09 What Digital Marketing Costs in India
Real rupee ranges for SEO, paid media, social and content — what drives the number up, what you should expect at each budget, and where agencies hide the fees.
Guides vs blog posts — how to use them
A guide is a pillar: it covers a whole topic comprehensively and links out to focused blog posts on each part. A blog post goes deep on one specific question.
Start with a guide for the full map, then follow its links for the detail you need. Six of the eight map to a single service we run — the marketing funnel guide and the marketing channels guide are both frameworks instead: the funnel tells you which stage is leaking, and marketing channels tells you which platforms to actually spend on. Neither sells one service; both point you to the right one.
Which one should you start with?
Depends on what you need and when you need it.
| Start here | If this is you | What to expect | The matching service |
|---|---|---|---|
| Performance Marketing | You need enquiries this month and have budget to spend | Traffic on day one. It stops when the spend stops. | Performance marketing |
| SEO | You want traffic that compounds and keeps working | Meaningful results in roughly three to six months, then it builds. | SEO services |
| AI Search | You rank on Google but never appear in ChatGPT or AI Overviews | A newer, less contested surface. Early, and moving fast. | AI-SEO / AEO / GEO |
| Link Building | Your content is solid but stronger-linked competitors still outrank you | The slowest, most durable part of SEO. Relevance beats volume. | SEO services — links are half of SEO |
| Conversion Rate Optimization | You already have traffic, but too little of it converts | No new traffic — just more customers from what you already have. | CRO services |
| Marketing Channels | You don't know where to put your first (or next) marketing rupee across platforms | Not one channel — a comparison of seven, plus a framework to pick 2-4. | Several — this guide spans social, search and paid |
| Social Media Marketing | You've already picked social — now you need to run each platform properly | Platform-specific playbooks — sizes, algorithm behaviour and content ideas for each one. | Social media marketing |
| Marketing Funnel | You're already spending across channels and can't tell which stage is leaking | A diagnosis, not a channel. Read it before you move any budget. | None — it's a framework. It tells you which of the others to fund. |
Most businesses that grow well end up running two channels: paid to learn quickly what converts, organic to make that learning permanent. CRO is what makes sure both are landing somewhere that actually closes — the marketing channels guide helps you pick which two, and the social media marketing guide shows you how to actually run the social platforms you pick.
Frequently asked questions
What are Digital Hangover's guides?
They are free, in-depth pillar guides that cover a whole marketing topic end to end — SEO, AI search, performance marketing, link building, the marketing funnel, conversion rate optimization, marketing channels and social media marketing — each linking out to focused articles on every sub-topic. They are built to teach, not to sell, and are updated as things change.
Are the guides free to read?
Yes. No email, no signup, no gate. Every guide is free to read in full, and it will stay that way. If you would rather have the work done for you, each guide points to the matching service — but you never have to click it.
How is a guide different from a blog post?
A guide is a pillar: it maps a whole topic and links out to focused articles on each part. A blog post goes deep on one specific question. Start with the guide for the full picture, then follow its links for the detail you need.
Which guide should I start with?
Start with SEO if you want traffic that compounds over three to six months. Start with performance marketing if you need enquiries this month and have budget to spend. Start with AI search if you rank on Google but never appear in ChatGPT or AI Overviews. Start with link building if your content is solid but stronger-linked competitors still outrank you. Start with conversion rate optimization if you already have traffic but too little of it turns into customers. Start with marketing channels if you're not sure which platform deserves your budget in the first place. Start with social media marketing once you've picked your platforms and need the sizes, algorithm and content playbook for each one. Start with the marketing funnel if you are already spending across several channels and cannot tell which stage is leaking.
