This is definitely a tricky question as many platforms and services for SEO reporting are out of date and not current with the newest search engine algorithm changes. As there could be 100 or more algorithm changes on Google alone, each month, you need a solid platform that is reliable and timely.

The two that I recommend you check out are Moz.com and Raven Tools. Moz is my preferred platform as the team is always on the cusp of breaking SEO news and changes.
