Title must be exactly included in the search query in order to pick up potential traffic?

Question

Search Engine Optimization

I mean that the title or title of the article must exactly be included in the thematic query from the wordstat?

Answer 1

If you meant "should the title include a key from the wordstat", then yes, it must. Title is the most important tag for ranking.
As confirmation of this (as Ankhena already said ), look at the results in search engines for this key.
