Hi- Why suddenly ranking down in search engine?....please suggest best solution with causes thanks.

- New Links
- Lost links
- Dropped redirections
- Algorithmic penalties
- Algorithm changes
- Check the technical fundamental
- Changes to the site
- Server issues
- Changes in search behavior

Lost links and Plagiarism content affects ranking very much.

I think there were some changes made in the google algo that made some sites change there ranking.

If you see an abrupt and significant drop in your website rankings, it could indicate that Google is penalizing your site. ... If your site continues to rank on other search engines like Yahoo or Bing, this is an almost sure sign that you are suffering from a Google penalty.
