Auto SEO software is fine for doing the tedious information gathering for you, but apart from that it isn't worth a toss!
Many years ago, when y dog could SEO a page to the #1 spot (spot is my dogs name)

autosoftware would get the results. it will STILL get you resuklts if the phrase is not at all competitive, but the moemnt you get any sort of competition then forget it.
SEO is now way beyond counting words on a page, SEO by numbers started to fail about 5 years or so ago. Today you have to SEO with 20% Science, and 80% grunt and gut. The gut to tell you what needs doing, and the grunt to do it.
SEO software is great for checking and assembling the search data etc, but beyond that, waste of time. Swim with the tuna, and you get caught in the nets, matters not that you are a dolphin.
