Question

Answer 1

if you put tag like "test", in your question then, if someone search with "test" input then result will be your question ,

Answer 2

Very good question! tags, or relevant tags are words that are relevant, related, or describes your question topic.

Combined together, these tags form a keyword good for searching, for example the related programming language, a subject e.g. array, a certain data type (string, float, int) etc.

Example:
Q: About C++ array
Relevant tags:
c++ array

Q: Read/write file in C++
Relevant tags
c++ i/o read write file

The spaces between words separates the tags, individual tag acts as a link to the search feature using the tag as a keyword.

CONCLUSION:
Tags are very IMPORTANT factor in composing a question, it is what the search feature use as keyword, so everyone need to help, raise the awareness to use tags properly!
