From OpenSecrets bulk data plus the FEC individual contributions file. OpenSecrets publishes its bulk data under a license for non-commercial and academic use; for commercial use, license terms are negotiable. The FEC file is federal public record. SleekRank joins them on CRP donor ID for the unified donor-level view.

The FEC publishes individual contribution updates daily during the cycle and weekly off-cycle. OpenSecrets refreshes its bulk profiles monthly. Setting cache_duration to weekly captures most of the meaningful change without overfetching, and any out-of-cycle FEC corrections still flow through within a week of being published.

{normalised-name}-{cycle}-{crp-donor-id} reads well in SERP and stays unique even when two donors share a name. Including the CRP donor ID as a suffix anchors the URL to a specific identity even if the donor's name appears in multiple cycles or in multiple variations across the underlying file.

Yes. donor_type is published as Individual or PAC. Running two SleekRank page groups at /donor/individual/{slug}/ and /donor/pac/{slug}/ lets each template optimize for the audience: individual donors emphasize employer and occupation, PACs emphasize parent organization and political alignment.

Dark money groups by definition do not disclose donors, so they only appear on the recipient side. The donor pages would show donations from disclosed sources to a 501(c)(4); the 501(c)(4) recipient page would be a separate /committee/{slug}/ entry.

Yes. OpenSecrets calculates a party split percentage for each donor based on the share of contributions to Democratic versus Republican committees in the cycle. Render the split as a horizontal bar with color coding so readers see partisan tilt at a glance, with numbers shown beside the bar for transparency.

Each cycle gets its own donor profile in the bulk data and therefore its own SleekRank page. Add a "see other cycles" navigation block that lists the same CRP donor ID across each cycle present in your corpus. Users searching for a donor often want to see the trajectory across cycles, not just a single snapshot in time.

OpenSecrets bulk data is free for non-commercial and academic use. Commercial publishers should negotiate a license with OpenSecrets before running a full-corpus surface. The FEC raw file is federal public record with no license restrictions.
