Why google search says sorry?

These days, google is irritating us. when we try to do some quick search it redirects us to page saying “We’re Sorry… but your computer or network may be sending automated queries. To protect our users, we can’t process your request right now. To continue searching, please type the characters you see below: “. It looks disgusting to us. But what is the reason behind it?

Google prevents automated queries

Sorry page is the page Google serves you (or an application) when you fail to answer it’s human-verification question. Google has instituted this new policy – randomly checking to see if queries submitted to it (ie. searches) are done by human beings (as opposed to software applications). The purpose of this is two-fold. On the one hand, blocking the search query and redirecting the user to sorry page alerts the user to potential spyware on their PC; on the other hand, it prevents users from utilizing software to query the Google search engine.

Google protects you from spyware

On the sorry page, you’ll see Google recommending you run anti-virus and anti-spyware checkers. Why? If spyware is present on your computer, it may be accessing the Internet, and will often execute Google queries. If Google detects this, instead of giving the application what it’s looking for, it will block the request and serve the sorry page instead. On this page you’ll see recommendation for you to scan and clean your PC in the event of an infection.

Google blocks Google ranking and utility tools

Just because you see the page sorry page doesn’t mean your PC is infected with spyware. It’s also possible that you have a browser plugin (Firefox add-on) or software utility installed, such as a Google ranking checker, that performs regular Google queries. Since Google randomly executes human verification, the utility will get caught, and eventually the sorry  page will get served.

While this reduces the load on Google’s servers, it also prevents software and utilites that rely on the Google API and querying capabilities to function. Bottom line, if you’re repeatedly getting this error, you should run an anti-spyware utility (such as SpyZooka), first, and then check your browsers for plug-ins (such as Google rankings tools, etc.) and other software that might be accessing the Internet and querying Google.

Google Caffeine

Google caffeine was under development for the past few months. It is a major update to Google infrastructure and includes no UI changes. Caffeine takes up nearly 100 million gigabytes of storage in one database and adds new information at a rate of hundreds of thousands of gigabytes per day. Most users won’t notice a difference in search results, but web developers and power searchers might notice a few differences. Google caffeine had been tested by many webmasters and it received positive feed backs. First it will be tested in one data center and later implemented in other data centers. The new Google caffeine will be

  • Fast.
  • Relies more on keywords.
  • Improve indexing speed, accuracy, size, and comprehensiveness.
  • Search is moving into real-time. News, information and social media results are set to be boosted by Caffeine, with this all being part of the large effort to make real-time search a reality.
  • Crawling and indexing may change.
  • Powerful, flexible and robust in the way pages are indexed.
  • More importance will be given to the exact matching domain names.
  • Local results even if you are not logged in. Your location may be detected based on the IP address or ISP.
  • Caffeine provides 50 percent fresher results for web searches when compared to the old search.

Tips for webmasters

  • Rankings are unlikely to fluctuate.
  • Keep your site fresh to be crawled by Caffeine. If your site is not updated regularly you may lose your rankings.


Googles New Search Engine Index “Caffeine”

Google has just unveiled a “secret project” of “next-generation architecture for Google’s web search“. This new architecture appears to include crawling, indexing, and ranking changes. For the first time, Google isn’t simply incorporating these changes into their existing infrastructure or replacing it. Instead, they’re providing a developer preview and are asking webmasters and power searchers to try it out and give them feedback. Unlike Google’s now-defunct Search Mash, which was intended for search experiments that wouldn’t necessarily be incorporated into Google’s main web search, the caffeine index seems to be an entirely new search infrastructure that will replace what exists now.

Based on the blog post, we can guess that this new infrastructure may include ways of crawling the web more comprehensively, determining reputation and authority (possibly beyond the link graph and what’s typically thought of as Page Rank), and returning more relevant results more quickly, although Google’s Matt Cutts told me that the changes are “primarily in how we index”.

While the biggest visible changes in Microsoft’s relaunched search engine, Bing, are user-interface related, Google’s new search is only infrastructure related and includes no UI changes. On first glance, however, the underlying infrastructure changes do seem to have impacted user interface as it relates to universal search (likely because universal results are influenced by ranking and relevance signals). For the sample searches I did, the first ten results were fairly similar, but the existence and location of images, video, news, and blog posts was notably different.

A search for on the new infrastructure, for instance, returns video and news results midway down the page.

A search on the existing infrastructure, however, returns news at the top, video in the middle, and images at the bottom of the page.

Undoubtedly, Google Caffeine will cause quite a kerfuffle in the web developer and search engine optimization world and many will dive in to try and figure out the changes. We’ll likely see many a speculative blog post about how best to optimize for the new infrastructure, but my guess is that it likely does what Google search does, but better. And the foundational elements of having a crawlable infrastructure and compelling content remain.


Android (operating system)

Android is an operating system for mobile devices that includes middleware and key applications, and uses a modified version of the Linux kernel. It was initially developed by Android Inc. a firm later purchased by Google, and lately by the Open Handset Alliance. It allows developers to write managed code in the Java language, controlling the device via Google-developed Java libraries.

The Android operating system software stack consists of Java applications running on a Java based object oriented application framework on top of Java core libraries running on a Dalvik virtual machine featuring JIT compilation. Libraries written in C include the surface manager, OpenCore media framework, SQLite relational database management system, OpenGL ES 2.0 3D graphics API, WebKit layout engine, SGL graphics engine, SSL, and Bionic libc. The Android operating system consists of 12 million lines of code including 3 million lines of XML, 2.8 million lines of C, and 2.1 million lines of Java.

The unveiling of the Android distribution on 5 November 2007 was announced with the founding of the Open Handset Alliance, a consortium of 65 hardware, software, and telecom companies devoted to advancing open standards for mobile devices. Google released most of the Android code under the Apache License, a free software and open source license.
