Is fb still a good platform fỏ building pages, or is it become a paid traffic platform now?

Reach isn't dead, but the rules have changed , currently Ai algowithms no longer prioritize large pages or high follower counts. To optimize marketing today, the best approach is to combine organic search with paid advertising for maximum effectiveness

Facebook remains a good platform for building a page, but it is no longer a platform where you can rely primarily on organic traffic as you once could. It has shifted to a "pay-to-amplify" model, rather than a strictly "pay-to-play" one.
