Google is a search engine and people search several things in Google to get accurate information. As per the huge database maintained by Google the search results crop up. Google uses a very realistic approach to this searching method and in the process they have developed an algorithm. This algorithm is known as hummingbird algorithm. It was made to make the search in Google more logical. In the world of Search-engine-optimization this new algorithm of Google will affect vastly. Previously SEO was mostly depended on the most searched keywords and their frequencies.
The new hummingbird algorithm will change the SEO concept. More stress has been put on conversational keywords. This concept will help provide more direct and realistic search results to the users. Google is trying to put a more rational approach that will be able to process real time speech patterns of human. Through Hummingbird algorithm Google is trying to understand the possible intents of every user. The long process of Google to read the mind of people looks more possible after implementation of the new hummingbird algorithm. This algorithm will give more importance to keywords that will be a part of conversation and more elaborative in nature.
1. INTRODUCTION
Google started using Hummingbird about 30 August 2013, and announced the change on September 26 on the eve of the company's 15th anniversary. The Hummingbird update was the first major update to Google's search algorithm since the 2010 “Caffeine Update”, but even that was limited primarily to improving the indexing of information rather than the sorting of information. Google search chief Amit Singhal stated that Hummingbird is the first major update of its type since 2001.
Conversational search leverages natural language, semantic search, and more to improve the way search queries are parsed. Unlike previous search algorithms which would focus on each individual word in the search query, Hummingbird considers each word but also how each word makes up the entirety of the query the whole sentence or conversation or meaning is taken into account, rather than particular words. The goal is that pages matching the meaning do better, rather than pages matching just a few words.
Expanded Knowledge Graph features focused on making it more usable. Hummingbird places greater emphasis on page content making search results more relevant and pertinent and ensuring that Google delivers users to the most appropriate page of a website, rather than to a home page or top level page.
1.1 WHAT IS HUMMINGBIRD?
The Hummingbird is an entirely new algorithm. It approaches search engine queries in a brand new and intelligent way utilizing new technology combined with older features of the existing algorithms. It is named for the speed and accuracy of the tiny bird.
1.2 THE RESURGENCE OF LONG TAILED KEYWORDS
The Hummingbird is what Google is calling the latest (greatest?) algorithm that they slipped in under our radar in August. Hummingbird will take a search engine query using long-tailed keywords and try to decipher the context of the question rather than chase the specific keywords within the question. The goal is to provide results that actually answer to the question.

1.3 PAGE RANK ALGORITHM
Hummingbird looks at PageRank how important links to a page are deemed to be along with other factors like whether Google believes a page is of good quality, the words used on it and many other things. A webpage‟s ranking is determined by analyzing the ranking of all the other webpages that link to the webpage in question. It is calculated as,
„n‟ = the number of pages in the web.
C (Tn) = the PageRank of each page by the number of outgoing links on that page .
d= damping factor decrease the influence of all of the pages in relation to the page in question.
