How to make checkbox selection less of an eyesore?

I'm working on a component (see image) that shows the results of a keyword search.

Each result displays:

• the title/link to an article,
• a snippet from the article,
• a checkbox reading "This article solved my issue" that the user can select if the article actually did solve their issue.

A majority of users I asked feedback from said they glanced over or didn't notice the checkbox because it visually blended in with the text above it; they weren't compelled enough to select it.

Is there a way I can visually improve the checkbox, such as a design pattern that may help fix this? I want it to be noticeable, visually pleasant, but not outshine the article title and snippet.
