Hello, you are question is very relevant, however without knowing your budget I'm not sure we could answer your question 100% correctly.

I have experience with most of the seo softwares out there and if I have to point out one it should be Licorne AIO.
It does everything that other most expensive softwares do, however, it is times cheaper.
