• Find a great Google Tag Manager alternative in Matomo Tag Manager

  29 avril 2020, par Joselyn Khor — Analytics Tips, Development, Marketing, Plugins
  If you’re looking for a tag management system that rivals Google’s, then Matomo Tag Manager is a great Google Tag Manager alternative that takes your tracking to the next level.

  What’s a tag manager ?

  If you’re not familiar with Google Tag Manager or Matomo Tag Manager – they’re both free tag management systems that let you manage all your website code snippets (tags) in one place. 

  Tags are typically JavaScript code or HTML that lets you integrate various features into your site in just a few clicks. For example : analytics codes, conversion tracking codes, exit popups and surveys, remarketing codes, social widgets, affiliates, and ads. With a tag manager, you get to easily look into and manage these different tracking codes.

  Why use a tag manager ?

  Tag management systems are game changers because they let you track important data more effectively by easily adding code snippets (tags) to your website. 

  By not needing to hard code each individual code you also save time. Rather than waiting for someone to make tag changes and to deploy your website, you can make the changes yourself without needing the technical expertise of a developer.

  Why is Matomo Tag Manager a great Google Tag Manager alternative ?

   Matomo Tag Manager is a great Google Tag Manager alternative. Not only does it let you manage all your tracking and marketing tags in one place, it also offers less complexity and more flexibility. 

  By tagging your website and using Matomo Tag Manager alongside Matomo Analytics, you can collect much more data than you’d be able to otherwise. 

  A bonus to using Matomo is the privacy and data ownership aspect. With Matomo you also get the added peace of mind that comes with 100% data ownership and privacy protection. You will never be left wondering what’s happening to your data. Rest assured knowing you’re doing the best to protect user privacy, while getting useful insights to improve your website. 

  And since Matomo Tag Manager is the one of the best alternatives to Google Tag Manager, you’ll gain more than you lose by having full confidence that your data is yours to own.

  

  Three key benefits of using Matomo Tag Manager :

  • Empowers you to deploy and manage your own tags
    This takes the hassle out of needing a web developer to hard code and edit every tag on your website. Now you can deploy tracking code on chosen pages and track various data yourself. 

  • Open up endless possibilities on data tracking
    Dig a lot deeper to track analytics, conversions, and more. Now you can implement advanced tracking solutions without needing to pay an external source. 

  • Save time and create your own impact
    With limited resources you certainly don’t want to be wasting any time having to go back and forth with an external party over what tags to add or take away. An over-dependence on web developers or agencies carrying out tag management for you, stalls growth and experimentation opportunities. With a tag management system you have the convenience of inserting your own tags and getting to a desired outcome faster. You won’t have to forgo tracking opportunities because now it’s in your hands.

• Why do you need analytics for your WordPress ?

  7 avril 2020, par Joselyn Khor — Analytics Tips, Plugins
  Not many people know this, but having a WordPress analytics tool gives you a competitive advantage. It’s also essential to the growth of your website. For many businesses, websites are the main driver of revenue and sales. In the case of blogs, it’s your first chance to make a lasting impression.

  Now, maybe you’ve heard of Google Analytics or even the privacy-friendly alternative, Matomo Analytics, but have never tried them ? These are analytics platforms that help you understand your website traffic and visitors. (You can find these platforms as plugins in the WordPress directory !)

  They’re important because the insights you get help you determine what changes to make to improve your website. Without them you could face a tougher time figuring out what’s working, what the issues are (and solving them before they get out of hand), and making sure you’re taking your website in the right direction. 

  WordPress analytics gives you an understanding of what’s actually going on.

  How does a WordPress analytics plugin benefit your website ?

  What this means for you is getting a toolkit to learn how to get more sales or followers and subscribers (aka conversions in analytics terms). 

  By getting insights into user behaviour, content performance, and how you can optimise your website, you can reach more of your goals, like increasing sales or growing your audience.

  A WordPress analytics tool helps you get more traffic to your site

  You get a range of features which tell you which acquisition channels are working for you like – social media, search engines, and other websites mentioning you. This helps you make an informed decision on where to focus energies (or spend) to get more of the ideal people coming through to your website. 

  

  Example : Looking through your acquisition channels and seeing that Reddit drives a lot of traffic through to your website. Since this channel seems to be working for you, you could then spend more time on Reddit posts to increase traffic.

  But getting more traffic isn’t all there is to it. Once they land on your site, you want them to stay for a little longer so they are intrigued by what you’re offering. Be it a product, or awesome content.

  Which leads us to …

  Increasing engagement by learning about visitor behaviour

  When you get a solid number of visitors on your website, it’s good to then learn about how they behave on your site. A WordPress analytics tool helps with engagement since you’re seeing what’s appealing to them, and what isn’t.

   Increasing engagement is good for a few reasons. 

  • You end up speaking the language of your readers. 
  • You can make a difference with the information you’re putting out. 
  • You get loyal customers and believers in your organisation. 

  With more engaged visitors, you can build trust with them and eventually be able to convince them that your product, service, or blog is needed in their lives.

  

  Example : Looking through entry and exit pages to see what first impression is making them stay, and what impression is making them leave. This helps you redirect efforts to give your website a better chance of getting visitors to stay longer.

  Improving your content and engagement can lead to more conversions

  After you get visitors engaged, it’s time to convert. 

  Whether you have an ecommerce site or freelance blog, you’ll need to know how to boost conversions. This simply means getting people to achieve more of the actions you’re wanting them to take on your site. Like subscribing to your newsletter or adding items to a cart.

  With conversion optimization features, you’re finding out how well your website is designed to get buyers through a journey to conversion. 

  

  Example : Say you’ve created a newsletter sign up page, but you’re not getting as many sign ups as you’d like. With a web analytics tool, you can look into it further. A funnels feature could tell you how they’re getting to that page. If people can’t find your page, that could be reason for low conversion rates. Or, maybe you are getting people landing on this page, but you can’t tell why they’re not signing up. Try setting up a heatmap to see how far they’re scrolling down your page to the sign up section. Through these conversion optimization features, you can make tweaks that significantly improve conversions.

  So, how does the Matomo Analytics for WordPress plugin help with all of this ?

  

  Matomo Analytics for WordPress is a free web analytics plugin that gives you access to all the features mentioned above, right in your own WordPress dashboard. It’s completely free to use and is handy for users of all skill levels. From beginners right through to advanced analysts. 

  You get to move through all the stages to increase traffic, increase engagement, and convert. By using Matomo for WordPress, you put yourself in a better position to track all the needed data from your WordPress website. 

  You have this toolkit to improve your website for free, with a few clicks ! 

  By getting useful insights like visitors, acquisitions, bounce rates etc. you gain a new perspective on how to improve your website so it’s better at doing what you created it to do. Getting these insights also means giving yourself the confidence to do what’s best for your website in a data-driven way. 

  With all this knowledge, you can be competitive, or grow enough that you’re leaving your competitors in the dust.
