What are we doing wrong?

[5TW]

So, we run seo tests via moz, gtmetrix and other sites. On many keywords (NSFW) we appear around 3-7 on the first page.  Our biggest issue is that we are following all the rules moz etc say and we don't move but, but the teo tops sites fail on almost everything we are told to do..... Why?  It confuses us. What are we doing wrong?
