Analysis Workflow

Analyze social media campaign performance:

1. Validate input data completeness (reach > 0, dates valid)
2. Calculate engagement metrics per post
3. Aggregate campaign-level metrics
4. Calculate ROI if ad spend provided
5. Compare against platform benchmarks
6. Identify top and bottom performers
7. Generate recommendations
8. Validation: Engagement rate < 100%, ROI matches spend data

Input Requirements

Field	Required	Description
platform	Yes	instagram, facebook, twitter, linkedin, tiktok
posts[]	Yes	Array of post data
posts[].likes	Yes	Like/reaction count
posts[].comments	Yes	Comment count
posts[].reach	Yes	Unique users reached
posts[].impressions	No	Total views
posts[].shares	No	Share/retweet count
posts[].saves	No	Save/bookmark count
posts[].clicks	No	Link clicks
total_spend	No	Ad spend (for ROI)

Data Validation Checks

Before analysis, verify:

• Reach > 0 for all posts (avoid division by zero)
• Engagement counts are non-negative
• Date range is valid (start < end)
• Platform is recognized
• Spend > 0 if ROI requested

Engagement Metrics

Engagement Rate Calculation

Engagement Rate = (Likes + Comments + Shares + Saves) / Reach × 100

Metric Definitions

Metric	Formula	Interpretation
Engagement Rate	Engagements / Reach × 100	Audience interaction level
CTR	Clicks / Impressions × 100	Content click appeal
Reach Rate	Reach / Followers × 100	Content distribution
Virality Rate	Shares / Impressions × 100	Share-worthiness
Save Rate	Saves / Reach × 100	Content value

Performance Categories

Rating	Engagement Rate	Action
Excellent	> 6%	Scale and replicate
Good	3-6%	Optimize and expand
Average	1-3%	Test improvements
Poor	< 1%	Analyze and pivot

ROI Calculation

Calculate return on ad spend:

1. Sum total engagements across posts
2. Calculate cost per engagement (CPE)
3. Calculate cost per click (CPC) if clicks available
4. Estimate engagement value using benchmark rates
5. Calculate ROI percentage
6. Validation: ROI = (Value - Spend) / Spend × 100

ROI Formulas

Metric	Formula
Cost Per Engagement (CPE)	Total Spend / Total Engagements
Cost Per Click (CPC)	Total Spend / Total Clicks
Cost Per Thousand (CPM)	(Spend / Impressions) × 1000
Return on Ad Spend (ROAS)	Revenue / Ad Spend

Engagement Value Estimates

Action	Value	Rationale
Like	$0.50	Brand awareness
Comment	$2.00	Active engagement
Share	$5.00	Amplification
Save	$3.00	Intent signal
Click	$1.50	Traffic value

ROI Interpretation

ROI %	Rating	Recommendation
> 500%	Excellent	Scale budget significantly
200-500%	Good	Increase budget moderately
100-200%	Acceptable	Optimize before scaling
0-100%	Break-even	Review targeting and creative
< 0%	Negative	Pause and restructure
