Hi! I have 1 month old site, niche is health. I bought about 10 links and get about 50 do-follow comment blogs backlinks. Im not in 100 keyword, If I write site:mysite I see this site.
You're website is new, and will take a while to recover and show once again in the SERP's Keep on building backlinks and adding quality unique content all the time, then ranking will follow. Might take a while, but we all know SEO is for the long run
You got a one month old website. You couldn't expect it get a higher ranking. Give it some time and keep on building some back links. 50 dofollow back links aren't that much.
What's sandbox ? After it my site is dance in google and get down on position ? How I can get rid of this ?
Sandbox is a filter applied to most new websites, and it's a Google Delaying filter to prevent newly indexed websites from spamming the search engines or retain a high ranking in competitive nor commercial markets based on the targeted keywords / phrases. You wont be able to do anything about, just keep doing the same you've been doing: adding fresh unique content and building backlinks from related websites with higher PR and sooner or later you will start to rank once again.
While Google sandbox is not something you can control, there are certain steps you can take in order to make the sandbox effect less destructive for your new site.for example , Actively gather content and good links - as time passes by, relevant and fresh content and good links will take you to the top hope help
May be you got too many links in very little time, always build links slowly. Hopefully you will get out of sandbox.
The problem is your site is just a month old, new sites can't easily gain such high Google rank. It would take time patience is a virtue my friend, by the way 50 back links is not enough you need many back links as possible in order to get traffic, you can also put interesting articles on your site. People now a days are looking for informative articles, try to post interesting article which s relevant to your site.
the problem is your website is only a month，and it is unstable. it is changing all always. and pay patients to wait and found it is wonderful
"Rome was not built in a day", that is true for SEO. It is important to build links step by step, and update unique content. sure your site will gain high PR in the long run.
