# Message match check

An ad makes promises: a price, a trial, a guarantee, a deadline, a deliverable, a feature.
A visitor clicks because of one of them.
This skill reads the ad, fetches the landing page, and checks each promise against the page text.
Every verdict comes with the page words that back it.

## Inputs

You need two things.
If one is missing, ask for it before you start.

1. The ad text, word for word: headline, description, and any extension or caption.
2. The URL of the landing page that the ad sends people to.

## Steps

### 1. Fetch the page

Fetch the landing page at the given URL and keep only the visible text: headings, paragraphs, lists, tables, buttons, and labels.
Ignore the meta description, the `og:` fields, scripts, and the ad itself.
They are not page text.

If the fetch fails, the page shows a login wall or a bot check, or the visible text is under about 50 words, stop.
Say what you saw, give every promise the verdict `Not checked`, and go to step 5.

### 2. List the promises in the ad

Read the ad as a visitor does and write down each checkable promise.
A promise is checkable when the page can state it or conflict with it: a price, a billing period, a trial or its length, a free tier, a guarantee, a deadline or turnaround, a named deliverable, a feature, a quantity, or a condition such as no fee.
Skip the brand name, slogans, opinions, and words with no specific content.
Quote the ad words for each promise exactly as the ad states them.

### 3. Find the page text for each promise

For each promise, search the page text for the words that address it.
Quote the page text word for word.
Never paraphrase a quote, and never quote from the ad.
Prefer the line nearest the main heading or the main button, and note when the only match sits in a footer, a footnote, or an FAQ at the bottom.

### 4. Give each promise one verdict

Use these verdict words and no others.

| Verdict | Use it when |
| --- | --- |
| Kept | The page states this promise, and the quote shows where. |
| Partly kept | The page states part of this promise, not all of it. |
| Contradicted | The page says something that conflicts with this promise. |
| Not on the page | We did not find this promise anywhere on the captured page. |
| Not checked | We could not check this promise, so it has no verdict. |

Rules for the verdict:

- A promise is `Contradicted` only when you can quote page text that states a fact that makes the promise false: a higher price, a shorter term, a stricter condition, a fee the ad denies, or a statement that the offer does not exist. Never call a promise contradicted without that quote.
- A page that offers as much as the promise or more does not conflict with it. A 60-day guarantee keeps a 30-day guarantee.
- A number about a different thing does not conflict with the promise.
- A page that states the promise in a weaker, vaguer, or narrower form is `Partly kept`, not `Contradicted`.
- A page that gives no proof for a promise does not conflict with it.
- A heading, category, list item, button, or product name that names the promise supports it.
- When the page text is complete and never addresses the promise, the verdict is `Not on the page`.
- When the page text does not settle the promise, the verdict is `Not checked`. This covers a page you could not read in full, text that depends on a script or a form you cannot run, and ad words too vague to compare.
- Judge only what the page says. Do not judge whether the promise is true in the world.

### 5. Write the report

Use this format.
Keep the quotes word for word.
Give one line of explanation per promise, and name the fix for a promise that is not `Kept`.

```
Message match: <landing page URL>
Ad: "<ad text>"

Promise 1: "<ad words>"
Verdict: <verdict>
Page text: "<quoted page text>" or none
Note: <one sentence: why this verdict, and the fix if the page needs one>

Promise 2: ...

Kept <n> of <total> checkable promises.
```

End the report with this line, unchanged:
