By default, Microsoft Bing sets its own crawl rates and times based on load sensed from your server.
If you are experiencing bandwidth related server load issues (i.e. too many requests too quickly), you may want to reduce how fast Bing and other search engines crawl your site. Too many requests on your site in a very short period can cause your site to load slowly and even cause load issues on the server. This is especially true of very busy websites, or websites that are poorly or inefficiently coded.
If you are not experiencing any bandwidth or bandwidth related load issues on your server, it is recommended that you allow Bing to determine the optimal crawl rate for your website.
Changing Bing's Crawl Settings
Microsoft allows you to set the crawl rate for your site, and even allows you to specify the crawl rate by hour of the day (a crawl pattern). This allows you to specify that Bing crawl your site more aggressively during non-peak hours, and less aggressively while a majority of your visitors are online.
Before specifying a crawl pattern, you may want to view your web statistics in cPanel to see when most of your visitors are online.
To change Bing's crawl settings:
- Login to Bing Webmaster Tools
- Add your site to Bing Webmaster Tools, if you have not done so already.
- Click on the Crawl tab in the top navigation.
- Click on Crawl Settings in the left navigation.
- Select your website from the drop down list, if not already selected.
- Select the radio button "Use the selected crawl rate below" to set a custom crawl rate and pattern.
- Use the graph to specify the crawl rate and crawl pattern by dragging the graph areas to the desired settings. You can click on individual vertical columns to set the crawl rate individually by hour.
- If your website is built in AJAX, select the check box labeled "Configure Bing for Ajax site crawling" so that BIng handles your website properly.
- Click the Save button to save your settings.
