I'm using Raven SEO Tools. I don't see a way to have it automatically check backlinks weekly (like it does for SERPS) and then be able to see a graph showing 6 month history of total links and/or total ACRank changing over time. Would also be nice if each report indicates new links and has the option to show links that were on the last report but are not longer active.
Is there a cheap/free service out there that does this? Right now I'm having to manually run reports, export and save them.
