• Can't install the modules

  13 janvier 2019, par Megaluk

  I’m trying to install ffmpeg-binaries it works perfectly local but when I go to hiroku it starts to say that he can’t find the modules.

  This is for a Discord bot, running node.js I tried to install with npm other ffmpeg’s but only that works without implementing the ffmpeg itself

  Installing node modules (package.json + package-lock)

• 16 Website Metrics to Track If You Want to Grow Your Business

  9 avril 2024, par Erin

  Conversion rate.

  Bounce rate.

  Sessions.

  There are dozens of metrics to keep up with in web analytics. It can be confusing at times trying to keep up with everything.

  But, if you want to improve your website performance and grow your business, you need to know what they are and how they work.

  Why ?

  Because what you measure gets managed. This is true in your personal life and business. You must track various website metrics to help your business reach new heights.

  In this guide, you’ll learn about the most important website metrics, why they’re important and how to track them to grow your brand.

  What are website metrics ?

  Your website is your digital headquarters.

  It’s not a static place. Instead, it’s a vibrant, interactive hub your visitors and customers can engage with daily.

  Every time a user interacts with your website, you can track what’s happening.

  Website metrics help you measure how much your visitors and customers interact with your website. 

  These engagement metrics help you understand what your visitors are doing, where they’re coming from, how they’re moving on your website and how long they stay. They can even give you insights into what their goals are.

  

  If you aren’t tracking your website metrics, you won’t know how effective your website is.

  By paying close attention to your key metrics within a web analytics platform like Matomo, you’ll be able to see how well your marketing is doing and how your visitors are engaging so you can improve the user experience and increase conversions.

  16 website metrics to track

  Here are the top 16 website metrics you need to be tracking if you want to grow your business :

  1. Pageviews

  A pageview is the number of times a web page has been viewed. 

  Many pageviews can indicate a successful search engine optimisation (SEO) or marketing campaign — it can be used to show positive results for these initiatives.

  It can also help you determine various issues on individual pages. For instance, performance issues or poor website structure can cause visitors to get lost or confused while navigating your website.

  

  2. Average time on page

  Average time on a page is simply the time visitors spend on a specific page (not the entire website) ; tracking users’ time on various pages throughout your website can give you insights that can help you improve certain pages.

  If you get tons of traffic to a particular page, but the average time a visitor stays on that page is minimal, the content may need some work.

  Tracking this data can help determine if your website is engaging for your visitors or if you need to modify certain aspects to increase your visitors’ stay. Increasing the average time on the page will help boost your conversions and search engine rankings.

  3. Actions per visit

  Actions per visit is a key metric that tracks the average number of actions a visitor takes every time they visit your website. This data can help you track your audience engagement and the effectiveness of your content across your entire website.

  An action is any activity performed by your visitors on your website like :

  • Outlinks
  • Downloads
  • Page views
  • Internal site searches

  The higher your actions per visit, the more engaging your audience finds your website content. A side effect of increased actions is staying longer on the site and more likely to convert to your email list as a subscriber or pay for products as a customer.

  4. Bounce rate

  Like a bouncy ball, your website’s bounce rate measures how many users entered your site and “bounced” out without clicking on another page. This metric can be extremely helpful in determining user interest in your content. 

  You might be getting many visitors to your website, but if they “bounce” after visiting the first page they land on, that’s a great indicator that your content is not resonating with your audience.

  Remember, this metric should be taken with a grain of salt. 

  Your bounce rate may indicate that visitors are finding the exact information that they wanted and leaving pleased, so it’s not a black-and-white metric.

  For example, if you have a landing page with a high bounce rate, then that’s likely not a sign of a good user experience. But, if you have a knowledge base article and they just need to find some quick information, then it could be a good indicator.

  5. Conversions

  The first step in tracking conversions is defining what a conversion is for your website. 

  Do you want your audience to :

  • View a blog post
  • Purchase a product
  • Download an eBook
  • Sign up for a consultation call

  Determine what that conversion is and track how often users take that action on your website.

  This helps you understand if your marketing and content strategies are working toward your pre-defined conversion goal.

  

  6. Conversion rate

  A conversion rate is the percentage of visits that triggered a conversion. Knowing this metric lets you plan, budget, and forecast future growth.

  For example, 5% of your website visitors take action and convert to customers. With this information, you can make better informed financial decisions regarding your marketing efforts on your website to help increase traffic and future conversions.

  While there are basic conversion rate benchmarks to strive toward, it ultimately depends on your goals and the specific conversions you decide to track that are best for your business. 

  That being said, Matomo has some best practices to help you optimise your conversion rates, no matter what conversion metric you are tracking.

  7. Exit rate

  While “bounce rate” and “exit rate” are similar, “exit rate” is the percentage of visits to a website that ended on a particular page.

  Knowing which pages have the highest percentage of visitors exiting your website gives you key information on the pages that may need to be improved.

  If you see that your “exit rate” is highest on pages before the checkout (or other CTA’s you have established), you will want to dive into what’s causing visitors to leave from that page. For example, maybe it’s the content, the copy or even a broken link.

  This is a great metric to help determine where you have breakdowns between you and your visitors. Improving your exit rate can help guide visitors through your website funnel more easily and boost your conversion rates. 

  

  8. Top pages

  The top pages on your website are the pages that receive the most visits. Understanding what your top pages are can be crucial in planning and guiding your marketing strategies moving forward.

  Your top pages can help you determine the most engaging content for your audience. This can be extremely helpful in guiding your visitors to certain pages that other users find more valuable.

  It also helps you determine if you need to focus more attention on different parts of your website to increase user engagement in those areas.

  For example, maybe your most-viewed pages have less copy and more photos or videos. Understanding this lets you know that incorporating more media into other pages will boost future engagement.

  9. Traffic sources

  Your traffic sources are the channels that are driving visitors to your website. The four most common traffic sources are :

  • Direct Entry : Typing your website URL into their browser or visiting via a bookmark they saved
  • Websites/Referral : Clicking on a link to your site from another website
  • Search Engines : Using search engines (Google, Bing or Yahoo) to find your website
  • Campaigns : Visitors directed to your website through specific marketing campaigns, such as email newsletters, Google Ads, promotional links, etc.
  • Social Networks : Visitors accessing your website by clicking on links shared on social media platforms like Facebook, X (Twitter), LinkedIn, etc.

  Understanding where your visitors are coming from can help you focus your marketing efforts on the traffic sources with the highest conversion rates. 

  Suppose your email marketing campaign isn’t driving any traffic to your website, but your ad campaign is responsible for over 25% of your conversions. In that case, you might consider doubling your advertising efforts.

  10. Form average time spent

  Forms are a crucial part of your website’s marketing strategy. Forms can help you :

  • Learn more about your visitors
  • Gather feedback from your audience
  • Convert visitors into email subscribers
  • And more

  Form average time spent is the average amount of time a visitor spends on a specific form on your website. The time is calculated as the difference between the first interaction with a form field (for example, a field focus) and the last interaction with a form.

  Want to convert more visitors into leads ? Then, you need to understand your form analytics better. Learn more here.

  11. Play rate

  If you want to keep your audience engaged (and convert more visitors), you need to publish different types of media.

  But if your video or audio content isn’t performing well, then you’re wasting your time.

  That’s where play rate comes in. It’s calculated by analysing visitors who watched or listened to a specific media after they have visited a web page.

  With play rate, you can track any video, podcast, or audiobook plays.

  You can easily track it within Matomo’s Media Analytics. The best part ? This feature works out of the box, so you don’t need to configure it to start leveraging the analytics.

  12. Returning visitors

  Returning visitors are users who visit your website more than once over a specific time.

  You will want to measure the number of returning visitors to your website, as this information can give you additional insights into your marketing strategies, company branding and content.

  It can also help you better understand your customer base, giving you a clearer sense of their top desires and pain points.

  13. Device type

  Device type tracks the different devices visitors use to visit your website. These could be :

  • Tablets
  • Mobile phones
  • Desktop computers

  Knowing what your visitors are using to access your website can help you improve the overall user experience.

  For example, if 80% of your visitors use mobile phones, you could think about optimising your web pages to format with mobile devices. 

  

  14. Top exit pages

  Top exit pages are the pages that a visitor leaves your website from the most.

  Each web page will have a specific exit rate percentage based on how many people leave the website on a particular page.

  This can be quite helpful in understanding how visitors interact with your website. It can also help you uncover and fix any issues with your website you may not be aware of.

  For instance, one of your product pages has the highest exit rate on your website. By looking into why that is, you discover that your “Add to Cart” button isn’t functioning correctly, and your visitors can’t buy that particular product, so they exit out of frustration.

  15. Marketing attribution

  Marketing attribution (multi-touch attribution) helps you see which touchpoints have the greatest impact on conversions.

  Within Matomo, revenue attribution involves assigning credit for revenue across multiple touchpoints that contribute to a conversion.

  Matomo’s multi-touch attribution models use different weighting factors, like linear or time decay, to allocate credit to each touchpoint based on its influence.

  Matomo’s multi-touch attribution reports provide insights into how revenue is distributed across different touchpoints, marketing channels, campaigns, and actions. These reports allow you to analyse the contribution of each touchpoint to revenue generation and identify the most influential interactions in the customer journey.

  16. Event tracking

  Every website has multiple actions a user can perform called “events”. These could be downloading a template, submitting contact information, signing up for a newsletter or clicking a link.

  Tracking events can give you additional context into what your visitors are interested in or don’t care about. This allows you to target them better through those events, potentially creating new, unique conversions and boosting the growth of your business.

  It can also lead to discovering potential issues within your website if you notice visitors aren’t taking action on certain CTAs, such as broken links or lack of content on certain pages. By uncovering these issues, you can quickly fix them to increase your conversions.

  Every interaction a visitor has on your site is unique and leaves valuable clues you can use to improve all aspects of your site experience.
