Are you saying that they went to the page and, without actually reading the text, determined immediately that it was a thin page just by gauging the amount of text on the page, and then left without reading it?
Or do you mean that there were only a few lines on the page in the first place, so when they "scrolled down a few lines" they had finished reading all the content?
It means that when people google "what does 'my hovercraft is full of eels' mean" they're looking for a page that says at the very top, in 36-point type, "It means 'please give me a box of matches'." If it isn't there, they leave without ever reading your masterful treatise on new fishing techniques.
... And if it is there, the sentence will be right on the SERP and they'll never go to your page at all. There is a moral in here somewhere.
It means that the relationship between what google thinks is the best match for a given search string, and what people really want when entering the said search, is ... umm ... unpredictable. So the problem may not be in your page at all. Unless you want to take the effort to sabotage your own search results so people looking for information on X don't blunder onto your page just because you've got a series of words that looks promising to the computer.
