Is my site still in Sandbox mode?

I started one of my sites in the first week of this year. We got a lot a weekly fresh new content. After 2 months we got 250 visitors a day and then we where not in Google anymore. So I assume that we where in the Sandbox, we where back in June after 3,5 months.

After then the website is a few days good in Google and we got 100 visitors a day, and sometimes the site can't be found for a few days. This process is going since half of June. Is this still the Sandbox effect?

Your site is probably just dancing... This is normal, be patient... Could last for few days to few weeks then it should settle in.

Thanks JohnnyRabbit. Because we get not really motivated because of the "dancing" you call it. But now I know it is normal and we just have to wait!

If you type site:http://www.mysite.com and it's indexed by google and you can't see your site anywhere, than yes that mean your site is sandboxed for some reason.

I think google take o to 6 month to release a site from the sandbox. You just keep doing link building try to take links from the higher pr sites it will help you to come out of the sandbox fast.
