How do you tell if Google has sandboxed you? In the beginning i was getting a decent amount of traffic. My site is about 1 month old, for the last week its been getting 0 views.
Usually your domain still appears in google index but search engine search for certain competitive keywords does not yield your site among the search list even though you are having strong inbound links and have fully optimized your site. Most of the time, your site can only be found on some secondary or unimportant keyword searches.
