You'd be surprised many miss this. If you are starting growth marketer -- get into this flow of deploying & crossing these boxes!
Part of Growth Marketing is a logistics game. How efficiently can you generate growth by executing customers, data, and campaigns across channels? The goal is to become a Full-Stack marketing. Stacks on stacks.
1.) Google Tag Manager (aka GTM)
Look this up. A great challenge for many marketers is that they often have to bother developers to drop in javascript codes to websites for various tools, tracking etc. This creates a logistics nightmare and leaves you at the mercy of the devs to response. With GTM, this allows you to drop one piece of code on a site, and then add/edit/manage other scripts from the GTM dashboard.
2.) Google Analytics
Learn how to drop the code into the site. This will start tracking all traffic. This is a must! Track traffic & results!
3.) Ad Pixels for retargeting ads
Core: Facebook, Google
Optional: Twitter, LinkedIN, Pinterest
Always drop pixels on your site so you can cookie every user that comes through your website. You CANNOT retro active pixel people. So always drop these ASAP. This will allow you to grow your retarget pool.
