I don't think anyone should waste their time on the sandbox - it doesn't exist. A new site of mine was indexed within days. We used to have an old SEO in house and he used to talk about it all the time. Don't want to cause offence! But it's the truth.
The sandbox has nothing to do with indexing. The sandbox applies to rankings on new sites for certain competitive keywords.
I'm sure that the phenomenon of new site doing well and then disappearing from the rankings for a while does exist in some form, although I don't think anyone (except google) can tell you exactly how it works. I've seen it a few times and it certainly happens.
I have experineced this frequently site jums from say SERP 24 to SERP 150+ then some time later it usually comse back to a better SERP This oly happens when we are adding links or doing on page SEO
It does exist especially if your site is new and has just started to get involved in high paying competitive niche.
Well, you are free to think what you want. But no offence here, you are dead wrong... Plus you first need to learn the meaning of sandbox. Indexed within days? Give me a break. I can get a site indexed in 1h but it is completely irrelevant.
Getting indexed has nothing to do with sandbox.. your site will still in google index when it's sandboxed.. they are 2 different thing
If your site is new, mostly your site won't get high rank for the first months even though you have many quality back links. However when the time comes (assuming you are building many backlinks and does your SEO), your site will jump from nothing on the SERP to good rank of SERP.
This thing of ranking in a honeymoon for a while and then suddenly go away as fucking Jimmy Hoffa is somehting that happens to every bloody site that I take online.
Sandbox does exit, Google themselves says so ...check out what google said in regards to the sandbox >http://www.threadwatch.org/node/3479
Well one of my sites, registered in August has just started to appear up the google listings again. This is about three to four months after it went into the 'sandbox'. Does this seem to be a representative length of time or do other peoples experiences differ?
Sandbox is definitely there but applicable more sternly to only a randomly picked set of websites, one of my health related websites got sandboxed for several weeks and others went through smoothly. So all in all you cant ignore the concept. -Citrusweb
