Does it work to boost blog pages like this please?

Hi good morning,

just want to know if you have

1- promotions links with blog or pages.
2- exemple you want to promote 500 messages per day it's impossible to get open 500 blogs and send 1 message per day (is there a maximum level per day per blog please) ?

If you promote in free hosting, better to send thousands of pages same day

1- slowly 100 per day
2- or change all pages every day to "get newcontent"

thanks enjoy your day
