Is it advisable to publish a paper with the same name as your thesis? I am about to submit my MSc thesis which is written in the shape of a paper manuscript plus introduction, extended conclusions and the appendix. My research group encourages this format to streamline the publication of research results. I now have to chose an appropriate title for both the paper manuscript and the thesis itself.

Would it be ill-advised to choose the same titles here? On the one hand both works deal with exactly the same topic and I initially put the same titles, on the other hand it might be weird to end up with two publications of the same name once the paper gets published somewhere (considering search engines etc). This whole format is fairly new to me (and my supervisor) so I am interested in opinions and experiences from the community.
I agree with Buffy that this is a bit tricky. One could argue that using two different titles (or even two different texts sharing the same thoughts) for two documents with practically the same content is an effort to give the impression that you want two "publications" for one. For this aspect, the title or the text themselves are not so important, but the ideas are. In this sense, all thesises with results published in a paper share the problem with you. But I do not recall that this was ever discussed as problematic, so I see no fundamental problem here. But the discussion here already shows that there are different opinions.

In my experience, it is extremely rare that an MSc thesis is good enough for me to publish as it is. I usually have to improve the discussion a lot to be completely happy. So you can be proud of yourself if your advisors will pass your text including the exact same title to peer-review. Have they said that they will do so without major editing?

Self plagiarism might be an issue, if your university has a policy on that, but I have not yet really understood why this term exists at all. However, you should check the copyright situation in general with the journal you select. Many journals allow to use the contents of the paper for thesises and the like, but you might have to ask for permission. Or you could go for open access. 

By the way: I know many people who change titles for instance when they present the same results at different conferences, just to make it look better on the publication list. I would not call this good practice. Buffy hits a point when encouraging you to make things transparent.
