The World Wide Web without links is impossible, unthinkable. The links connect the Web together. The link is the cornerstone of the Web. That is why everything related to links is important: the URL, the linked text, the location of links, number of links and the quality of links.
Links tell us a lot about Web sites and the information they provide is so powerful that it has empowered a whole industry measured in billions of dollars. The hyperlink has made people millionaires and billionaires. Every webmaster thinks about links in one way or the other: where to place them on their Web sites, how to get others to links to them and how to write them.
On the Web sites we recently studied there are on average more than 100 links per Web page and 74 unique links. The average length of text of links is less than two words, 1.82, and 12.54 characters. The average number of unique internal links is 50.62 and 23.87 unique external links. The maximum number of unique links on one page was 1184. Think about it. Now, that is a large number of links.
