After some advice from those with experience.

What is your ranking strategy for tube sites?
Do you try and rank each post?
Or do you have specific pages and keywords you try and rank for?
On pages you’re not trying to rank do you still do your usual SEO practices (unique titles, descriptions, image alt tags etc)?
I’ve read that you shouldn’t try and rank the same keyword over multiple pages. Trying to find different keywords for each page seems a little daunting.
