Hi Jessica,
Use many tools from MOZ, ahrefs, SEMRush, and the list goes on. My favorite is Searchlight. Many reasons, but the platform allows you to go from the eye of the eagle to the eye of an ant across your sites. Too many features to write about but I did write a detailed review here: https://www.trustradius.com/reviews/conductor-searchlight-2015-09-25-08-43-15
The customer service is amazing. They are very helpful and proactive. Not unusual to get a note about a new feature that they not only know I'm interest in but they then help me build out for my business.
Hope the expanded review helps!
Josepf
