I am reciving around 1k users a day from google/yahoo ... now, if I will set a domain name parking service for 1-3 days, will i get dropp down in google/yahoo or even have my whole website excluded?!
For 1-3 days I don't think it will matter unless the bots visit during that time. Why would you want to do this for such a short time?
Nothuing but they aren't very hoinest people, I mean they ask you to park your domain name for 1 month ... to them. They won't pay 1 cent to you that mounth, and after 1 month they will make a 6 months contract with you ... lame...
If you really want to park it there are a lot of reputable parking companies out there to choose from.
