[opaline]

Is there any tool(s) you can recommend for finding a business-relevant keyword with traffic potential for SEO Writing?
I tried https://ahrefs.com/keywords-explorer. Any suggestions?

I have tried a lot of SEO tools like Ahrefs, Moz, Semrrush, Uber Suggest etc. but Google Keyword Tool happens to be the best for me. It is free and the tool will not only help to find proper keywords but also learn traffic and CPC rate for every keyword. You can use this tool to find business-relevant keywords.
