I'm not necessarily sure there are tools that will directly affect your rankings. I guess if you're using Wordpress the Yoast plugin is pretty good for helping to analyze/correct/optimize the content you're creating. But tools like SEMRush or Moz really only provide data and you need to understand what things to do to act on that data. Honestly, creating quality content (& making sure it's being crawled properly) and building backlinks are the most important tools to ranking.
