Why did my site traffic suddenly drop?

[Max]

google is always updating it's algorithms to try to remove copied content, spam content and spammy backlinks.
Whether you know it or not you may have been recieving success from google through thousands of spammy links, and google may have only just classed them now as spam.

Many seo companies will create 100,000++++ backlinks from where ever, who ever and how ever they can, so if you have used a seo company this may have been what happened. These seo companies can boost you to the top of search engines, but once they stop your site will drop like a bomb.

Or maybe you have just copied and pasted alot of content from other sites without changing anything and now google has de-indexed your site.

Try writting your content to make it uniques, add unique title tags for your pics....


Take the time to go back through your site rechecking all your on-page and off-page seo

Also take a look at google webmaster tools, alot of time they will notify webmasters if they have been majorly de-indexed
