Google Analytics vs Google Search Console for eCommerce: What to Use, When, and Why

Google Analytics 4 (GA4)

GA4 captures user interactions (events) on your site and ties them to sessions and conversions. With proper eCommerce events configured, you can track product views, add-to-cart, begin checkout, purchases, revenue, and refunds.

Key eCommerce metrics in GA4

• Revenue, transactions, AOV, conversion rate
• Product views → add-to-cart → checkout → purchase funnel
• Source/medium & campaign performance (UTM, Google Ads linking)
• Engagement rate, scroll, video interactions, search on site
• Cross-device and audience insights (with consent)

Pair GA4 with Google Tag Manager for robust event tracking and with BigQuery for granular product analytics.

Google Search Console (GSC)

GSC shows how Google Search discovers, crawls, and ranks your site. You’ll monitor query performance, CTR, average position, and technical SEO issues that affect index coverage and rich results (e.g., Product snippets).

Key eCommerce signals in GSC

• Queries → impressions, clicks, CTR, average position
• Page & country/device filters for SEO measurement
• Index Coverage, sitemaps, canonicalization issues
• Enhancements: Product structured data, Core Web Vitals
• Manual actions, security issues, crawl anomalies

Use the URL Inspection tool to debug specific product pages and ensure the canonical, schema, and mobile rendering are correct.

Questions GA4 Answers

• Which categories and products drive the most revenue & margin?
• Where do users drop off: product → cart → checkout?
• Which traffic sources convert (organic, paid, email, social)?
• What’s the AOV by channel, campaign, device?
• Which campaigns assist conversions (attribution)?

Questions GSC Answers

• Which queries show our products and how often?
• Why is this category not getting impressions?
• Which product pages earn high impressions but low CTR?
• Are Product rich results firing correctly?
• Which URLs are excluded from the index and why?

GA4 eCommerce Setup (must-do)

• Install GA4 via Google Tag Manager. Verify duplicate tags aren’t firing.
• Implement required eCommerce events: view_item_list, select_item, view_item, add_to_cart, begin_checkout, add_payment_info, purchase.
• Pass product parameters consistently: item_id (SKU), item_name, item_category, price, currency, quantity.
• Enable Enhanced Conversions or server-side tagging if possible to mitigate consent/ad-block loss.
• Link Google Ads and set consistent UTM conventions (source/medium/campaign).
• Set time zone & currency correctly; exclude internal traffic; define key conversions.

Broken or inconsistent item_id values are the #1 reason product reports are unusable later.

GSC Setup (must-do)

• Verify Domain property (covers all protocols/subdomains) and add URL prefix if needed for sub-sites.
• Submit XML sitemaps: main, products, categories; auto-update on publish.
• Check Index Coverage weekly; fix canonical conflicts and soft 404s.
• Validate Product structured data; resolve warnings that drop rich results.
• Monitor Core Web Vitals (mobile first). Prioritize LCP images, CLS layout shifts, JS bloat.
• Use URL Inspection when launching new products or large catalog changes.

If a product page doesn’t index, no amount of on-site UX will convert searchers—it simply can’t be found.

1) High Impressions, Low CTR → Improve Packaging

• In GSC: filter a category folder (e.g., /rings/), sort by impressions, find pages with CTR < 1.5%.
• Review query intent; adjust title tags & meta descriptions to match modifiers (size, metal, price band).
• Add structured data (Product, Offer, Review) for rich result eligibility.
• In GA4: confirm affected pages have healthy engagement; if bounce/short engagement, refine above-the-fold content.

2) Traffic Up, Revenue Flat → Funnel Leak

• In GA4: analyze view_item → add_to_cart by device; identify outliers.
• Check variation availability, shipping costs, or trust elements (reviews, returns) on low-performing PDPs.
• In GSC: ensure the queries bringing traffic match transactional intent; if not, expand content and internal links.

3) New Collection Not Ranking → Indexing & Internal Links

• In GSC: inspect the URL, confirm “Indexed, submitted in sitemap.”
• Fix canonical issues; ensure it’s not blocked by parameters or robots rules.
• Add internal links from relevant hubs and the homepage module.
• In GA4: validate visits and engagement post-publish; iterate titles if CTR remains low.

4) Mobile CVR Weak → CWV + UX

• In GSC: Core Web Vitals → mobile issues (LCP, CLS). Optimize hero image, preconnect CDNs, reduce layout shifts.
• In GA4: segment by device; compare add-to-cart and checkout start rates.
• Prioritize speed & clarity over heavy scripts on PDP and cart.

“Fix the Low-CTR Winners” Report

• GSC → Performance → filter by category folder → sort by impressions.
• Flag pages with CTR below category median; map top queries to missing terms in titles.
• Add pricing/USP modifiers and test FAQs on the page; recheck in 14–28 days.

“Find High-Intent Queries Without Pages”

• GSC → Queries with words like “buy,” “price,” “near me,” “best [type].”
• If clicks/impressions are attached to blog content, create or strengthen a corresponding category/PDP.
• In GA4, track performance post-launch; add internal links from related guides.
