Marketplace Sidekick
Chrome extension · v1.4.0

Score any listing, on the listing.

A sidebar that opens on Amazon, Flipkart and Myntra product pages and tells you what the listing is missing — the score, the checks behind it, and the fixes worth doing first, in order.

Not on the Chrome Web Store yet — review takes a few weeks, and we'd rather you had it now. That means a four-step manual install, and Chrome will show it as an unpacked extension. Free on every plan, including the free one — there is no upgrade gate on it.

What it does

One score, and the reason for every point.

A score you can argue with

Every point traces to a named check with a threshold. Nothing is a black box, and nothing is a language model's opinion.

Fixes in impact order

The panel opens on the three fixes worth doing first. The points each one is worth are measured by re-scoring the listing with that fix applied — not asserted.

Nothing leaves the browser

The listing is read from the page you already have open. There's no upload, no account needed, and no analytics.

Three marketplaces

Each scored on its own rules.

The same checklist on all three would be wrong. Flipkart has no Prime; Amazon has no size run. So each marketplace gets its own weights and its own checks, and anything a site genuinely can't show is left out of the maths rather than counted as a failure.

Amazon

Reads the product page directlyID: ASIN
Images 20%SEO 20%Content 20%Trust 15%Conversion 20%Availability 5%

The only one with a competitor snapshot: it reads the top organic results for your own keywords and shows where you sit on rating, reviews and price.

What it can't do here
  • Backend search terms are seller-only data and are never scored.
  • Verified on amazon.in; .com and .ae are wired up but less tested.

Flipkart

Reads the page's own product data blockID: PID + LID
Images 20%SEO 20%Content 20%Trust 20%Conversion 15%Availability 5%

Detects Rich Product Content — Flipkart's A+ — by its CDN path, so it knows whether you've actually published modules rather than guessing from the layout.

What it can't do here
  • No competitor snapshot: Flipkart's search results have no parser we've verified, and unverified averages are worse than none.
  • Video can't be detected — Flipkart's gallery exposes no reliable marker, so the check is skipped rather than failed.

Myntra

Reads the page's own product data blockID: Style ID → size SKUs
Images 20%SEO 10%Content 15%Trust 20%Conversion 15%Availability 20%

Availability counts four times more than on Amazon, because a fashion style is a size run. A style can read “in stock” while half its sizes are gone — you lose the sale at the size selector, not the price.

What it can't do here
  • No competitor snapshot yet, for the same reason as Flipkart.
  • Thresholds are calibrated on a small sample of live listings and will keep moving.
Install · about two minutes

Four steps, no account.

  1. 01

    Download and unzip

    Unzip it anywhere you'll keep it — Chrome loads the extension from this folder every time it starts, so don't delete it afterwards.

  2. 02

    Open chrome://extensions

    Paste that into the address bar. Turn on Developer mode with the toggle in the top-right corner.

  3. 03

    Load unpacked

    Click Load unpacked and pick the folder you just unzipped — the one with manifest.json directly inside it.

  4. 04

    Open any product page

    The sidebar opens on its own. Close it and a button stays in the bottom-right to bring it back.

Good to know
  • Chrome may warn about extensions in Developer mode each time it starts. That warning is about the install method, not this extension.
  • Updating means downloading the new zip and clicking the reload icon on the extension's card — unpacked extensions don't auto-update.
  • It only runs on Amazon, Flipkart and Myntra product pages. On every other page it does nothing at all.
Tell us where it's wrong

The bugs worth fixing came from people who told us.

A misread price, a check that fires when it shouldn't, a page it can't open — those are the reports that improve this. The extension asks once, after you've used it a few times, and you can always write in directly.
