How to Use the Competition Tab on AliExpress — Saturation Score and Seller Count

A great product in a saturated market is still a bad product for you. If 340 sellers are already listing the same item, you are fighting for scraps — competing on price, paying more per click, and watching margin evaporate.

The Competition tab in the free AliShopping Tools Chrome extension gives you a straight answer on market crowding before you commit. Saturation score, seller count, price range, top-seller concentration — all without leaving the product page.

This tutorial shows how to read it and how to use the signals to pick markets with room to grow.

What the Competition tab does

The Competition tab analyzes how many sellers are listing the same or near-identical product, what price range they span, and how concentrated sales are among the top few. It returns a saturation score from 0 to 100% with a plain-language label: Low, Medium, High, or Saturated.

Low saturation means few active sellers and room for a new entrant. Saturated means the top 5-10 sellers already own most of the orders and a newcomer will have to outspend them on ads to get visibility.

The data comes from the AliShopping Tools backend matching similar listings across AliExpress and clustering them by product fingerprint (title, image, spec). It is not a keyword search — it is a similarity match, so it catches re-listings of the same product under different titles.

How to access it

Step 1 — Install the extension. AliShopping Tools on the Chrome Web Store, free, no account. Extension ID agiaehdeifaihlndhnhcmopjpjijnfap.

Step 2 — Open any AliExpress product page. The sidebar auto-injects on *.aliexpress.com/item/* URLs.

Step 3 — Click the Competition tab. Fourth tab in the panel. Saturation label and score render first; the seller list and price range fill in after the backend finishes clustering similar listings (one to three seconds).

What each signal means

• Saturation score (0-100%): the composite crowding metric. Under 30% = Low, 30-50% = Medium, 50-75% = High, 75%+ = Saturated.
• Saturation label: plain-language version of the score. Use it for fast reads; use the numeric score for fine comparison.
• Seller count: number of active listings the extension matched as the same product.
• Average price: mean retail across matched listings.
• Price range: min and max retail. A wide range means sellers are differentiating on positioning; a narrow range means everyone is racing to the bottom.
• Top-5 share: how much of total orders the top five sellers own. If top-5 share is 70%+, the market is effectively closed to newcomers regardless of the absolute seller count.

Real-world workflow

You shortlisted three products from your morning research session. You open each and check the Competition tab.

Product A — LED strip lights. Saturation 82% (Saturated), 420 sellers, top-5 share 65%, price range $4.99-$24.99. Everyone is selling this. Walk away.

Product B — magnetic knife holder. Saturation 44% (Medium), 85 sellers, top-5 share 41%, price range $12.99-$34.99. Crowded but workable — the wide price range means different sellers are winning on different angles (budget, premium, branded). You can find a niche positioning.

Product C — silicone stretch lid set. Saturation 22% (Low), 28 sellers, top-5 share 38%, price range $6.99-$18.99. Blue ocean-ish. Few sellers, no dominant player, and a wide-enough price range to pick your spot.

You pick C as primary, B as backup, drop A. That call took under three minutes. Cross-check B and C on the Trend tab before you commit — low saturation with declining demand is just an empty market.

Common mistakes

• Avoiding all Medium saturation. Medium is often the sweet spot — enough demand to validate the product, not so much that you are fighting a price war.
• Treating seller count alone as saturation. 500 sellers with a top-5 share of 30% is actually more open than 80 sellers with top-5 share of 75%. Look at both numbers.
• Ignoring the price range. A narrow range (all sellers within $2 of each other) signals commodity dynamics. A wide range signals room for positioning.
• Using competition data in isolation. Low saturation + Declining trend = a market nobody is fighting over for a reason. Always cross-check trend.

FAQ

How does the extension detect "similar" products? The backend clusters listings by image similarity, title tokens, and spec overlap. Minor variations (color, pack size) fall into the same cluster; distinct products (same category, different mechanism) are separated.

Does saturation change over time? Yes. Markets saturate as copycats enter. A product that was 30% saturated three months ago may be 60% today. Always re-check before a big buy.

Is lower saturation always better? Not if demand is zero. Pair a Low saturation read with the Trend tab showing Growing phase. Low saturation + rising demand = your best shot at a blue-ocean win.

Why does the Competition tab sometimes show fewer sellers than an AliExpress search? The similarity clustering is stricter than a keyword search. A search for "LED light" returns thousands of hits, most of which are different products. The tab counts only sellers offering the matched product, not everyone in the broader category.

Can I change the similarity threshold? Not in the current version. The extension uses a single calibrated threshold across all categories for consistency. Future releases may expose this.
