G2 reviewers broadly consider TikTok Ads good value, particularly for reach and CPM efficiency. Multiple reviewers across small business and mid-market segments highlight CPMs and cost-per-view figures significantly lower than Meta and other platforms. G2 users in apparel, marketing, and consumer goods report strong ROAS and affordable audience scale. However, value concerns surface consistently: several G2 reviewers note rising costs over time, unpredictable conversion campaign performance, and heavy dependence on strong creative. Reviewers in education and building materials flag cost-effectiveness risks for smaller budgets. Overall, G2 reviews of TikTok Ads indicate solid value for awareness and upper-funnel goals, with diminishing returns for direct-response objectives.
