Let me know if you can let me see the domain?

Hi, thanks for taking the time to answer, but honestly this does not address the point I am trying to make. Lets see if I can be more clear with an example.Let's suppose I have an affiliate WordPress website that reviews cameras. OPTION 1: My URLs at the moment are "POST" type: /best-camera /best-sony-camera /best-fujifilm-camera /fujifilm-xt20-review /canon-60d-review /nikkon-750d-review OPTION 2: Other websites in my niche have also a wordpress website and they posted the same topics as "PAGE" type: /best-camera /best-camera/sony /best-camera/fujifilm /review/fujifilm-xt20 /review/canon-60d /review/nikkon-750d Here, best sony camera and fujifilm review are wordpress child pages of the parent pages review and best cameras Question: How much SEO advantage do these people (the PAGE type people - option 2) have over me (POST type website - option 1)? Is it gonna be worthwhile for me to re-design my website and have all my option 1 re-organized as option 2? When I started my website many years ago I didn't have any idea what I was doing so I just did it all as posts. But these people clearly are experienced and started the website with the right foot. So I am wondering if it's gonna be worthwhile for me to transform my website structure from option 1 into option 2.

Hi, I read and watched the video, but I don't see why I should add dofollow links? how does it help?

Your "authority " is on your domain - on your subdomain "www" (or without) but not on a new sub-domain. So if you want to take the authority with you, you need to pick a subfolder. Thatswhy -> no difference between sub-domain or new domain in your case. Also the reason why it should be possible to pick a subdomain, what i still wont do But if you link them well, you will benefit from your domain. Ok in this point, it looks more organic to link to a subdomain than to a different one.  But e.g. linking to a new domain wich is yours in the footer  is (according to john mueller) ok, because google is clever enough to know that this is not sponsored or spam, but one of yours.
