The seeding playbook broke before August

marketanalyticx.com 7 / 10 05 / Seeding Was Already Dying 25,000 Spam posts caught daily Reddit via Bloomberg, July 2026. Two million inauthentic votes revoked a day. Two agency-run GEO subreddits were banned outright in May 2026. Post as a named brand or not at all marketanalyticx.com

Three reasons not to overreact

marketanalyticx.com 8 / 10 When Not To Act The drop is six days old Promptwatch flags a possible collection artefact. OpenAI has not commented. No citation share number is usable Published estimates run 11.55% to 46.7%. A 4x spread is not a benchmark. Ads and GEO are separate budgets Do not let one story decide both. They answer different questions. Test the ads. Pause the seeding spend. marketanalyticx.com

Do this week

marketanalyticx.com 9 / 10 The Plan Run a $500–1,500 ad test at $20–50 a day Split reporting by subreddit from day one Pause Reddit seeding spend pending data Every figure traces to a named, dated source. Bands marked est. are reasoned, not measured. marketanalyticx.com
