c4c.club

c4c.club is a reciprocal advertising club for founders who want to exchange website traffic without buying ads. Members add a project, paste one script tag and one div, and host another founder’s ad in a sandboxed frame that cannot touch the rest of the page. Approved clicks earn publishers 80% of their credit value, while members can spend credits on an ad with a title and text. Traffic is priced by visitor country across five rate tiers, and new members receive 50 free credits to get started. Built-in anti-cheat checks block self-clicks, cap repeat clicks, flag bot signals and spoofed referrers, and send suspicious activity for human review. The result is a credit-based way for founders to put projects in front of relevant visitors.
