An online shopper can open five competitor tabs in seconds. They compare price, reviews, delivery promise and product-page quality side by side, often on a marketplace where every listing looks the same. That makes e-commerce competition intense, and also unusually transparent: most of what you need to know is public.
1. Find the competitors your shoppers actually see
- Search your top ten product keywords on Google Shopping and in organic results.
- Browse the best-seller lists in your category on Amazon, Flipkart, Etsy or your main marketplace.
- Search your product keywords in the Meta Ad Library to find brands advertising right now.
- Check Similarweb's similar sites for your domain.
- Watch creators reviewing products in your niche on Instagram, YouTube and TikTok.
2. Compare price per unit, not pack price
Two serums at the same price are not equal if one is 30 ml and the other 50 ml. Convert every hero product to price per unit (per 100 ml, per kg, per piece), then include:
- standing discounts and coupon frequency,
- free-shipping threshold,
- cash-on-delivery or buy-now-pay-later fees.
3. Compare social proof
Record ratings and review counts on your site and on marketplaces, the share of reviews with photos, and user-generated content on social media. Review velocity (reviews gained per month) shows momentum better than totals.
4. Map acquisition channels
- Ads: how many active ads each brand runs, which offers and hooks they test, how long ads have run (long-running ads are usually profitable).
- Search: which keywords bring them organic traffic. Use a keyword gap analysis.
- Marketplaces: organic rank for your main keywords, sponsored placements.
- Creators and affiliates: who promotes them.
5. Audit the buying experience
Buy from your top two competitors. Record page speed, product page content, checkout steps, payment options, delivery time, packaging, inserts and follow-up emails. Buying is the fastest way to learn a competitor's retention strategy.
6. Mine reviews for product opportunities
Complaints about size, fit, fragrance, packaging leaks or delivery reveal product and operations opportunities. Use the review analyzer on 30-50 reviews per rival.
7. Score and plan
The e-commerce template weights product quality, price and offers, reviews, acquisition, site experience, delivery and brand. Score everyone, then decide whether to compete on price, brand or a niche.
Common mistakes in e-commerce analysis
- Tracking only well-known rivals while new brands buy ads on your keywords.
- Copying a competitor's discount without margin maths.
- Measuring followers instead of engagement and repeat purchase.
Worked example: a skincare brand
An organic skincare brand compared its hero serum with five rivals. Pack prices looked similar, but price per 10 ml ranged from ₹120 to ₹310. The brand sat at a price index of 118, the upper edge of mid-market. Its rating (4.3) was below the median (4.5), and review mining showed recurring complaints about a pump that leaked in transit.
Actions: fix the packaging (the complaint also appeared in rivals' reviews, so fixing it could become a selling point), add a 15 ml trial size to lower the entry price without discounting the hero product, and test two ad hooks competitors were not using.
E-commerce checklist

- ☐ Rating, review count and reviews per month
- ☐ Active ads per brand in the Meta Ad Library

- ☐ Review themes for each rival
- ☐ Snapshot saved for next month
Frequently asked questions
Should I compete with marketplace sellers or other brands? Both, if shoppers compare you on the marketplace. Analyse the top listings for your main keywords, whoever owns them.
How do I know if a competitor's ads work? Ads that run for many weeks are usually profitable; ads that disappear within days were usually tests that failed.
