Bonjour Archie, 
Sorry about the delay in answering this, but it slipped my mind.
In this example, I think it means -
Me too, I watched this yesterday 
which in French could be 
Moi aussi, j'ai regardé ça hier
BUT If you said 
J'ai regardé ça hier aussi 
You are saying that you watched whatever 'that' stands for and something else.
which I believe in English would be -
Yes, I watched that yesterday too 
But good question!

Bonjour Archie,
I am not sure if you are questioning the place of 'too' (aussi) in English, but you could put it after 'that' or after 'ça' in French.
Hope this helps!

Thank you, Yes I was asking about positioning of "aussi", is it placed after the word it is modifying?
