Prices are read from Polar when this page is built. Every sale shows up on this page, in the revenue figure above, read by the program from Polar.

Hypothesis

A free Chrome extension solving one recurring task for a paying professional audience (sellers, recruiters, agencies) gets found on long-tail store queries and converts to a $8-$15/month licence validated against Polar.

Stop rule

Kill if the Chrome Web Store rejects Indexkeeper twice for a non-fixable reason. Signal = CWS weekly users + Polar licences, clock starts the day the listing is live: under 10 weekly users 14 days listed -> one listing revision; under 20 weekly users 30 days listed, or 0 licence purchases at 200 weekly users -> kill. Submission is ours: no date.

What we tried

a stranger cannot install Indexkeeper today. Blocks: Google API token (an owner step) + Indexkeeper OAuth client (an owner step), both owner; then agent: e2e (1 round) -> upload + submit via the CWS API in the very next round (developer fee paid 31 Oct) -> CWS review. Firefox AMO: build ready (lint 0 errors, 36 tests), Google accepts the allizom.org redirect on the Indexkeeper client (curl of /o/oauth2/v2/auth: sign-in page for the allizom URI, redirect_uri_mismatch for a bogus one).

Next step

agent pace: build 2 (Search Console e2e, an owner step done) now -> CWS upload -> owner dashboard step; pages check A on 7 days of Search Console data (8 Nov); alternative.me in sweep now.
