Package Landing Page Design Breakdowns in Google Sheets

Everyone building a landing page has the same question: what actually works? They read a few blog posts, copy a competitor, and ship something that converts at a rate they never measure.

The people who know the answer have run the tests. Most of them don't write it down anywhere anyone can use.

The idea is a Google Sheet of landing page design breakdowns: what won the A/B tests, the tools and metrics for running your own, and fill-in-the-blank micro copy templates. It's one of my 100 business ideas in Google Sheets, and it's a strong one for anyone who has done conversion work.

The idea

Create an epic checklist of the winners of A/B tests, the resources to run A/B tests, and the metrics involved in testing landing page designs. The breakdowns are the draw: this headline beat that headline, this button placement beat that one, and here is why. Collect enough of them and patterns appear that no single test would show.

Then add templates and formats for micro copy. Button text, form labels, headline structures, trust lines under the call to action. Build them so a user fills in a few key terms (product, outcome, audience) and the sheet assembles the best micro copy for them to use. Include the A/B pairs too, so they have a variant ready to test instead of a single guess.

The sheet could include pre-written formulas that help users build and measure an effective landing page.

A conversion rate formula that takes visitors and conversions and returns the percentage, with a benchmark column next to it so users can see whether 2 percent is good for their kind of page.

An A/B testing formula that takes the visitors and conversions for two variants and tells the user which one is winning and by how much. A basic significance check is possible in Sheets, and even a simple one stops people calling a test after 40 visitors.

A CTA button formula that assembles button text from the user's chosen verb, object, and outcome, and shows a few variants side by side for testing.

An SEO formula section: title length checks, meta description length checks, and a keyword presence check across the copy the user pastes in. Less magic than the name suggests, but genuinely useful when you're shipping a page and the title is 74 characters.

How to build it in Google Sheets

1. Breakdowns. One row per test. Columns: Page Type, Element Tested (headline, CTA, form, layout, social proof), Variant A, Variant B, Winner, Lift, Why It Won, Source, Screenshot Link.
2. Checklist. Every principle that showed up as a winner, as a checkbox list. Columns: Principle, Applies To, Priority, Done.
3. Micro Copy Builder. Input cells for Product, Audience, Outcome, and Verb. Below, formulas that assemble headlines, CTA text, and trust lines from those inputs.
4. Test Calculator. Inputs for Variant A visitors and conversions, Variant B visitors and conversions. Outputs: each conversion rate, relative lift, and a simple significance indicator.
5. Tools and Metrics. A list of testing tools, analytics setups, and the metrics worth tracking, with a one-line note on when to use each.

• Data validation dropdowns on Page Type and Element Tested, so a user can filter breakdowns to only the kind of page they're building.
• FILTER on a front tab to show the breakdowns and checklist items that match the selected page type.
• Text formulas in the Micro Copy Builder, for example ="Get "&B2&" in "&B4 where B2 is the outcome and B4 is the timeframe. Simple, but it produces real options quickly.
• Conditional formatting on the Test Calculator so the winning variant highlights green and a sample size that's too small shows a warning color.
• Checkboxes on the Checklist so a user can audit their page before launch.

Who pays for it, and how to sell it

The buyer is a founder launching a product, a freelance marketer building pages for clients, or a small in-house growth person who doesn't have time to read fifty case studies. They pay for the breakdowns (research they can't do themselves) and the builder (copy they'd otherwise stare at for an hour).

Price the breakdowns and checklist as a one-time template. Price the growing version, where you add new breakdowns every month, as a subscription. The service on top is a landing page teardown: they send the URL, you send back the sheet with their page scored against the checklist.

Gumroad handles the one-time sale. For the subscription, or to avoid manually sharing the sheet with every buyer, use OnlySheets, which grants access to the Google Sheet automatically on purchase.

First 10 customers: publish one breakdown a week somewhere founders read, whether that's a newsletter, a community, or your own feed. Each breakdown is a row from the sheet, with the screenshot and the why. At the end of each one, mention the sheet. Ten breakdowns in ten weeks should find ten buyers, and you'll have grown the product at the same time.
