Adjusting Crawl Rate Through Webmaster Tool

[kabirthapar]

I wanted to know whether changing the crawl rate in Google's Webmaster Tools really made a difference? Does Adjusting the crawl rate has any effect on ranking? Kindly help

To limit the crawl rate:
1. On the Search Console Home page, click the site that you want.
2. Click the gear icon , then click Site Settings.
3. In the Crawl rate section, select the option you want and then limit the crawl rate as desired.

The new crawl rate will be valid for 90 days.
