Google stores all of your search history

Google goes for all users "personalized search" mode, even if users are not logged. Thus the search giant hopes that people presented with better results. Previously, the personalized search only logged in users offered, and only if the "Web History" had turned in their Google Account. The new measure, everyone gets customized search results based on search queries and results of the last 180 days, in an anonymous cookie in the browser are stored.

According to Google the information is entirely separate from the Google Account and the Web History feature. Users will custom results based on a "View Customization" link on the search could identify. By clicking the link becomes clear how the results have been adjusted. This also makes it possible to link it to turn off personalized search

Removing information from Google?

Let me start with the good news: you can control what content of your website in the search index is included.

As a website owner you can be in the robots.txt file or Robots Meta tags which information from your website you do NOT want indexed by search engines.

It happens sometimes that information is already indexed before you've excluded from indexing by example robots.txt file. But how do you get that information off the search engines?

Let's look closely at the potential for Google to remove information.

     Tip: For more background and information on the manual "How does a search engine?".

Active vs.. passive removal

You can for a particular page of your site simply delete the page but Google does sometimes months in its cache for the index is stored.

It is possible for information to refrain from indexing by Google, both passive - using robots.txt or robots meta tags - and active - Google Webmaster Tools (only your own sites) or a removal request to Google for information from other sites (both require a Google Account).
Google Webmaster Tools

Google Webmaster Central, Google offers a variety of tools that enables webmasters to make extensive use of and insight into the way of indexing by Google. Google Webmaster Tools can only be used on your website (s).

In this Google Webmaster Tools it is possible possible to operate individual URLs (web pages, images or other files), folders and subfolders, your entire website or the stored copy (cache) version of the Google search results easily Google to remove.
Which method should I use why?

As said, you have several options, both passive and active, to remove information from the search engines. The following chart, prepared by Danny Sullivan (source), gives good weather which method is suitable for any purpose, including the tool from Yahoo (Yahoo Site Explorer) is included.


Stop Crawling: If 'Yes', this will stop the search engine to crawl everything is excluded. 'No' means that the page may be "read" by the crawler, but NOT in the index.
That does not mean that URL does not appear in search results! See "Link Only" recording for more information.
Stop Recording Index: the URLs that are excluded are not stored in the index of search engines. Again, the URL in the search results.
Stop Link Only 'Shooting: In this case a page is not indexed, but Google has the URL based on inbound links. The URL appears so at least put in the search results! See this example of Auping.nl. (Read the explanation from Google and Yahoo).Require removal URL
You can not just remove something from Google. The URL where the information on it that you want to remove from Google, one of the following requirements:

    It must include the 404 (not found) or 410 (gone) error message
    The URL must be blocked in robots.txt
    It must include the robots meta tag with the value "noindex" contain
How long before the information is removed?
Where one of the above requirements are met, the URL (after the application like Google Webmaster Central) as soon as possible.
Google shows that the 3 to 5 days, but usually goes faster. Also, I have seen situations where it happened in half a day.How long will remove the URL?
The URL remains from that time on six months (180 days) from the Google index (unless you do a reinclusion request to get back in the index to come).
After six months going back to Google Google crawl and then index the URL, if the information is still excluded from indexation in the robots.txt file or robots meta tag.Third party information removed from Google
The above options are available for a website to your full control. It can however also be that you would like to have information removed from Google for websites that are not under your control.
In that case you Google the above mentioned removal request (Google Account).A page from a third party to remove from Google
It might be that you are a webmaster of a website have requested a page or delete them. This webmaster does this then neatly through robots.txt or robots meta tag.
Subsequently, however, as described above, sometimes even weeks to months before the information from the Google index is removed.
So in that case you can submit a request to remove the URL. It simply hasten the process of removal from the Google index. Note: This only works if the URL information to the above requirements!A cached version of a page from Google
If a URL is excluded (via robots.txt or robots meta tags) for indexing, and if the removal process is accelerated by the use of the tools discussed above, there is still a cached version of the information.
As a website owner can be so easy with Google Webmaster Tools, or the value "noarchive" Robots Meta tag in the cached version is based.
On each page, which you want to remove from Google cache, insert the following code into the HEAD section of your HTML document:
How to remove personal information from Google?
If, at any page of your personal details are and the respective webmaster will not delete, you remove the personal information to Google (via the aforementioned tool). The personal information should one of the following requirements:

    Your Social Security number
    Your bank account or credit card number
    An image of your signature
    Explicit content that violates Google's guidelines and your personal information.
Google search history
Interesting in this context is a trip to the Google search history that keeps track of you. This information is not true in the Google index, but it may be desirable to your Google search history delete (or disable).
A more detailed explanation, explanations and instructions on the Google search history and remove or disable it can be found in my web history guide Google search history (and consequences for results, and privacy).Other information from Google Delete

Google web history, search history (and results and implications for privacy)

Google's search history as part of your Google Account extended to web history, so did the company announced yesterday. It lets you use Google, in addition to your queries, to remember which sites you've visited, in short, what your "clickstream" is.

Until February 2007 this was optional, but since February 2007 for anyone with a Google Account, your search history by default. Danny Sullivan has an interesting article written about extensively and which completely describes the change and consequences.
Google collects the search history, web history and expansion into a lot of information from many users. For now Google does not sneaky and there are clear steps that indicate that something is happening.

Search History interrupt

Google Search History verwijderenJe can interrupt your search history and / or remove items. So your searches are not stored in your Google account. Google will use IP addresses and server log data still store information about you, but that's hardly personalized and therefore requires no cause for worry.

If you're not enamored of the fact that Google knows what you are looking for and where you surf, you can permanently remove from your search history your Google Account.

Do you still use the Google Toolbar, but you do not want Google information about your surfing habits and search behavior to find out? Then you can log out of your Google account in Google Toolbar:

Google Toolbar with PageRank

google-toolbar-pagerankAls you've installed the Google Toolbar and PageRank option is DISABLED, then the same as your search history (as described above). However, Google will recommend the option to enable PageRank.

Google is great in terms of personalization and will grow further. According to Danny Sullivan is personalizing high on the agenda of Google in 2007, since Google is developing many initiatives in this area.Personalize the next step in search
The more Google knows about you, the more you Google a better and more unique (search) experience to offer (and the more relevant and personalized ads they can focus on you!). Personalizing search results is often seen as the next step in searching and providing better (more relevant) search results.
Google Ramps Up Personalized The article search for Danny Sullivan explains well how the personalized search at Google to work and the idea behind the next generation of search.Factors that influence personal search
The most important factors for Google personalized search results to be influenced to date:

    Websites where someone clicks on the search results
    Web sites added to the Google Personalized Homepage
    Web sites stored in Google Bookmarks
Google Toolbar, and (personal) search results
To the above list of factors that influence personal search is now added a fourth factor: the websites you visit. Google has so far indicated that the information that the Google Toolbar does not collect is used for influencing the results.
From now on, the information that Google collects so DO Baar tool used for the ranking of search results. Initially for your personal results, but probably also for the general Google search results.Is it necessary to worry?
With the announcement of this action is whether we should worry more relevant. Google grows, growing and growing, with no limits seem to be. Results from Google continued to grow as the company changes from a "tech company" to an "advertising" company, where the acquisition of DoubleClick is a clear example.

What kind of company is Google?
Google's Page & Brin Schmidt Eric Schmidt, CEO of Google, this also in an interview with Wired last week. We have Google as:

    An advertising company
    An end-user system (combination of operating system and office suite software)
    A gigantic supercomputer
    A social phenomenon
But where is the mission of Google go? "All the world's information universally accessible and usable"?Most attention (wrongly) to Google
On the other hand, Yahoo and Microsoft know at least as much from us as Google, but the attention to Google's size and reputation of Google. That is unfortunate, but a fact.
Vs. privacy. transparency and control over your search datagoogle-logo-large-hand, this move by Google is actually quite good, especially in the area of ​​transparency. Google Web History lets you see exactly what information they have of you. That can not (yet) be said of Yahoo and Microsoft ...
From now on you as a seeker of insight into your Google search data that Google has stored, but - perhaps more importantly - is that Google is increasingly YOU control over what information Google stores about you!
And that to me is a good step toward greater transparency in the search engines and protect your privacy, as I deemed necessary and described in the annual Search Marketing 2006.Is it so necessary to worry about your privacy?
No, but of course you should always be careful with your personal data. But we also need to 'sacrifice' to do. If you want something from a company (in this case, information), you must provide a return (in this case information about you). That way you'll get the information you want and you can companies (and their advertisers or other interested parties!) In the future with better service.
ConsciousMost importantly, be aware of what personal information you can and can make available to external parties. All developments, especially related to the Internet, showing that end-users, you and I, more and more control. I believe that in the near future, virtually complete control over your personal information. And Google is well on its way to give you that control.More information Google web history and personalized search
