sbiewald369929d#2 is unethical and can result in you being ranked down by Google. Also, if you want to have the hidden pages indexed by Google, they are indexed and users might visit them - if you redirect your users away, Google will detect this eventually and not count the pages.
Still, it might work, but more or better content does improve you ranking as well (and will not have side effects).
If you encourage sharing your site (e.g. on social media), your rank should grow as well (because of more pages linking to you).
