Do search engines search the entire web?
No, they search only a fraction of the entire world wide web, called the surface web. There is a lot of information in this fraction, but it is not the entire world wide web. The deep web is the portion that is not indexed by search engines and is several times larger than the surface web.

Search engine optimization involves a series of processes in order to improve the volume and quality of traffic of a website. It is a wide subject. Strategy that r…elates to it changes or updates once in a while. We can divide it into two parts: on-page and off-page optimization. The on-page optimization relates to the architecture of your website and its content and how your target keyword is optimized to it. Off-page optimization refers to factors that have an effect on your website or webpage listing in natural search results. These factors are off-site in that they are not controlled by you or the coding on your page. Some off-page optimization techniques include article submission, blog posting, forum posting, blog commenting, guest blogging, directory submission, social bookmarking and networking, press releases, and RSS feeds.

A web search engine is a website based software system that is intended to hunt down data on the World Wide Web. The query items are for the most part introduced in a line… of results regularly alluded to as search engine results pages (SERPs). The data might be a blend of website pages, pictures, and different sorts of documents. Some web indexes additionally mine information accessible in databases or open catalogs. Not at all like web registries, which are kept up just by human editors, web crawlers additionally keep up running so as to ongoing data a calculation on a web crawler.
It is the search engines that finally bring your website to the notice of the prospective customers. When a topic is typed for search, nearly instantly, the search engine w…ill sift through the millions of pages it has indexed about and present you with ones that match your topic. The searched matches are also ranked, so that the most relevant ones come first. It is the Keywords that play an important role than any expensive online or offline advertising of your website. Further, they all use one of the top 6-7 search engines and these search engines attract more visitors to websites than anything else. So finally it all depends on which search engines the customers use and how they rank your site. Remember that a prospective customer will probably only look at the first 2-3 listings in the search results. So it does matter where your website appears in the search engine ranking. It is found by surveys that a when customers want to find a website for information or to buy a product or service, they find their site in one of the following ways: The first option is they find their site through a search engine. Secondly they find their site by clicking on a link from another website or page that relates to the topic in which they are interested. Occasionally, they find a site by hearing about it from a friend or reading in an article. All search engines employ a ranking algorithm and one of the main rules in a ranking algorithm is to check the location and frequency of keywords on a web page. Don't forget that algorithms also give weightage to link population (number of web pages linking to your site). When performed by a qualified, experienced search engine optimization consultant, your site for high search engine rankings really does work, unless you have a lot of money and can afford to pay the expert. With better knowledge of search engines and how they work, you can also do it on your own. Thus it's obvious the most popular way to find a site, by search engine, represents more than 90% of online users. In other words, only 10% of the people looking for a website will use methods other than search engines.
How does a search engine let you search for information on the web? There are two different kinds of search engines - one is a crawler-based search engine (spider),… and the other type is a human-driven directory - and they both gather and create their listings in extremely different ways. Human Driven Directories (e.g. Open Directory) uses humans to build their listings. One submits a short description for a website to the directory or the directory has editors that write a description for sites they review. Crawler Search Engines (e.g. Google) uses spiders (automated software program that "spiders" the content of a website). The spiders go to a web page, read the content there, and follow any links it comes across along the way until it reaches a dead end. The spiders then index the information it gathers in a giant catalog. Spiders will revisit a site every month or two and update any changes that occur on that site. The final aspect of how the search engines work is the search engine software program goes through the millions of web pages recorded in the index and finds a match to a search ranking them in an order based on what that search engine believes to be most relevant.
If a web search engine was "drawn" on paper, it might look like a sun with lines for rays (links). Plus, superimposed amongst the "rays" would be triangles, squares, and diago…nal lines between and among all the different "rays". As an example, Website A is about Cats and contains 55 pages. From it's main page, it contains 110 internal links (within Website A) and 32 external links (going outside Website A). On each of it's 55 pages, it also contains internal and external links. Let's say this Website A has a good amount of traffic or uses keywords, so it appears in the top 20 entries of Google Search for "cats". Looking at the main page with 32 external links (going outside Website A), we (or a web-bot spider) can follow each of these links to see where it goes. Let's say 2 links go to individual friends' sites; 6 links go to major Cat Food companies and their websites have information how-to pages; and the rest go to single pages on let's say Wikipedia, Answers.com, WikiAnswers, Encyclopedia Britannica, and other sites that have entries about the subject of cats. Web spiders crawl each link to where it ends. This creates the "rays" in our drawing. But webs also have internal links. So this website about cats may link from it's main page to a page on "characteristics of cats"; "types of cats"; "breeds of cats"; "cat vocalizations"; "cat products"; "cat books" etc. Each of these pages is it's own entry point into the entire website (so it's a "ray"). But, these pages can criss-cross to each other (one or several) as well as link to outside sites. This criss-crossing is what makes the other shapes that we could superimpose on top of the "rays" in our drawing. In many ways, web indexing can be compared to using paper to brainstorm with the main topic in the center of your paper. Under one topic, you could write bunches of words or phrases all over the page (not on lines, neatly - instead, just anywhere). If you drew lines from each thing you wrote back to the center of the paper, they could overlap (superimpose) or go directly back to the center. Now, let's say on this that 9 of your classmates also did a brainstorming paper and drew their lines back to the centers of their papers. If you then took all 10 of your papers and tried to "link" one or more lines, in a logical way, your papers could all overlap. In addition, just as Website A might link externally to Website B, there might be a Website K and a Website W that link back to Website A. So every website has what it links to, plus websites that link to it. This would also be as though 10 more students had brainstormed on separate papers and then tried to logically link onto the 10 original students we described above. Search engines on the Internet take the hodgepodge of millions of different websites and the "links" through the TOPIC (the keywords). When you search for "breeds of cats", the search engines show you those results-- it wouldn't show you "breeds of zebras" (unless a cat page mentions zebras!). But what you don't see is how one website links to the next, because web content is kept in folders. You'd need to look at the URLs to see the folders and make an outline to really understand how one website is put together. Additionally, you'd need to list all the external links.... then, go to those sites to do more outlines of those sites, showing how they also link into the first site. New webmasters should, in fact, draw or outline their site before starting to make webpages. This helps to visualize how each webpage will link to another webpage, and so on, and helps to organize the content and the website.
The purpose of a web search engine is to help people search the internet and find the information that they are looking for. Some popular search engines are Yahoo and Goog…le.
A web browser is different than a search engine. A web browser is used to look at webpages located on the Internet, while a search engine is a website that you can go to searc…h for webpages, like Google, Yahoo, or Bing. Search engines are viewed from a web browser. Unless you use the Google Chrome web browser, then your browser doubles as your search engine.
To many to count. There are many private onse so people cannot tell. There are many search engines most popular are Google,Yahoo,Bing,Ask, Entireweb,Gigablast,Teoma,AltaVista…,e.t.c.
A Web search engine is a Web site that returns an ordered list of hyperlinks to Web pages based on the characters, words, set of words or phrase the user has entered into …the search box. The order of the results are based on a combination of factors but a page's computed relevancy to user input is most important. The idea behind a search engine is: The search engine has a lots of small software that downloads the Websites and then it indexes them like this: Answer work, exists in A, B, C, D Web pages Question work, exists in B, D, F Web pages So if you searched for "Question Answer" the search will return hyperlinks Web pages B and D display them in the search engine's "results" page. Today there are many search engines like: Google, Yahoo, Bing, Kngine. Well, a search engine is a program that locates documents containing user-specified keywords and returns an ordered list of the hyperlinks to those documents where the keywords were found. Other than specified above I use Ask and AltaVista also.
Google is a search engine, like yahoo/ Bing etc, it is a website. A web browser if the one in which you open your website. Internet explorer, Firefox etc are web browsers. … Google Chrome is also a web browser, however the website Google is a search engine.
The number one search engine is currently google. It is followed by Yahoo, and Bing follows in third place.
Very many search engines exist today. The most common are Google, Yahoo! and Bing. It would be very difficult to list every single browser out there so there will probably not… be anywhere where a complete list can be found. Bonus note: Several human-assisted and even human-based search engines exist also.
I know about Google Only.In September of 1998, Google Inc. opened in Menlo Park, California and Google.com, a beta search engine, was answering 10,000 search queries every day….On September 21, 1999, Google officially removed the beta (test status) from its title.
