I have registered a new domain 20 days ago and I started building links and seeing traffic, by today ( after 20 days from registration date) I am out of google serps except for typing the exact domain name in search I have checked the yahoo back links it says I have 600+ links (but mostly from same couple domains i.e sitewide) do you think I was too fast in linking and what will happen next??
it is usual for new domains. just keep building links at the same rate as you have been till now and your site will come back up soon
Just do what you did, google bots indexed slower nowadays specially with fresh domains, i've experienced it also 3 months ago ..
