Journalism and Mass Communication (BA/BJMC) · Advertising and PR · free study notes for exams, placements and interviews

In short

Public relations is the planned, sustained management of communication between an organisation and the publics on whose goodwill it depends, aimed at mutual understanding rather than at an immediate sale. It is unpaid or "earned" influence - a journalist, regulator, community leader or employee carries the message - so its currency is credibility, not media spend. For BJMC students it is a core paper with heavy theory weight (definitions, Grunig and Hunt's four models, the four-step process, codes of ethics) and heavy application weight (press release writing, campaign plans, crisis case studies). In India the knowledge is used by consultancies (Adfactors, Genesis BCW, Edelman India, Avian WE, Value 360, Concept PR), in-house teams at Tata, Reliance, Infosys, HUL and Zomato, and by government communicators in PIB and the Central Bureau of Communication; interviews test the PRSI code, the Barcelona Principles and at least two Indian crisis cases.

Formulas and examples

Share of Voice (SOV) % = (brand mentions ÷ total category mentions in the same period and media set) × 100
AVE (Advertising Value Equivalent) = total editorial space × card ad rate × multiplier m
space in sq cm (print) or seconds (broadcast); rate in ₹ per sq cm or ₹ per 10 seconds; m = 1 by default, as multipliers are indefensible and Barcelona Principle 5 rejects AVE as "value"
Impressions (OTS) = Σ (circulation or unique visitors of each carrier × readers per copy, if used)
CPM (cost per thousand impressions) = (campaign cost ÷ impressions) × 1,000, in ₹ per 1,000
Net sentiment score = [(positive − negative) ÷ total items] × 100, in %
Favourability % = [(positive + neutral) ÷ total items] × 100
Message penetration % = (items carrying ≥1 key message ÷ total items) × 100
Weighted media quality score = Σ (clips × tier weight) ÷ total clips
Awareness lift (pp) = post-campaign awareness % − pre-campaign awareness %; people newly aware = lift (as a fraction) × target population
PR ROI % = [(value of attributable outcome − campaign cost) ÷ campaign cost] × 100
Engagement rate % = (reactions + comments + shares + saves) ÷ reach × 100

Example 1 - AVE and why it is not value. A product launch earns 10 print clips totalling 2,400 sq cm; the weighted average card rate is ₹900 per sq cm.

Example 2 - Share of voice versus market share. In one month, monitoring of 40 publications records 1,240 category mentions, of which the brand has 186.

Example 3 - Sentiment, favourability and message penetration. 120 items: 54 positive, 48 neutral, 18 negative; 78 items carry at least one of the three key messages.

Total120-204

Average quality = 204 ÷ 120 = 1.70 on a 1-3 scale, i.e. coverage skews mid-tier.

Example 4 - Impressions, CPM and cost per newly aware person. Campaign cost ₹8,00,000 (retainer ₹6,00,000 + OOP ₹2,00,000). Total impressions from print circulation and online uniques = 2,40,00,000.

Example 5 - PR ROI for an education client. A university's admissions PR programme costs ₹12,00,000 for the season. Attributable enquiries (source-coded to earned coverage) = 4,000; enquiry-to-admission conversion = 5%; contribution per admission = ₹15,000.
