I'm fairly new to SEO and have tried SEMRush and SE Ranking. But since I don't have many SEO clients yet I didn't wanna spend monthly money on SEO tools. So I was very happy to find TrueRanker with lifetime offers. I purchased tier 2 to try it out. Two days later I upgraded to best tier because it looks promising.

What I love:
1) Intuitive adding of keywords
2) keyword cannibalization info
3) android app so I can check changes there easily

What I think needs improvement:
1) position tracking is not always accurate for some of my keywords (while SemRush data is accurate)
2) I really don't like the UI. It feels like 20 years old software (especially compared to other SEO tools)
3) the WordPress plugin didn't allow me to add keywords (errors about invalid token)
4) I'd like to arrange the columns of position tracking tables. For tags I have to scroll a while while in SEMRush tags are directly next to the keywords (which works better)

Overall I'm happy and hope they will keep improving the product over time.
