First off I'd like to thank you all for the amazing information over the years. I've been a bit of a leech and I hope to start contributing. However, I was hoping that someone could point me to knowledgebase or give me some pointers on the best tools to start with SEOing a site/company and mobile app I created. I was looking at SEONuke X, but I wanted to get your feedback on which tools I should start with or share the tools they use and why they think they're great. I tried searching but I'm still a bit lost.
