If you think that you should write letter in order to obtain invitation to the yearly dancing party in headquarters Google in GooglePlex, then I think, for you it definitely is worthwhile to read a little this division in order to understand, as precisely works the base of data Google and its robots. Although already sufficiently is much known about the monthly renovations of the base of data (still loving them they call “Google Dance”), recently they more and no longer are similar one on top of the other, and therefore for beginning vebmasterov - this as gigantic jump into the void, where one can see nothing all around. And on this they with the impatience await each monthly renovation, hoping for the highest forces.
Each “dance” begins from the main, global search. Let us name This “search A”. However, what does occur at this time? In principle, nothing special - the spiders attend entire base of data (more than 3,4 billion pages on the last calculations). For this at disposal Google are located more than 15,000 inexpensive computers (on the essence, usual desktopov), which are scattered 0 0N throughout the world and are located in different date- centers. At this time Googlebot they attend all pages from the base, and also search for new, which recently appeared to the light. After the end of “search A”, when all pages are fixed in the base for the following renovation, follows the second search, approximately 2 weeks after the first.

And since Google does nevertheless renew its data base? A question sufficiently extensive, but I will attempt to explain to you each step of system, which each month checks its data base against the correspondence to the highest standards.
The majority of people and companies it understands, that for achievement of the highest place in the search it is necessary to previously think over all steps both prior to the beginning of the optimization of resource and to compile the plans of actions on the future. Google today remains one of a few search systems, which acts on the free basis for the sites of participants. Also references to your resource in its data base appear by some of the first, and according to given, obtained on 10 July, 2003, the world base of data Google counts more than 3.4 billion pages! But indeed this is only drop in the sea, since many pages are not accessible for the indexing to the spiders of system.
As in the life, there are many risks and complexities, which encounter the owners of sites, webmaster and professional- optimizers with the starting of their marketingovykh programs. Although the majority of experts agree with the fact that Google sends robots before and after the specific periods, practically no one them them can with the confidence say, when precisely, what number system will conduct basic scanning and it completely renews its data base. In this article we will examine fundamental component “Google Dance”, and also when and as to recognize robots, and as to consider this factor for the optimization of its site.
Each experimental webmaster knows that, in order to fall into base Google or to renew the already existing there information, is necessary thoroughly everything to plan and “to catch” Googlebot precisely at the necessary point of monthly cycle. The majorities of experts for the optimization separate the first search, which carries out Googlebot in the beginning of month, and the second - during and immediately after the renovation of the data base.
Thus, stands the task of placing site into the base data google. Question: is guaranteed whether the start of site in the data base with the visit by its robot of system during these searches? Judging by our experience - not always. Being more precise, if spider attends site in the beginning of month, i.e., all chances to the fact that it not will be included in the renovation of this month. But if spider visited to the site during the second search, which follows immediately the renovation, then it is very probable (but not assuredly) that it will visit to it and during the following search, and then it will include in the renovation for the following month.
Sometimes spider can simply visit to the new site and examine only his main page and file Robots.txt. This is a good sign, since this means that Googlebot will return here during the following large search and site will be included in the renovation, which follows the second search. Thus, in order to new site to fall into the data base, it will be required two visits Googlebot, although the exceptions from this rule also occur.

Friday, January 14, 2005Company WordTracker prepared the special release of its weekly bulletin Weekly top 500 wordtracker keyword report, where on this week entered also Top300 surge report - 300 most popular demands in the recent 24 hours on the basis of data of the search systems Metacrawler/Dogpile and others. Events in America were reflected and here - in tens of the most popular demands only two - yahoo and hotmail - do not relate to the theme of acts of terror in the USA. The complete list of demands with the indication of their quantity is given below. In all are processed 5,581,719 demands.
Friday, January 14, 2005Lycos.com published the list of the most popular demands of 2001. Be omnipresenting did not fail to be sorry Britni Of spirs, yielded the first place for the Japanese cartoon DragonBal li of that moving for the second position.
Editors themselves Lycos note that, because of the events on 11 September, the list did not come out by the precise copy of last year’s, although undoubtedly there is nothing good in this - in the list of 50 demands the majority of new demands were caused precisely by acts of terror in the USA.
Before representing very list of demands, would be desirable to explain, that it is not entirely ideal. Editors Lycos removed from it the demands, connected with the pornography and some others, not serving as the index of interest in any theme. Thus, are removed monosyllabic demands like “music”, “auto”, Also the demands, which clearly relate to the specific company, thanks to which in the list there are no demands “Yahoo”, “Hotmail” others, very popular.
Friday, January 14, 2005Term the keywords will further relate to the words, entering text HTML of document and the assumed demand of the user of search system, that searches for information on the thematics, which coincides with the thematics of document.
Relevancy
Search machines calculate the relevancy of text, system pitch continuum of the words. The more frequent the word is encountered in the text, those large, with respect to the demand of user, it obtains relevancy.
Depending on the level of competition and stated problem a quantity of the keywords can vary from two - three to ten. The document is disposed to a smaller quantity the keywords, the greater the frequency with which these keywords can be encountered in the text, and the higher their relevancy.
The highly relevant documents are oriented toward two, three keywords, each of which is encountered in the text in the relationship close to 1 to 20 (5%). The keywords, which are encountered in the text with the larger frequency, can be perceived by search systems as to spam.
Friday, January 14, 2005Even if there is the question, assigned approximately with the same frequency by novices (both on the forum of this site and in other places) that also sacramental “as to me to untwist site?” , then is this a question “where to find the lists of the most popular words in the prospectors?”
With the entire practical uselessness of correct answer to this question (the fact is that the first tens of popular demands practically it does not change already several years), it to give simply. There is a popular service WordTracker (for the English prospectors), which gives the verification capacity of search words to the popularity, and, after using even free demonstration service with the reduced possibilities, you can sign to the weekly distribution, which contains the lists of the most popular words in the recent twenty-four hours and two months.
Friday, January 14, 2005Honestly speaking, me somewhat astonished the sequential release of distribution WordTracker, in which, as usual, were given the lists of the most popular search demands in the recent twenty-four hours and two months. Is forgotten Ben laden, to the second plan anthrax went away, people search for entirely another.
In the first place the name of Swiss bank, moreover not it was like the scandals, its name was not mentioned. Frankly speaking, I cannot explain this popularity of this bank.
In other respects everything is predicted. You look themselves.

Friday, January 14, 2005Google published Zeitgeist - this German word is transferred as the “general intellectual, moral and cultural climate of epoch”. And in fact, being examined back for outgoing yr, it becomes clear - entire epoch ended. Let us try to use the “unique reflection of events in the world”, as search machine presents its report.
Very format sharply is differed from analogous, represented earlier than Lycos, and it more greatly resembles the keywords- reports, since are given not the most popular demands, but those, the frequency of use of which most sharply grew or decreased. Thus, it is analogous, Google represented report about the tendencies, which occurred in the world, which freed from the need for cleaning list, as this makes Lycos.
As a whole the composition of the list “demands, the frequency of use of which most sharply grew” (to approximately so it is possible transfer expression “Top gainers”) it is completely predicted. The interest of people in the events of 11th September and their consequences ensured steady leadership to demands, that relate to the theme of terrorism. True, in the chapter of list demand “nostradamus”, taking into account that this demand, with its entire popularity, nevertheless did not pass into tope00, endurance from which we regularly published, other words, asserts itself the well-defined conclusion that year ago a similar interest practically was not observed completely. The Internet becomes more superstitious.
