  • Your 6-step guide to increasing acquisition

    2 juillet 2019, par Matomo Core Team — Analytics Tips

    Your 6-step guide to increasing acquisition

    Want to save time and money, as well as increase conversions and acquisition ? Matomo Analytics is here to help with that !

    Let’s start by helping you create a website visitors’ acquisition strategy, without it you might be going in blind and missing opportunities that might’ve been easily found in your metrics.

    To help you craft a strategy for your site, check out the steps below !

    Step one : Get familiar with the Acquisition feature

    The easiest way is to start with Matomo’s Acquisition feature itself. Discover and take action on the marketing channels with the biggest ROI for your business. You’ll learn :

    How to get traffic from external websites : Find out who’s helping you succeed from external websites and convince them to do more of it. Get more traffic by proactively asking for : paid sponsorships ; guest blog posts ; or spending more advertising on the particular website.

    About Social Networks : Which social media channels are connecting with the audience you want ? Take the guesswork out by using only the ones you need. By finding out which social channels your ideal audience prefers, you can generate shareable, convincing and engaging content to drive shares and traffic through to your site.

    Campaigns : This helps you understand which marketing campaign is working and which isn’t. You can then shift your efforts to effectively gain more visitors with less costs. Keep track of every ad and content piece you show across internal and external channels to see which has the biggest impact on your business objectives.

    Enhanced SEO : Every acquisition plan needs a focus on maximising your Search Engine Optimization (SEO) efforts. When it comes to getting conclusive search engine referrer metrics, you need to be sure you’re getting ALL the insights to drive your SEO strategy. See keyword position rankings, integrate Google, Bing and Yahoo search consoles, and no longer be restricted with “keyword not defined” showing up in your keywords reports.

    Step two : Set your goals and monitor conversion funnels

    Let the Goals feature guide you

    Goals are essential for building your marketing strategy and getting new customers. The more goals you track, the more you learn about behavioural changes and modify pathways to impact acquisitions over time. 

    Are you checking :

    • Which channels are converting the best for your business ?
    • Which cities/countries are most popular ?
    • What devices will attract the most visitors ?
    • How engaged your visitors are before converting ?

    This way you can see if your campaigns (SEO, PPC, signups, blogs etc.) or optimising efforts (A/B Testing, Funnels) have made an impact with the time and investment you’ve put in.

    The Funnels feature leads you to success

    Conversion funnels give you the big picture on whether your acquisition plans are paying off and where they may be falling short. If the ultimate goal of your site is to drive conversions, then each funnel can tell you how effectively you’re driving traffic through to your desired outcome.

    Step three : Measure the success of every touchpoint in your customer’s journey

    Multi Attribution feature

    Accurately identify channels where visitors first engage with your business, as well as the final channel they came from, before purchasing your product/service. This helps you make smarter decisions when determining acquisition spend to accurately calculate the Customer Acquisition Cost (CAC). Here you no longer falsely over-estimate investment in failing marketing channels.

    Step four : For ecommerce sites, understand who your customers are to increase sales

    Ecommerce feature to significantly increase $ potential

    If your website’s overall purpose is to generate revenue, the Ecommerce feature gives you comprehensive insights into your customer’s purchasing behaviours.

    This heavily reduces your risks when marketing products to potential customers as you’ll understand who to target, what to target them with and where further opportunities exist.

    e-commerce analytics

    Step five : Make sure the forms on your website are easy to complete

    Form Analytics feature

    Once you get visitors through the funnel, the forms on your website are the final step to conversion and need special attention. If not done right, you could be missing out on converting a large portion of your visitors.

    Thankfully, you can now identify and fix pain points on the forms that are most important to your business’ success.

    Step six : Discover what a customer journey looks like on a user-by-user basis and bring in key acquisition elements to your strategy

    Visitor Profiles tell you each visitors’ history

    The Profile feature summarises every visit, action and purchase made.

    Better understand :

    • Why your visitors viewed your website.
    • Why your returning visitors continue to view your website.
    • What specifically your visitors are looking for and whether they found it on your website.

    The benefit is being able to see how a combination of acquisition channels play a part in a single buyer’s journey.

  • Pipe a HTTP response

    30 juillet 2014, par viperfx

    How do I pipe an HTTP response like in NodeJS. Here is the snippet I am using in NodeJS :

    request({
     url: audio_file_url,
    }).pipe(ffmpeg_process.stdin);

    How can I achieve the same result in Go ?

    I am trying to pipe a audio stream from HTTP into an FFmpeg process so that it converts it on the fly and returns the converted file back to the client.

    Just so its clear to everyone here is my source code so far :

    func encodeAudio(w http.ResponseWriter, req *http.Request) {
       path, err := exec.LookPath("youtube-dl")
       if err != nil {
           log.Fatal("LookPath: ", err)
       }
       path_ff, err_ff := exec.LookPath("ffmpeg")
       if err != nil {
           log.Fatal("LookPath: ", err_ff)
       }

       streamLink := exec.Command(path,"-f", "140", "-g", "https://www.youtube.com/watch?v=VIDEOID")

       var out bytes.Buffer
       streamLink.Stdout = &out
       cmdFF := exec.Command(path_ff, "-i", "pipe:0", "-acodec", "libmp3lame", "-f", "mp3", "-")
       resp, err := http.Get(out.String())
       if err != nil {
           log.Fatal(err)
       }
       // pr, pw := io.Pipe()
       defer resp.Body.Close()
       cmdFF.Stdin = resp.Body
       cmdFF.Stdout = w
       streamLink.Run()
       //get ffmpeg running in another goroutine to receive data
       errCh := make(chan error, 1)
       go func() {
           errCh <- cmdFF.Run()
       }()

       // close the pipeline to signal the end of the stream
       // pw.Close()
       // pr.Close()

       // check for an error from ffmpeg
       if err := <-errCh; err != nil {
           // ff error
       }
    }

  • Fix CBR output for IP multicasting video

    19 août 2014, par ddhung

    I’m using ffmpeg for transcoding live ip multicasting video on server linux Centos 5.9 OS. This is my ffmpeg command

    ffmpeg -i "udp:// x.x.x.x:6000?fifo_size=1000000&overrun_nonfatal=1&timeout=1000000" -filter:v yadif=0:-1:1 -vcodec libx264 -vprofile main -level 30 -tune zerolatency -pass 1 -b:v 900k -minrate 900k -maxrate 900k -bufsize 900k -x264opts nal_hrd=cbr:rc_lookahead=40:interlaced=1:scenecut=0:cabac=1:keyint=120:deblock=0,0:aud=1:qpmin=16:qpmax=51:qpstep=10:ref=2:mixed-refs=1:subme=9:me=esa:chroma_me=0:merange=64:8x8dct=0:fast_pskip=0:chroma_qp_offset=0:trellis=2:psy=0:bframes=0:weightp=2:sliced_threads -s:v 720x576 -r:v 25 -force_key_frames 'expr:gte(t,n_forced*3)' -threads 0 -acodec aac -strict -2 -ac 1 -ar 32000 -b:a 32k -filter:a volume=1 -f mpegts -muxrate 1400k udp://x.x.x.x:6000?pkt_size=1316

    My output video is for broadcasting so I have to configure CBR video output by feature –muxrate. But when I watch this stream on VLC the bitrate change very much not constant. The null packet is very high to force cbr mpeg2ts output.

    I also measure IP output video by HST3000 JDSU equipment and I see the measurement result is very bad as images.
    The PCR Jitter, IGMP Latency, Jitter Max which is not good as measurement standard by JDSU

    I try many way to change the ffmpeg command but not successful. The bitrate changes sometime > 1400kbps a lot. I think the problem may be the bitrate not constant. I have heard to change the muxrate output is CBR, it had to be change the code C mpegtsenc.c in libavformat library to new patch.
    So could you help me fix this problem and make the measurment result is better.
    Thank you so much.

    Best Regards
