What is webmasters?
A webmaster is someone who creates and manages the content and organization of a website, manages the computer server and technical programming aspects of a website or does both.
In a very large corporation, there may be a webmaster team of people at the top of the corporation who establish the overall corporate site design and policies, arrange the necessary technical resources (working with the people who provide the corporation its network infrastructure), and supervise the design of the corporation’s website (which is often done by an outside firm). At division and product levels, there may be additional webmasters who organize and develop the site content and programming for their division or product. In addition, there is likely to be an interrelated effort to create a site design, organization, and content for the corporation’s intranet.
At a small corporation, the webmaster may be in charge of creating the site and putting it on a separate company’s server or setting up one within the company. The site design and creation may be done initially by an outside design firm that turns the finished site over to the company’s in-house webmaster to maintain and perhaps add content within the established design.
And if you are a firm that specializes in creating Web sites, you may refer to the overall producer or art director as the webmaster for a site.
What is Alexa Ranking?
This is a ranking system set by alexa.com (a subsidiary of amazon.com) that basically audits and makes public the frequency of visits on various Web sites. The algorithm according to which Alexa traffic ranking is calculated, is simple. It is based on the amount of traffic recorded from users that have the Alexa toolbar installed over a period of three months.
This traffic is based on such parameters as reach and page views. The reach refers to the number of Alexa users who visit a particular site in one day. Page view, as its name shows, is the number of times a particular page (URL) is viewed by Alexa users. Alexa.com makes it clear though that, if a particular user visits the same URL multiple times on the same day, all those visits will be counted as one.
The first step of the ranking process is calculating the reach and number of page views for all the sites on the Web on a daily basis. The Alexa ranking is obtained by performing the geometric mean of reach and page views, averaged over a predefined period of time (three months).
