Payment evidence: current spend or explicit intent

ProblemAfter each major Meta algorithm update, advertisers often experience sudden drops in audience quality—CPM spikes and CTR decline—but struggle to determine whether the cause is the algorithm itself, audience pool changes, or needed account structure adjustments, leading to long recovery cycles and serious budget waste.

What this evidence does not show yet

To reach Payment-backed we still need:

a first-hand payment statement — either someone naming what they already pay, or 2 more statement(s) with a specific amount they would pay (we have 0)
renewed mentions — the recent trend is below the promotion bar

No first-hand payment statement is on record here, so this page carries no pricing suggestion. A price with no payment evidence behind it is a guess wearing a number.

Scoring summary

Evidence confidence = strength × evidence volume × source diversity × payment × competition × trend × 10. Counts use independent content items; only first-hand pain, current spend, explicit willingness to pay and concrete feature requests affect the score. Repeated posts by one author are discounted. Scoring and status changes follow deterministic rules.

“Payment-backed” means first-hand payment evidence exists in the record. It does not mean the business is worth building. “Fading” is a recency tag shown alongside any evidence level, not a lower level. Read the full methodology.
