did not do any serious keyword research since 2012 and I think many things changed, so hopefully there are some serious and good keyword research tools out there.
I need something that will help me with ideas for new KWs. I have a huge niche with about 4 main KWs, from each of it about 10 smaller KWs. I need to go deeper into long-tails.
Can anybody suggest anything good?
It would be fine to find the most relevant long-tail KWs to my terms, traffic volume, maybe some "competition" (even I do not trust online metrics).
Thanks a lot guys!
