How Mindber calculates Activity Signals
Activity Signals summarize linked public engagement evidence for a product. They do not assess product quality, company financial health, legal standing, or operational status.
Version v1.5Updated English methodology is controlling.
Scope
Mindber uses Activity Signals to show whether a product has recent public engagement evidence. The score is descriptive, not evaluative. A low or missing score must never be read as a claim that a company is closed, unsafe, unhealthy, or no longer serving customers.
Signals and weights
Each available signal is normalized to a 0-10 signal score, then multiplied by the current model weight. The weighted result is displayed as a 0-100 Activity Score™ when enough linked public signals exist.
- Public traffic trend
- Source: Public traffic-intelligence providers and observed rank movement.
Calculation: Monthly visitor estimate, rank movement, and 30-day change are normalized to a 0-10 signal score. Large short-term drops are dampened when the underlying source confidence is low. - 30%
- Public social updates
- Source: Linked public LinkedIn, YouTube, and X profiles when available.
Calculation: Days since the latest public post, recent posting cadence, and channel coverage are normalized to 0-10. Missing social profiles do not create a negative score by themselves. - 20%
- Hiring and careers signals
- Source: Public careers pages and supported ATS endpoints such as Greenhouse and Lever.
Calculation: Open role count, recent role changes, and careers-page reachability are normalized to 0-10. No detected job posts is treated as neutral unless other public evidence also shows low recent activity. - 15%
- Homepage reachability and changes
- Source: The product homepage and linked canonical domain.
Calculation: HTTP reachability, TLS status, title changes, and content-hash changes are normalized to 0-10. Temporary network failures are retried before they affect the public signal. - 15%
- DNS availability
- Source: Public DNS records for the canonical domain.
Calculation: A, MX, and NS resolution are converted into a 0-10 infrastructure availability signal. DNS is a support signal only; it is never used alone to judge product quality or company status. - 10%
- Pricing-page updates
- Source: Public pricing, plans, billing, and upgrade pages linked from the product site.
Calculation: Pricing page reachability, detected plan/price changes, and recency of changes are normalized to 0-10. A product without a public pricing page is not penalized unless pricing is expected for that category. - 10%
Calculation
The public Activity Score™ is rounded to one decimal place after normalization, weighting, recency decay, and confidence checks.
availableSignals = linked public signals with valid observations if availableSignals.length === 0: status = "insufficient_data" score = null activityScoreRaw = sum(normalize(signal, 0, 10) * weight) activityScore = round(activityScoreRaw * recencyDecay(14 days), 1)
The score uses evidence that is visible from outside the vendor. Private revenue, customer retention, support quality, uptime, security posture, and internal product roadmaps are outside this calculation.
Insufficient data
When a product has zero linked public signals, Mindber returns status: "insufficient_data" and score: null. Product pages must show a neutral "Insufficient data" card instead of a colored gauge, percentile, negative label, or implied judgment.
Check cadence
- High-traffic products
- Every 24 hours
- Mid-traffic products
- Every 7 days
- Long-tail products
- Every 30 days
- Recently claimed or corrected products
- Immediate re-check after review
Public labels
Mindber uses neutral engagement-frequency labels. It does not use pejorative inactivity labels in public product UI.
- Insufficient data
- No linked public signals were available. Mindber shows no score, no red gauge, and no negative label.
- Active
- Public engagement signals are updating normally compared with similar tools.
- Below category average
- Public engagement frequency is lower than comparable tools in the same category.
- Low recent activity
- Multiple public engagement signals show fewer recent updates than usual.
- Reduced update frequency
- Sparse recent public engagement signals across most channels.
- No detected updates (180d+)
- No linked public engagement signal changed for at least 180 days.
Claims and corrections
Product owners can claim a profile from the product page, verify ownership with a company email domain, and submit proposed edits for review. Anyone can also report an inaccuracy.
Limits and disclaimer
Activity Signals are public engagement evidence only. They do not evaluate product quality, user satisfaction, security, company finances, legal risk, staffing level, roadmap quality, or whether the vendor is currently accepting new customers. Scores can lag reality between checks.
