SEO tips for writing and designing pages

Hi, I wanted to ask you if anyone had the time / desire to give me some advice on how to structure and write the pages of my website at SEO level

my idea would be to show you a page that is already on the site
if you can give me advice on that, then I’ll arrange the rest (the pages of my site are all structured the same)

Thanks in advance

The page I need help with: [log in to see the link]
