I am actually confuse that some SEO people says that sandbox is available and some says sandbox is not available...........I want to know what is truth..........Do you have any idea???????????
I have an idea. Sandbox exists and i have experienced it. Try it yourself if you are not sure whom to trust.
Some terms/phrases experience it. Some do not. Whatever google perceives to be "competitive" - whether it actually is or not - can get tossed into the sandbox. Only way to see if your niche has it, is to try it for yourself.
it does exist. Google seems to give a short term boost to 'fresh' stuff. Which wears off pretty fast, then you have to slog up the hill like everyone else.
