Google Updater, the New Installer for Google Software

Last year, I posted that Google intends to install all its applications through Google Updater, the central component of Google Pack. At that time, a small number of people were redirected to the integrated installer, but this behavior has now become a standard practice.

Because some of the files from Google Earth were corrupted, I had to uninstall it. When I went to Google Earth's download page, Google informed me that I have to install Google Earth with Google Updater.


Google Pack's help center gives some reasons why it's convenient to use the Updater, but most of them help Google promote other software. "The Google Updater makes the software installation process more convenient in several ways. First, it installs software easily with just a few clicks. Also, once the Google Updater is installed, you can choose to have a system tray icon notify you when new software becomes available. Finally, the Google Updater provides you with a central place from which you can download more Google software, as well as other software we think you'll enjoy." (my emphasis)

Probably the only reason why I use my computer is to install Google software and this updater finally helps me get things done. If I want to install Google Earth, it's obvious that I should be informed if Google launches other applications and I should be able to install them with a single click. Hopefully, in the next iterations of the Updater, the click will be eliminated and the new software will be installed automatically after analyzing my interests.


I installed Google Earth using the updater and the setup was launched in the background, with the default settings. Google Updater is installed as a system service that starts automatically, places an icon in the system tray and constantly pings Google to see if there are any updates for the Google software installed on your computer. By default, the application installs the updates automatically and can be uninstalled.


Google still offers the chance to install applications without the updater, but the page that points to the direct links is too difficult to find and has an inappropriate title. I'll repost the links here, for convenience.

Google Earth for Windows:

Google Toolbar 4 for IE:

This practice is not Windows-only. Google's Mac software is installed only with the updater. "Google Updater is the installer for Google products on the Mac. You can use Google Updater to see which Google software you have installed and to see other Google applications you might be interested in. Google Updater helps keep your software up-to-date by installing updates when they become available. And you can use Google Updater to uninstall Google Software." Probably the most outrageous part from the Mac FAQ is the answer to the question: how do I uninstall Google Updater? "To uninstall Google Updater, you first have to uninstall other Google software on your computer. You can't uninstall Google Updater while you have Google software on your computer because we need it there to keep your software up-to-date."

Maybe Google should focus less on "we" and more on "you". Most Google software already has an option to auto-update and this could be easily added to the applications that don't have it. If the installers are too confusing, Google could simplify them and remove the unnecessary steps. I don't want to imagine what would happen if each application installed a system service for auto-update and used your network connection to constantly check for new updates.

Update: Apparently, I was lucky to install Google Earth in Firefox. If you use Internet Explorer, Google adds the options to install Google Toolbar and to set Google as the default search engine. Both options are enabled by default, so a standard Google Earth installation bundles Google Updater, Google Toolbar and changes your default search engine in Internet Explorer. This is way too much.

Google Starts to Index the Invisible Web

Google Webmaster Central Blog has recently announced that Google started to index web pages hidden behind web forms. "In the past few months we have been exploring some HTML forms to try to discover new web pages and URLs that we otherwise couldn't find and index for users who search on Google. Specifically, when we encounter a <FORM> element on a high-quality site, we might choose to do a small number of queries using the form. For text boxes, our computers automatically choose words from the site that has the form; for select menus, check boxes, and radio buttons on the form, we choose from among the values of the HTML. Having chosen the values for each input, we generate and then try to crawl URLs that correspond to a possible query a user may have made. If we ascertain that the web page resulting from our query is valid, interesting, and includes content not in our index, we may include it in our index much as we would include any other web page." For now, only a small number of websites will be affected by this change and Google will only fill forms that use GET to submit data and don't require personal information.

Many web pages are difficult to find because they're not indexed by search engines and they're only available if you know where to search and what to use as a query. All these web pages create the Invisible Web, which was estimated to include 550 billion documents in 2001. "Traditional search engines create their indices by spidering or crawling surface Web pages. To be discovered, the page must be static and linked to other pages. Traditional search engines can not see or retrieve content in the deep Web -- those pages do not exist until they are created dynamically as the result of a specific search."

Anand Rajaraman found that the new feature is related to a low-profile Google acquisition from 2005.

Between 1995 and 2005, Web search had become the dominant mechanism for finding information. Search engines, however, had a blind spot: the data behind HTML forms. (...) The key problem in indexing the Invisible Web are:

1. Determining which web forms are worth penetrating.
2. If we decide to crawl behind a form, how do we fill in values in the form to get at the data behind it? In the case of fields with checkboxes, radiobuttons, and drop-down menus, the solution is fairly straightforward. In the case of free-text inputs, the problem is quite challenging - we need to understand the semantics of the input box to guess possible valid inputs.

Transformic's technology addressed both problems (1) and (2). It was always clear to us that Google would be a great home for Transformic, and in 2005 Google acquired Transformic. (...) The Transformic team have been been working hard for the past two years perfecting the technology and integrating it into the Google crawler.

It's not clear what are the high-quality sites used by Google for the new feature, but this list includes some good options. Along with Google Book Search, Google Scholar, Google News Archive, this is yet another way to bring to light valuable information.
