website-designersThe importance of the quality of links in SEO can not be overestimated. Before starting any construction project of links within a web or SEO strategy backlinks, we must be sure that the links will impact not only today, but will continue to have a positive impact in the future.

This means understanding what makes a quality backlink on valuable and why. The elements of a link analysis are:


Link Type
The ‘smell test’

Link Building SEO link building


Relevance is the compass in building links. Not relevant links do not interest us and may even negatively impact our efforts to SEO, they can be penalized by Google, either manually or through Google Penguin update.

Of course, the relevance is not the only factor to be considered valuable, but certainly the first to be examined. And, like all elements of a link, relevance needs to be monitored both at the page level and at the level of dominance.

A page level would always strictly relevant: if the link does not make sense in the context of the page will be useless or worse for our SEO. The relevance of domain basis would also be a target, although there will be times when the link will only be relevant at the page level.

The type of link is the second consideration when a link is analyzed. This means on one hand the ways in which the link is constructed and secondly the manner in which they are linking.

The different ways to build a link are:
Link with anchor text (anchor text). Anchor text is the visible, clickable text of a link. With anchor text links are the most common and the best way to increase ranking in backlinks for a specific keyword, but Google Penguin penalize over-optimization. The words used in the anchor text can be branded with several keywords, semimarca, long tail, etc. The variety is extremely important in building links to organic backlinks.
URL naked. A URL is naked when the full URL is used as anchor text. It is a very natural way to bond, though not as powerful as a link with anchor text.
Link subpoena. Citation links are condensed version of a URL naked, that is, instead of Citation links tend to be more powerful if the address of the website is the same as the brand name (ie, Page One Power and
Image link. An image link is when an image as a link, ie, clicking on the image brings up a new page is used. They are good for the diversity of links if the alt image is properly used (as it acts as an anchor text, albeit a little less powerful).
Short link. Short URL link is a condensed or a shortcut that redirects to a full URL (eg You need to examine these links to see how they are redirected to determine if passing ‘link juice’.
Each of these link building methods have their pluses and minuses, and each method has an impact on the quality of the link. Let us now link the different ways:


Direct. A normal link that leads directly to the desired page. There is nothing that prevents equity link (link juice) or link quality.
Redirection. A funnel is a link that leads to a page, which then leads to another page. This can mean that the link juice is lost if Google’s crawler can not follow the redirect, causing the loss of value of the link to our link building SEO purpose (apart from referral traffic). The links redirect should be checked to see whether they are permanent (301) and temporary (302). 301 pass link juice 302 but spend very little or nothing.
Entire Site (Site-wide). They are links that are in each and every page of the website links. This typically occurs with natural links in the footer or sidebar of a website. This can be natural, and often Google account as a single link. In some cases Google may ‘mark in red’ (especially if it is a pattern), which can bring the wrath of Penguin. 😥
JavaScript. JavaScript is often used to create different types of menus on a website. Often they are friendly from the point of view of search engine optimization, but it depends on how they are coded.
Nofollow. HTML nofollow tag tells the Google crawler to ignore the link. This means that the website owner chooses not to pass link juice. Google suggests using the nofollow tag for paid links or links to sites you do not trust. There are different arguments about whether or not these links have some value, as Google says vagueness about how to treat them. A few links are nofollow very natural link profile of a website.
The goal in building links is to get a natural scheme links: URL links variety naked, subpoena, image and anchor text. Within anchor text links variety variety is essential also: to mix brand terms of relevance, long tail keywords, key words and synonyms accurate.

As the method of linking, try to always seek direct. You are aware of the links ‘across the site’ javascript redirects and because they could potentially ban or harm our efforts in SEO SEO.


The authority is also something that must be measured to determine the link quality. The authority was overvalued in the past mistakenly placed before relevancy.

Today, on building links, link authority is still an important metric. However, if the link is not relevant or is creating an artificial or poor shape, the authority will not be enough to climb in the backlinks of the website.

The authority can be measured in several ways, for example, the PageRank bar tools, but Google’s updated ‘Easter on Fridays’ and is not a measure for it to start.

There is also the Moz toolbar, which includes Domain Authority, Page Authority and mozRank metrics. It is the most convenient tool because it is light, precise and free.

You could also use the Alexa toolbar.

Whether you use to determine the Authority, must be taken into account rather is a quality that a determining factor.

Be sure to check the authority of the site and the domain, as both have an impact on the quality of the link.

Do not rely entirely on the toolbars to determine the quality of a site. They should also check with SEMrush traffic levels, interactions on social networks and blog comments (if any).


The location of the link on the page is the next factor in link analysis. Link location plays an important role as link juice is passed. From best to worst, the locations are:

Within the content
Box content (eg bio box of the author of the article)
Rand Fishkin’s article ‘All Links Are Not Created Equal‘, even though old, is extremely helpful in understanding the principles of building links.

Obviously we do not always have control over the location of the link, but we must bear in mind that affects the overall quality.


The SEO SEO is somehow both an art and a science. When a link is analyzed it is important to look beyond the metrics. The website as a whole needs at least a quick scan quality.

We pay attention to our instincts, it is what we call ‘the smell test’: some websites stink, often before we can determine logically.

This is what we see when we perform this analysis:

  • Other outbound links, both the page and the domain
    Quality of content, both the page and the domain
    Information of the website or brand
    Contact Information
    Date and frequency of blog entries (if blog)

Basically, scan the website with a critical eye: do you have a blog ?, is updated ?, the content is quality ?, page about the business has valuable content ?, you are linking to irrelevant websites ?, It has an address in the contact page ?, and phone ?, who runs the site? What is your training?

All these questions will separate the wheat from the chaff: a real website against a spam website.

The ultimate goal is to have good links that make sense for a positive impact on our efforts in search engine optimization SEO.
