# Best Tag Management Systems - Page 2

*By [Alanna Iwuh](https://research.g2.com/insights/author/alanna-iwuh)*


A tag is a short piece of Javascript code that is embedded on web pages, mobile applications, and other relevant digital channels to collect first-party user data. Tag management systems simplify and unify the management and maintenance of tags across all digital properties. This is important because the collected data from those tags equips companies with insight to drive better customer experience. With tag management systems, marketers can consolidate and standardize the process of updating tags (streamlining any digital marketing campaigns) and reduce dependence on their IT or development teams. Furthermore, tag management software encourages agility. These solutions provide containers through which marketers can easily add, edit, or remove tags at will. Tag management systems can vary in functionality, with the most advanced versions offering customization and data management.

To qualify for inclusion in the Tag Management category, a product must:

- Collect, and then centralize, user data
- Offer a simple interface for users both familiar and unfamiliar with code
- Provide a library or catalog of tags
- Deliver tag-testing capabilities or integrate with [A/B testing solutions](https://www.g2.com/categories/a-b-testing)
- Track and monitor user engagement and other user behaviors

### 2. [Crownpeak TagControl](https://www.g2.com/products/crownpeak-tagcontrol/reviews)
The more marketing technology you add to your website, the more parties have access to your user data. We're not just talking about the vendors you have direct relationships with, we're talking about their partners who through association also gain access. With TagControl, you get visibility and control over every vendor that's tracking the visitors on your website, so you can clean house and improve your marketing ops, tighten security, and focus on the user experience. Go Beyond Tag Management: Where traditional tag managers fall short is in their inability to prevent or stop tags from introducing new third-party vendors onto your websites (piggybacking). While common, this act reduces the transparency and control that you have into your marketing stack and increases the risk of security, performance, and data privacy concerns. TagControl functions at the individual tag level and lets you control access regardless of how the vendor was introduced. TagControl helps quickly solve where your vendors: - Cause page latency issues - increasing your bounce-rate because visitors won't wait for your content to load. - Trigger security alerts that create user doubt and site abandonment. - Negatively impact your search engine rankings because of suspicious code or spam concerns. - Increase the likelihood of data leakage through unauthorized access. - Elevate security risks. - Undermine your compliance with laws like the GDPR, ePrivacy Directive and PIPEDA.

### 4. [Reaktion](https://www.g2.com/products/reaktion/reviews)
Reaktion.com is a profit-first tracking and analytics platform built for ecommerce brands and agencies that have outgrown ROAS. Most ad platforms optimize for the data they can see. The problem is that revenue is not profit, and pixels often miss the full picture. Product costs, shipping, VAT, payment fees, discounts, refunds, repeat purchases, and new customer revenue all change whether a campaign is actually making money. Reaktion brings that commercial reality into the places where ecommerce teams already optimize, report, and make budget decisions. With Reaktion, teams can connect ecommerce, marketing, automation, organic, and affiliate data in one near real-time platform. Reaktion uses server-side tracking and first-party order data to give brands a clearer view of performance across Google Ads, Meta, TikTok, GA4, Klaviyo, Shopify, WooCommerce, Magento, BigCommerce, PrestaShop, and more. Instead of only looking at ROAS, teams can track the metrics that decide whether growth is healthy: profit, POAS, MER, new customer revenue, true CAC, refunds, on-sale revenue, product margin, customer lifetime value, attribution, and SKU-level performance. Reaktion also helps send stronger signals back to marketing platforms, so algorithms can optimize using the data that actually matters. For ecommerce teams, Reaktion acts as a profit command center. See which campaigns, channels, creatives, products, and markets are driving profitable growth. Spot where impressive revenue is quietly turning into weak margin. Understand how returns, discounts, acquisition costs, and product economics affect performance before budget is wasted. For agencies, Reaktion makes client reporting sharper and less spreadsheet-dependent. Agencies can manage multiple stores and clients from one overview, build custom reports, show profit-based performance, and give clients a clearer answer to the question that matters most: did this marketing actually make money? Key capabilities include server-side tracking, real-time dashboards, custom report building, marketing attribution, customer lifetime value analysis, profit optimization, KPI and target tracking, multi-store overview, Creative Cockpit, product analytics, mobile app access, and agency reporting. Reaktion is designed for teams that want to scale with financial clarity, not vanity metrics. Because ROAS can look great while profit leaves through the back door.

### 13. [Calendly Event Tracker](https://www.g2.com/products/calendly-event-tracker/reviews)
Stop Losing Calendly Conversion Data If you've embedded Calendly on your website, standard GTM click tracking doesn't work on it. Calendly loads inside an iframe, which blocks all normal DOM-based event tracking. Most workarounds ask you to write custom HTML listener scripts, build triggers from scratch, or pay for a higher Calendly tier just to unlock their native GA4 integration — which only connects to a single GA4 property anyway. The Calendly Event Tracker for GTM eliminates all of that. Import one .json container file into your Google Tag Manager workspace, add your GA4 Measurement ID, and publish. You're done in under 10 minutes — with complete, deduplicated Calendly tracking running in production.
