how do I count the number of times text in column A matches text i

I'm trying to count the number of times text in one column, say, A matches
text in another column, say, B. So, if A1=B1, count = 1, then if A2=B2,
count = 2, for the whole of both columns.

You can use:
{=SUM(IF(A1:A3=B1:B3,1,0))}

This is an array formula, so don't type in the {}, use Ctrl+Sift+Enter to
confirm(not just enter) the formula.

=sumproduct(--(A1:A100=B1:B100))
