Title is the summary.

The title sometimes is used as a summary of what you will be talking in the essay. Therefore, I think, good title first has to match with the content of the essay, for instance, If you write about summer, the title should be "summer", not " winter". It can be also be use as part of the thesis. The title is usually short but it is necessary to make it understandable and make sense so reader can have some ideas of what you will talk about and decide if they want to read it or not. Secondly, a good title shouldn't be too broad. The more specific and clear the title is, the easier it will caught readers' interests and attention.
