1. Search engine optimization (SEO)
SEO improves your ranking in unpaid Google results by optimizing content, technical structure and backlinks. It is the highest-ROI channel long term because traffic keeps coming without paying per click. Beginners should start with our guide to what is SEO.
2. AI-SEO and GEO
AI-SEO (also called Generative Engine Optimization) optimizes content so AI tools like ChatGPT, Perplexity and Google AI Overviews cite your brand. As Indians increasingly ask AI for recommendations, appearing in those answers is becoming as important as ranking on page one.
3. Pay-per-click advertising (PPC)
PPC through Google Ads, Meta Ads and YouTube puts you in front of high-intent buyers instantly. You pay only when someone clicks. It is ideal when you need leads fast or are testing a new offer.
4. Social media marketing
Instagram, Facebook, LinkedIn, YouTube and X build brand awareness and community. Organic posting builds trust over time, while paid social boosts reach quickly. LinkedIn works well for B2B in India, while Instagram and YouTube dominate B2C.
5. Content marketing
Blogs, guides, case studies and infographics educate your audience and fuel SEO. Content is the engine behind almost every other channel because it gives people a reason to find, trust and return to you.
6. Email marketing
Email remains one of the highest-ROI channels. Newsletters, offers and automated sequences keep you in front of customers and drive repeat business at very low cost.
7. Affiliate marketing
You pay partners a commission for every sale they generate. It is low-risk because you only pay for results, making it popular with Indian e-commerce and SaaS brands.
8. Influencer marketing
Collaborating with creators, especially micro-influencers in India, delivers authentic reach and credibility. It works well for lifestyle, fashion, food and D2C products.
9. Video marketing
YouTube, Instagram Reels and short-form video drive massive engagement. Video explains complex products quickly and builds a personal connection that text cannot.
10. WhatsApp and SMS marketing
India is a WhatsApp-first country. Broadcast messages, catalogs and automated replies let businesses reach customers directly on the app they check most, making it powerful for local commerce.
Which types should you choose?
- New business, tight budget: SEO + one social channel + WhatsApp.
- Need leads fast: Google Ads + landing page + email follow-up.
- B2B / services: SEO + LinkedIn + content marketing.
