I know a lot about on-page SEO but I'm just learning about off-page SEO and backlinking. I've been lurking around on here for a few days, and I notice that there are tons of different types of software and services you pay for by the month to help with your efforts (ie UAW, AMR, BMR, ALN, Scrapebox, Linklicious, Outsourcing writing, etc)
I was wondering how much on average you spend on these tools as well as which ones are the most important. I realize it's an investment that will pay off in the future, but there are so many to choose from it's overwhelming and I don't know which are the best or most important. How much would you recommend that a newbie spend?
Also I'm on a mac, so if you could recommend software that runs on mac I'd appreciate it.
