I have a tiny two page site: the parameters page and results page. The results page can either work with URL parameters or hidden POST ones. The output is a giant table of data that contains rankings of US cities by some parameters that were defined in the first page.
I am not sure how crawlers could use this page without choosing the parameters (or which ones it would choose), as it is not a standalone page. Should I just block the results page in robots.txt? Will it affect the ranking of my site if I do not block this page (right now the URL to it is very long and contains many parameters)?
