Hi After reading so much about google sandbox effect for years now. I have found that its simply based on what keywords you are targetting. In these years for reading, I have also read that yahoo and msn might start their own sandbox filter. Although its scary but it can be true. At least in yahoo case. The way I see it, Yahoo was using google search engine and they have been coping google since the day they started their own search engine. So, I wouldn't be surprised to see a Yahoo Sandbox Effect in the near future !
MSN... I still see new sites get listed there and manage to get good rankings for their targeted keywords. Yahoo... Im sure we will see a big update soon.
MSN certainly does not, unless it's less than a week. Yahoo may do, but again it's possible to get well ranked within a couple of months.
no msn dont have sandbox because news sites can be on top but not sure about yahoo, i hope it not strat sandbox
