My site has suddenly disappeared in Google result with some of target keywords several days. It have stayed in 1st and 2nd page with those key words for long. I really fear. I'm confused what should I do now. Do you know why is it and how I can get it back?? Some keys that it disappeared: tim viec, viec lam, tuyen dung, tin tuyen dung. My site is nghenghiepviet.com
This happened with my website too, but issue was that i redirected domain to www while it was non www before, so i fixed after 15 days...
I can see your website just fine with site:nghenghiepviet.com so it doesn't look like you're penalized. You've probably just been a victim of an algorithmic update that decided it's time to push your website down the rankings. On a side note, I can't even load your website. Not sure if that's the problem.
The reason behind sudden downfall in your sites Google rank might be due to the recent updates i.e Penguin and Panda. I analyzed your site and would recommend a plugin that will fulfill your all SEO requirements. This rating and reviewing will set a platform where users can post their feedback on the services you offer.
