What Raises the Score, What Lowers It
It is by what mathematical rules the score, starting from the base score, changes according to the qualities of the news (headline, authority, quality).
The score starts with a base score of 60. If the news is a headline it receives +10 points, if it is not a headline it receives minus points according to its scan order (order×2). The news being covered in a large number of sources brings a +(8 × authority) contribution, while being a low-quality item (for example, clickbait) brings a -25 penalty point.
Example: The score of a news item that is a headline (+10) but is labeled low quality (-25) dropping from 60 to 45.

The scoring system is not a secret algorithm, but an open mechanism whose rules are clear from the start. Trending words contribute directly to the score (at most 3 words); a newly exploded trending word brings a +7 bonus, while an older trending word brings +4 or +2. Thus, the upper limit of the trend bonus is roughly around +21 points. However, items with only similarities get a +(3 × authority) contribution or those that have very few sources and benefit from equal opportunity (+8) also increase their scores.
