Most websites include metadata for recording a date when a publication (such as a blog, article, or a report) is published or updated. You can index this metadata in your collection to display this information in the search results, use it for sorting, or for filtering.
This how-to-guide details standard metadata fields the search.io crawler detects and how you can index date metadata in your collection.
...
A website page might have multiple date metadata fields on it, for example, datePublished, modifiedDate, & lastupdated, etc. The crawler indexes date metadata automatically if the best practices are followed and the correct meta fields are used.
Below are a few examples of the standard meta-fields that our crawler detects and indexes automatically:
Property | Expected Type | Description |
|---|---|---|
| DateTime | When the article was first published. |
| DateTime | When the article was last changed. |
Note: If you do not provide a datetime with a timezone we will parse it as UTC.
Property | Expected Type | Description |
|---|---|---|
| Date or DateTime | The date on which the CreativeWork was created or the item was added to a DataFeed. |
| Date or DateTime | The date on which the CreativeWork was most recently modified or when the item's entry was modified within a DataFeed. |
| Date | Date of first broadcast/publication. |
