Microdati per la data di modifica del pezzo

elamedia

diciamo che ho la possibilità di mostrarlo a video come info del pezzo. basta che lo metto in visualizzazione e l'articolo lo mostra. però non riesco a capire come utilizzare questo dato per renderlo dinamico con il rich snippet

fda

Non so quale sistema (estensione, script) usi e quindi mi mantengo sul generico: se il dato viene mostrato in "visualizzazione" significa che puoi risalire a come viene creato, molto probabilmente via javascript o php; a questo punto non devi fare altro che modificare lo script o l'estensione racchiudendo il codice che mostra il dato tra la coppia "time".

elamedia

uso joomla e presumibilmente dovrei inserire questo codice nel file default.php
mi dai una mano a creare questo legame attraverso il codice php?

fda

Dobbiamo vedere il tuo codice, perché non sappiamo al momento come viene archiviata/generata l'informazione sulla data. Dovresti fornirci qualche altra informazione, meglio ancora se posti il php.

Mi spiego: questa informazione non dipende dal core di Joomla, quindi devi per forza avere un'estensione o uno script o qualunque altra cosa che la produce.

elamedia

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:

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.

fda

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.

elamedia

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?

fda

@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

elamedia

ok grazie

fda

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 .

elamedia

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

fda

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

fda

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 ... -->

elamedia

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?

fda

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".

fda

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).

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.

fda

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
