As others have said, maybe, maybe not.
In my vertical, if "Macy's coupons" is the keyword, then everyone in the field puts that first in the title tag because the conventional wisdom is that it's the optimal placement.
The problem with that strategy is that everyone's title tags are nearly indistinguishable from one another. Literally nothing in the column stands out from anything else. Blah.
When we added a dynamic count to our titles, eg. "7 Macy's Coupons", and wrote them so they remained keyword rich while also reading more naturally, we observed two important things:
1. Our rankings did not change at all.
2. CTR went up.
The working hypothesis is that the number helps us stand out and the natural structure is easier to read and digest. It's optimized for human eyeballs just as much as it's optimized for ranking.
That's just one example, of course, and I'm sure others can line up with examples where the slightest change to a title tag knocked them back to page 30. I'd recommend testing it out.
