Is it common for a new site to get indexed, deindexed and indexed again?

Is it common for a new site to get indexed, deindexed and indexed again?
I had a site that was indexed but now it is not showing up on google anymore. Should I be worried or will it be reindexed again?

 

yup, it's called Google sandbox. New sites get listed in Google right away (in their sandbox), and then once it is established it goes back down.

Not sure why this happens (maybe to let new sites get feedback).

Or you could have done some blackhat stuff and were flagged (ie. keyword stuffing, hidden keywords, page hiding)

 

I am not using any blackhat seo

 

I am not really familiar with being sanboxed.. but I usually encounters this term, but now its clear to me..
Thanks for the explanation..

 

I thought the sandbox was when your site loses rankings, not when it gets deindexed. Am i wrong?

 

It's happen to me too. I was lost more link that was indexed last week.. any solution?

 

wait crawler will take sometime to index your blog permanently

don't add too many keywords and try to add some less keywords articles

 

I think you should use another tools for checking to Google index page.

 

The Google Sandbox acts as a probation for new sites, probably to discourage spam sites from rising quickly, getting banned, and repeating the process.Thus the Google Sandbox is very similar to a new website being placed on probation whose rank is kept lower than expected in searches, prior to being given full value for its inbound links and content.

 

You say the site ranks lower during sandbox but does it get deindexed during sandbox?
