What is Google Caffeine?

How Google Caffeine Will Change Google Search

Google Search Results
Google Caffeine won't change how the search page looks.

Google Caffeine is the latest update coming to the Google search engine, but unlike other updates, Google Caffeine is a reboot of the search engine. Rather than simply introduce new changes within the current system, Google has opted to completely retool the search engine with a goal of achieving greater speed, better indexing a more relevant search results.

Why not just add Google Caffeine to the current search engine? Think of it as putting oil in your car. You can just add a new quart when you are low, but every once in a while, you need to change out the oil completely to keep everything running smooth. Computer programs that receive frequent updates aren't too different. Each new update may add a feature, or even increase performance, but as time goes on, the whole of the parts becomes more disorganized. By starting with a clean slate, Google can implement the latest technologies in an organized fashion in order to achieve the best results.

Speed. This is the main goal of Google Caffeine, and if testing in the sandbox is any indication, Google has achieved this goal. Search results are loading up to twice as fast as previous results, though performance may be impacted when it is rolled out to the world as a whole. But speed isn't just about loading the results fast. Google is also aiming for Google Caffeine to speed up the time it takes to find a page on the web and add it to their index.

Size. The more results that can be indexed, the better results that can be achieved within the search result pages. Google Caffeine increases the size of the index, with some search results pulling back 50% more items. Though in terms of raw size, Microsoft's Bing seems to have the largest index.

Relevance. While speed and size are the easiest to test, the relevance of Google Caffeine's search results might make the biggest difference. Google is working to create a smart algorithm that can bring back results better suited for the search queries. This means trying to interpret what the person is truly searching for and bringing back relevant pages. It also means a bigger emphasis on keyword phrases.

Google Caffeine: What Does It Mean to You?

Speed, size and relevance sound good, but what does Google Caffeine really mean to the end user? Will it change how we search? Should we expect to see something different?

Those patiently waiting for its release might find it a little anti-climatic. Google Caffeine will have the same look and feel as the current Google search engine. In fact, most people probably won't even notice its launch. In the end, Google Caffeine is not so much about making a big splash in the search engine market as it is a vital step towards making sure Google is prepared for the future of search.
