How Indexing rate and Crawl frequency affect your website?

If we want to describe crawl rate in simple words then, it is the rate by which the Crawlers (bots) encounter the URL of your website while crawling millions of other websites across the web. Obviously, two factors will surely be there, Quality and Quantity of website on which our link has been found by the Crawlers.

If Quantity of links being found by the Crawlers is more then it will help increasing the crawling rate of the website. At the other side, if our link is found more often on very Good Quality clean site which got really useful web content, then re-indexing of website is been considered. It is but natural that a Good quality site must be having a really good indexing frequency. Let’s say Wikipedia.org & Mashable.com

It has been analyzed that the following sequence actually works in achieving good website visitors:

Case 1: Quality + Quantity Links -> Good Indexing + Good Crawling Frequency
Case 2: Quantity + Quantity Links -> Good Crawling Frequency
