Why would sitelinks disappear

[GeorgeLaRochelle]

For over the past month my site has received sitelinks from Google and they have been really helping out. All of a sudden this morning they are gone. We 301'ed and redirected (WBT) another one of our other sites to this one on monday. Could it be Google is just trying to figure out what we are doing? Has anyone else seen sitelinks come and go on their site without any other redirects?

I am assuming it is because of my sites combining but wanted to hear if anyone else saw sitelinks come and go on their own.

Thanks

They did come back after a couple days, I sure wish they would make up their minds. Thanks again for the responses.

Sitelinks are a sign of domain authority in googles eyes, I dont mean it's like a huge thing, but google trusts your site enough to show more links and that's a good thing.

I have seen them come and go just by switching browsers, I.E shows them mozilla doesn't and vice versa, also if you have made a lot of changes recently it could be a case as you say of google trying to figure out when you will stabalize and then rank you/trust you accordingly.

Unless someone there is fiddling with the settings in Webmaster Tools for sitelinks I would chalk it up to Google constantly tweaking how things are displayed on the SERPs. It could even be a matter of what Google server you are hitting (one may show sitelinks and another may not).
