For your question to be on topic, it has to meet some requirements. Fulfilling these is not only easy in most cases but also likely to improve question and answers:
Indicate prior research effort
Before asking, consult some dictionaries or similar resources. The benefits of this are twofold:
Replacing a dictionary is something that we cannot and do not want to do. Questions that can be answered by a dictionary are off-topic here as they do not concern the finer points of the language (also, those questions are already answered).
If the answers obtained from a dictionary fail to satisfy you, explaining why is very likely to clarify and improve your question (see below).
Ask a question of general interest
Do not directly ask for a translation of the specific sentence you are struggling with (or assume a highly specific context otherwise). While there is nothing wrong with using your specific problem as an example, your question should be asked such that answers to it are useful to others. You can ensure this in the following ways:
There usually is one word (or phrase) which you fail to translate or where you fail to decide between translations. Your question should be about this word and not a whole sentence.
Try to boil down your example by removing parts of the sentence that do not matter for your problem. Maybe what remains is already a frequently used phrase and thus of general interest. However, think twice before relying on the boilt-down example only, lest your question becomes unclear or too broad.
Find other example sentences.
That being said, some sentences are used so frequently or prominently that their translation is of general interest.
Explain and clarify
As for every question, the more information you provide, the more likely is your question to be understood and the more helpful will answers be for you. You should consider in particular:
Provide some example context.
If you are asking for the translation of a word or phrase, make sure that it is clear and disambiguous. If necessary, define or paraphrase it. After all, we can only translate what we know. This particularly holds if dictionaries do not contain the word and if the translation is not between German and English.
If asking for differences, try to explain why you think that the meanings of two words or phrases overlap in the first place.
