Easy testing: Our unique Debug Console and Preview Mode make it easy to verify that new tags are working properly, before you publish any changes. So marketers can check tags themselves, and webmasters can breathe easy.

Empowers Agencies:  Multi-account support and user permissions mean agencies can easily use Google Tag Manager to help manage their clients’ tags.

Rule driven: You want specific tags to work at specific times, like when a user reaches a thank-you page after a purchase. That’s why Google Tag Manager lets you create custom rules and macros to collect exactly the right information at the right time.

Plays well with others:  Google Tag Manager supports Google and non-Google measurement and marketing tags, many with built-in templates. So you can quickly adopt new marketing tools whenever you’re ready.

Spur is a fun and easy way to critique web designs in ways you’ve never done before. Just paste a URL (or upload an image) and you’ll be able to use seven different tools to help you find what’s working (and what isn’t!).

Share what you’ve learned, of course! Spur generates a unique URL you can use to share your design with any of the tools applied to it. Get feedback from your team by uploading the altered image to Notable; they’ll be more than happy to dig their Spurs into your design.
