You attend to promotion of the site? You wish to know, how your project among millions other pages looks? You are interested what to be constant in a rate of rating positions of the site in relation to competitors? It is necessary for you to glance forward and though a little to predict dynamics of development of a site?
If the answer positive all that from you is required it is simple to take and come on alexa.com!
In the given article we will tell about basic possibilities Alexa.com and we will explain some terms which call quite clear difficulties, at those who is weakly familiar with English seo-terminology.
Let's begin, perhaps, with the small historical review.
So left, that being mega-useful service, alexa.com about this day practically has no competitors - such state of affairs was promoted by a number of circumstances, but the main cause consists that is received to collect statistical data of such big scale only to such companies which are entirely integrated into personal computers of regular customers of the Internet.
Let's give an example.
You sometime scanned just established Windows an antiespionage aaplet under name Adaware? If yes, should notice, that unique "the espionage program" which was found out by this scanner, there was a small module integrated into browser Internet Explorer is and there is a part alexa.com by your car. Alexa.com officially asserts, that all data undertake exclusively from, so-called alexa toolbar, but most likely, this source delivers only a certain share of statistics. The basic part of the information is extracted by means of close communications with popular products from Microsoft (and, certainly, other manufacturers - for example, gugla).
Alexa.com It has been created in 1996 by two American engineers - Bruce Gilliatom (Bruce Gilliat) and Brjusterom Calais (Brewster Kahle). Last, among all other, now is one of directors Electronic Frontier Foundation - noncommercial human rights organisation which watches observance of the civil rights of Internet users. • At the beginning of the activity company Alexa.com had the direct relation to creation Wayback Machine (Time machine). Wayback Machine is an Internet archive which collects all data ever appearing in a network. By means of this piece it is possible to look, as this or that site 5 or looked 10 years ago. In 20-30 years the information from this database will use extreme popularity. The archive site is here:
Besides various projects, Alexa actively developed special toolbar - having established it on the browser, the user received advices about where to be directed further from this or that page. These data undertook from the user community which was at all times the generator of sample behaviour. alexa toolbar did and more one thing - showed a context of a visited site i.e. where it is registered, how much on him is present pages, quantity of entering links and frequency of updating.
In 1999, company Alexa has been purchased by corporation Amazon.com - the price of transaction was certain in shares Amazona and was equaled to 250 million dollars. In spite of the fact that Alexa is component Amazon.com, nevertheless, outwardly, service has saved the brendovuju independence and by many users is perceived, as something independent.
From the middle of 2002 Alexa has entered into a close contact with Guglom - guglja granted the search data for services from Alexa.com. Short time, Alexa used also powers Windows Live Search, but in the end of 2006 engineers of the company had been developed own search platform. • Among products company Alexa it is possible to allocate such popular services: • - Alexa Image Search • - The search engine • - Granting of the information on sites. On the last product we also will stop the attention.
So.
In system there is a terminology and if in it to be guided questions to arise should not.
To work it is necessary basically with three terms. Here they:
1. Reach for yoursite.com
In this case attendance of a site is meant - it can or grow or, on the contrary - to fall. Attendance level in algorithm alexa.com is calculated on the basis of a percentage scale - all users who grant the information in a database alexa undertake general unit. Attendance is expressed in percentage of one million users. For example, the site yahoo.com is visited 28 % is means, that from one million serferov, 280 000 visit yahoo.com.
2. Traffic Rank for yoursite.com
The filtration of "a traffic rank" saport Alexs explains thus: • - The trimensual period undertakes a basis; • - Data about attendance of all sites of the Internet from users who have established by the car alexa toolbar undertake; • - From this information the quantity of the seen pages on these sites is calculated; • - From the received data sample on particularly required site is made; • - Data are averaged in conformity by criteria of quantity of visitings and quantity of viewing of pages; Thus, the Site Rank (Traffic Rank) is a position of this or that resource among other sites. Certainly, it is not necessary to forget that these data are average significance (average). Calculation of changes in the Rank is made by the comparative analysis - at present resource position is compared to that rank which has been fixed three months ago.
3. Page Views per user for yoursite.com
This report shows, whether is enlarged or the quantity of the seen pages on separately taken site decreases. For a basis seen by it the unique visitor and a number of pages undertakes one unique visiting (days). Data from all users the average digit is summarised and received. Basically, this technology is very well realised in algorithm Google Analytics - therefore it is recommended to use and this service since there there are more than statistical data (certainly, competitors you there cannot see - only the site). Do not forget, that alexa.com at data processing from section Page Views per user uses 3 month period and, the following report will already make a start from data of the previous.
In spite of the fact that many brand Alexa.com for rather approximate generalisations of attendance of the set resources, nevertheless, this service is very evident and by degrees becomes more and more exact. It is promoted not only growing quantity of users which are delivered by data on a server, but also by improvement of algorithms of account which are announced recently rather often.
The main minus of system consists that alexa toolbar works only with Internet Explorer and users of other browsers, remain out of sight of system. There are and more other restrictions. For example, on the protected pages (i.e. on pages which work under the protocol https) the instrument from aleksy will not work (however, it and is clear - on that they and protected!). Besides all it it is necessary to remember also that fact, that users live in the different countries and if they use alexa toolbar cultural, language and geographical factors can influence hardly their activity in what or Internet sector.
