Rob Sullivan over at the TextLinkBrokers.com blog has somehow found a link between AdSense and escaping the Sandbox.
…I have another site that I started over a year ago, and have been dutifully building content and links, yet I can’t get it out of the sandbox. In fact, the current Google cache is of pages that no longer exist, and haven’t for months.
My explanation, however out there it seems to be is that somehow the Google Ads have allowed the site to bypass the sandbox and move into the index almost immediately.
The first Google organic referral came last week, just two short weeks after the site was tagged with the Google Adsense code. Since then, both sites have received a handful of Google organic referrals.
Based on this very small and somewhat limited test case, my gut is telling me that one way out of the sandbox and into the SERPs is to apply for and install Google AdSense onto your site.
I’m not convinced. Some of his examples are circumstantial at best. Definitely not something I’d stake my site’s SEO on. The good thing about it is, I’m so not convinced I’ve decided to do a scientific study on his hypothesis myself. Stay tuned for more details.
