Taboola — Recommended for Scale and Premium Publisher Reach
Taboola's advertiser platform, now called Realize, reaches about 600 million daily active users by the company's own count. Bidding is cost-per-click, and budgets are sized from the CPA goal because no fixed minimum is published. The trade-off is the learning phase: documentation advises running a first campaign for at least 7 to 10 days. Yahoo sells its native inventory through Taboola after closing Gemini.
Verdict: the strongest fit when the budget can fund a learning phase against a defined CPA.
