I want to compare four sites that are doing SEO analysis for websites. I have bought SEO analysis from all four sites and I have made a comparison review of these. I have described the price, outcome, accuracy, process time and more. Is it legal to add all the actual analysis to my review so people can get better understanding? Delicate information will be blacked out on the analysis (website name, some results) so the analysis cannot be used or linked to specific website.
I can't see why not. HOWEVER, just check the terms and conditions of the tools you used to see what you agreed to when you used them.
If you're unsure, maybe limit the content from the actual analysis to parts that are similar, or exactly the same (not necessarily the results, just the terms and such) - since that would definitely be deemed "fair use" since it's a review.
