I’ve put together a spreadsheet for SEO schema checks here:
https://docs.google.com/spreadsheets/d/1dDqJ9_qrTVoJOZRxieJDp9XE3Q1TCq4ixNVudVtgp2M/edit#gid=0
Use https://classyschema.org/Visualisation and import a URL – test using different URLs, especially for eCommerce websites – like homepage, about page, product page, category pages
Test also with:
https://search.google.com/test/rich-results – add any issues in column C of sheet
and
https://validator.schema.org/ – add issues in Column D
- Put your “to do” list in columns E and F
When using validator, make sure you’re schema has all the relevant parameters.
The separate sheets on the Google Sheet linked above, has some examples for you to check against – written in JSON-LD
Finally, if the site is already live, check the schema reports in Search Console for any errors
