I recently built FinCalc AI, a free financial calculator site. But calculators alone do not rank — you need content. So I wrote 34 articles covering everything from mortgage guides to crypto investing.
The Strategy
Each article targets a long-tail keyword that the big sites (NerdWallet, Bankrate) overlook:
- "401k vs Roth IRA guide" instead of "retirement planning"
- "mortgage early payoff guide" instead of "mortgage calculator"
- "side hustle tax guide 2026" instead of "tax tips"
Keeping It Human
Google is getting aggressive about AI content detection. My rules:
- Every article includes personal observations or real examples
- Short paragraphs, varied sentence length
- No "In todays digital landscape..." openings
- Add specific numbers and dates ("2026 tax brackets", "30-year fixed rate")
The Tech Stack
Pure HTML + vanilla JS. No CMS, no frameworks. Each article is a single HTML file. Sitemaps auto-generated. Deployed on Cloudflare Pages.
Results So Far
Still early, but the site is getting indexed and Google is starting to show impressions for long-tail finance queries.
