The formula Google uses to rank the resulting Web pages from a user's query. Along with the PageRank system that was Google's major contribution to evaluating website importance due to popularity, Google uses numerous other criteria that change periodically to deliver more relevant results as well as to prevent people from gaming the system. For example, if one criterion were the quantity of identical words in the page, search engine optimization (SEO) specialists might embed multiple occurrences of the word in the page that are invisible to the user but not to the search engine spider that crawls the Web. When Google finds that people are doing excessive "keyword stuffing," it may lessen the value of that criterion in the overall mix.

Google launched the Penguin Update in April 2012 to better catch sites deemed to be spamming its search results, in particular those doing so by buying links or obtaining them through link networks designed primarily to boost Google rankings. When a new Penguin Update is released, sites that have taken action to remove bad links (such as through the Google disavow links tool or to remove spam may regain rankings. New sites not previously caught might get trapped by Penguin. “False positives,” sites that were caught by mistake, may escape.

GOOGLE PENGUIN
Hummingbird;
It’s the name of the new search algorithm that Google is using, one that Google says should return better results.
So that “PageRank” algorithm is dead?
No. PageRank is one of over 200 major “ingredients” that go into the Hummingbird recipe. 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 (see our Periodic Table Of SEO Success Factors for a better sense of some of these).

GOOGLE PIEGON;
Launched on July 24, 2014 for U.S. English results, the “Pigeon Update” is a new algorithm to provide more useful, relevant and accurate local search results that are tied more closely to traditional web search ranking signals. Google stated that this new algorithm improves their distance and location ranking parameters.
The change is so significant that the date it happened is being referred to by a variety of names. Here at Search Engine Land, we’re calling it mobilegeddon, but sometimes it’s also referred to as mobilepocalyse, mopocalypse or mobocalypse.
The construction work for the metro will be carried out in two phases. The Phase I will be completed in six stages.
Phase I
Three lines are included in the Phase I and cover a distance of about 71 km. In the first stage, the metro routes between Nagole and Mettuguda and between Miyapur and S.R. Nagar will be made operational. The messages about the metros will flash in four different languages - English, Hindi, Telugu and Urdu in the display board in all the metro stations. In Phase I, following metro stretches will be functional:
Elevated world-class metro stations at a distance of approximately every kilometre.
It will connect major bus stations such as MGBS, Miyapur, Dilsukhnagar, Charminar Koti and Jubilee Bus Station.
Feeder bus services to metro stations from several areas are planned by GoT.

"RoSPA (Royal Society for Prevention of Accidents) 'Gold' Award" for Construction Safety and Occupational Health for the year 2013 at Glasgow (UK) on 19 September 2013.
Some Interesting Facts about Hyderabad Metro
The proposed rail project covers a length of 72 km with metro stations at every kilometre.
The estimated cost of the project is Rs 14,132 crores.
The number of commuters in the year 2015 are expected at 14,76,000.
It is expected that the project will serve three "high density corridors" with a frequency of three to five minutes during the peak hours.
There are plans to collaborate with other public transport systems such as MMTS and RTC to integrate the metro rail with them.
