From the official Grants.gov daily extract XML on the public endpoint at grants.gov/xml-extract. The extract is federal public record published daily under no licensing restrictions. SleekRank reads the XML URL directly and parses the OpportunityDetail records into individual page-ready rows on each refresh cycle.

Grants.gov publishes the full daily extract every business day, typically in the early morning hours. New postings, status changes, and amendment notices appear within a day of agency submission. Setting cache_duration to 86400 seconds aligns SleekRank's refresh with the Grants.gov daily publication cadence cleanly.

{opportunity-number}-{title-slug} reads well in SERP and stays stable across status transitions (forecasted to posted to archived). The opportunity number is the canonical federal identifier and survives the rename or republication that sometimes happens between forecast and posted phases on a federal grant cycle.

Yes. Both are the two most-searched attributes on federal grant opportunities. Award ceiling renders as the hero stat; close date renders as a countdown component highlighting urgency. Forecasted opportunities show the projected open and close windows in lieu of a hard deadline, with a clear forecasted-status banner.

Closed opportunities still rank for the OpportunityID query because applicants and journalists often look them up after the deadline for retrospective context. Keep the page published with a clear archived banner; the historical record of federal grant activity is part of what makes the corpus useful for ongoing policy research.

Each opportunity carries one or more CFDA (now Assistance Listings) numbers identifying the parent federal assistance program (e.g. 93.396 for NCI Cancer Centers Support).

Yes. Grants.gov publishes a reference table mapping numeric eligibility codes to readable applicant types like "Nonprofits having a 501(c)(3) status" or "State governments". Layer the reference as a secondary data source and join on the eligibility code so the page displays human-readable text instead of opaque numeric strings.

No. Grants.gov covers federal opportunities only. State and local grant catalogs exist on each state's portal with no national bulk standard. A truly comprehensive corpus would need separate page groups per state grants portal.
