Hi @chicuae - many thanks for your reply, it's much appreciated.
Just to give an example, this image shows the top 10 SERPs for the keyword "care home furniture" in the UK: https://i.ibb.co/23pr418/care-home-furniture.png
The website ranked #4 on that screenshot has a Page Authority of 36 and a Domain Authority of 5. How can the Page Authority be so much higher than the Domain Authority? Surely any backlinks pointing to that specific page (the homepage) would also be factored into the Domain Authority?
Compare that to another website that has the homepage in the SERPs i.e. https://www.carechair.co.uk/ in position 6, their PA and DA and much closer to each other.
You mentioned that DA takes into account backlinks "as well as other factors". What are those other factors?
For PA, you mentioned that includes backlinks pointing to a particular page, as well as the content relevance and internal linking structure. What specifically about the internal linking structure could cause such a big difference between the PA and DA of the homepage?
Many thanks in advance.
John
