How we score, sync, and stay honest.

SMM Supply is an independent index of social-media-marketing panels. We don't sell followers. We measure the providers that do — on catalog depth, sync reliability, delivery guarantees, and integrity — then publish the math so anyone can audit it.

Three rules govern everything below:

• Deterministic math. Every score is reproducible from the inputs we publish on each panel page. No editorial fudge factors.
• Money can't move ranks. Sponsorship is labeled and shown alongside, never blended into trust scores or rankings.
• Open kitchen. If we get it wrong, the correction lands publicly in the changelog with a timestamp.

A 0–100 composite of 10 measurable signals, grouped into four categories. Recomputed on every successful sync. A panel scoring 75+ has, in our measurement, delivered on what it promises across at least 90 days.

Per-panel breakdowns live on each panel page. The signal weights below MUST sum to 100% (we assert this at module load).

Composite scores collapse into four interpretable bands. The thresholds are fixed and shared across every surface — panel cards, compare tables, the Decide engine, and your watchlist.

We pull each panel's public service list on a tiered cadence — 60 minutes for top-50 panels, 6 hours for the long tail. Every snapshot is stored: that's how sparklines, change badges, and the changelog work.

We don't smooth or hide spikes. If a panel cuts their followers price 60% overnight, the chart shows it the next sync. Sync history per panel lives on each panel page under Activity.

When you see "best Instagram followers" or a podium on a category page, the winner is chosen by the Decide engine using the same deterministic math the trust score uses — sorted by your stated priority (cheapest, most trusted, fastest, or balanced). One service per (platform × category × quality tier). Tiers with no qualifying service are omitted, never filled with a placeholder.

We accept paid placements. They are always labeled "Sponsored" — never "Featured", never "Editor's pick", never "Top". Sponsored placements never alter trust scores or table rankings. They appear above tables or in dedicated rails, with the same data shown for organic listings so you can compare directly.

Sponsor rotation is deterministic round-robin keyed to minute-of-hour: every paying sponsor gets the top slot for 60 seconds per cycle. No auction, no opaque bid.

"Verified" means the panel's owner proved control of the domain (DNS TXT) and maintains an active verified subscription. Verified panels receive a small ranking nudge (+2 to +3 points) — never a hard pin, never a score floor.

If a verified subscription lapses, the bright Verified badge is removed and replaced with a neutral "Ownership confirmed" chip until renewal. Verification cannot buy a higher trust score, only signal "real operator stands behind this listing."

• No SMM Supply staff member operates a listed panel.
• We do not accept equity or revenue share from any listed panel.
• Test orders are paid from a SMM Supply account, never gifted.
• If a panel asks us to remove a low score, we won't — but we will re-test if they request it in writing.

File a dispute via /contact. We re-test within 7 days. If we got it wrong, the score updates with a public note in the changelog.

Material changes to the methodology — new signals, weight shifts, threshold moves — land in the public changelog with a dated rationale. Cosmetic edits (typos, clarifications) don't.
