its very difficult to get likes for your pages sometimes but i have seen a page on facebook to get free likes.
click on this link : https://www.facebook.com/exchangepagelikes
first like this page then like other pages which are shared by admin on this page .... then Message your page URL ADDRESS to its page admin via page message option ... then admin will see that have you followed rules if yes then admin will share your page on thousands of other pages and u will get thousands of likes even within hour .........
