SEA definition

What is SEA?

The term SEA includes all the techniques and methods used to position advertisements in search engine results, such as Google, Yahoo or Bing.

This practice is part of a global approach to paid referencing to increase the visibility of a website.

The main advantage of SEA is that it enables you to generate qualified traffic quickly, since Internet users are directly exposed to the ads when they carry out a search corresponding to the targeted keywords.

How does SEA work?

The basic principle of SEA, which is achieved by a SEA Agency such as Optimize 360, involves buying advertising space from search engines via their dedicated platforms.

To do this, it is necessary to create an advertising campaign by defining precise objectives, such as increasing the number of visitors to a site or generating conversions.

This campaign includes advertisements, often in text format, which contain keywords that determine their display in search results.

These tools offer an intuitive interface for creating and managing paid search campaigns on their network of partner sites and search results.

Cost per click

The SEA business model is generally based on the cost per click (CPC)This is the amount charged by a search engine each time a visitor clicks on an ad.

This system allows advertisers to pay only for visitors who are interested in their product or service. The amount of the CPC varies according to a number of criteria, including the popularity of the keywords used, the quality of the advert and the competition in the sector.

Implementing an effective SEA strategy

  4. Monitor and adjust the performance of your campaigns SEA: it is essential to monitor the results of your SEA campaigns on a regular basis and to modify certain parameters, such as bids or keywords, if necessary, to improve their effectiveness.

SEA vs SEO: two complementary approaches

Although they are often contrasted, ATS and SEO (natural referencing) are in fact two referencing levers that can be perfectly combined.

SEA allows you to quickly obtain paid visibility among Internet users, while SEO is based on in-depth work on the content and structure of a website to improve its positioning in search engine results over the long term.
