LinkTRX is a 1:1 backlink exchange for website builders. Share a site where others can place a link. After a manual review you earn one credit, and one credit unlocks one other listing, including the URL and a real example. Links you have already opened stay free. One listing is free every day. Track the sites you still need to publish on, permanently skip platforms that do not fit, and leave a note for the next person. Fair, reviewed link building instead of bulk outreach.
