Go to configuration (top menu bar)

Go to Custom –> Extraction

Choose XPath from the drop down menu

Then to scrape og:image URLs add the code:

//meta[starts-with(@property, 'og:image')]/@content

//meta[starts-with(@property, ‘og:title’)]/@content

(Please note – be careful copy and pasting the code above, sometimes the ‘ quote marks get changed to curly format, which will prevent the extraction from working).

 

To see your results go to:
“Custom” tab

Then scroll right to see “Extractor 1” and “Extractor 2”

If the column is empty, it should mean that there is nothing declared for that og specification

 

It’s also a good idea to generate all the schema reports.

In the menu at the top of Screaming Frog go to “Configuration > Spider > Extraction ‘tab’ > Structured data ‘box’ >tick all the check boxes, or the ones that correspond to your schema or open graph data format.
