Analysis of the reasons for declining rankings of Google

Google began to drop the time from the day before yesterday, when the day before the discovery of the number is 454, compared to the previous 476 less than 22, the key word e-Bole ranked by the original first fell to 12, yesterday when the number of times recorded fell 300, The key word e quotient Bole ranking in the 100th, this morning when the Google included has dropped to 248, why Ah, Google down the right, the site was K. But Google spiders every day to crawl my site Ah, snapshots are the latest, and the site in other search engine tutorials are normal, Baidu's snapshots are updated every day, the number is also steadily rising, there is the Alexa rankings are also rising AH.

So from their own website to find reasons, carefully think about the site to do some small changes, analysis of the reasons may have three:

One, the original article less. This also does not calculate to do the alteration, is the website article most is duplicates other website, but the article copy comes when all is the newest publication, some has made the slight modification, some did not have; in the previous Google's collection is still increasing, no problem ah? Why has it been reduced this time? Is Google in the big clean-up, do not know, the original article is less likely to be included in the decline of one of the reasons. In short, the site content or a little more original good, whether it is true original or false original, as long as the search engines do not recognize, is original.

Second, the style changes. I added a display:none to a label on the website page; The search engine is more sensitive to it and thinks it is cheating in SEO. I just think from my point of view there is no need for it to show and, but it has brought serious consequences. In fact, there are three kinds of hidden code methods through CSS Tutorial: 1, CSS code display:none;2, Visibility:hidden visibility hidden; 3, overflow:hidden settings; Here's a reminder to pay attention when you use it, It's best to put them in a separate style file or otherwise instead, to reduce the potential negative effects on the site.

Three, 51 statistics "noscript" script. We all know that the noscript element is used to define alternative content (text) when the script is not executed. This label can be used for browsers that recognize script tags but cannot support scripts in them. This means that if the browser supports scripting, it does not display the text in the NoScript element. E Shangberla site Just add 51 statistics code, Google K, this we can from Google and Baidu snapshot in the look out.

Google's snapshot source code is this:

　　

Baidu's snapshot source code is this:

　　

By contrast, found that Baidu is not read JavaScript code, "script language=" javascript tutorial "type=" Text/javascript "src=" http://js.users.51.la/ 3569397.js ""/script "the code did not appear in the Baidu snapshot, and Google can understand, so the" NoScript "may be Google rated as SEO cheating, so do SEO friends to consider clearly, Baidu is required to do SEO or for Google to do SEO.

These are the changes that my site has made before Google K, in this admonition, do not repeat the same; Of course, Google included e quotient of the number of bole and the decline in the keyword ranking may be caused by other reasons, here I said may not be all right, I hope the master can help to look at, analysis, To explore the reason is out there. The above Display:none and JS script problems I have corrected over, I believe that Google will be able to recognize my site again.
