For the past month, my site's google indexing number suffering a drop from 1800 to 1250. I used site: search operator to check this, and the outcome number seems like dropping everyday, it's like a trend, that why I take it very serious.
I upload the sitemap in WMT, but it doesnt work. Why there is a declining, and how can I get rid of it? I need help, thanks in advance:)
