Content generation by utm, how to implement?

Question

CMS

There is a landing page (I don't use cms) that uses utm in the following format:
site.ru/?utm_term={keyword}
{keyword} - random keyword.
There are over 60 items on this page. Loading such a page takes a certain time, which is not good.
It is necessary that the content be loaded on this page, depending on what keyword it uses and this content is displayed on the page.
Is there a way to do this or is there a ready-made solution?

Answer 1

well, filter the output products by the presence of this word in them, if any.
or make a set of products for each key static.
To say nothing more, the code is self-written.
incompatible things

Answer 2

switch($_REQUEST['utm_term']) {
    case 'keyword1':
        // контент при ?utm_term=keyword1
        break;
    case 'keyword2':
        // контент при ?utm_term=keyword2
        break;
}

If you have a selection from the database - form a filter in switch, if just html blocks - delimit their output
