What’s a backlink ?

Definition of a hypertext link (also called hyperlink)

A hypertext link is a text in a web page on which you can click to go to another web page.
For example, in the following page http://www.my-website.com, when I click on the “Go to Google” link, I get the page http://www.google.com

This is the source code of the 1st page, … < a href = " http://www.google.com "> go to Google < / a > …

• href contains the url (address) of the targeted web page,
• the text displayed is contained between the tags < a ...> and < /a>

To get the source code of a web page with Internet Explorer, click on Display/Source. Once the source code displayed, to get the hypertexts links with Internet Explorer, click on Edition/Search… A dialog box pops up. Fill it with “a href” then validate.

What is a backlink ?

It’s a hypertext link !!! In Search Engine Optimization (SEO), the backlink term is the same thing (or about) as the term hypertext link in HTML.

When a web page (source) is linking to a second page (destination) of another website, the first one is a backlink for the second one. In the previous example, the web page http://www.my-website.com is a backlink for the web page http://www.google.com.

If 10 web pages link to a web page, this one has 10 backlinks. Adding the number of backlinks of each web page of a website, we get the number of backlinks of the website.

How can I get the backlinks of a web page ?

With Google, to get the number of backlinks of the web page http://www.fedex.com/Tracking, you just need to search link:http://www.fedex.com/Tracking (click here to see the result).
Caution, Google also takes in account the internal links (coming from the same website).

With Yahoo!, to get the number of backlinks of the web page http://www.zlio.com (notice it’s only the homepage), you need to type link:http://www.zlio.com (click here to see the result).
Yahoo! also allows you to get all the backlinks of a website by typing, linkdomain:http://www.zlio.com (click here to get the result). Notice that the number of returned results for the two searches is not the same.

Why should I have backlinks ?

The backlinks make you more visible over the Internet. What’s the point to have a website, when nobody visits it ?

The more you will have backlinks, the more ways to access your website you will open. In other words, the more backlinks you have, the more visitors you get.

The 3 main search engines (Google, Yahoo! and MSN Live) have 85% of the search market over the web.
To determine the rank of a web page for a keyword, they are mostly influenced by the number of backlinks it has. Each backlink is considered as a vote. The more backlinks it has, the most popular it is over the web, the better its rank will be.

Be careful, all the backlinks do not worth the same. Some are more important than others. We will give more details in a further article.

The backlinks with GnoZtiK

The GnoZtiK software provides automaticaly the number of backlinks of all the pages of the Google chart.

The number of backlinks of your web page is shown in the status bar.

In the “Chart” tab of your audits (on the website side), GnoZtiK displays a graphic called “Backlink median”. It shows, for each page of results in Google (from the 1 st to the 10 th ), the mean number of backlinks of the results in the page. A horizontal orange line indicates the number of your backlinks. It is preferable to have this line near the level of the 1 st column (page of the 10 best results in Google).

In the “Url” tab of your audits (on the website side), GnoZtiK provides the number of backlinks of your web page (786 in this example) and between brackets the mean number of backlinks of the whole Google chart (230 in the example). It is recommended to have the number of your backlinks higher than the mean number between brackets.
