SEA definition: search engine advertising

What is SEA? (Search Engine Advertising)

SEA, an acronym for Search Engine Advertising, refers to advertising on search engines. We also talk about paid SEO. This strategy consists of displaying sponsored ads in search results to appear quickly on specific keywords.

Unlike SEO (natural referencing), which is based on the optimization of the content and technique of a site, SEA works according to a pay-per-click principle. The advertiser pays each time an Internet user clicks on his ad.

SEA is mainly used via advertising platforms such as Google Ads or Microsoft Advertising. These tools allow you to create campaigns, choose keywords and distribute ads to Internet users who are actively looking for a product, service or information.

• generate leads or qualified prospects;
• increase sales on an e-commerce site;

How SEA works

The operation of the SEA is based on an auction system. Advertisers select keywords and indicate the maximum amount they are willing to pay for a click on their ad.

When someone searches on a search engine, an auction is triggered between advertisers targeting that keyword.

Several criteria determine the position of the advertisements:

• the maximum bid defined by the advertiser;
• the relevance of the ad in relation to the query;
• the quality of the landing page;
• the expected click-through rate.

These elements make up what is often called the quality score. A relevant ad can thus obtain a better position even with a lower bid.

Create an SEA campaign

Setting up an SEA campaign generally follows several key steps.

Define objectives

Before launching a campaign, it is essential to determine the marketing objectives: lead generation, online sales, registrations or awareness.

Choose keywords

Keywords allow you to target Internet users' searches. It is important to select relevant queries that are directly linked to the offer proposed.

Create the announcements

Ads must be clear, attractive and tailored to the search intent. They generally include a title, description and call to action.

Optimize the landing page

The page the user lands on after clicking on the ad must be consistent with the ad message and facilitate conversion.

SEA and SEO: two complementary strategies

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

SEO aims to improve the visibility of a site in natural results through the optimization of content, internal networking and technique.

SEA, for its part, consists of paying to display sponsored ads on targeted keywords.

These two levers are often used together in a digital strategy:

• SEA allows you to obtain rapid results;
• SEO allows you to build sustainable traffic over the long term.

Combining SEO and SEA therefore makes it possible to optimize the overall visibility of a site on search engines.
