Free or very low‑cost online options (start immediately)

• Google’s Fundamentals of Digital Marketing (free, certificate from Google) — great for beginners to learn core topics (SEO, analytics, social). Widely recommended as a first step. (iide.co)
• Coursera / IIDE / other MOOC options — several low-cost specializations (pay-per-course or financial aid available) that cover analytics, content, paid ads and more. Good if you prefer self‑paced learning. (iide.co)

Higher‑priced but structured programs (for comparison)

• IIM Tiruchirappalli certificate programs in digital marketing (5–6 months) — higher fee (~₹85k+) but strong brand, faculty delivery and executive-style curriculum; not “affordable” for most but useful if you want a premium credential. (iimtrichy.ac.in)

Quick tips to pick the most cost‑effective course

• Ask for a free demo class and sample project to check hands‑on training quality.
• Confirm how many real projects/internships are included and whether you get help with placements or freelancing leads.
• Check batch size and trainer experience (smaller batches = more attention).
• Compare post‑course support (mentoring, interview prep, placement).
• If budget is tight: start with Google’s free course + one cheap local short course (SEO or Facebook ads) to build a portfolio.

If you want, I can look up current batch dates, contact numbers and exact, up‑to‑date fees for any of these institutes and bring back 2–3 options matched to a specific budget (for example: ≤₹10,000, ₹10–25k, or ₹25–45k).
