Digital Marketing Complete Guide: Strategy, SEO, Google and Meta Ads, Social, Email, WhatsApp, Analytics and AI

The marketing funnel and strategy

SEO (search engine optimisation)

pages = [("Title tag", "Learn AI Product Management in 12 Weeks | Live Course, Gurgaon & Online", 60),
         ("Meta description", "Become an AI-first PM with live classes, 25+ case studies, a free 570-page handbook and job support. Next cohort starts soon - book a free counselling call.", 155)]
for name, text, limit in pages:
    print(f"{name}: {len(text)} characters (limit about {limit}) ->", "OK" if len(text) <= limit else "too long, Google may cut it")

Title tag: 71 characters (limit about 60) -> too long, Google may cut it
Meta description: 156 characters (limit about 155) -> too long, Google may cut it

Google Ads

Key ideas: match types (broad with smart bidding, phrase, exact), negative keywords, responsive search ads (up to 15 headlines and 4 descriptions), Quality Score (expected CTR, ad relevance, landing page experience), smart bidding (Maximise conversions, Target CPA, Target ROAS) once you have conversion data, and conversion tracking with Google tag / GA4 and enhanced conversions.

Meta Ads (Facebook and Instagram)

• Objectives: Awareness, Traffic, Engagement, Leads, App promotion, Sales.
• Structure: Campaign (objective, budget with Advantage+ campaign budget) → Ad set (audience, placements, optimisation event) → Ads (creatives).
• Audiences: broad targeting with strong creatives often wins; custom audiences (site visitors, customer lists) and lookalikes; Advantage+ automation.
• Tracking: Meta Pixel + Conversions API (server-side) for reliable conversion data.
• Creatives are the biggest lever: hook in the first 2 seconds, vertical video for Reels and Stories, captions, clear offer and CTA, test 3–5 concepts at a time.
• Lead ads with instant forms and a WhatsApp or call follow-up within minutes.

spend, impressions, clicks, leads, sales, revenue = 50_000, 400_000, 6_000, 300, 30, 1_80_000
print(f"CPM ₹{spend / impressions * 1000:.0f} | CTR {clicks / impressions:.2%} | CPC ₹{spend / clicks:.1f}")
print(f"CPL ₹{spend / leads:.0f} | lead-to-sale {sales / leads:.0%} | CAC ₹{spend / sales:,.0f} | ROAS {revenue / spend:.1f}x")

CPM ₹125 | CTR 1.50% | CPC ₹8.3
CPL ₹167 | lead-to-sale 10% | CAC ₹1,667 | ROAS 3.6x

Social media and influencers

Plan content pillars (educate, entertain, prove, sell), a weekly calendar, and repurpose one long piece into many short ones. For influencers: choose fit over follower count (micro-creators often convert better), brief clearly, track with unique codes and UTMs, and follow ASCI guidelines (#ad / disclosure labels).

Email and WhatsApp marketing

• Email: welcome series, nurture sequences, newsletters, abandoned cart, win-back; segment by behaviour; authenticate the domain (SPF, DKIM, DMARC) and follow Gmail/Yahoo bulk-sender rules.
• WhatsApp Business Platform: opt-in first; approved templates for marketing, utility and authentication messages; click-to-WhatsApp ads; chatbots for FAQs and lead qualification; respect frequency.
• Consent: the DPDP Act requires clear notice and consent and easy withdrawal; SMS needs DLT-registered headers and templates.

Analytics and attribution

from urllib.parse import urlencode
base = "https://www.skillnavora.in/program/genai-launchpad.html"
utm = {"utm_source": "instagram", "utm_medium": "paid_social", "utm_campaign": "genai_nov26", "utm_content": "reel_hook_a"}
print(base + "?" + urlencode(utm))

https://www.skillnavora.in/program/genai-launchpad.html?utm_source=instagram&utm_medium=paid_social&utm_campaign=genai_nov26&utm_content=reel_hook_a

Attribution: last-click undervalues awareness; GA4's data-driven attribution, incrementality tests (geo or hold-out), and marketing mix modelling (MMM, for example Google's Meridian or Meta's Robyn) give a fuller picture.

Conversion rate optimisation (CRO)

Landing page checklist: one goal and one CTA, headline that matches the ad, proof (reviews, logos, numbers), clear price or "book a call", short forms, fast mobile load, WhatsApp button, FAQs, urgency only if real. Run A/B tests with enough traffic and one change at a time.

import math
visitors_each, conv_a, conv_b = 4000, 0.040, 0.050
se = math.sqrt(conv_a * (1 - conv_a) / visitors_each + conv_b * (1 - conv_b) / visitors_each)
z = (conv_b - conv_a) / se
print(f"lift {conv_b / conv_a - 1:.0%}, z = {z:.2f} ->", "significant at 95%" if abs(z) > 1.96 else "not significant yet; keep testing")

lift 25%, z = 2.16 -> significant at 95%

Budgeting with unit economics

aov, gross_margin, repeat_orders = 2_500, 0.45, 2.2
ltv = aov * gross_margin * repeat_orders
for cac in (600, 1200, 2000):
    print(f"CAC ₹{cac:5,d}: LTV ₹{ltv:,.0f}, LTV/CAC = {ltv / cac:.1f}", "-> healthy" if ltv / cac >= 3 else "-> fix CAC or LTV")

CAC ₹  600: LTV ₹2,475, LTV/CAC = 4.1 -> healthy
CAC ₹1,200: LTV ₹2,475, LTV/CAC = 2.1 -> fix CAC or LTV
CAC ₹2,000: LTV ₹2,475, LTV/CAC = 1.2 -> fix CAC or LTV

Start with a test budget split across 2–3 channels, kill losers quickly, scale winners gradually (20–30% budget steps), and keep 10–20% for new experiments.
