General information, not advice
Everything on this site is published for general information and commentary. It isn’t professional advice of any kind, including SEO, legal or financial advice. Decisions you make based on anything here are your own, and you should take advice specific to your situation before acting.
Accuracy and dates
Research on this site reports what named public sources said on a stated date. Those sources change, so each finding describes a source as it was on that date. Each study publishes its raw data and its method, and the method note sets out what this site does and does not claim. Where I interpret the data, for example why a publisher might have made a choice, that is my honest opinion based on the facts published alongside it. The wording makes it clear when I’m giving analysis.
About the organisations named here
Research here names real companies, because the data is about them. Factual statements about those companies are drawn from their own publicly available files and from cited third-party sources, read on stated dates, with the underlying data published for anyone to check. Trademarks and brand names belong to their owners. Nothing on this site implies that any named organisation is affiliated with, endorses, or has reviewed this site.
Affiliate links
Some links on this site are affiliate links, which means I may earn a commission if you buy through them, at no extra cost to you. Affiliate links are labelled where they appear and listed on the What I use page. They have no effect on what my research measures or reports.
Corrections
If you believe something here is factually wrong, contact me with the page and the error. I will check it against the source promptly; verified errors are corrected with a dated note on the page.
External links
Links to other sites are provided for reference. I don’t control them and am not responsible for their content.
Liability
This site and its content are provided “as is”, without warranties of any kind. To the fullest extent permitted by law, I accept no liability for any loss or damage arising from reliance on anything published here. Nothing in this notice excludes any liability that cannot be excluded by law.
