• cannot convert FLV to MP4 despite compiling ffmpeg with all codecs

  1er novembre 2013, par Rubytastic

  Try to convert FLV to MP4 with below params, but it always fails. I included also list of codeces that are compiled in. Why It will not convert the FLV to MP4, who knows ?

   ffmpeg -y -i stream2.flv -acodec libmp3lame -ar 44100 -ac 1 -vcodec libx264 stream2.mp4;

• How to Use Analytics & Reports for Marketing, Sales & More

  28 septembre 2023, par Erin — Analytics Tips

  By now, most professionals know they should be using analytics and reports to make better business decisions. Blogs and thought leaders talk about it all the time. But most sources don’t tell you how to use analytics and reports. So marketers, salespeople and others either skim whatever reports they come across or give up on making data-driven decisions entirely. 

  But it doesn’t have to be this way.

  In this article, we’ll cover what analytics and reports are, how they differ and give you examples of each. Then, we’ll explain how clean data comes into play and how marketing, sales, and user experience teams can use reports and analytics to uncover actionable insights.

  What’s the difference between analytics & reports ? 

  Many people speak of reports and analytics as if the terms are interchangeable, but they have two distinct meanings.

  A report is a collection of data presented in one place. By tracking key metrics and providing numbers, reports tell you what is happening in your business. Analytics is the study of data and the process of generating insights from data. Both rely on data and are essential for understanding and improving your business results.

  

  A science experiment is a helpful analogy for how reporting and analytics work together. To conduct an experiment, scientists collect data and results and compile a report of what happened. But the process doesn’t stop there. After generating a data report, scientists analyse the data and try to understand the why behind the results.

  In a business context, you collect and organise data in reports. With analytics, you then use those reports and their data to draw conclusions about what works and what doesn’t.

  Reports examples 

  Reports are a valuable tool for just about any part of your business, from sales to finance to human resources. For example, your finance team might collect data about spending and use it to create a report. It might show how much you spend on employee compensation, real estate, raw materials and shipping.

  On the other hand, your marketing team might benefit from a report on lead sources. This would mean collecting data on where your sales leads come from (social media, email, organic search, etc.). You could collect and present lead source data over time for a more in-depth report. This shows which sources are becoming more effective over time. With advanced tools, you can create detailed, custom reports that include multiple factors, such as time, geographical location and device type.

  

  Analytics examples 

  Because analytics requires looking at and drawing insights from data and reports to collect and present data, analytics often begins by studying reports. 

  In our example of a report on lead sources, an analytics professional might study the report and notice that webinars are an important source of leads. To better understand this, they might look closely at the number of leads acquired compared to how often webinars occur. If they notice that the number of webinar leads has been growing, they might conclude that the business should invest in more webinars to generate more leads. This is just one kind of insight analytics can provide.

  For another example, your human resources team might study a report on employee retention. After analysing the data, they could discover valuable insights, such as which teams have the highest turnover rate. Further analysis might help them uncover why certain teams fail to keep employees and what they can do to solve the problem.

  The importance of clean data 

  Both analytics and reporting rely on data, so it’s essential your data is clean. Clean data means you’ve audited your data, removed inaccuracies and duplicate entries, and corrected mislabelled data or errors. Basically, you want to ensure that each piece of information you’re using for reports and analytics is accurate and organised correctly.

  If your data isn’t clean and accurate, neither will your reports be. And making business decisions based on bad data can come at a considerable cost. Inaccurate data might lead you to invest in a channel that appears more valuable than it actually is. Or it could cause you to overlook opportunities for growth. Moreover, poor data maintenance and the poor insight it provides will lead your team to have less trust in your reports and analytics team.

  The simplest way to maintain clean data is to be meticulous when inputting or transferring data. This can be as simple as ensuring that your sales team fills in every field of an account record. When you need to import or transfer data from other sources, you need to perform quality assurance (QA) checks to make sure data is appropriately labelled and organised. 

  Another way to maintain clean data is by avoiding cookies. Most web visitors reject cookie consent banners. When this happens, analysts and marketers don’t get data on these visitors and only see the percentage of users who accept tracking. This means they decide on a smaller sample size, leading to poor or inaccurate data. These banners also create a poor user experience and annoy web visitors.

  Matomo can be configured to run cookieless — which, in most countries, means you don’t need to have an annoying cookie consent screen on your site. This way, you can get more accurate data and create a better user experience.

  Marketing analytics and reports 

  Analytics and reporting help you measure and improve the effectiveness of your marketing efforts. They help you learn what’s working and what you should invest more time and money into. And bolstering the effectiveness of your marketing will create more opportunities for sales.

  

  One common area where marketing teams use analytics and reports is to understand and improve their keyword rankings and search engine optimization. They use web analytics platforms like Matomo to report on how their website performs for specific keywords. Insights from these reports are then used to inform changes to the website and the development of new content.

  As we mentioned above, marketing teams often use reports on lead sources to understand how their prospects and customers are learning about the brand. They might analyse their lead sources to better understand their audience. 

  For example, if your company finds that you receive a lot of leads from LinkedIn, you might decide to study the content you post there and how it differs from other platforms. You could apply a similar content approach to other channels to see if it increases lead generation. You can then study reporting on how lead source data changes after you change content strategies. This is one example of how analysing a report can lead to marketing experimentation. 

  Email and paid advertising are also marketing channels that can be optimised with reports and analysis. By studying the data around what emails and ads your audience clicks on, you can draw insights into what topics and messaging resonate with your customers.

  

  Marketing teams often use A/B testing to learn about audience preferences. In an A/B test, you can test two landing page versions, such as two different types of call-to-action (CTA) buttons. Matomo will generate a report showing how many people clicked each version. From those results, you may draw an insight into the design your audience prefers.

  Sales analytics and reports 

  Sales analytics and reports are used to help teams close more deals and sell more efficiently. They also help businesses understand their revenue, set goals, and optimise sales processes. And understanding your sales and revenue allows you to plan for the future.

  One of the keys to building a successful sales strategy and team is understanding your sales cycle. That’s why it’s so important for companies to analyse their lead and sales data. For business-to-business (B2B) companies in particular, the sales cycle can be a long process. But you can use reporting and analytics to learn about the stages of the buying cycle, including how long they take and how many leads proceed to the next step.

  Analysing lead and customer data also allows you to gain insights into who your customers are. With detailed account records, you can track where your customers are, what industries they come from, what their role is and how much they spend. While you can use reports to gather customer data, you also have to use analysis and qualitative information in order to build buyer personas. 

  

  Many sales teams use past individual and business performance to understand revenue trends. For instance, you might study historical data reports to learn how seasonality affects your revenue. If you dive deeper, you might find that seasonal trends may depend on the country where your customers live. 

  

  Conversely, it’s also important to analyse what internal variables are affecting revenue. You can use revenue reports to identify your top-performing sales associates. You can then try to expand and replicate that success. While sales is a field often driven by personal relationships and conversations, many types of reports allow you to learn about and improve the process.

  Website and user behaviour analytics and reports 

  More and more, businesses view their websites as an experience and user behaviour as an important part of their business. And just like sales and marketing, reporting and analytics help you better understand and optimise your web experience. 

  Many web and user behaviour metrics, like traffic source, have important implications for marketing. For example, page traffic and user flows can provide valuable insights into what your customers are interested in. This can then drive future content development and marketing campaigns.

  

  You can also learn about how your users navigate and use your website. A robust web analytics tool, like Matomo, can supply user session recordings and visitor tracking. For example, you could study which pages a particular user visits. But Matomo also has a feature called Transitions that provides visual reports showing where a particular page’s traffic comes from and where visitors tend to go afterward. 

  

  As you consider why people might be leaving your website, site performance is another important area for reporting. Most users are accustomed to near-instantaneous web experiences, so it’s worth monitoring your page load time and looking out for backend delays. In today’s world, your website experience is part of what you’re selling to customers. Don’t miss out on opportunities to impress and delight them.

  Dive into your data

  Reporting and analytics can seem like mysterious buzzwords we’re all supposed to understand already. But, like anything else, they require definitions and meaningful examples. When you dig into the topic, though, the applications for reporting and analytics are endless.

  Use these examples to identify how you can use analytics and reports in your role and department to achieve better results, whether that means higher quality leads, bigger deal size or a better user experience.

• Multilingual SEO : A Marketer’s Guide to Measuring and Optimising Multilingual Websites

  26 juin, par Joe

  The web—and search engines in particular—make it easier than ever for businesses of any size to reach an international audience. 

   
  A multilingual website makes sense, especially when the majority of websites are in English. After all, you want to stand out to customers by speaking their local language. But it’s no good having a multilingual site if people can’t find it. 

  That’s where multilingual SEO comes in. 

  In this article, we’ll show you how to build a multilingual website that ranks in Google and other local search engines. You’ll learn why multilingual SEO is about more than translating your content and specific tasks you need to tick off to make your multilingual site as visible as possible. 

  ¡Vamos !

  What is multilingual SEO ? 

  Multilingual SEO is the process of optimising your website to improve search visibility in more than one language. It involves creating high-quality translations (including SEO metadata), targeting language-specific keywords and building links in the target language. 

  

  The goal is to make your site as discoverable and accessible as possible for users searching Google and other search engines in their local language. 

  It’s worth pointing out that multilingual SEO differs slightly from international SEO, even if the terms are used interchangeably. With multilingual SEO, you are optimising for a language (so Spanish targets every Spanish-speaking country, not just Spain). In international SEO, you target specific countries, so you might have a different strategy for targeting Argentinian customers vs. Mexican customers. 

  Why adopt a multilingual SEO strategy ?

  There are two major reasons to adopt a multilingual SEO strategy : to reach more customers and to deliver the best experience possible. 

  

  Reach a wider audience

  Not everyone searches the web in English. Even if non-native speakers eventually resort to English, many will try Googling in their own language first. That means if you target customers in multiple non-English-speaking countries, then creating a multilingual SEO is a must to reach as many of them as possible. 

  A multilingual SEO strategy also boosts your website’s chances of appearing in country-specific search engines like Baidu and Yandex — and in localised versions of Google like Google.fr and Google.de.

  Deliver a better user experience

  Multilingual SEO gives your customers what they want : the ability to search, browse and shop in their native language. This is a big deal, with 89% of consumers saying it’s important to deal with a brand in their own language.

  Improving the user experience also increases the likelihood of non-English-speaking customers converting. As many as 82% of people won’t make a purchase in major consumer categories without local language support. 

  How to prepare for multilingual SEO success

  Before you start creating multilingual SEO content, you need to take care of a couple of things. 

  Identify target markets

  The first step is to identify the languages you want to target. You know your customers better than anyone, so it’s likely you have one or two languages in mind already. 

  But if you don’t, why not analyse your existing website traffic to discover which languages to target first ? The Locations report in Matomo (found in the Visitors section of Matomo’s navigation) shows you which countries your visitors hail from. 

  

  In the example above, targeting German and Indonesian searchers would be a sensible strategy. 

  Target local keywords

  Once you’ve decided on your target markets, it’s time to find localised keywords. Keywords are the backbone of any SEO campaign, so take your time to find ones that are specific to your local markets.

  Yes, that means you shouldn’t just translate your English keywords into French or Spanish ! French or Spanish searchers may use completely different terms to find your products or services. 

  That’s why it’s vital to use a tool like Ahrefs or Semrush to do multilingual keyword research. 

  

  This may be a bit tricky if you aren’t a native speaker of your target language, but you can translate your English keywords using Google Translate to get started. 

  Remember, search volumes won’t be as high as English keywords since fewer people are searching for them. So don’t be scared off by small keyword volumes. Besides, even in the U.S. around 95% of keywords get 10 searches per month or fewer. 

  Choose your URL structure

  The final step in preparing your multilingual SEO strategy is deciding on your URL structure, whether that’s using separate domains, subdomains or subfolders. 

  This is important for SEO as it will avoid duplicate content issues. Using language indicators within these URLs will also help both users and search engines differentiate versions of your site. 

  The first option is to have a separate domain for each target language. 

  • yoursite.com
  • yoursite.fr
  • yoursite.es

  Using subdomains would mean you keep one domain but have completely separate sites :

  • fr.yoursite.com
  • es.yoursite.com
  • de.yoursite.com

  Using subfolders keeps everything clean but can result in long URLs :

  • yoursite.com/en
  • yoursite.com/de
  • yoursite.com/es

  As you can see in the image below, we use subdomains to separate multilingual versions of you site :

  

  While separate domains provide more precise targeting, it’s a lot of work to manage them. So, unless you have a keyword-rich, unbranded domain name that needs translating, we’d recommend using either subdomains or subdirectories. It’s slightly easier to manage subfolders, but subdomains offer users a clearer divide between different versions of your site. 

  If you want to make your site even easier to navigate, then you can incorporate language indicators into your page’s design to make it easy for consumers to switch languages. These are the little dropdown menus you see containing various flags that let users browse in different languages.

  5 multilingual SEO strategies to use in 2024

  Now you’ve got the basics in order, use the following SEO strategies to improve your multilingual rankings. 

  Use hreflang tags

  There’s another way that Google and other search engines use to determine the language and region your website is targeting : hreflang..

  Hreflang is an HTML attribute that Google and other search engines use to ensure they serve users the right version of the page.

  You can insert it into the header section of the page like this example for a German subdomain :

  <link rel=”alternate” href=”https://yourwebsite.com/de” hreflang=”de” />

  Or you can add the relevant markup to your website’s sitemap. Here’s what the same German markup would look like :

  <xhtml:link rel=”alternate” hreflang=”de” href=”https://yourwebsite.com/de/” /> 

  Whichever method you include one language code in ISO 639-1 format. You can also include a region code in ISO 3166-1 Alpha 2 format. Note that you can include multiple region codes. A web page in German, for example, could target German and Austrian consumers. 

  Hreflang tags also avoid duplicate content issues. 

  With a multilingual site, you could have a dozen different versions of the same page, showing the same content but in a different language. Without an hreflang tag specifying that these are different versions of the same page, Google may penalise your site.

  Invest in high-quality translations

  Google rewards good content. And, while you’d hope Google Translate would be good enough, it usually isn’t.

  Instead, make sure you are using professional linguists to translate your content. They won’t only be able to produce accurate and contextually relevant translations — the kind that Google may reward with higher rankings — but they’ll also be able to account for cultural differences between languages. 

  Imagine you are translating a web page from U.S. English into Italian, for example. You’ve not only got to translate the words themselves but also the measurements (from inches to cm), dates (from mm/dd/yy to dd/mm/yy), currencies, idioms and more. 

  Translate your metadata, too

  You need to translate more than just the content of your website. You should translate its metadata — the descriptive information search engines use to understand your page — to help you rank better in Google and localised search engines. 

  As you can see in the image below, we’ve translated the French version of our homepage’s title and meta description :

  

  Page titles and meta descriptions aren’t the only pieces of metadata you need to pay attention to. Make sure you translate the following :

  • URLs
  • Image alt tags
  • Canonical tags
  • Structured data markup

  While you’re at it, make sure you have translated all of your website’s content, too. It’s easy to miss error messages, contact forms and checkout pages that would otherwise ruin the user experience. 

  Build multilingual backlinks

  Building backlinks is an important step in any SEO strategy. But it’s doubly important in multilingual SEO, where your links in your target language also help Google to understand that you have a translated website. 

  While you want to prioritise links from websites in your target language, make sure that websites are relevant to your niche. It’s no good having a link from a Spanish recipe blog if you have a marketing SaaS tool. 

  A great place to start is by mining the links of competitors in your target market. Your competitors have already done the hard work acquiring these links, and there’s every chance these websites will link to your translated content, too.

  

  Don’t forget about internal linking pages in the same language, either. This will obviously help users stay in the same language while navigating your site, but it will also show Google the depth of your multilingual content.

  Monitor the SEO health of your multilingual site

  The technical performance of your multilingual pages has a significant impact on your ability to rank and convert. 

  We know for a fact that Google uses page performance metrics in the form of Core Web Vitals as a search ranking factor. What’s more, research by WP Rocker finds that a side loading in one second has a three times better conversion rate than a site loading in five seconds. 

  With that in mind, make sure your site is performing at optimal levels using Matomo’s SEO Web Vitals report. Our SEO Web Vitals feature tracks all of Google’s Core Web Vitals, including :

  • Page Speed Score
  • First Contentful Paint (FCP)
  • Final Input Delay (FID)
  • Last Contentful Paint (LCP)
  • Cumulative Layout Shift (CLS)

  The report displays each metric in a different colour depending on your site’s performance, with green meaning good, orange meaning average, and red meaning poor.

  

  Check in on these metrics regularly or set up custom alerts to automatically notify you when a specific metric drops below or exceeds a certain threshold — like if your Page Speed score falls below 50, for example. 

  How to track your multilingual SEO efforts with Matomo

  Matomo isn’t just a great tool to track your site’s SEO health ; you can also use our privacy-focused analytics platform to track your multilingual SEO success.

  For example, you could use the report to focus your multilingual SEO efforts on a single language if searches are starting to rival English. Or you decide to translate your most trafficked English keywords into your target languages, regardless if a tool like Ahrefs or Semrush tells you whether these keywords get searches or not.

  If you want to analyse the performance of your new language, for example, you can segment traffic by URL. In our case, we use the segment “Page URL contains fr.matomo.org” to measure the impact of our French website. 

  We can also track the performance of every language except French by using the segment “Page URL does not contain fr.matomo.org”.

  You can use Matomo to track your Keyword performance, too. Unlike search engine-owned platforms like Google Analytics and Google Search Console that no longer share keyword data, Matomo lets users see exactly which keywords users search to find your site in the Combined keywords report :

  

  This is valuable information you can use to identify new keyword opportunities and improve your multilingual content strategy. 

  For example, you could use the report to focus your multilingual SEO efforts on a single language if searches are starting to rival English. Or you decide to translate your most trafficked English keywords into your target languages, regardless if a tool like Ahrefs or Semrush tells you whether these keywords get searches or not.

  For international brands that have separate websites and apps for each target language or region, Matomo’s Roll-Up Reporting lets you keep track of aggregate data in one place. 

  

  Roll-Up Reporting lets you view data from multiple websites and apps as if they were a single site. This lets you quickly answer questions like :

  • How many visits happened across all of my multilingual websites ?
  • Which languages contributed the most conversions ?
  • How does the performance of my Spanish app compare to my Spanish website ?

  Is it any wonder, then, that Matomo is used by over one million sites in 190 countries to track their web and SEO performance in a privacy-friendly way ?
