On Stack Overflow? A good question contains a reproducible problem (or at least an understandable question) and it's worded such that people with the same problem will find the question and answer by googling.

Better than that is better, but that's the threshold between bad and good.

So include error messages instead of just typing "I got a certificate error when …", because people who get the same error will paste their error message into google. Some of then paste it into bing. None type "I got a certificate error when …" into google.

Stack Overflow is about building a knowledge base where people find answers. SEO is essential to that.
