The ebook stopped working, and not because readers got bored of ebooks.
It stopped working because the thing inside it became free to produce on demand. Your prospect can get a competent twelve page overview of almost any business topic in about forty seconds, without giving anybody a phone number, and they know it.
Gating stopped being an exchange. It became a toll on a road with a bypass.
So the question is not what format to use. It is what you have that cannot be generated, and there are three honest answers: data only you hold, a calculation only they can trigger, and a human paying attention. Everything that still converts is one of those wearing a different hat.
And in India there is a second change layered on top. The thing being exchanged is usually a WhatsApp number rather than an email address, which changes what you should build and what the form should ask.
The thirty second test
Before you commission anything, open any decent chatbot and ask it to produce the thing you were about to gate. “Write me a guide to GST compliance for a small logistics company.”
If what comes back is roughly as useful as your planned asset, you have your answer. Nobody trades a working phone number for something with a free alternative that takes no effort and demands nothing.
A lead magnet is not content. It is something scarce that you are willing to trade.
This is why the checklist and the ebook died together. They were never valuable because of their format, they were valuable because assembling that information used to take a human several hours.
The three things that still have scarcity
Data only you hold. You know what forty clients in your category actually pay, how long their sales cycles run, what their conversion rates look like. Nobody can generate that, because it does not exist anywhere outside your own records. A one page benchmark of real numbers from your own book of business is the most valuable asset most B2B firms in India are sitting on and never publish.
Anonymise it properly, say how many businesses are in the sample, and do not dress up six clients as an industry study.
A calculation only they can trigger. Something that takes their inputs and returns their answer. The information is not scarce, the personalisation is. “What is my cost per acquisition” is a general article. “Your cost per acquisition is Rs 4,200, and here are the two inputs making it that” cannot be produced without them.
A human being paying attention. A teardown of their actual website, their actual ad account, their actual pricing page. Scarce by definition, because your time does not scale, and that is exactly why it converts.
The catch is obvious and you should respect it. If you cannot do fifteen a month, do not advertise it. A promised review that arrives late is worse than no offer, and that is how small firms burn their best list.
What this looks like, concretely
One strong example for five kinds of business, rather than a list of twenty you will not build.
A logistics or warehousing firm. Your actual transit times between the eight routes you run most, with the variance. Everybody publishes promises; nobody publishes observed performance.
A B2B SaaS selling to Indian SMEs. A live calculator for the specific arithmetic your product changes. Not an ROI calculator with invented assumptions, which buyers read as a sales toy, but one real computation they would otherwise do in a spreadsheet.
A chartered accountancy or compliance practice. A deadline calendar for the coming year for their specific business type and state, generated from three questions. Genuinely useful, genuinely tedious to assemble, and it brings them back every quarter.
A manufacturer or industrial supplier. A specification comparison across the options a buyer is actually choosing between, including the ones you do not sell. The credibility comes from the inclusion of competitors, and it is the only version a technical buyer trusts.
An agency or consultancy. A fifteen minute teardown of one specific thing, recorded as a voice note or a short video, delivered on WhatsApp. Low production, high attention, and it demonstrates the thing you are selling rather than describing it.
None of these is a PDF of general advice, and four of the five cannot be copied by reading your landing page.
The exchange is a WhatsApp number
Here is where the standard advice, which is all written for an email-first market, gets India wrong.
A work email is low-commitment currency in a market where everybody keeps a dormant Gmail account for exactly this purpose. A WhatsApp number is higher commitment, which sounds like a reason not to ask and is actually the reason to ask: the people who give it are the ones prepared to have a conversation.
Three consequences.
Ask for fewer fields and make the number the required one. Name and number, company optional. Every extra field is a reason to close the tab, and a designation field is vanity in a business with fifteen employees.
Deliver it in the thread. Not an email with a download link, which loses a share of Indian B2B recipients to spam folders and unchecked inboxes. Send the thing itself on WhatsApp. If it is a benchmark, the key number goes in the message body, not only the attachment.
Say what happens next, in the opt-in, in one plain line. People consent to a conversation far more readily than they consent to an unspecified future.
The follow up behind all of this matters more than the asset, and I have written it up elsewhere rather than repeating it: the first hour after a B2B enquiry and the cadence for leads that go quiet cover the two halves.
Do not gate what should rank
A rule that saves money.
If the content answers a question people type into Google, publish it openly and let it earn traffic for years. Gating it trades a durable asset for a handful of form fills this month.
Gate the derivative instead. Publish the article on how to run the audit; gate the audit itself. Publish the explanation of the benchmark; gate the full dataset with their own position marked in it.
The free version is what gets you found. The gated version is what gets you a conversation. Confusing the two is the most common and most expensive mistake in this whole area.
About consent, because the ground is shifting
Worth knowing while you build a list, and worth knowing accurately, because a lot of what is circulating overstates it.
India’s Digital Personal Data Protection Rules were notified in November 2025, and the substantive obligations, notice and consent and security and breach reporting, commence in May 2027. There is an earlier milestone around November 2026 concerning consent managers, with sources disagreeing on the exact day, and challenges are pending before the Supreme Court. Treat the dates as liable to move and take advice if you are collecting at scale.
Practically: you have roughly eighteen months and nothing stops you building the habit now. Record what each person consented to and when, in the same place you store the number. Retrofitting consent onto a list you have already built is the expensive version, and it is what most companies will be doing in early 2027.
Before lunch
Thirty minutes.
Take the asset you were about to commission and run the thirty second test on it. If a chatbot does it adequately, kill it.
Then open your own records and find one number you know that nobody outside your company knows. Average transit time, median sales cycle, typical cost per lead in your category. One number, with a real sample behind it.
That number, on one page, with a WhatsApp opt-in under it, will out-convert any ebook you were considering, and you can have it live this week.
If you’d like to work out which of the three scarce things your business actually has, drop me a line on email, WhatsApp, phone or LinkedIn and we can have a quick chat, and my notes on lead generation cover where the traffic comes from first. I’m taking on a small number of contracts at the moment, so I’ll tell you straight whether it’s something I could help with.
