MonsterInsights vs ExactMetrics vs Site Kit: WooCommerce Revenue Tracking Tested

Three Plugins, One Question: Does the Purchase Event Fire?#

Every comparison covers features and pricing. This one tests the thing that actually matters for WooCommerce stores: revenue tracking accuracy.

MonsterInsights, ExactMetrics, and Google Site Kit are the three analytics plugins WooCommerce store owners evaluate most often. They all connect your store to Google Analytics 4. They all display traffic data in your WordPress dashboard. They all claim to “support WooCommerce.”

What none of their marketing pages tell you is whether the purchase event actually fires on your specific WooCommerce setup. A purchase event that fires reliably on a default WooCommerce install with the Storefront theme can fail silently on a store running Elementor’s custom thank-you page, WooCommerce’s block-based checkout, or an aggressive page cache. That silent failure means revenue data stops flowing to GA4 — and you won’t notice until you check your reports days or weeks later.

This comparison tests the question every WooCommerce store owner should ask first: which plugin actually tracks revenue correctly on real-world WooCommerce configurations — not just the default demo setup?

MonsterInsights has over 3 million active installs and tracks WooCommerce purchase events, add-to-cart actions, and checkout funnels automatically through its eCommerce addon at $99.50/year — without requiring Google Tag Manager configuration.

MonsterInsights: 3 Million Installs and Automatic WooCommerce Tracking#

The most popular analytics plugin handles WooCommerce ecommerce tracking without GTM — but only on the paid plan.

MonsterInsights crossed 3 million active installs in 2026, making it the most widely used Google Analytics plugin for WordPress (MonsterInsights / SeedProd, 2026). The free Lite version handles basic GA4 setup and pageview tracking. The Pro version at $99.50/year unlocks the eCommerce addon that tracks WooCommerce purchase events, add-to-cart actions, checkout funnels, product performance, and revenue attribution automatically.

The “automatically” part is what justifies the price for non-technical store owners. MonsterInsights injects the tracking code through WordPress hooks rather than requiring a GTM container. You install the plugin, activate the eCommerce addon, and purchase events start flowing to GA4. No tag configuration, no dataLayer debugging, no GTM Preview Mode. For store owners who don’t know what GTM stands for, that’s the difference between having revenue data and not.

MonsterInsights also offers features that GA4’s native interface buries. The User Journey report shows exactly which pages a customer visited before purchasing — a view that requires custom explorations in GA4 but displays in one click inside MonsterInsights. The plugin hosts the gtag.js script locally rather than loading it from Google’s servers, eliminating an external request that penalises Core Web Vitals scores (SeedProd, 2026).

The Charlie Chat AI feature, available on Pro plans, lets you ask questions about your WooCommerce revenue in plain English. “Which traffic source drove the most revenue last month?” gets a direct answer without building a custom GA4 report.

Google Site Kit: Free From Google, Blind to WooCommerce Revenue#

Google’s official WordPress plugin connects four Google services — and none of them track WooCommerce purchases out of the box.

Google Site Kit is free, official, and integrates GA4, Search Console, AdSense, and PageSpeed Insights into your WordPress dashboard. For bloggers and content sites, it’s the obvious choice. For WooCommerce stores, it has a critical gap: Site Kit does not support native WooCommerce ecommerce tracking (HasThemes / FunnelKit, 2026).

That means no purchase events, no add-to-cart tracking, no checkout funnel analysis, no revenue attribution, and no product performance data — unless you configure them separately. The path to WooCommerce tracking through Site Kit requires installing a GTM plugin (GTM4WP or GTM Kit), creating a GTM container, building GA4 ecommerce tags, testing them in GTM Preview Mode, and debugging the dataLayer. Most WooCommerce store owners who install Site Kit for “free analytics” never complete this setup. They see pageviews and traffic sources in their dashboard and assume ecommerce tracking is working. It isn’t.

Google Site Kit does not support native WooCommerce ecommerce tracking — to track purchase events, store owners must install a separate GTM plugin like GTM4WP or GTM Kit and configure tags manually, a process most non-technical store owners never complete.

The irony is that Site Kit’s dashboard looks complete. It shows sessions, users, search queries, and AdSense earnings. The absence of ecommerce data isn’t flagged — there’s no warning that purchase events aren’t configured. A store owner can run Site Kit for months, check their dashboard daily, and never realise their GA4 property has zero revenue data.

ExactMetrics: The Mirror Plugin Most Stores Don’t Know About#

ExactMetrics offers nearly identical WooCommerce tracking at the same price — and adds admin bar insights MonsterInsights doesn’t have.

ExactMetrics is a sister plugin to MonsterInsights with over 1 million users, offering the same GA4 integration, WooCommerce ecommerce tracking, and WordPress dashboard reports at the same $99.50/year price point (IsItWP / ExactMetrics, 2026). The feature overlap is so extensive that most comparison articles struggle to differentiate them.

The genuine difference is the admin bar page insights. ExactMetrics displays real-time traffic stats for whatever page you’re viewing on the frontend — a feature that MonsterInsights doesn’t offer. For store owners who spend time browsing their own site and want instant visibility into how each product page performs, that context-sensitive data is useful.

ExactMetrics also targets agencies managing multiple WordPress sites. The pricing tiers scale from a single site to 100 sites at $699.50/year. For agencies that standardise on one analytics plugin across client sites, ExactMetrics and MonsterInsights offer equivalent functionality with slightly different management interfaces.

The WooCommerce tracking works the same way as MonsterInsights — install the plugin, activate the eCommerce addon, and purchase events flow to GA4 without GTM. Same hooks, same events, same architectural dependency on the woocommerce_thankyou page loading correctly.

The woocommerce_thankyou Hook Problem All Three Share#

Every browser-based analytics plugin depends on one WordPress hook firing on one page. When it doesn’t, revenue data goes dark.

This is the section that matters most and appears in none of the other comparisons. MonsterInsights, ExactMetrics, and any GTM-based tracking configured through Site Kit all depend on the woocommerce_thankyou hook to fire purchase events. That hook triggers when the WooCommerce order confirmation page loads. When it doesn’t load — or loads incorrectly — your purchase event never fires (Seresa / GitHub, 2026).

Three common scenarios break it. First, custom thank-you page templates. If your WooCommerce theme or page builder (Elementor, Divi, Beaver Builder) uses a custom order confirmation template that doesn’t trigger the standard WooCommerce hooks, the purchase event never fires. Your order completes. Payment processes. The customer sees a confirmation. GA4 sees nothing.

Second, page caching. An aggressive cache plugin can serve a stale order confirmation page to the next visitor. The tracking code fires with the previous order’s data, creating either a duplicate transaction or a missed event depending on how the cache invalidation handles query parameters.

Third, WooCommerce’s block-based checkout. The new checkout experience handles the confirmation step differently from the legacy shortcode-based checkout. GTM4WP documented this as GitHub issue #404 — plugins that moved their purchase tracking to the woocommerce_thankyou hook found it failing silently with the block-based checkout on certain themes (Seresa, 2026).

The fix for all three scenarios is the same: server-side tracking that fires from the woocommerce_payment_complete hook on your server, not from a browser loading a page. Server-side events don’t depend on page templates, aren’t affected by caching, and work identically regardless of which checkout experience you run.

Page Speed Impact: Which Plugin Loads Fastest on WooCommerce#

Analytics plugins add JavaScript to every page. On WooCommerce stores already heavy with plugins, the marginal weight matters.

MonsterInsights hosts the GA4 tracking script (gtag.js) locally within WordPress rather than loading it from Google’s external CDN. That eliminates one external request, which Google’s own PageSpeed Insights penalises. For WooCommerce stores where Core Web Vitals directly affect Google search ranking, local hosting is a meaningful optimisation (SeedProd, 2026).

Site Kit loads Google’s scripts from external domains by default. Each Google service connected through Site Kit (GA4, Search Console, AdSense) adds its own external request. On a WooCommerce store already running 4–6 marketing scripts, those additional external requests compound.

ExactMetrics also hosts scripts locally, matching MonsterInsights on page speed impact. For stores where the choice between MonsterInsights and ExactMetrics comes down to marginal differences, page speed isn’t the tiebreaker — they perform comparably.

The broader context: 31.5% of users run ad blockers that prevent any analytics plugin from firing events at all (industry data, 2026). On those visits, MonsterInsights, ExactMetrics, and Site Kit all fail equally. Server-side tracking captures what every browser-based plugin misses.

Feature and Pricing Comparison#

Hook Dependency	woocommerce_thankyou	woocommerce_thankyou	GTM plugin’s hook choice

The bottom row is the one that determines reliability. All three depend on browser-side JavaScript and WooCommerce hooks firing correctly. When they don’t, the features above become irrelevant — you’re tracking zero revenue regardless of which plugin you chose.

Which One for Your WooCommerce Store#

The answer depends on your technical ability and what you’re willing to pay for convenience.

Choose MonsterInsights Pro if: you want WooCommerce revenue tracking that works without GTM, you value user journey reports and AI-powered analytics questions, and you’re willing to pay $99.50/year for setup simplicity. Best for store owners who want data without touching code.

Choose ExactMetrics Pro if: you want the same WooCommerce tracking at the same price with admin bar page insights. Best for agencies managing multiple sites or store owners who want real-time stats while browsing their own store.

Choose Google Site Kit if: you’re comfortable configuring GTM for WooCommerce ecommerce tracking, you want Search Console and AdSense data alongside GA4 in one dashboard, and you don’t want to pay for an analytics plugin. Do not choose Site Kit if you expect WooCommerce purchase tracking to work out of the box. It won’t.

For all three: test that your purchase event actually fires by completing a test order and checking GA4’s Realtime report within 30 seconds. If the purchase event doesn’t appear, the plugin isn’t tracking your revenue — regardless of what the WordPress dashboard shows.

Key Takeaways#

• MonsterInsights is the simplest path to WooCommerce revenue tracking: 3M+ installs, automatic ecommerce tracking at $99.50/year, local script hosting for page speed, and AI-powered analytics via Charlie Chat. No GTM required.
• Google Site Kit is blind to WooCommerce revenue: Free and official, but no native ecommerce tracking. Purchase events require a separate GTM plugin and manual tag configuration that most store owners never complete.
• ExactMetrics mirrors MonsterInsights at the same price: 1M+ users, identical WooCommerce tracking, same hooks. The differentiator is admin bar page insights and agency-scale multi-site management.
• All three share the same structural weakness: Browser-side JavaScript dependent on the woocommerce_thankyou hook. Custom themes, page caching, and block-based checkout can all break purchase tracking silently.
• Test before you trust: Complete a test purchase and verify the event appears in GA4 Realtime. If it doesn’t show within 30 seconds, your revenue tracking is broken regardless of which plugin you installed.
• Server-side tracking is the architectural fix: Events fired from woocommerce_payment_complete on your server aren’t affected by themes, caching, or checkout templates. They work when every browser-based plugin fails.
