Best SEO Book

Hello you amazing people, i do hope that things are going positive for you and you are doing well.

I am reading up about SEO, i note that it can be split down into two different segments, mainly on site SEO, including improving website load time, crawlability. Further off site SEO which includes building up links and writing press releases. I am constantly learning about this and wondered if anyone could kindly advice the best SEO book they have read or has been recommended please? This would be really appreciated if you could share any information.

I would be very thankful and appreciate any support you can give. Thank you for your kindness and take care.

I'm currently reading "The Art of SEO: Mastering Search Engine Optimization".
seems solid.
not about link building that much so far but probides a good context.

Seo it's not about book

It's about practise

Bhw forum is better than any book
