Quick answer

Source verification is the habit of opening each source an AI tool cites and finding the exact claim or number on that page yourself. A citation only tells you where to look; verifying it tells you the claim is really there, current, and means what the AI says it means.

## Why it matters for a small business

AI research tools can cite a real page for a number that is not on it, mix up two reports, or use an old figure. Market sizes are a common trap: different analysts measure different things, so their numbers disagree.

Checking two or three sources takes a few minutes and catches most of these problems before a wrong number reaches a lender, a partner or your price list.

## Common confusions

### Source verification vs a citation

A citation is the link the AI gives. Verification is you opening it and finding the claim there.

## Tips

- Open the link and search the page for the exact number.
- Note the date on the source, not just the date you read it.
- Keep a sheet: claim, source, verified yes or no.

## Frequently asked questions

**If the AI gives a citation, do I still need to check it?**

Yes. The citation shows where to look. Verifying means finding the claim on that page yourself.

**How many sources should I check?**

At least the two or three numbers your decision depends on, such as the market size and the competitor prices.
