Type link:www.mysite.com in Google search,I found my site have 10 backlinks from other sites. Since that, I found those keywords drop to 300... I don't know What happened. Anyone can give me an answer?
How many backlinks had you prior to the update? Have you checked your backlinks on other search engines. Also do a check to see if links to your site are still there. If you give out your sites URL, there are many knowledgeable people in the forum who might be able to help you out.
I understand google sandbox can be any length, and it is unknown why a site is sandboxed or what determines the length of time. It’s best to develop other traffic sources also.
