problem with text

Hello,

I create this script ” <script>
jQuery(“._searchresultsblock h4″).after(‘<p> <mark style=”background-color:LightCoral;”> ΟΣΕΣ ΑΓΓΕΛΙΕΣ ΣΤΟ ΛΟΓΑΡΙΑΣΜΟ ΣΑΣ ΕΜΦΑΝΙΖΟΝΤΑΙ ΜΕ ΚΟΚΚΙΝΟ ΕΧΟΥΝ ΛΗΞΕΙ</mark></p>’)
</script> ”
Τhe problem is that this script appears to the search results page and the personal classifieds of any user. I want this text to appear only on personal classifieds each user and not on the page with search results.

Could someone help me;
