no, and that is a sign of sandboxing or banning, if you type in your domain name does your site link show? if so then you're site is not banned, maybe sandboxed.
Yeah it looks like you've got sandoxed, never mind you might get out again in a few weeks so keep on seoing
Just found some articles... wow that sucks. I'm not spamming, why the heck would they sandbox me? My domain was created 06-may-2009 and doesn't expire till 06-may-2015.
How are you sure I am sandboxed? When I do a site search all of my pages are indexed... my sitelinks are just gone. 2 of the sitelinks they had have changed... I wonder if that spooked it?
my rankings also appear to be the same as well as traffic... what gives? i did notice that if while you are logged in and you do a search you can vote the relevancy of your links. is that new?
I used to have site links, but they were lousy, and only narrowly representative of my site. So I reorganized my navigation, to get Google to give me better, more logical site links. Ever since, I have had NO site links whatsoever, even though picking them now should be a no-brainer. No sandbox for me, since the site is 6 years old. Ha-ha-ha-ha-ha ... ha . . . . . Boo-hoo-hoo-hoo-hoooo . . . Waaaaaaaaaa. Screw it. Traffic is growing. . .
Yes I think there has been some issues with the Google backend lately. My site links as well as my traffic has reduced since last one month. I guess they are revamping their entire algorithm and as everyone knows that the PR update is due by the end of this month. I guess they will be rectifying it all at once alongwith the PR update.
One of my site has sitelinks disappeared and then re-appeared for a few days later. This could not be always a sign of banning or sandboxed. This can be apply in case you did not change total site nativagation too sudden.
