In their words

How do I identify if this is a traffic problem vs conversion problem?

I have 100 listings I hate when they make these great changes and now I need to manually update each one to take advantage

I am having a problem with optimizing my tracking and potentially make it as automated as possible.

The tools that already cover it

• EstateSales.net: Free email alerts by area (over 90% of users pick a day-before email); FAQ names a keyword 'Treasure Tracker'; has an item marketplace with a Music & Art category; no text alerts or photo reading found.
• Invaluable Dealer Alerts: 500 keyword or artist alerts as a daily email on upcoming auction lots; no estate sale listings, no text messages, no profit ranking.
• The Pickers Map: Treasure Alerts for new sales in an area and follow-a-company; tiny (3 ratings); no item-level want-list matching seen.
• Curio (antique identifier app): Names and values one photographed item at a time (16 061 ratings); does not watch sales or send alerts.
• Valuable Pro: Tool for estate sale pros and dealers to identify, price and list items; not a buyer-side alert feed.
• LiveAuctioneers and AuctionZip: Auction lots only, not estate sale photos.
• PropStream: Built for real estate investors with 20 lead lists; probate is not named on the pricing page and it lists houses, not belongings.
• PropertyRadar: Real estate leads with a probate play; no item contents or dealer want-lists.
• Tactical Arbitrage (Seller 365): Finds Amazon resale deals from 1 400+ retailer sites, not estate or antique stock.
• Vendoo: Cross-listing after you buy, not finding what to buy.

How it was challenged

• The whole demand case is one pitch post in r/WeirdStartups with 1 upvote and 0 comments; the $75 a month claim has no buyer behind it, only the poster.
• The cluster's 28.6% explicit willingness-to-pay share (14 of 49 posts) comes from unrelated posts such as a roofer seeking a loan, not dealers.
• EstateSales.net bars bots collecting its data for any use and commercial reuse without written consent; a block or a cease-and-desist letter ends the product.
• Free incumbents cover the core: EstateSales.net sends free alerts and its FAQ names a keyword 'Treasure Tracker'; The Pickers Map offers free Treasure Alerts.
• Accuracy is the product: spotting one amp model in cluttered sale photos will miss or false-alarm, each costing trust, and there is no accuracy data yet.

The pain point it solves: Marketplace Listing Upkeep

Sellers struggle to efficiently create, maintain, and optimize product listings across multiple marketplaces, leading to lost sales, wasted time, and algorithmic penalties.

Why those fall short

• ads expensive, listings get little exposure, AI and mass-produced items flood search
• no automated measurement capture or listing entry
• support tools cannot differentiate previously active from historically inactive listings
• notifications still appear in app despite being turned off
• Blocking and reporting do not filter or remove fakes
