For a long time a stable position decreased on certain keywords, but suddenly? Very annoying, time to return. The first what you must do case in sun is to come where these sudden are fall to thank. In these blog the most attentive causes.

Onpage: Recent modifications
At a large part of the problems the cause is find on its own site. A small modification is possible already large impact has. Consider you therefore firstly what you have changed in the days for the fall to your site. Can it think of the structure of your sites, classification of menu and left, but also duplicate content.

To give a practice example. Itself I thought nice of adding poll to 1 of my sites. However pale this poll looked by wrongly ensuring much double urls. Result, an enormous quantity duplicate content.

I encountered another error on another site. Someone had introduced a small modification in its layout and thereby accidentally HTML comment opened, but not correctly closed. Result, IE gave ordinary weather to the page, but other browsers had what more problems with the site. The Google bone considered the complete page as html comment and took the contents because of this.

Such as your already are possible onpage see changes large impact have. Frequently sits wrong in a small nook, these find error is then frequently very time-consuming do odd jobs.

Offpage: Risky changes
A fall in the results is possible also do have with factors on other sites. Think you already fast of your link network. These can change by several factors rapidly.

To reflect a practice example. One information sites had been well represented terrible on Wikipedia. On many wiki page risky a direction stood the site. To reduce spam wikipedia decided rest all left from with rel= the nofollow, as a result of which therefore no longer counted left in the search engine results. Result of this modification, the concerning site had suddenly a much smaller link network and decreased very fast in the search result.

Behind offpage changes come is frequently awful difficult. The best option is left in any case the number of using Google Webmaster watch tools. Moreover there are several risky popularity tools. Offpage measure changes are however with difficulty, but certainly worth it watch.

Competition

A fall of yourself in the search result is possible thus to thank be to the increase of another one. There, as it happens, but the one first can occupy place. Especially on popular keyword the competition is violent. You must be reach thus not only busy with a good place, but also with him to preserve.

You watch competition therefore well! Is he extend busy with its link network? There are onpage activity? All factors which you must watch. And do we let be honest, if a someone places link to your competitor, why he then will not prepare its also to you linkje to place?

Technical problems
A another problem can lie at the technique of your site. Is think to the server, but also to the scripting.

To give an example. For a customer I had site have equipped with a vast meter. These kept at when the Google came by bone or a visitor was sent from Google. However by wrong in the scripting a visit of the Google bone to error looked as a result of which the site was not reflected. Result, the site were not well incorporated in Google.

Same type also prevents problems at the server. To a good way see how Google see your site is use of the cache function. You looking to your own site name in Google and click at the results in Cache. Here you can see how Google have found your site. Another appliance are use of Google Webmaster helptools to if see there is crawl errors.

Algorithm changes
A last very annoying factor can be Google themselves. A change in the algorithms of Google can lead to a change in the results. Examples at, such as the recent punishment of paid left.

Changes in the Algorithms are reduce only by here taking into account at the search engine optimization. For this for this reason regularly the several SEO Blogs watch. At large changes also we will give to that certainly attention.

Conclusion
All in all Google are complex. It can cost thus a lot much time to come behind the cause of an oscillation. The solution is sometimes simple, but frequently also time-consuming. Not right moreover expects result to see. Patience is a clean matter.
