Definition of SEO
SEO, or Search Engine Optimization, is a set of techniques and strategies designed to optimize a website's visibility in non-paying search engine results. This includes factors such as site content, information architecture, technical performance and the presence of quality inbound links.
Origin of the term SEO
The term SEO stands for "Search Engine Optimization". It emerged with the development of the first search engines in the 90s, gradually becoming one of the core disciplines of the digital marketing.
What is SEO?
Search Engine Optimization, or SEO, is the process of optimizing your website to improve its position in the search results rankings. Unlike paid search (SEA), SEO does not require direct payment to appear in search results. It is an essential practice for increasing the quality and quantity of traffic to a site organically.
The difference between SEO and SEM
SEM (Search Engine Marketing) encompasses both SEO and SEA (Search Engine Advertising). While SEO focuses on improving rankings in organic search results, SEA involves the purchase of advertising space in search results. SEM therefore represents a broader search marketing strategy encompassing all actions aimed at increasing a website's visibility via search engines.
The importance of SEO for websites
SEO is a crucial component for any website wishing to generate significant traffic. It improves a site's visibility in search engine results, which is often synonymous with an increase in qualified traffic.
Search engine visibility
Good Search Engine Optimization (SEO) enables your site to appear among the top search results. This increased visibility significantly increases your chances of being visited by users interested in your services or products.
Targeted traffic acquisition
SEO aims not only to increase traffic, but to attract visitors specifically interested in your content. A well-honed SEO strategy attracts high-quality, targeted traffic that is more likely to convert into customers or leads.
Credibility and user confidence
Appearing at the top of search results often generates a feeling of trust among users. A good position in the results implicitly indicates a certain recognition and authority in your field, which reinforces your brand's credibility.
The main search engines
Search engine presence is essential to any SEO strategy, and knowing which ones dominate the market can effectively shape your SEO efforts.
Google, world leader

Bing and Yahoo, notable alternatives
Although less popular than Google, Bing and Yahoo capture a significant share of users. They operate with their own search algorithms and therefore represent additional platforms on which to improve your visibility.
Other specialized search engines
There are specialized search engines, such as DuckDuckGo, which focuses on user privacy, or Baidu, which dominates the Chinese market. Adapting your SEO to these engines can be beneficial if your target audience is on these platforms.
