CPM ÷ 1,000
At 1.5% CTR
CPM ÷ (CTR% × 10)
CPM = (Total cost ÷ Impressions) × 1,000
($250 ÷ 50,000) × 1,000 = $5
Effective CPC = $5 ÷ (1.5 × 10) = $0.33
At $5 CPM, 100,000 organic impressions from SEO content are worth about $500 in display-media equivalent — without paying for every thousand views.
RankOrg fills your site with SEO content that compounds organic impressions — reach you don't rebuy every month at a CPM.
Use CPM when the goal is reach and frequency. For direct response, also model CPC and CPA so cheap impressions don't hide expensive clicks.
CPC ≈ CPM ÷ (CTR% × 10). A $10 CPM at 2% CTR is about $0.50 CPC — use this when comparing channels that report different metrics.
SERP and content impressions from SEO don't bill per thousand views. Sustained publishing lowers blended CPM across the whole acquisition mix.
