Can I resubmit a webpage to Google after I make changes?

• After making important changes to a webpage on my site, I'm wondering if I can resubmit to Google for reindexing.

  What are your thoughts? Would it speed up the process of getting reindexed by doing so?

Answer:

Maybe. However according to Google's John Mueller in a recent Reddit post, you don't have to because...

Google refreshes the index of the pages it knows over time automatically, you don't need to do anything to make that happen. If it's urgent, you can submit it for reindexing, but that's extremely rare across the web.

So, in urgent cases, you can resubmit your page(s) by following the guidelines you'll find here — but normally you don't have to do anything because Google reindexes pages they already know about without any special help.
