Only Our Numbers
Each story starts from a fact sheet built from ETF Tracker's published end-of-day data: returns, assets, fees and holdings. The writer is told to use only those numbers. A program then reads every number in the story and checks it against the fact sheet. A story with a number that does not match is sent back once, then dropped.
A Second Model Checks
A different model reads every claim against the same facts: numbers, directions, rankings, and anything that sounds like a prediction or advice. If it finds a problem the story is not published. The byline says who checked it.
Beginner, Standard and Pro
Standard is the version everyone sees first and the one search engines read. Signed-in readers can switch to Beginner (shorter sentences, terms explained) or Pro (more figures). Every level is rewritten from the same facts and passes the same number check.
Answers First, Kept Current
Every story opens with a short answer and the key facts, and comparison tables are built from our data rather than typed. Answers to reader questions are rewritten in place when the numbers behind them change, and the story shows the date it was last updated.
Not Investment Advice
Stories explain what happened in the data. They are not advice to buy or sell anything. Tell us what worked and what did not with the ratings at the end of each story.
