They convert at lower rates than generic ebooks but produce leads that convert to opportunity at two to four times the rate, because completing them is itself a qualification event. Rank magnets by downstream lead-to-opportunity rate, not by form conversion rate. ## Key takeaways - Generic ebooks convert visitors best and produce the worst leads, which is why they persist and why they fail. - Calculators and assessments convert lower on the form and far higher on lead to opportunity. - If a magnet does not require the reader to disclose their situation, it cannot qualify anyone. - Production cost ranges from an afternoon for a spreadsheet to six weeks for a real benchmark report. - Match magnet to page intent: a pricing page visitor wants an ROI model, not a trends ebook. - Five formats are past their useful life, including the generic industry trends report nobody reads. --- Rank lead magnets by conversion rate and you will end up with a library of ebooks and a sales team that ignores your leads. The highest-converting offers are reliably the worst-qualifying offers, because the easiest thing to say yes to is the thing that asks nothing of you. So this list ranks by downstream lead to opportunity rate. Eighteen formats, with build cost, shelf life and the page intent each one belongs on, plus the five I would retire this quarter. ## The ranking method Four columns. Form conversion rate, which is what most teams optimise. Build cost in working days. Shelf life, meaning how long before the asset needs rewriting. And lead to opportunity rate, which is the column that decides the ranking. The principle underneath: a magnet qualifies in proportion to how much the reader has to reveal to get it. Type your email to download a PDF and you have revealed nothing. Answer eleven questions about your current stack, team size and process to get a maturity score, and you have handed sales a briefing document. The definition and its variants are in [lead magnet](/glossary/lead-magnet/). Does the reader have to disclose their situation to get value from this? If no, it will produce leads your sales team will not call twice. ## The eighteen formats, ranked Read the first and last columns together. The ebook converts nearly six times better on the form and produces roughly a quarter of the opportunity rate. That is the entire argument of this page in one comparison. ## The top five, with examples **ROI or cost model calculator.** The buyer enters their own numbers and receives a number they will quote internally. Vanta-style compliance vendors do this well because audit cost is a number a CFO already worries about. Build it once, maintain it annually, and it will outlive three content strategies. **Maturity assessment with a score.** Ten to fifteen questions, a score, a named tier and specific next steps per tier. HubSpot's grader products are the template here. The scoring output gives sales a genuine opening line rather than "I saw you downloaded our guide". **Free grader or audit tool.** Enter a domain or connect an account, get a report. The most expensive format to build and the most durable. Ahrefs and similar tools use free graders as a permanent acquisition layer, and the links these earn are worth as much as the leads. **Interactive product tour.** Not strictly a magnet, and it outperforms most of them. Let people see the product before asking for anything, then gate step four. **Live teardown or audit offer.** The lowest form conversion rate on the list and the highest lead to opportunity rate. It is a human offering an hour of real work. Two percent of the right page's visitors will take it, and nearly half of those become opportunities. **44%** Lead to opportunity rate for a live teardown or audit offer ## The middle of the list **Original benchmark report.** Works when you genuinely have the data, usually from your own product. Thirty days of work and it dates within a year. Klaviyo's ecommerce benchmarks are the model: data only they have, published clearly, cited everywhere. **Vendor comparison spreadsheet.** A neutral feature and pricing grid across you and five competitors. Uncomfortable to publish, which is why it works. **Working template with real data.** A financial model, a campaign brief, a QBR deck, populated with a realistic example rather than dummy text. Miro and Notion both grew partly on template libraries. **Internal-use checklist.** An afternoon of work, 18 percent conversion, decent qualification. The best ratio of value to effort on the whole list. **Notion or Airtable workspace.** Duplicable, useful, and it puts your brand in the tool your buyer works in daily. **Email mini course.** Five days, five emails, one lesson each. Good for slow-burn categories where the buyer is not ready. Poor for urgent problems. **Expert or vendor directory.** Builds links and repeat visits. Slow to produce leads. **Raw data set for download.** Niche, and analysts and journalists love it, which is where the value sits rather than in direct pipeline. ## Matching magnet to page intent The same magnet on the wrong page produces nothing. This table matters more than the ranking. | Page the visitor is on | What they are thinking | The right magnet | | --- | --- | --- | | Pricing page | Can I justify this internally | ROI model, internal buy-in deck | | Comparison or alternatives page | Which of these three do I pick | Vendor comparison spreadsheet | | Category or best-of page | What are my options at all | Maturity assessment, directory | | Blog post on a specific problem | How do I fix this today | Checklist, template, swipe file | | Documentation or integration page | Will this work with our stack | Technical checklist, sandbox access | | Customer story page | Would this work for a company like us | Benchmark report, calculator | | Homepage | Who are these people | Interactive product tour | A trends ebook fits none of those rows, which is a useful thing to notice about trends ebooks. The wider content architecture this sits inside is in [B2B SaaS content marketing](/guides/b2b-saas-content-marketing/). ## The five formats to retire - **The general industry ebook.** An AI assistant summarises the category in ten seconds for free. Your 40 page overview competes with that and loses. - **The gated webinar replay with no index.** Nobody watches 47 minutes to find the four minutes they need. Publish it ungated with timestamps and gate the workbook. - **The trends report you do not have data for.** Predictions assembled from other people's reports. Everyone can tell. - **The "ultimate" resource bundle.** Nine assets zipped together, which signals that none of them was worth downloading alone. - **The gated case study.** Your customer agreed to be a public reference. Gating their story wastes the asset and irritates them. All five convert well on the form, so the dashboard defends them. Nobody measures lead to opportunity by magnet, so nobody sees the cost. Run that report once and four of these will be dead by Friday. ## Building one properly **From idea to live magnet in three weeks** That sixth step is where most of the value is realised, and it is the one that gets dropped when the launch runs late. A calculator whose inputs never reach the CRM is an expensive brochure. The outbound use of that data is covered in [outbound lead generation for SaaS](/guides/saas-outbound-lead-generation/). ## What to do next Run a lead to opportunity report by magnet for the last two full quarters. Retire everything below half your site average, then build one calculator or assessment for the highest-intent page you own.

An interactive calculator or assessment tied to a decision your buyer is currently making. It converts a smaller share of visitors than a downloadable ebook but the people who finish it have told you their team size, budget, current tooling or maturity level, which makes the lead routable and the follow-up specific. Build cost is higher and shelf life is measured in years. ### Do ebooks still work as lead magnets in 2026? Specific ones do. A 40 page general industry ebook does not, because buyers can get the same overview from an AI assistant in ten seconds without giving up an email address. A narrow, opinionated document that only your company could have written still works, particularly when it contains data or a process nobody else publishes. ### What conversion rate should a B2B lead magnet get? On a relevant page with a well-matched offer, 8 to 20 percent of page visitors for a simple download, and 3 to 8 percent for an interactive tool that takes several minutes. Both figures depend far more on page intent than on the magnet itself. The same ebook on a pricing page and a blog post will differ by a factor of five. ### Should lead magnets be gated or ungated? Gate anything that costs real money to produce and carries genuine scarcity, such as an original data set or a working model. Ungate anything that exists mainly to demonstrate competence, such as a template or a checklist, and capture the email on the follow-up instead. Ungated assets earn links and citations that gated assets never will. ### How do I know if a lead magnet is producing good leads? Measure lead to opportunity rate by magnet, at a cohort level, and compare against your site average. Most teams never do this, which is how a magnet producing 200 leads a month and one opportunity a quarter survives for two years. If a magnet is below half your site average on lead to opportunity, retire it. ### How long does it take to build a good lead magnet? A spreadsheet or checklist takes an afternoon. A template pack takes a week. A calculator takes two to four weeks of design and engineering. A genuine benchmark report takes six weeks plus a data source you already own. Budget the calculator once and you will outperform four quarters of ebooks.
