Google Algorithm – Autocomplete

Internet is a source of information and its prime objective is to educate.  Google is the largest search engine that searches exact information on trillion of web pages available on the Internet

 which uses different algorithms, approx 200 types, to refine its search results.  Algorithm is a computer programme to take a query from you and to put forth an answer to a particular query.

One of the above algorithms is ‘Autocomplete’. What does it do and how does it do?  Let’s examine. Autocomplete means word completion.  We press keys of different characters on our computer’s keyboard to search specific information in Google’s search box.  Google start to apply its intelligence from the first impression of the key in its search box. It suggests you all the common options available, which have been chosen frequently, with the impression of the first key in its search box.  You can find maximum 10 options at a time in the search box for the related query but you have to opt for one, mentioning ‘I’m Feeling Lucky’.   You can see a sign ‘>>’ after ‘I’m Feeling lucky’.  If we click that sign, we will be directed immediately to the relevant website or webpage.

If you want to search ABCD, Google’s intelligence search will function in A B C D form i.e. we have to create impression of the first key as ‘A’, the next impression will be ‘B’ and so on. It might be possible that with the first impression of ‘A’ only, Google quickly provides an option of ABCD.  Web developers are also using Autocomplete option in their websites using html, asp.net and jquery, etc.  But, it is not mandatory for them to follow Google’s suit.

The benefit of this algorithm is that a user has to type few letters; less than what is required, for a particular search and they will find quick suggestions which help them to save their time by typing less.  This algorithm also helps to correct the spelling errors.  You start to type a wrong spelling and Google will suggest you the most frequently used spelling for the related query.  Also, it repeats the results for its users. It means if you have searched something on Google while you are signed in keeping your search history on, Google will try to provide the exact web results that you have already searched for. 

One of the features of its intelligent search is that it provides immediate answer to a question.  For example: if you type 1Kg is equal to how many pounds, you will find the exact answer i.e. 2.2046 below the search box.  It will hardly take less than a second to answer your query.

The Autocomplete algorithm helps Google to note down the data on any keyword.

The algorithm helps to control spam to a great extent as it allows user to report to Google, if they experience unwanted and unrelated results on the search engine.
