How Search Engine Operates?

Search engines have there own algorithm or are a mixture of algorithms that allows them to provide relevant web results when searchers find the information.

Crawling the Web:
Automated programs used by search engines, called "Bots" or "Spiders", that use the navigation structure of the web to "crawl".

Indexing Documents:
Web crawlers create a copy of all the visited pages and index them in there database.

Processing Queries:
When a request for information is comes into user interface (Search box) then it will automatically transferred to the search engine then search engine retrieves from its index all the document that match the query.

Ranking Results:
In this process search engine has determined which results are most relevant to user query, Search engines follow a set of rules to extract the query, known as an algorithm which sort the results pages in order from most relevant to least so that users can easily make a choice about which to select.

What are Speed Bumps & Walls?

When search engine spiders crawl the web, crawler firstly crawl the architecture of web links to find new documents and revisit all those hyperlinks that may have changed. In the Conformity of words to the genius of speed bumps and walls, complex links and deep site structures with little unique content may serve as "bumps." Data that cannot be accessed by crawler links qualify as "walls."

“Speed Bumps" for Search Engine Spiders:
URLs with dynamic parameters; i.e. (http://www.url.com/index.php?id=42ak=34rr&User=%page%)
Pages with more than 100 unique links to other pages on the site
Pages contains more than 3 clicks/links from the home page of a website
Pages "Session ID" or Cookie to enable navigation
Pages that are split into "frames"

"Walls" for Search Engine Spiders:
Pages accessible only via a submit button.
Pages require a drop down menu (HTML attribute) to access them.
Documents accessible only via a search box.
Pages requiring a login.
Pages that re-direct before showing content (search engines call this cloaking or bait-and-switch and may actually ban sites that use this tactic).

Information Search Engines Can Trust?

When crawler index the structure of web links and web content, they Index two different information about a site (a) site attributes and (b) description about that site from other pages of a sites. As web is commercial place for all sites, where almost all sites interested in ranking well with there targeted keywords, the engines have learned that they cannot trust on websites to be honest about their importance. Thus, the days when artificially stuffed Meta tags and keyword-rich pages dominated search results have vanished and given way to search engines that measure trust via links and content.
The theory goes to Link popularity that if other websites link to you, your site must be popular, and thus, have value. If those links come from very popular and important sites like sites related to your theme, sites with high Page rank etc. then their power is multiplied to much greater degrees. Links from these sites inherent trust that search engines then use to boost your ranking position.

Some most important factors crawler look when attempting to value a link:
The Anchor Text of Link.
Global Popularity of the Site.
Popularity of Site in Relevant Communities.
Content Directly Surrounding the Link.
Content of the Linking Page.
