Earlier Search Engines
There were many search engines prior to Google. But unlike Google, most of them used simple web-crawling techniques like, inverted indexing and term frequency. Essentially an inverted index, is a data structure which points to each instance where the term occurs, making lookups relatvely effecient and easy.
When querying terms using inverted indexing, the search engine would locate on which web-pages those terms were found. Inverted indexing will rank the web-page based on how the term was being used. Thus a web-page with that said term being in the title or header, would be more relevant than a web-page with a high number of occurances of that term. Term frequency, was used more to reassure the relativeness of a web-page rather than to rank the pages itself.
As people began to fimilarise themselves with the internet and how the search engines were used, exploits were found. Particularly, how pages were being ranked. People found it easy to trick others into visting their websites by either inlcuding the term in the title or header or by increasing the amount of times that said term occurs in their web-page. For instance, people who sell cars could easily exploit the weaknesses

Corrado also mentioned to Bloomberg that RankBrain has become the third-most important ranking factor. This has stirred a lot of curiosity since it's probably the first time that Google has specified exactly how important a certain ranking factor is. However, the search engine giant outlined precisely how RankBrain can help websites increase their rankings, although many SEO experts have expressed their theories. How will this new system affect

Google was founded by two University of Stanford graduate students Larry Page and Sergey Brin. Their main objective of founding the company was to be able to retrieve specific data from massive amounts of information. The two developed a proprietary technology that would become the ultimate search engine. Initially the pair worked out of their dorm room, then a garage, and once they had quickly outgrown these "facilities" they had moved on to a much larger facility where they reside to this day. It seemed to be a matter of time before they had conquered the continental United States, and had begun to eye the lands across the pond.

First of all, where does the word “Google” come from? The name "Google" originated from a misspelling of "googol,” which refers to 10100, the number represented by a 1 followed by one hundred zeros. It found its way to the English language, now the verb "Google", was added to the Oxford English Dictionary in 2006, meaning, "to use the Google search engine to obtain information on the Internet." Their search engine was originally nicknamed "BackRub" because the system checked back links to estimate a site's importance. /// The start of Google was pretty much like the start of every website. It was a research project to these two Ph.D. Students where they hypothesized that a search engine that analyzed the relationships between websites would produce better ranking of results than existing techniques, which ranked results according to the number of times the search term appeared on a page. It was first related to the university’s domain, but then the traffic was so heavy that the university asked them to move their website to a domain outside the university. What made Google this popular was the speed it pulls out information, which is counted in parts of seconds. And also, the size of their data base, according to the instructor of our instructor in MIS class only 60% of data you found on Google are in other web search engines.
Internet commerce is one of the fastest growing industries today.
