2. Providing Answers

Providing answers to user queries, most often through lists of relevant pages that they've retrieved and hierarchic for relevance.

1. Crawling and Indexing

Imagine the globe Wide net as a network of stops during a huge town subway system. 

Each stop may be a distinctive document (usually an online page, however typically a PDF, JPG, or different file). The search engines want method|how|some way|the way|the simplest way} to “crawl” the whole town and notice all the stops on the way, so that they use the most effective path available—links.

The link structure of the online serves to bind all of the pages together. 

Links allow the search engines' automated robots, called "crawlers" or "spiders," to reach the many billions of interconnected documents on the web.

Once the engines find these pages, they decipher the code from them and store selected pieces in massive databases, to be recalled later when needed for a search query. To accomplish the monumental task of holding billions of pages that can be accessed in a fraction of a second, the search engine companies have constructed datacenters all over the world.

These monstrous storage facilities hold thousands of machines processing large quantities of information very quickly. When a person performs a search at any of the major engines, they demand results instantaneously; even a one- or two-second delay can cause dissatisfaction, so the engines work hard to provide answers as fast as possible.

 

 

 

 

 

   

    

2. Providing Answers

 

Search engines are answering machines. Once someone performs a web search, the computer program scours its corpus of billions of documents and will 2 things: 1st, it returns solely those results that are relevant or helpful to the searcher's query; second, it ranks those results in keeping with the recognition of the websites serving the knowledge.

Search engines usually assume that the a lot of common a web site, page, or document, the a lot of valuable the knowledge it contains should be. This assumption has verified fairly thriving in terms of user satisfaction with search results. 

Popularity and connection aren’t determined manually. Instead, the engines use mathematical equations (algorithms) to type the wheat from the chaff (relevance), and so to rank the wheat so as of quality (popularity).

These algorithms typically comprise many variables. Within the search selling field, we have a tendency to discuss with them as “ranking factors.” Awaiseo crafted a resource specifically on this subject:  Search Engine Ranking Factors.

Time For An Experiment

There is maybe no larger tool offered to webmasters researching the activities of the engines than the liberty to use the search engines themselves to perform experiments, take a look at hypotheses, and type opinions. it's through this iterative—sometimes painstaking—process that a substantial quantity of information regarding the functions of the engines has been gleaned. a number of the experiments we’ve tried go one thing like this:

1. Register a replacement web site with nonsense keywords (e.g., ishkabibbell.com).
2. Create multiple pages thereon web site, all targeting a equally ludicrous term (e.g., yoogewgally).
3. Make the pages as near identical as doable, then alter one variable at a time, experimenting with placement of text, formatting, use of keywords, link structures, etc.
4. Point links at the domain from indexed, well-crawled pages on different domains.
5. Record the rankings of the pages in search engines.
6. Now create little alterations to the pages and assess their impact on search results to see what factors would possibly push a result up or down against its peers.
7. Record any results that seem to be effective, and re-test them on different domains or with different terms. If many tests systematically come a similar results, likelihood is you’ve discovered a pattern that's employed by the search engines.
