Thanks for all of your replies. I did have a Google Webmaster account, but it was very strange when I checked the Google Webmaster account I saw it required me to verify my website address again. I don’t know why the Google Webmaster account suddenly lost connection to my website. Such thing has never happened before. Anyway I verified it.
Now where should I identify the problem in my Google Webmaster account?
I added alexa affliate to my site 6-7 days ago, but only 6 pages, will that cause any problem?
Thanks.
