About search engines

Search engines are functional devices in the work, which uses the following algorithm of work: by entering the user's keywords they collect information from registered resources ( indexing ), outputting the final result in the form of a list, constructed taking into account the attendance of the resource. So, the higher the attendance , the higher it is on the list of detected pages. The only difference is that each search engine uses its own way of indexing and counting attendance. It should also be noted that the method of ranking the list is also called, as a level of revalence.

The importance and importance of search engines can not be underestimated, since most visitors to most sites come with their direct participation. The search engine scans each page of the Web site separately, therefore, the more indexed pages the more success.

In the search engines when indexing, multifunctional programs that are also called spiders are used, so they "crawl" the World Wide Web, indexing the Web pages forming an index index. So owners of sites registering their domain names in search engines get spiders of these search engines. In addition to all, it must be said that when search engine spiders get to an indexed page, they follow the links of these pages and therefore they often, but not always, index the pages indicated by the links.

Technologies used in search engines change constantly due to technological progress and other important circumstances, in particular, the temptation to outwit the "robot" developers of Web sites. After knowing the features of a particular search engine, you can make your own peculiarities in the page code. To keep up with the changes, you should regularly update your knowledge in this area, including by subscribing to newsletters about the state of the search engine industry.

Speaking of search engines, you can not ignore such a segment of the Internet as directories. In their importance they do not differ from search engines. Here you can give an example that the Yahoo! search service with all its functionality on the World Wide Web is not at all a search engine, but is considered a catalog . Catalogs on the principle of their work differ in that in most cases they contain a description of the site as a whole and as a rule, in catalogs there is no description of individual pages. Those. In the directory, you can register only one page, usually the main page, although there are exceptions. Another difference is that when building an indexation index, they rely only on information about the registration of the site owner. After registering a site in the directory, it is usually viewed by the editor, and it decides whether to leave the site in the directory. Then the owner receives an index on his website based on the form that he filled in when registering in the catalog.

A lot of search engines, as well as directories, are interrelated . If this is seriously taken care of and learn all their interrelations. then you can save a lot of time when working with search engines. So by registering a site on one search engine, the latter can include your site in a database of several other search engines. A striking example of this can be that Google provides its database for Yahoo! , and Yahoo! in turn for Google. If you are interested, write us an e-mail with a request to send a table of relationships between the main search engines and directories with a return address and you will receive it for free.

When working with search engines must take into account the requirements of some of them, so the Google search engine will start indexing your site only if there is a link to it. When registering, a special form is filled out, in which the necessary information is indicated, then the site falls into the queue for registration. Terms for each search engine are different.
