Just want to confirm!

after editing the page in how many days the google index the page?

There’s no rule. Google visits when it wants to. Some popular sites it visits throughout the day, while other sites there may be weeks between visits.

Yes there is no rule but if you add this meta tags “<meta name=“revisit-after” content=“7 days” />”, i think this meta tags are useful for you.

Thanks guys,
Your answer means a lot.

The easiest way to get Google to immediately index a page is to post an update about it in your Google+ account. “Just thought I’d let you know that we added a new widget to {page link}” or “Great News! We just added a great new Q&A feature to {page link}.”

Things posted to Google+ get indexed practically immediately!

It is not mentioned in any rules that the specific time will take to get page indexed. But according to me it will take 3 days to index your page.

Your site will get noticed by search engine in 1 weeks time.
