The eight pain signals, whether each was found, and the points it added

S2Ads into a weak listing The listings tied to paid placements have no weak spot among the rules checked. Clear	Clear	0 of 14

S7Rank momentum Rank moved down between reads Found	Found	11 of 14
S8Listing gaps while advertising 2 kinds of listing gap on an advertised brand Found	Found	6 of 10

Each signal adds its weight, scaled by how severe the finding is: in full for high, three quarters for medium, half for low. A signal that finds nothing adds nothing, and the weights add up to 100. Priority also counts the room there is to help and how fresh the findings are.

08 · Questions

What agencies ask first.

Where does the data come from?

Public pages only: Amazon listings, offers and search results, the Meta Ad Library, Google Ads Transparency and the brand's own website. Nothing private is read, and nothing from a seller's account.

How fresh is a lead?

Every lead shows the day it was last read, and every screenshot shows the day it was taken. A direction, such as rank or the share of 1–2 star ratings, is called only from two reads at least 3 days apart.

How is the pain score worked out?

Eight signals, weighted 12, 14, 16, 14, 12, 8, 14, 10, add up to 100. A signal that finds something adds its weight, scaled by how severe the finding is. A lead shows every signal, what it found and the points it added.

What counts as proof?

A dated screenshot of the public page that shows the finding. A finding without one is not published, and neither is a brand that has no finding we are confident in.

Are the sizes exact?

No. A brand's monthly revenue is an estimate, and a lead says so beside the figure. Treat it as a size band, not a number to quote.

Do I get contact details?

A lead links the people we find for a brand by name, title and public profile, with where we found them. Emails and phone numbers are not part of a lead.

What does the report carry?

Your agency's name and logo, each finding with its screenshot, the listings one by one, and a pitch. Share it as a link and see when it is opened and clicked, or save it as a PDF.

How is this different from a list of brands?

A list gives you names and revenue. A lead gives you the reason to call: the problem, the screenshot that proves it, and the pitch written from it.

What is the inbound audit?

An audit that runs on your own website. A visitor pastes an ASIN and a work email, the audit runs in about a minute under your agency's name, and the lead, with its top issues, comes to you. Ask for a demo to see it.

How do I start?

Request a 7-day trial. We set up your categories, the size of brand and the services you sell, and your first batch follows.

Stop prospecting. Start with the evidence.

Request a 7-day trial and open your first week of leads, or talk to us about the weekly leads and the inbound audit.
