WTNMarket sitemap lastmod governance for real updates
Keep WTNMarket sitemap lastmod values tied to meaningful page edits rather than automated rebuild times. This guide treats WTN Market and WTNMarket search terms as research labels, not as proof that a destination is official or safe.
Define a meaningful update
A revised explanation, corrected fact, new source or changed public status can justify a new lastmod value. Reformatting code without changing visible content usually does not.
Write this rule into the publishing workflow so dates remain consistent across releases.
Use page-level dates
Different WTNMarket articles change at different times. Avoid assigning today to every sitemap entry when only one page was edited.
The visible review date, Article dateModified and sitemap lastmod should describe the same editorial event.
Prevent future drift
Generate sitemap values from content metadata or a maintained change record. Add an audit that compares the number of canonical pages with the number of sitemap locations.
Fail the release if an indexable canonical is missing or a noncanonical URL appears.
Monitor search-engine processing
Bing and Google can choose how much weight to give lastmod. Accurate dates build a reliable signal; inflated dates make change detection less useful.
Use webmaster reports to diagnose crawling, not to justify artificial timestamp changes.
Frequently asked questions
Should lastmod change on every deployment?
No. It should change when the page content or public status changes meaningfully.
Should visible dates and sitemap dates agree?
They should refer to the same editorial update whenever both are presented.
