Are there any shortcuts in SEO? Does it really need to take more than 3 months to get out of Google sandbox for new domains? Still there are a lot people arguing if there is a Sandbox. The answer would depend on the definition of what 'sandbox' means. If a 'sandbox' means the un-favorable situation which a new website would rank for competitive keywords, then 'sandbox' really exists.
In my SEO experience, a new website would not rank very well in its first level keywords. How does Google decide what are the first level keywords in a website? Google has a very smart calculation for this. If the keyword phrases are in your title tap, and also in your headline or even in your bold text, you are almost guaranteed Google would find out what your first level keyword phrases are. If you have some valuable links, you would probably rank well in your second level keyword phrases, but not the keywords you most desire. About half month after your first PageRank update, your ranking of your first level keyword phrases would gradually increase. And about another half month, the true value of your ranking positions in all keyword phrases would show. This process would take about 4 months in total. That's right! 3 month to wait for the first PageRank update, another month for graduate rankings increase.
That comes to the question-is there any shortcut to the sandbox situation? Yes, many people have tried, and it works. Go to some auction sites and buy an old domain name, the older the better. You have to be very careful that this old domain you are buying is not a banned site. If the domain has a PageRank which would be safe to buy. If the content of this old domain was doing something near your new website topic would be even better. Then, you 301 redirect the old website to your new website. About 3 weeks later, you are ranking as if you are a trusted old website. If you wonder how to do the 301 redirect, you can search for '301 redirect code', people teach you all that.
3 weeks compare to 4 months in the Sandbox is an amazing deal. If you are still thinking 3 weeks is a little too long, then you may build your website directly in this old domain. The disadvantage is that the old domain name may not be your favor. And the existing backlinks of this old domain may somehow look strange to Google because of the un-relevant contents and anchor text of the link page. You may be thinking-is it that same if I '301 redirect' the old domain to your new website? The backlinks of the old domain is still not relevant. Would it harm my new website? No, because the action of '301 redirect' is made in the old domain. Your new website does not need to do anything with this action. Remember Google in its official page saying that never hurts you!
If you still worry, you might think in this way: imagine if there is a competitor who would like to pull you down from the ranking, then your competitor '301 redirect' a web page with illegal content to your website. Do you think you would really be pull down? If this '301 redirect' would anyhow harm you, a lot of sites would not exist in this moment. '301 redirect' should not harm you anyhow.
