Listing Lab Overview

Listing Lab is where you turn an audit's findings into actual edits. Rewrite your Title, Summary, and Description side-by-side with primary keywords, competitor samples, and listing health rules — then predict your draft's rank against locked competitors before you publish.

When to Use Listing Lab

Open Listing Lab from the sidebar, or jump straight in from a Ranking Audit report. The Lab is always scoped to one audit's target keyword, market, and competitor set, so every signal you see — keyword chips, samples, predicted rank — is directly comparable to what the audit measured.

If you enter from the sidebar, you'll pick which audit to open. If you haven't audited the extension for the keyword yet, run an audit first — Audit and Lab together form Extension Ranker's Ranking Optimizer flow.

Layout

The Lab sits inside a single card with three regions:

• Inner Header at the top shows your optimization context — target keyword, market, the number of competitors locked, and how long ago the audit was taken. The Predict Rank button lives here. Predict anytime — there's no need to fix your Listing Health first.
• Editor body on the left holds three field editors (Title, Summary, Description). The active field is fully editable; the other two render as read-only preview cards you can click to switch into.
• Reference sidebar on the right pairs Listing Health rules with field-scoped keyword guidance and competitor samples.

A Predict Rank Panel appears between header and body once you've predicted at least one rank.

Real-Time Keyword Guidance

The right sidebar's tabs (Title, Summary, Description, Samples) update as you type. For each field you'll see:

• Primary keyword — terms the audit identified as essential for the target keyword. Chips are color-coded by coverage so you instantly see which terms you're using and which are missing.
• From competitors — terms top-ranking competitors lean on. Click any chip to see which competitors use it, how often, and the typical frequency range.
• Custom keywords (Description tab only) — your own additions, useful for brand terms or feature names.

Coverage updates live without delay — usage is computed in the browser via stem-tokenization.

The Samples tab is the inspiration view. It shows the actual Title, Summary, and Description text from your locked competitors so you can study how top-ranking extensions phrase their listings — patterns to adapt for your own copy, not to copy verbatim.

Predict Rank Before You Publish

The Predict Rank button runs your draft through the same model that powers Ranking Audit. The Predict Rank Panel then shows:

• Current rank → Predicted rank against the competitors locked in your audit.
• What drove the change — Listing score before/after, plus delta bars for Title and Content strength (the two factors editing can directly influence).
• Next step — state-aware guidance: publish, build authority, roll back, or keep iterating.

When the draft changes after a prediction, the panel enters a stale state (amber border) reminding you to re-predict. Your draft auto-saves the whole time, so predicting is never destructive — run it as often as your draft evolves.

Listing Health

Listing Health is a flat checklist of binary Chrome Web Store rules — character limits, formatting requirements, presence of required fields. Failing rules surface immediately so you can fix them as you go.

Per-Field Restore and Auto-Save

Each editor's header has a Restore button that resets only that field to its audit-time value. This lets you experiment with one field while keeping confirmed changes in the others.

Drafts auto-save as you type — the Saved indicator in the Inner Header confirms persistence. You can leave the page and pick up exactly where you left off.

Next Steps

After your edits go live in the Chrome Web Store:

• Use Ranking Tracker to monitor how your published changes affect rank over time.
• If your audit is older than a few weeks, consider running a fresh Ranking Audit to re-baseline before another optimization cycle.
