The dictionary describes "one-off" as:
done, made, or happening only once and not repeated.
I am using this word in the the following context:
Two types of solutions are gathered to improve the website:
- One-off improvements that can be implemented while developing a new version of the website.
- Content guidelines that help users to write higher quality content. These guidelines make it possible to raise the quality standard in the long term.
I am not a native speaker, but "one-off" looks a bit.. off to me in this context. Am I wrong and is this correct, or should I replace it with a different word?
