What it does

  • Reads marketplace search pages for your niche and logs listings with badges, price and type
  • Groups listings into styles and turns them into shopper worded seed keywords
  • Runs each seed through your keyword tool and uses its export button
  • Scores keywords by demand per competing listing and flags brand names
  • Spot checks the best phrases and writes a report with titles to use and traps to avoid

Your approval boundaries

Approval required

These actions always wait for your yes:

  • Logging in to the marketplace and the keyword tool, it never types a password
  • Spending keyword searches past your plan's daily limit

You decide what happens next.

More about this workflow

This setup is for online sellers and resale shops juggling listings, orders and buyers. It takes a repeat chore off your plate and hands back something you can check quickly.

First, it reads marketplace search pages for your niche and logs listings with badges, price and type. Next, it groups listings into styles and turns them into shopper worded seed keywords. Then it runs each seed through your keyword tool and uses its export button. After that, it scores keywords by demand per competing listing and flags brand names. Finally, it spot checks the best phrases and writes a report with titles to use and traps to avoid. It works with your web fetch and spreadsheets, each on its own login with limited access.

You get the prep work done and waiting for you. The agent stops and asks for your yes before logging in to the marketplace and the keyword tool, it never types a password and spending keyword searches past your plan's daily limit, and says plainly if a step cannot be undone.

Run your workflow

Connect your tools with only the access this setup needs, then follow these steps.

Steps

Do these in order. Test on old data before it touches live work.

  1. 1Set up Web fetch. Keep it to public pages, no logged-in sessions.
  2. 2Connect Google Sheets with its own login, not yours. Grant access to the single sheet it needs.
  3. 3Paste the prompt where your harness takes instructions. See the note under the Copy button.
  4. 4Do a dry run on old or test data first. Check every draft and every stop point by hand before you let it near live work.
  5. 5Read its log after the first real run. Only widen access once a week of runs looks clean.

Safeguards and trust score

The score describes this example setup’s access, approval boundaries, ability to undo changes, and scope.

Access18 / 30

Can draft things that send or spend, so it sits close to risky actions.

Human approval30 / 30

Waits for a yes on: logging in to the marketplace and the keyword tool, it never types a password, spending keyword searches past your plan's daily limit.

Undo and logs14 / 20

Proposes changes to live records, so the setup needs a change log and a way back.

Scope18 / 20

Runs on its own login across 2 tools. Fewer connections means a smaller blast radius.

How to raise it

  • Access: Take away its ability to send, post or spend. Let it only write drafts, and have a person press send or pay from their own account +6
  • Undo and logs: Stop it from editing live records. Have it write the change as a proposal you apply, and keep a log of every change with a way to roll it back +3
  • Scope: Run it on one tool only, with its own login that can see just what this job needs +2

Do all of these to reach 91, up from 80.

More ecommerce and resale workflows

  • Resale sales record for the tax year

    Turns a year of secondhand sales across several marketplaces into one tidy record. It splits personal clear outs from trading, totals sales, fees, postage and stock per platform, and compares the trading allowance with your real costs.

  • Store speed tune up with before and after numbers

    Speeds up a live store page with a method: measure a baseline several times, find the real causes, make small reversible changes on a copy, and compare before and after. A second skill checks the buy button and tracking still work before anything goes live.

  • Listing writer

    Writes marketplace listings from your photos and a model number.

  • Profit after fees check

    Tells you what you actually clear on a buy before you buy it.

Other workflows that use the same tools

  • Daily portfolio explainer

    Personal. Reads your stock tracker each day and explains in plain words what happened to each holding and why. It checks your own rules but never tells you to buy or sell.

  • Weekly ops report

    Operations. Writes the Monday numbers summary so you do not build it by hand.

  • Vendor quote compare

    Operations. Lines up quotes from several vendors side by side.
