Dear all, i have a doubt about Google indexing and crawling rate. i want to know that what is time period of crawler when he come to indexing on my website . please answer me that..what is actual time for Google crawl and how many days after crawler returns to my website.
It depends on your site and amount of data in kilobytes it needs to fetch from your site.If you look at Google webmaster Tool you can find many answers that you have added here. No exact time.Time of crawling and indexing depends on what you have on your site(kinobyte data) and how much content you have on it.
Google has evolved greatly since last year or two. It crawls a site nearly instantly when a new content is added to it. But indexing is something that one cannot be too sure of, pretty hard to tell.
You can have an idea about your sites crawl rate by visiting, Google WebMaters Tool > Health > Crawl Stats.
The time is unknown ! really, only google knows it, You can try to ping Your website to google by using google webmaster tool.
