuestionDB doesn’t provide any specific search-related metrics. This means there is no search volume, keyword difficulty, historical data, etc.
