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.
