In the high-speed world of digital marketing today, it’s all about the data. Without tracking and insights, businesses have no idea how to decide on their marketing campaigns or SEO work. That’s where Google Tag Manager (GTM) comes into play.
Many marketers hear of GTM, but they’re not sure what the heck it does, how it functions, or why that even matters. GTM might be the solution you’ve been searching for if you’ve been having to see developers every time you need a tracking code added.
I’d want to explain what Google Tag Manager is, why it’s so effective, and how it may complement your SEO approach in this article.
What is Google Tag Manager (GTM) anyway?
You may manage and use marketing tags, small bits of code or tracking pixels, on your website (or mobile app) without changing the code by using Google Tag Manager (GTM), a free service from Google.
All of your tracking scripts are centralized in GTM, which you might think of as a safe box. Rather than clogging your site with dozens \(or more\) tags, GTM allows you to easily integrate, update, and manage them all with a user-friendly interface.
With GTM, you can set up:
- Google Analytics tracking
- Facebook Pixel
- LinkedIn Insight Tag
- Remarketing campaigns
- Conversion tracking
- It enables you to track events (such as clicks, downloads, forms, and video plays).
And the best part? You don’t always have to ask your developers to do this.
Why Use GTM?
And here are a million different reasons for businesses, marketers, SEOs, etc. to love Tag Manager:
- Tag faster: Add new tags or update existing ones in minutes.
- More flexibility: Developer help is not required for all tracking changes.
- Increased data accuracy: Control all tags from one single container.
- Free: GTM is free from Google.
- Scalable: Great for small businesses and enterprises.
How Does GTM Work?
Three primary components make Google Tag Manager go:
- Tags: Code that sends information (such as to Google Analytics).
- Triggers: The conditions that let GTM know when a tag should fire, like when someone clicks a button.
- Variables: Other data that GTM uses to modify triggers or tags (e.g., button text).
Instead of injecting specific tags into your site’s code, you inject a single GTM container snippet. Afterwards, everything is managed via the GTM interface.
GTM and SEO: The Connection
Although GTM is mostly known for paid advertising and conversion tracking, it can be highly beneficial for SEO tactics. Here’s why:
- Track user interactions: Observe how users interact with your site with GA4 event tracking.
- Track Core Web Vitals with GTM: How to measure and GTMize for Google’s ranking signals.
- Form tracking: know where users abandon lead gen forms.
- Content experiments: Test one piece of content for an A/B test to see which one will perform better.
- Better audience understanding: Learn how organic visitors behave differently from paid visitors.
Using GTM is the one way to gather and organize good-quality data, which ultimately allows you to make better SEO decisions and take your strategy to the next level.
Benefits of Using GTM for SEO Strategy
- See more: learn how people are interacting with content.
- One-up optimization: Your site is faster with actionable data.
- Less dependence on developers: Marketers can react quickly.
- Seamless integration: Compatible with GA4, Ads, and third-party platforms.
- Full-service digital marketing: SEO and paid ads data can cohabitate in one system.
