SEO Definition: Search Engine Optimization

What is SEO? (Search Engine Optimization)

SEO, an acronym for Search Engine Optimization, refers to all the techniques aimed at improving the visibility of a website in the natural results of search engines like Google. In French, we talk about natural referencing.

The objective of SEO is to position the pages of a site on relevant queries in order to attract qualified traffic without paying for each click, unlike online advertising.

Natural referencing is based on several optimizations linked to the content, the technical structure of the site and its popularity on the web.

SEO in digital marketing

In a digital marketing strategy, SEO is an essential acquisition lever. It allows you to capture Internet users who are actively looking for information, a product or a service on search engines.

By positioning itself on the right keywords, a business can generate a regular flow of qualified visitors to its website.

• attract qualified traffic to a site;
• increase the visibility of a brand on the internet;
• generate leads and sales;
• improve the credibility of a business online.

SEO is often part of an overall acquisition strategy that also includes content marketing, social networks and paid search.

Why SEO is important

Natural referencing represents a sustainable source of traffic for websites. Unlike paid advertising, the results obtained through SEO can generate visits for a long time.

• obtain lasting visibility on search engines;
• reduce dependence on advertising campaigns;
• attract an audience genuinely interested in the content;
• strengthen the authority and credibility of a website.

A well-optimized site can thus become a constant source of traffic and potential customers.

How SEO works

Search engines use robots to crawl web pages, analyze their content and index them in their databases. Then, algorithms classify the pages according to numerous criteria in order to offer the most relevant results to Internet users.

To appear in the top results, a site must send quality signals to search engines.

• offer relevant and useful content;
• structure the pages correctly;
• provide a good user experience;
• be cited by other websites.

All of these optimizations help to improve the positioning of pages in search results.

The pillars of SEO: technical, on-page and off-page

Natural referencing is generally based on three major complementary pillars.

Technical SEO

Technical SEO concerns the technical aspects of the site that make it easier for search engines to crawl and index it. This includes loading speed, site structure, HTML tags and even mobile optimization.

On-page SEO

On-page SEO corresponds to all optimizations carried out directly on the pages of a site. These include the choice of keywords, the structure of titles, the quality of content and the internal linking between pages.

Off-page SEO

Off-page SEO brings together actions carried out outside the site to improve its popularity, in particular obtaining backlinks from other websites.

These three pillars work together to boost a site’s visibility in search engines.

Difference between SEO and SEA

SEO and SEA are two different approaches to search engine optimization.

SEO corresponds to natural referencing and is based on the optimization of the site and content in order to obtain positions in organic results.

SEA, or paid referencing, consists of placing sponsored ads on search engines by generally paying for each click on an ad.

These two strategies are often complementary in a digital acquisition strategy.

White hat SEO and Black hat SEO

In the field of natural referencing, we often distinguish two opposing approaches: white hat SEO and black hat SEO.

White hat SEO

White hat SEO brings together techniques that respect search engine recommendations. The objective is to improve SEO by offering quality content and an optimal user experience.

• creation of useful and original content;
• technical optimization of the site;
• natural acquisition of external links.

Black hat SEO

Black hat SEO corresponds to techniques aimed at manipulating search engines to quickly obtain better positions.

• keyword stuffing;
• artificial link networks;
• duplicate or low quality content.

These practices can result in penalties from search engines and harm the visibility of a site in the long term.
