I look for keywords regarding the tools I use and that describe myself. For me, it's C, C++, random Javascript libraries, databases, certain computer hardware, companies I use, and certain startup business terms. It can be a keyword soup that doesn't make sense and I'll still click on it. I also click on words that appear to be made up, because I've been trained that I'll usually get to read about a cool new library, programming language, or programming tool. In your example, "quantum" is too vague. Even though I've worked for years in quantum-whatever areas, I feel that the word "quantum" doesn't describe myself due to being too general, so it doesn't trigger my attention. So basically, I just scan the front page for words that are attractive to me, never fully reading headlines until I've already decided I'll click on it.
