Natural referencing is essential to ensure the visibility of your website.

To do this, it is important to understand the SEO environment and the different elements that make it up.

Moz is one of those essential tools you need to know about. In this article, we offer you a complete definition of Moz and a presentation of its main functions.



Definition of Moz

Moz is an online platform dedicated to search engine optimisation (SEO).

It was created in 2004 by Rand Fishkin and Gillian Muessig under the name SEOmoz.

The company now offers software, tools and resources to help digital marketing professionals improve their SEO strategy.

Moz stands out for its active community of experts and users, who share their knowledge and advice to help you better understand the world of SEO.

How Moz works

Moz offers a range of free and paid tools for analysing and optimising various aspects of a website's SEO.

These tools are based on various metrics and data collected from search engines or other external sources. Here are some of the main features offered by the platform:

Keyword Explorer tool

The tool Keyword Explorer makes it easier to research and analyse keywords, an essential element of natural referencing.

Simply enter a keyword or a phrase to obtain a range of information such as the search volume monthly, the level of difficulty in positioning yourself on this keyword, potential organic clicks, etc.

This tool can also suggest similar or complementary keywords to refine your SEO strategy.

Site Explorer

Le Site Explorer is an analysis tool that can be used to screen a website and identify its strengths and weaknesses in terms of SEO.

It provides information on the site's overall performance, its inbound and outbound link profile and its ranking in search results.


MozBar is an extension for web browsers (Chrome only) that provides quick access to various SEO data directly from the toolbar. The information displayed by this toolbar includes :

    • Referencing metrics for the site visited (Domain AuthorityPage Authority)
    • The number of inbound and outbound links
    • The meta tagsthe page title and description
    • On-page optimisation suggestions.

On-Page and Link Building tools

Moz also offers a number of tools for optimising page content and boosting a site's presence on the web by obtaining inbound links:

    • The On-Page Optimization tool provides recommendations for improving the content of a page based on a chosen keyword.
    • Le Link Building Tool to identify backlinks of its competitors and identify new opportunities for obtaining links to its own site.

Domain Authority and Page Authority: Moz's emblematic metrics

Moz is particularly well known for having developed two specific metrics: the Domain Authority (DA) and the Page Authority (PA).

These indicators are designed to assess the 'strength' of a domain or page in terms of natural referencing. They are based on several criteria, such as the quality and number of incoming links, the age of the domain and the overall quality of the site.

DA and PA are expressed as scores ranging from 0 to 100. The higher the score, the better the site or page is considered to be in terms of SEO.

It should be noted, however, that these metrics do not come from Google and are therefore not necessarily a perfect reflection of reality. However, they are still useful for getting a quick idea of the quality of a site or page.

Some examples of how Moz is used

To better understand the usefulness and interest of the Moz platform, here are a few concrete examples of the application of its tools:

  1. Identification of relevant keywords. By using Keyword Explorer, a digital marketing professional can identify the search terms on which his site has a chance of ranking. This will enable them to adjust their editorial strategy accordingly.
  2. SEO audit a site. Thanks to Site Explorer and MozBar, you can carry out a complete audit of your website to identify weak points and areas for improvement in terms of natural referencing.
  3. Competitive analysis. By comparing DA and PA metrics, an advertiser can quickly get an idea of the overall quality of their competitors' SEO profile. Link building tools can also help to identify competitors' tactics for obtaining inbound links.
  4. Improving visibility through inbound links. Moz offers a number of resources and tips for finding new backlink opportunities and boosting your natural referencing.

Moz: a valuable tool for SEO professionals

Taken together, the features and metrics developed by Moz are an invaluable aid for SEO professionals looking to optimise the natural referencing of their website.

However, it's worth bearing in mind that the SEO landscape is constantly evolving, so it's important to keep abreast of the latest trends and updates to avoid being caught out.
