Let's answer the question right away and denmark number for whatsapp then we can go into more detail.
Let's think about it, we have just done the search, the results come in front of us, already from here we understand whether the page will answer my curiosity or not, we click and in a few seconds we decide whether to continue reading or not.
And, of course, if we think we can make an impression by showing all our novel writing skills, the result is "you know what, my Strega Prize is great, now I'm looking for someone who wants to give me information".
So, a rule of common sense: let's treat the first lines of our text as if they were the abstract of a scientific article.

in the first line we write the meta description , because they are the 155 characters that win over the user before entering the page and by finding them at the beginning of the text we have already given the security of being in the right place;
subsequently, through a bullet point , a numbered list or three lines of text, we provide information about what the article contains and what it will solve for us (maybe we'll even get a nice featured snippet );
From that point on, we organize the text with titles relevant to the search intent for that post, without ever going off-topic.
