Paid social media ROI asks whether the business return attributable to a campaign exceeds its costs. Reach, clicks and followers can help explain performance, but they do not establish profitability. Start with completed business outcomes and define which revenue and costs belong in the calculation.
ROI vs. ROAS: what is the difference?
ROAS = attributed revenue ÷ advertising spend. It describes revenue relative to media spend. ROI = (attributed revenue − included total costs) ÷ included total costs × 100. State what you include, such as media, creative, management and the cost of delivering the attributed sales. Different cost definitions produce different answers.
Google’s ROI explanation also distinguishes revenue from profit after costs. The calculation principle applies beyond Google Ads; the attribution and reporting setup depend on the channel.
A hypothetical salon campaign example
Suppose a campaign generates $3,000 in attributed revenue from completed appointments. Advertising costs $600, creative and management cost $400, and delivering those appointments costs $1,200. Total included costs are $2,200.
ROAS is $3,000 ÷ $600 = 5. ROI under this cost definition is ($3,000 − $2,200) ÷ $2,200 × 100 = approximately 36%. This is an illustration, not a LaBelle client result or a benchmark. Refunds, additional overhead and uncertain attribution can change the result.
Choose outcomes before metrics
A booking-button click, a lead form and a completed appointment are different events. For a med spa or salon, reconcile inquiries with confirmed and completed appointments. For a boutique studio, separate intro-offer purchases, attendance and later memberships. For interiors businesses, distinguish project inquiries, qualified opportunities and won work. Allow time for the sales cycle.
Use awareness and engagement as supporting evidence
Reach describes the audience exposed to a campaign, while impressions count displays. Click-through rate, comments and shares can explain response. None of these alone proves that the campaign generated profit. Define the denominator for every rate and label whether an engagement rate uses followers, reach or impressions.
Reconcile platform reports with business records
Use campaign links, website measurement and booking or CRM records where appropriate. Document the attribution window and whether the platform includes view-through conversions. Platforms can claim overlapping credit, so adding their attributed revenue together may double-count sales.
Report uncertain or untracked outcomes separately. Do not treat projected lifetime value as cash already received. A campaign can support future demand without demonstrating positive short-term ROI.
What should you improve first?
If qualified people do not click, review the offer and creative. If clicks do not become inquiries, review the landing page and next step. If inquiries do not become customers, inspect fit, availability and follow-up. If sales increase but margins remain weak, review the full cost rather than optimizing only for cheaper clicks.
Compare equivalent periods and show the underlying counts. A large percentage change based on a few appointments is a reason to investigate, not to announce a reliable trend.
