How to Conduct a Gaps and Opportunities report with not provided

[simonsw]

Hi all

Does anyone have any advice on how to conduct a successful gaps and opps audit for your SEO strategy in light of "not provided"? I've been a big fan of Laura Lippay's content audit in finding Gaps and Opps: http://moz.com/blog/finding-gaps-and-opportunities-step-3-of-the-8step-seo-strategy

However I'm keen to understand alternatives to run a successful audit in finding opportunities

Any advice would be much appreciated!

Simon
