You see the numbers move but not what moved them.
Installs climb or drop, but nothing tells you which change, keyword, or external event caused it.

01 / THE PROBLEM
Chrome Web Store tells you how many installs you got. It never tells you why.
Competitors grow and you cannot see how.
Some extensions in your space are scaling fast. You see the result but have no window into what they did differently.
Every growth decision is a guess.
Without evidence on what is working, you pick a direction on intuition and hope the next update proves you right.
02 / THE GROWTH SYSTEM
Research, improve, and track your Chrome extension in one system.
Research creates the target. Diagnosis creates the priority. Listing Lab creates the change. Monitoring creates the evidence.
01
MARKET RESEARCH
Learn what is happening in your market.
Research any extension's growth, listing history, and keyword opportunities with store and demand data.
02
DECISION
Know what is holding a target keyword back.
Run a Ranking Audit to compare your listing with the current search results and surface the highest-impact fixes first.
03
ACTION
Turn the diagnosis into a listing you can publish.
Rewrite title, summary, and description with live keyword guidance, competitor samples, and a predicted rank before launch.
04
EVIDENCE
Keep watching after the listing changes.
Track ranking history, connect movement to extension updates, and receive an alert when a tracked keyword meaningfully moves.
BUILT FOR EXTENSION BUSINESSES
Run your extension like a business, not just a side project.
When installs, revenue, and market position matter, you need a repeatable way to decide where to invest, not another collection of reports to interpret.
- Protect the search visibility your business depends on.
- Focus limited time on the highest-impact listing decision.
- Keep a measurable feedback loop after every change.
03 / ONE DECISION, PROVEN
StockGlow by Upstox doubled its users in 4 weeks.
“Extension Ranker definitely played a key role in improving the rankings.”
Ronak Agrawal StockGlow by Upstox team
Effectively invisible on its money keywords
The extension had solid fundamentals but was not appearing in Chrome Web Store search results for relevant terms.
Found an underserved keyword
Keyword research revealed that "stock" had strong search demand and a winnable ranking gap.
Rewrote the listing around the keyword
The team used Listing Lab to restructure the title and description, then checked the predicted rank before publishing.
5,000 → 10,000 users in 4 weeks
The extension reached #7 for "stock" and its install base doubled within four weeks.
04 / DEVELOPER PROOF
Built for the people responsible for the result.
Extension developers use the evidence to replace assumed keywords, unclear priorities, and stagnant growth with a next action they can explain.
“Extension Ranker showed me that users were not searching for the keywords I assumed. After adjusting my titles, traffic doubled in two weeks.”

06 / FAQ
Questions an extension business should ask.
How fast will I see results?
Your first audit takes about two minutes and returns a prioritized fix immediately. Ranking evidence then builds daily from your baseline. StockGlow by Upstox doubled its installs from 5,000 to 10,000 within 4 weeks of optimizing its listing, though outcomes depend on your market and competition.
What can I use immediately after signing up?
You can add an extension, research indexed extensions and keywords, establish a ranking baseline, and start an audit. New accounts receive a 14-day Starter trial with no credit card required.
Do I need Chrome Web Store SEO experience?
No. The product translates search data and competitor comparisons into a prioritized diagnosis, so you can start with the next action instead of learning an SEO toolkit first.
How does Predict Rank work?
Predict Rank evaluates your saved Listing Lab draft against the same competitive set captured by its Ranking Audit. It estimates the draft's rank range before you publish it to the store.
