1/ keyword tool: I have tried all the keyword tools out there, and WriterZen is by far the best. I love how it does the keyword research for me, and it's so easy to find what I am looking for with their user-friendly interface.

I tested the keyword "dog training" in the US location and got over 4600 keyword ideas while only getting 1600 from getkeywords.io

2/ Content Creator tool: You just need to improve a bit more in the ability to scan the article outline to the H4 tag, currently only scan to the H2 tag. Finally, add the team member feature and everything will be perfect.

3/ Conclusion: I can't imagine not having this tool in my arsenal. It's perfect!
