Released: August 15, 2025
We’ve expanded the Daily Sync feature for URL and Website Knowledge Hub sources to detect a broader range of update signals. With enhanced detection logic, Bolt AI now identifies content changes from more types of metadata, headers, and structured data—reducing missed updates and keeping your knowledge fresher.
Bolt AI now checks for updates using multiple signals, applied in priority order, starting with the most reliable indicators and falling back to others if needed:
HTTP Headers
ETag: Reindex if different from the previous value
Last-Modified header variations:
last-modified,x-last-modified,x-amz-meta-last-modifiedContent hashes:
x-content-hash,content-md5,x-checksumAWS S3 version:
x-amz-version-id
Sitemap
Fetches sitemap.xml (or sitemaps listed in robots.txt)
Checks the
lastmodvalue for the specific page
HTML Meta Tags
Modified/Updated dates:
article:modified_time,og:updated_time,last-modified,DC.date.modified,dcterms.modified,modified,updated,revisedPublished/Created dates:
article:published_time,og:article:published_time,DC.date,DC.date.created,dcterms.created,date,publish_date,publishdate,pubdate,created
Structured Data
JSON-LD:
dateModified,datePublished,dateCreatedSchema.org microdata:
itemprop="dateModified",itemprop="datePublished"HTML5
<time>tags with datetime attributes
RSS Feed Items (for RSS-sourced content)
Compares the
isoDatefield from RSS feed items against the last indexed date
These improvements make Daily Sync more accurate and reliable by capturing updates from a wider variety of signals. This ensures your knowledge hub content reflects the most recent information with fewer missed changes.
