1. The site does not include us through the need to find from their own problems can not be said to be Baidu's problem, the site down the right or not to include the problem in their own this I believe we understand, we go to Baidu Webmaster Tools, find "Web Crawl"-> "crawl Diagnostics" shown in the following figure
2. If the crawl is successful we click "Crawl success" into, here is a site IP address to see if you are not the server IP if we click "Error" can be.
3. If the crawl failure we click "Crawl failure" into, you see there is not resolved to IP or have a robots banned, we click on the back of the IP, small series updated so screenshots can not be word.
Second, grasping frequency
1. Check the crawl frequency normal no, not a few times a day or dozens of times, this look at the station size, if you do not think we can use the "Crawl frequency adjustment"
2. Grasp frequency adjustment as follows drag the slider to adjust.
third, the crawl anomaly ,
1 go in and see if your "website anomaly" is too much straight or directly inaccessible, if yes you need to server load or network for troubleshooting.
