Hello @lucilafreire,
We viewed the source of https://sustentabilidadenoar.com.br/ and the meta description is shown as:
<meta name=”description” content=”Sustentabilidade no Ar é um canal de comunica??o colaborativo que visa difudir notícias positivas sobre sustentabilidade.” />
This matches what you have entered as the meta description in the Yoast SEO plugin; that also means our plugin is working as expected.
While Google typically uses the meta description from the metadata for indexing, this is not always the case. The meta description you enter in our snippet preview are suggestions for Google. Google’s goal is to best represent and describe each result. They use a number of different sources to get this information. In doing so, they try to make the search results as relevant as possible. Due to this being handled on Google’s end, there is little you can do to force Google to display your preferred description.
Using the URL Inspection Tool can sometimes force Google to update its index. You can also reach out to Google Search Console in the forums and ask for further assistance. You can also learn more here
