Back Links


The previous chapter was an introduction to link earning a SEO outside where we could talk a little bit backlinks. Now is the time to talk about in more detail links.

Behind the links hides the concept of Google Juice. However, so far we have only to transport the juice in our own pages. We will see that when we speak of the other sites, the Google Juice takes on another dimension. This will also be an opportunity for us to talk about PageRank.
images_434What are backlinks?

Setting a backlink
An inbound link

A backlink is nothing more than an inbound link to your site on the web. This link needs to be done “hard” with the HTML link tag <a>. The address of the website referred must be entered in the href attribute and starts of course with http: //. Already using hyperlinks to circulate the Google Juice on your own website. A backlink is therefore nothing but a hyperlink that Site A is to a site B.

For a link is actually considered a backlink, it should in no case be defined rel = “nofollow”. Indeed, backlinks are used to convey the Google Juice and awareness between the different sites. So there is no point in creating backlinks “clogged”. ^^
What are backlinks?
Good and bad backlink?

The backlinks serve several things, and they are extremely important in your SEO strategy. Here is what a backlink you earn:

Google Juice extra from another site;

reputation and notoriety.

Indeed, as we have seen in the previous chapter, websites have an “image product” to Google. When a site has a backlink from another site, it also enjoys its reputation.

So we can differentiate two types of backlinks. On one hand, there are backlinks earn you a lot of Google Juice, reputation and popularity. These are backlinks that come from sites that have themselves an excellent SEO. On the other hand, there are few backlinks that refer you to Google Juice, little known and little popularity: they are backlinks that come from sites that do not necessarily have a very good SEO or, in any case, which have less good SEO as yours. I assure you, both types are rather positive: so do not spit on the drop of Google Juice you can benefit, even if the juice is from small websites. πŸ˜‰

Note that even though this is not mandatory, it is always best to get better referenced sites backlinks than his. If these sites are increasingly enrolled in the same theme, it’s perfect!
Backlinks to avoid

However, some backlinks should be avoided. Quite simply, there are links from sites that are blacklisted by Google because they do not meet the guideline, or who enjoy a catastrophic reputation on the web. Generally we try to stand far away from these websites.

For your information, we will see in a later chapter directories on the web. Some are on a blacklist, and it will be an opportunity for me to give you an example of bad backlink.
Your goal, web marketing?

images_174Your objective is to collect as Google Juice, popularity and notoriety as possible … by getting more backlinks (quality) possible! For this you’ll need to put in place strategies to encourage other webmasters to create links from their site to yours. It’s not very complicated, but we will have to get started! It is here that generally, the boundary between SEO and web marketing is least felt. It is impossible to separate these two concepts when it comes to creating backlinks campaign (or netlinking).
Netlinking: encourage others to create links
The netlinking
Encourage others to create links

When a website is built correctly and running, all the work of a responsible SEO is to conduct campaigns netlinking. Wondering what it is? This is simply to encourage other webmasters to link to your site. There are many different ways to do this, and I’ll explain a little about how it all works. You will see that there are a lot of vocabulary, you are also not required to retain it by heart.
The link ninja

The link ninja is undoubtedly the most direct and concrete way to ensure that other sites create links to your own pages. Why is that? Just because it is you yourselves who will create your link on other sites. For this you have several options. Take the example of a blog that offers its readers to comment on articles. Nothing too surprising, but let’s see the contact form that such a blog can offer you (below).
A contact form asking for the address of your siteUn contact form asking for the address of your site

It is quite possible that some of these forms ask you the address of your website. It is absolutely not hesitate to inform the URL of your website when you see such comments, as long as the blog is part of the same theme as your website. This can only earn you points in terms of SEO, especially if the site in question is recognized as a quality website by Google.

WordPress blogs consistently offer form asks you to enter your website. You must be aware that, by default, this field is notified rel = “nofollow”. So will not flood all WordPress blogs you know in order to boost your SEO because it will not be used much. However, some WordPress blogs administrators activate the “Website” field “dofollow”. To you to find a list of WordPress blogs … and comment moderately. πŸ˜‰

WordPress comments are almost always subject to moderation before being published. You will need to comment on articles thoughtfully if you want backlinks easily.
User Image

Another tip I can give you is to use the YouTube video uploads. Indeed, the video-sharing site is the third most visited site in the world and rightly belongs to Google. He offers to share the videos that are on your computer or on your smartphone … In addition to this, YouTube allows you to give a description of the contents of your video. In this description, you can create links that will be followed by Googlebot when the visit YouTube. So you have the opportunity to create links from a site that has a strong reputation. These links will earn you a lot of Google Juice.

This advice also applies to Wikipedia, the contents are freely editable by all. However, do not do that when your site really brings something to Wikipedia: do not make the free encyclopedia evil monitoring directory! Knowing also that it is frowned upon to add his own site to Wikipedia, you can delegate this thankless job to a friend. P
The link baiting
User Image

The link baiting is another way to build links to your site across the web. The link baiting is actually based on your content. The key is to get by delivering high quality content that will generate interest among Internet users. Your content should thus have a real added value that incites link to it. Consider the Zero site that has managed to explain to beginners, so very suitable, a subject as complex as programming. You may well advise the Zero Site domain by a backlink to someone who wants to learn programming.

“Link baiting” means “fishing ties.” So you have to actually produce relevant content to encourage webmasters to link to you. To this you can add small options at end of article to share your content. A good idea is to create the opportunity to relay the web page on forums by providing a quick copyable link at the bottom of the article. It’s up to you to build the rest!

I suggest you read this article proposed by It offers 10 examples of successful link baiting. You will see that we can not do much else to offer relevant and intelligent content, and then follow the buzz of the moment. πŸ˜‰

Surely there are many different methods of netlinking there are functions in C, and I can of course not all the detail here … Search on Google and you should find a number of sites that deal and SEO who will explain other methods of netlinking.

images_435You can also imagine your own solutions. How to make to get others to link to my site? You will definitely find yourself the answer to this question.
Hint: PageRank
Measure the confidence index a site
The PageRank

Since the beginning of this part, I have introduced new ideas to own websites: popularity, trust, reputation … When we talk about SEO purely “in-page”, there was no talk of these ideas. With the introduction of backlinks, it is no longer possible to ignore these new concepts.

For Google, a site is not just a set of HTML pages linked together, it is also an ecosystem which has a more or less good image. But this has a real impact on how Google indexes the content. To evaluate the image, reputation and the reputation of a website, Google has developed, in its infancy, it has an index called “PageRank”. This index takes the form of a score from 0 to 10. The higher the score, the higher your site has a good reputation on the web.

PageRank is named after the current Google CEO Larry Page. As we saw in the first chapter of this tutorial, Larry Page is also the co-founder of Google.

The PageRank evolves slowly. When you launch your site, its PageRank is directly set to 0 when the Google index. Over time, and depending on the quality of backlinks you receive, your PageRank tends to rise. But believe me, it does not happen overnight! Here are a few sites PageRank you know.

PageRank is applied to a web page, not a complete website. Two pages of the same site can have two different PageRank. That makes sense, because the sites are nothing but web pages linked.

Get the PageRank of the site

Get the PageRank of the site is very simple, and you have several tools that allow you to access very easily and very quickly. At the beginning of the course, I advised you several extensions for Firefox and Chrome browsers. Many of these extensions allow to obtain the open website PageRank currently in the browser. This is the case of “WebRank Toolbar” in Firefox, and the extension “PageRank status”. Feel free to analyze certain websites that you know to get their PageRank. Web applications also offer you to enter an address to return you the target site PageRank. This is the case for example of

When a web site is too new or not yet indexed by Google, its PageRank can not be defined. So do not worry if you just put your site online for the first time and you see a negative PageRank. πŸ™‚
The PageRank formula

We now know how the PageRank. To bring them up, you must get site backlinks PageRank is high, the ideal is that the PageRank of pages that links to your site are higher than your own PageRank.

For your personal culture, know that PageRank is not a smoky stuff that comes out of nowhere. This is a calculated value through a rather complex scholarly formula developed by Google.

CS (A) = (1-d) + d (PR (T1) / C (T1) + … + PR (Tn) / C (Tn))
The PageRank formula – Source: Webmaster Hub
You know, PageRank is a score of 10 representing the reputation of a website. To see its PageRank increase, you need to get backlinks from pages with higher PageRank than yours. This is the only way to increase visibly.

Backlinks are incoming links to your website.

These are extremely important in your SEO strategy.

images_009You must encourage other webmasters to link to your site, the netlinking.

The foundations of the “Off-page SEO” SEO through directories

The foundations of the “Off-page SEO”

SEO can not be limited to your own site: it will have to work together with others to make your site a well referenced site. See here the ins and outs of SEO outdoors.

Note that this chapter only serve as a general introduction to SEO outdoors. We return in detail in the following chapters.
Introduction to SEO outside
User Image
Work with other sites …
… To boost his own SEO

The web is nothing but a huge pile of websites who are all next to each other. Sometimes these sites are partners, other times they are competitors … Nevertheless, all these sites want a single thing: to be visited. Moreover, we have seen throughout the previous section how to generate visits to your site.

However, SEO goes much further than that. It is certainly well optimize its pages but not only! All we’ll look at this new game, it is the other face of SEO: SEO out of your website! You should now know that if you stay focused on your own site, it will never take off. Your website today can no longer build its ranking on its own potential: it will have to work with other sites.
Google’s mission!

Early in the course, I told you a little bit of the mission that Google had given: making information easily accessible to all. Google therefore refers millions of websites and establish a more relevant list of results possible for the search as you type. All this, you know. What you probably do not know is that Google there is also a relationship between the various web sites that exist in its index …

This relationship makes sense with the notion of hyperlink. Indeed, we have seen about the links in the previous section it was not a simple browsing experience for the user, but a real challenge for SEO. These are your links that feed your web pages in Google Juice. Thus, the more there is of links to a page A, page A will weigh more heavily in the balance when Google will index.

However, we can also create links to other websites, and these websites can also create links to us. All this really means something in the eyes of Google, which create an image of the reputation and the reputation of a site based on the number of incoming links to it and the quality of these links.
Trusted sites and quality
A trusted website is a quality site
SEO “in-page”

It is now high time that I reveal everything we did in the previous part of this course. I learned you build your web sites so SEO-Friendly. But beyond that, I have given you all the keys for you to build websites of trust and quality. These two concepts really mean something to Google. I redo here a very quick summary of what we have seen in the previous part of the tutorial. Site of confidence and quality, for Google is:

List of Google Ranking Factorsa website that offers a lot of content;

a website that offers relevant and interesting content for the Internet;

a site that loads fast;

a website that offers a clean HTML code;

ergonomic site;

a site with a clean tree;

If your website retains all these qualities, it is likely to earn a strong reputation over time, both among Internet users than Google … Take for example the Wikipedia site, which includes a number of these qualities and is part of the best web sites in the world in terms of SEO. If you are interested in the image of Wikipedia, you will notice that it is generally very positive. Note that by “image”, I really mean reputation on the web. You will quickly find that Wikipedia is quoted almost everywhere on the web and it has inbound links everywhere. This should be your major work when referencing you on other sites. Your goal is to maintain the image that your site has with others, while encouraging them to create a maximum of inbound links.
Inbound links
The major feature of SEO outside

We devote their entire chapter, but I would still like to talk here of incoming links or backlinks in English. They are actually vectors SEO outdoors: all will pass by them. You should:

encourage other sites to link to your site;

to ensure that these links are of high quality.

You should know that now almost all occasions are good for ensuring that other sites create links to yours. For a surfer, a link simply means additional ease of access to information. For Google, it goes further. If a site A creates a link to a site B, site B then receives notoriety Site A. The only quality of your pages is not enough to ensure a good SEO, working with others! “. This is the only idea that this very short chapter seeks to present. If you understand that, it’s fine. πŸ˜‰

Note that even when they can be separated into two categories backlinks: good backlinks and bad backlinks. It is therefore necessary to qualify my words when I say that every opportunity will be good to ensure that other sites create links to your site. In the next chapter we will see what a bad backlink. To the extent possible, be avoided to have.
Back on Google history
The Off-page SEO, Google signed a new
Before 1998

Before 1998 and the launch of Google, SEO was done only on your own website. The concepts of link and reputation did not really exist. As you know, we just put the right keywords in the <meta />, and we found ourselves at the top of search results without much problem.
Launch Google

Larry Page and Sergey Brin, the founders of Google, went from a simple observation when they created their search engine: search results that emerged Altavista were not the most relevant. Therefore, a quick scan of the web has enabled them to understand that they had to base their new algorithm on the links on the canvas. Indeed, on the web, links are synonymous with quality. If a site has a link to a site B is that the B site offers relevant content … and if site B is itself a link to a site C is that the site is C a sufficiently interesting site for the site B, which is already recognized as relevant by the A site, make it a link. And so on with a site D.

The two founders of Google have translated this idea by pages indexing algorithm that Google still uses today. No one before Google had had the idea of ​​exploiting the connections made between sites, and use them as an indexing criterion. This is the algorithm that allowed Google to emerge as the leading search engine (see below).
An image that illustrates the indexing algorithm Google.Une picture that illustrates the Google indexing algorithm.

So you understand that having a website worked well SEO point of view is not enough. It must also have incoming links, to give it more weight to Google. Note that once your site is well referenced and will have many backlinks, your links will represent much for Google. It takes time, but once you have become a reference, you have a few small privileges like … to accelerate the growth of small little-known projects. P

SEO “in-page” is used to create a quality site.

Focus on his own website is no longer enough to guarantee a good SEO.

You must ensure that other sites create links to your site.
SEO by directories

If you are interested in a little SEO, which is certainly the case if you are reading this, there is a good chance that you are one day confronted with the notion of “directory”.

images_010We’ll see what the directories and what they do on the web.
SEO by directories

Directories on the web
What are directories?

You most likely held a book in your hands at least once. This is usually a very large book in which are stored information. Can be found in a particular directory information such as phone numbers, addresses, etc.
On the web is a bit like that, one can find directories directories … but we’ll talk about here do not list phone numbers or addresses, but websites!
Directories are themselves websites!

Specifically, the directories are themselves websites. So are websites that list websites. This definition is similar search engines, do not you think? And for good reason! These directories are in fact an alternative to search engines, they are held either by robots or by humans, and it can be interesting to be referenced for several reasons:

you offer users new ways to find your site on the web;

creating direct links to your site.

The second point is without a doubt the most interesting. Indeed, the directories where your site is referenced generally create direct links to it. So you have an opportunity to create backlinks to your site that will always bring a few more Google Juice in your web pages! Some directories are sites that are recognized as high quality by Google, so you also have a chance to improve your reputation on the web. This is an opportunity not to pass up.
How to choose directories

While some directories are recognized as quality sites on the web, it is clear that others are recognized as frankly bad sites by Google, and be honest, this is the case for most directories. So we have to be careful. We’ll see right away the various methods that are available to you to register in directories. Some are blacklisted by Google and it is on these directories you have any interest in not seeing you. For the rest of the directories, you have to sort them according to several criteria:


the type of link created.

Indeed, what we want here is primarily a way to create backlinks to our site. To do this, so we will have to look for quality directories (which have a high PageRank) and create direct links to the sites they reference. Directories that do not meet these criteria are not very interesting for us.
How to find directories?

With Google! You can type just “Web Directory” or other similar Google search to find directories. Seocktail The website also provides a good quality article that contains an interesting list of directories.
Sign on directories
Several different processes

You need to know there are so many methods of registration there are directories. Indeed, almost every book has a different mode of entry … but one can identify two possible types of registration. On the one hand you have the inscriptions are in hand, and on the other automated registrations.
Subscribe to the hand

images_083This method of registration is very simple. It offers a page with a form to register your site. You usually have to learn more information about your site, such as its name or URL. This is the type of information that you will be asked systematically:

name of the website;

URL of the website;

theme of the website.

Some directories will ask you for other information. I’ve seen books that required an estimate of web site traffic or if the proposed advertisements or not. In short, you will see that we can ask you all kinds of information according to the directory where you want to register, and it is rarely like a directory to another! Subsequently, your website will probably analyzed by a team and will be added or not to index the directory.

The inscription “hand” is usually the registration method to choose, for the simple reason that this registration mode gives you control over your SEO by directories. I encourage you to choose preferably directories that allow you to sign in hand.
Register to directories automatically

Other exciting offers that you will encounter for sure on the web offer automated referencing directories. These offers, paid or free, are generally offered by third party websites that are not their own directories. Specifically, you will be asked some information about your site through a form, and therefore, this information will be at a very high number of directories that will add you in principle their index. This type of registration is very attractive for webmasters, for several reasons:

you have the opportunity to be listed on many directories quickly and easily;

many backlinks are created automatically;

this is automated, you make no effort to suggest your site to directories.

This is actually the easy way: you create a lot of links by making a minimal effort. However, this solution should be banned because it is a real problem. Since you have no control over how your site will be added to the index, you are very likely to find yourself on directories that could be blacklisted by Google and can only harm your site’s reputation.

On the other hand, you have no track your SEO. As you know, SEO is built over time and you will not get anything good from scratch by creating 2,000 backlinks. Run away like the plague so such offers!

Be aware that some of these services exist solely to create email addresses databases for resale to commercial enterprises. So attention to spam!
If the DMOZ (Directory Mozilla)!
User Image
What is DMOZ?

You talk about DMOZ is useful because in conversations about SEO, it is not uncommon to hear that name. As you can imagine, is a DMOZ directory. This is in fact the best known of all. DMOZ Directory or Mozilla, is a directory of project launched in 1998 at about the same time as Google. Today DMOZ reference about 5 million worldwide websites. Its index is therefore a huge heritage sites. The directory is maintained by a community of volunteers to analyze all proposed sites and accept them or not in the index. So you can not register your site in DMOZ manually.

If you decide to register your site on DMOZ, know that it is a long process and will inform you DMOZ little about the procedure. To you arm yourself with patience!
A recognition site

DMOZ has a strong reputation. Y be present and be a link to his site can be truly appreciated by Google, which can boost your ranking if your site is in this index. Another advantage is that DMOZ is an open site. Everyone is allowed to re-index the directory. Be on DMOZ also means being present on all sites using the index of DMOZ. Good or bad thing?, You say. To see.
DMOZ it is still essential?

DMOZ, like all other directories, is losing constant speed since the rise of search engines themselves are really essential for over a decade. Indeed, a very small number of users actually use the directories. They are now being used as a source of Google Juice than as a real alternative to search engines. For DMOZ, the quality of the directory leaves for some time greatly to be desired. Indeed, today we can raise several problems:

the index is not updated as frequently as in the past;

the registration process is very (too) long;

many dead links (404), sites accepted in the past no longer exists today;

error categories.

Sites now able to build a very solid SEO without using directories. So do not make a fixette on the idea of ​​being present in many directories. That might be a plus, especially in terms of reputation and Google Juice, but the real challenge of today and tomorrow is to take on the search engines. πŸ˜‰
Google Directory
Yearbook Google removed since 2011

For your personal culture, know that before 2011, Google also offered him his own book called Google Directory and was accessible at This book was in fact nothing but a Google search based on an optimized version of the index of DMOZ. Since summer 2011, this directory was deleted by Google, the company wishing to focus on improving its search engine (see below).
Source: AbondanceSource: Abundance

images_081Directories are sites that reference other sites.

They can be seen as alternatives to search engines, but they are mostly sources of backlinks.

Do you sign on directories with lots of PageRank and create direct links.

Avoid at all costs sites that register automatically to many directories.

DMOZ is an open book; it is maintained by volunteer contributors around the world.
