Manual or Algorithmic Penalty Rank Drop
This is usually a big drop in search engine rankings, that happens over-night. If you notice that your site drops more than 10-20 positions on a multitude of keywords, this could specify a penalty. A big difference between algorithmic and manual penalties is that the first ones are automatic and are usually released with different Google Updates, while the second ones are manually applied by a Google employee. Given the fact that Google made a habit out of making updates without clearly stating it, you should regularly monitor for ranking changes. You know you have been penalized by Google if the drop is harsh and swift, and you can see that your site continues to rank on other search engines like Bing or Yahoo.
You Got OutRanked by a Competitor
This is usually a slight drop in ranking. You will see your competitor’s site that outranked you and the other sites will always be in the same positions as before. You should constantly monitor and analyze your competitor’s sites and social profiles to better understand what they are doing. Tracking your main competitors and understanding their link building strategies could anticipate their next moves.
Your Site was Demoted due to On-page Issues
This is either a big drop or your site can not increase in rankings. It may be a sign of concern when your rankings start to slowly fall behind other sites, even though you are seriously trying your correct to create content and building links.
Maybe you get a lot of broken links or a bad internal linking. Use the HTML Improvements feature to perceive any problems with tags. “Abuse” the PageSpeed Insights as it gives you correct information on what problem you may have with your site and how to fix them. Or maybe your site got hacked. All of these can be found in Google Webmaster Tools. Always track your site in GWT and GWT notifications enabled and sent to your email address. If you do this, the chances of being a victim of on-page issues will decrease.
Your Site Dropped Because it is Losing Links
This is either a slight or big drop. You will see massive spikes in link velocity, as you will have a lot of inbound links disappearing from your link profile. If you see a lot of lost links this might specify the ranking drop. Check those links individually. If those links were intentionally removed by webmasters this might be a red flag to Google that those were unnatural links. I can not advise you here to ask them back, as Google may penalize you in the future. This drop might have happened faster or later without those webmasters dropping those links.
Google Just Updated Their Algorithm
This is either a slight or a big drop. You might be scratched a little or you might be in serious difficulty. In either case, you might suspect an update if you are rankings are suddenly and rapidly dropping.
Check the SEO news sites for news related to a possible update in that timeframe. After this is clear apply those findings to your own site.
