SEO History, Evolution and Important Updates

Search Engine Optimization

The Search Engine
The Search Engine has three functions Crawling, Catching, and Indexing.
Crawling- This is the scanning part of the search engine it scans each and every word of the web page and takes a snap shot of it.
Catching- This is the recording part, which records each and every minute part of a web page and saves it.
Indexing -  This is the categorizing part of it, it categorizes the subjects and inculcate into the suitable index where it is appropriate.

Search Engine Optimization (SEO) has some connection with the down fall of City Center of New York on 9/11/2001.  When the structure was crashed, there was numerous enquiries related with the incident. The Google was not able to give appropriate information about the queries of the people.  This happened because the web sites related with the city center where not tuned with the Key words of Google. In this juncture the management of Google made a decision to inform the webmasters about the suitable key words and the content to be specific that is to be presented for each category or subject. Thus how the birth of keywords came into effect. This lead to many manipulations like stacking of key words, putting key words simply in the body invisible to the reader and so on which compelled to penalized by the google. As the things came like this google changed its strategy from keywords to links. This is a system that if our web page has links to other popular sites we get credit or ranked in the toppers list.  As we know people always look for the loopholes, many links started to different sites which has no connection with the subject. This has started to question the integrity of google, which again brought more rules and regulations, leading to a system, which only links to the web pages which has rankings by the google is permitted. Now the things changed, what happened is the web pages which has rankings started selling their webpages for few dollars to other web sites. This has led to a system of passing the juice Seo. This can be explained in a manner like if a water tank has an 8 inch pipe for the inlet connection and 2inch for out let connection there will be always water in the water tank, means those web sites which has sufficient inward links only could give outward links. This link building technique still had problems because always a web page need to give links to many sites, this led to either passing the juice or giving attribution to the other sites. For this google came with an antidote, by giving a code – rel= “nofollow”> this means the credit of our web site will not pass to the other site, still link will be created.

Google AdWords – PPC (pay per click) is an advertising system of google in which the ad of any product can be given by making a payment. For eg. The ad of Samsung could be given by google by receiving an advance payment.  Whoever click the ad will reduce the deposit money payed by Samsung to google.  This is pay per click.

Google AdSense: -  is a system like affiliate marketing where the sticker of a company will be pasted (advertisement) in our web page provided by google and if there is any click we will get money from google as well as google will be also benefits from it.

The reason could be the google was banned from crawling Facebook for few months. But still it is believed by the webmasters that the social medias have an upper hand in the ranking of SEO.

This model is called semantic search., "Google said that Hummingbird is paying more attention to each word in a query, ensuring that the whole query—the whole sentence or conversation or meaning—is taken into account."
