Welcome to the Q&A Forum

My domain's homepage has been ranking 1st position for an specific term for about 8 months. Our domain got hacked and it took just one day to make the website right again. A week after our homepage didn't appear anymore in Google results, it isn't even indexed. However the rest of our internal pages keep being indexed and ranking as usual. How can I make my homepage appear again in the results? Is there a way to speed up this process? Will it be in the same position as before, or will it have some sort of penalization for the hacking?
