Just yesterday on google the no of pages indexed by google jumped from 12 to 3040 for my 5 month old site. It has had about 2000 pages on yahoo for the past 5 weeks. However a search for my important keywords which it has indexed is still not showing. Any feed back will be welcomed from anyone that has experienced a similar thing. About two months ago when I was indexed by google a lot of my keywords jumped to first page only to dissappear and as of present no where to be found. Does this means I am out or I am gradually beign released from the sandbox.
