diciamo che un articolo tipo potrebbe essere questo: ilmioparto . it / parto-cesareo-programmato . html

Come vedi in fondo viene indicata la data che riguarda l'ultima modifica. Mi piacerebbe poter utilizzare il codice:

<time datetime="DATA DI MODIFICA DEL PEZZO" itemprop="dateModified"></time>

all'interno del file default.php di cui ti giro il codice:

@ElaMedia: chiedo umilmente scusa, avevo letto "prezzo" invece di "pezzo", quindi pensavo che bisognasse leggere questa informazione chissà dove...
Invece è "pezzo" inteso come "articolo" o "post". Faccio una prova e ti aggiorno.

Al posto di:

<?php echo JText::sprintf('COM_CONTENT_LAST_UPDATED', JHTML::_('date',$this->item->modified, JText::_('DATE_FORMAT_LC2'))); ?>

metti:

<time datetime="<?php echo JHtml::_('date', $this->item->modified, 'c'); ?>" itemprop="dateModified">
	<?php echo JText::sprintf('COM_CONTENT_LAST_UPDATED', JHtml::_('date', $this->item->modified, JText::_('DATE_FORMAT_LC2'))); ?>
</time>

Fammi sapere se va.

prima di tutto ti ringrazio!

poi ti dico che ho fatto tutto ma sinceramente credo si debba aspettare qualche giorno per vedere se la cosa funziona giusto? In fin dei conti l'obiettivo è quello di mostrare la data di aggiornamento in serp e quindi presumo che per vedere se funziona l'unico modo che abbiamo è aspettare un pò...

ps: io il test tramite https: // developers.google. com /structured-data/testing-tool/ l'ho fatto ma non so se è tutto ok.

a te cosa sembra?

@ElaMedia: penso che ci sia un errore di implementazione di schema . org, però voglio guardare meglio. Mi riferisco a questa pagina: ilmioparto. it/parto-cesareo-programmato .html

ok grazie

Ciao ElaMedia,
ti confermo che manca la marcatura corretta di schema . org . Se guardi il sorgente non tovi ad esempio questo:

itemscope itemtype="http://schema.org/Article

Devi correggere i file php del tema aggiungendo schema . org .

ok quindi al posto di:

<?php echo JText::sprintf('COM_CONTENT_LAST_UPDATED', JHTML::_('date',$this->item->modified, JText::_('DATE_FORMAT_LC2'))); ?>

metto:

<div itemscope itemtype="http: // schema . org /Article"> 
                <time datetime="<?php echo JHtml::_('date', $this->item->modified, 'c'); ?>" itemprop="dateModified">
    <?php echo JText::sprintf('COM_CONTENT_LAST_UPDATED', JHtml::_('date', $this->item->modified, JText::_('DATE_FORMAT_LC2'))); ?>
</time>
                </div>

Giusto così? Oppure il <div itemscope itemtype="http: // schema. org/Article"> lo devo mettere in un'altra posizione del file php?

Grazie

Va sull'elemento che fa iniziare l'articolo, nella parte alta.

Scusa per prima ma ho risposto in fretta perché ho avuto un'emergenza. Il tag lo metterei su:

<div class="article">

Nota che i commenti sono nel div superiore, cioè il div class="com-content", ma fuori dal div class="article". Comunque penso che questo sia il div giusto perché delimita il contenuto che può essere distribuito indipendentemente dal resto della pagina. Pertanto avrai:

<!-- ... quello che viene prima ... -->

<div class="article" itemscope itemtype="http: // schema. org/Article">

<!-- ... quello che viene dopo ... -->

ok perfetto. Grazie! Il tool di google per la verifica dei rich snippet mi dice che è tutto ok.

ps: il resto (immagine ecc...) mi consigli di evidenziarlo tramite gli strumenti per web master di google (sezione evidenziatore di dati)? Ma sono davvero utili in serp questi rich snippet?

Usa schema . org con la marcatura "inline" nel php, come hai fatto per article.
Dopo ti posto un esempio di marcatura per la nostra pagina di prova "parto-cesareo-programmato".

Questo è un esempio sul tuo codice, ma non l'ho testato. Ho incluso schema .org/article con *name *(titolo), *image *e articleBody (testo; l'ho chiuso in un div).

<div class="article" itemscope itemtype="http://schema.org/Article">

ok ottimo grazie. faccio dei test

quindi tu sei per la manualità? come lo giudichi lo strumento evidenziatore di dati all'interno degli Strum. per WebM. di G. A me sembra piuttosto confusionario.

Non uso l'evidenziatore, che penso sia nato per diffondere la marcatura tra i non addetti ai lavori.
Nei template di Joomla usano "microdata" ed è il primo metodo che ho usato, però JSON-LD penso sia migliore.
In ogni caso, una volta che hai inserito i microdata all'interno del template sei a posto, ci devi tornare solo se vuoi modificare i microdata e/o il template.

Ciao,

ho deciso di implementare qualcosa a mano e qualcosa tramite gli Strumenti per Web Master di Google.

ps: ho seguito la tua guida anche per questo mio sito in Joomla 1.5 (finanziamentipergiovani. it / calcolo-partita-iva . html) ma trovo delle difficoltà con lo strumento che testa i Rich Snippet: mi dice "tipo non specificato"

Che ci siano differenze tra le diverse versioni di Joomla?

Grazie

Ciao ElaMedia,
hai centrato il problema: ci sono differenze tra le varie versioni di Joomla!
Posta il php del template in cui vuoi mettere i microdata.
