A founder built 168 free tool pages with a single Python script

A new suite of free trading tools, PropWise, was built on a programmatic SEO strategy from day one. The founder used vanilla HTML and a Python script to target a hyper-specific niche.

A founder targeting proprietary firm traders launched PropWise, a suite of 10 free financial calculators, by generating 168 distinct, SEO-optimized landing pages from a single Python script. The project used no frameworks, no database, and no build step, relying entirely on vanilla HTML, CSS, and JavaScript. The result is a large search engine surface area, built with minimal resources before the first user arrived.

The strategy, detailed in a post on Dev.to, is a direct implementation of programmatic SEO (pSEO) for a narrow, underserved audience. It serves as a playbook for creating a content moat on a zero-dollar budget.

Identifying a narrow, underserved niche

The founder identified that proprietary trading firms, which fund traders but impose strict risk parameters, created a specific user need. Existing financial calculators were generic. They failed to account for rules like the 5% daily drawdown limit imposed by firms like FTMO. Traders needed tools tailored to their precise constraints.

PropWise was built to address this. It includes 10 core tools, such as a Position Size Calculator and a Risk of Ruin Calculator, pre-configured for 12 different prop firms. This specificity is the foundation of the entire SEO strategy.

Programmatic SEO from a Python script

Instead of creating 10 pages for 10 broad keywords, the founder generated 158 additional pages targeting long-tail search queries. A single Python script created pages for every logical combination of the core data. This included 55 pages for specific firms and account sizes (e.g., "FTMO 100K Position Size Calculator") and 66 head-to-head comparison pages (e.g., "FTMO vs FundedNext").

Each generated page was built for search engine crawlers. Pages received unique titles and meta descriptions, structured data using Schema.org (SoftwareApplication, FAQPage), breadcrumb navigation, and heavy internal linking. Critically, the pages are not just empty calculators. They contain pre-calculated data tables, providing immediate value and content for search indexing.

UX details for a specific user

The product design demonstrates a clear understanding of the target user. The interface is a dark theme, mirroring the trading charts traders use all day. Every tool is immediately functional with no signup wall or email gate. The founder's stated goal was to build trust by being useful.

Small details were added to fit the user's workflow. Calculation results can be exported as shareable image cards, optimized for screenshots on Twitter. The interface also includes subtle audio feedback, like a "cha-ching" for positive results, designed to improve the user experience.

What We'd Change

The founder’s self-critique is accurate. A custom Python script is clever but brittle. Using a modern static site generator like Astro or Eleventy would provide the same programmatic capabilities with better maintainability, a larger support community, and a more robust feature set. A custom script becomes a technical liability over time.

The project's distribution model is a single point of failure. It relies entirely on organic search. The founder reports 168 pages have been indexed, but there is no data on traffic or ranking. A strategy with no owned audience (no email list, no social media presence) is vulnerable to any Google algorithm update. Building a simple newsletter or community alongside the tools would create a more resilient asset.

Finally, the project has no stated monetization plan. While this ensures a frictionless user experience, it defines PropWise as a tool, not a business. The most direct path to revenue would be affiliate partnerships with the 12 prop firms featured in the calculators and comparisons. This could be implemented without compromising the core user value.

Landing

The PropWise launch is a playbook for weaponizing programmatic SEO in a niche market with minimal resources. Its success is not yet measured in traffic or revenue, but in the immediate creation of a large, targeted surface area for search engines. The strategy hinges entirely on Google rewarding this depth of content for long-tail keywords. For founders in similarly underserved niches, it demonstrates how a simple script can build a competitive moat before a single user arrives.

The investor read

PropWise is a quintessential bootstrapped, SEO-first project, not a venture-scale business. It signals the persistent opportunity in building highly specific, 'unsexy' tools for niche professional communities. The complete lack of a monetization strategy makes it un-investable in its current form. To attract capital, it would need to demonstrate significant organic traffic and user retention, then layer in a clear revenue model, most likely affiliate fees from the prop firms it profiles. As it stands, PropWise is a well-executed feature that could become a powerful lead-generation asset for a future business, but it is not yet a company.
