Top 6 Google Analytics Features for Beginners

Google Analytics is quite crammed with options, making it hard to find the useful ones. Here’s a list of the most useful features from the reporting tab, the most important one for starting.

#6 Dashboard

Somewhat hidden under Dashboards > Private > My Dashboard you’ll find the following metrics:

Screen Shot 2016-05-14 at 22.13.28

This gives you a good overview over your users. You see how many new users you’re gaining and how many you have in total and where they’re located. About the bounce rate you shouldn’t worry too. I’d stay clear of focusing too much on improving it, as it will improve naturally if you just provide an interesting page.

#5 Behaviour Flow

Screen Shot 2016-05-14 at 22.07.16

This view can be found under Behaviour > Behaviour Flow. This is interesting, if you have a complex website and you want to reduce the number of clicks a user needs to get to his or her goal.

#4 Pages

Here you can see which pages are doing best:

It’s found under Behaviour > Site Content > All Pages. This lets you know where you have done an exceptionally good job and what still needs improvement.

#3 Heat Map

In order to see which buttons get used on your page, it’s useful to install the Page Analytics (by Google) plugin for the Chrome Browser.Screen Shot 2016-05-14 at 23.35.07

Using this feedback, you can optimize your website by removing buttons that never get clicked anyways, or position important links more prominently.

#2 Audience Overview (Default Screen)

Screen Shot 2016-05-14 at 22.23.23

Google Analytics sets the default screen to Audience > Overview. Here you can gain a quick overview over what’s happening on your site. Of course you’ll want Sessions and Users to increase. That’s the page you’ll get addicted to, in order to see whether traffic on your page is increasing.

#1 Connecting Search Console with Google Analytics

A really useful screen is Acquisition > Search Console > Queries. But before this will work, you’ll need to connect your search console with Google Analytics. If you don’t have you’re site registered in google search console, you have to do so first. That’s important to be found on Google in any case.

Once you have established the connection, you can see which queries resulted in an impression of your website on Google and how often the search result was clicked:

Screen Shot 2016-05-14 at 23.10.42

So for this page, you see that some impressions were displayed, but none were clicked, which will hurt the ranking in the future. The (not set) is explained by Google like so:

To protect user privacy, queries made a very small number of times or containing personal or sensitive information are grouped as “(not set)”.

It’s possible that the view is not entirely up to date:

No data is available for the 2 most recent days.

Screen Shot 2016-05-15 at 15.33.04

The SEO view is so important, because it lets you know where you rank good on Google and where you could improve. For example, if something has 100 impressions but no clicks, you might consider putting a better description on the page. Or when you already rank good in “bla” for a page, you might consider to optimize the page even more for “bla” so it’ll get to Google page one, increasing your user numbers.

Best WYSIWYG Editor for Web-Content

Logos of different WYSIWYG editors for web content / html

UPDATED: June 2017

There are different out-of the box wysiwyg’s for the web. Prominent exponents of web-html-wysiwyg’s are the CKEditor or the TinyMCE. Paid (yet still extendable) solutions include Froala and Redactor. Which one’s right for you?

TL;DR: If you’re commercial, use the Froala Editor. If you’re not or need an open source editor use TinyMCE.

Here’s a more comprehensive breakdown of all editors.


The CKEditor is the most broadly adopted Wysiwyg editor nowadays. Google trends confirms this compared to it’s main competitor TinyMCE. Yet, I completely do not understand how it got there. It’s quickly installed, I’ll give it that much. But the developers seem not to have the slightest clue about design or usability. Here’s how it looks like:

CK Editor Screenshot

It looks very heavy and old-fashioned. But the problem really starts when looking at the more complex features. Like inserting a table.

CK Editor Table Insertion

I think this interface speaks for itself.

The next atrocity follows once you have the table input inserted:

CKEditor Tables

Yes, I know this is how browsers render tables by default, but couldn’t the editor somewhat ease the pain? Every other editor I found doesn’t display it like this.

Anyways, let’s move on and insert an image:

CKEditor Image Insertion

Again, we are confronted with a beautifully designed dialog. Not. I don’t want to waste anymore space, so I’ll not post more CKEditor popup dialogs. So what are the good parts about the CKEditors? Well, there are plugins, it’s customizable and it’s got broad adoption so you’ll find some help for your problems on the interwebz.

One other thing I noticed, is that CK is more aggressively converting your input than other editors. For example a tick (‘) is left alone by most editors, while CK converts it to '. Whether you find this good or bad depends on what you want. By the way, did you know that the CKEditor used to be the FCKEditor named after it’s creator Frederico Caldeira Knabben, but then they noticed fck is too close to f*ck?


Ah, away from the horrors that is the CKEditor and onwards to adventures with TinyMCE. The name means it was “Tiny Many Centuries Earlier”. Which is not that bad, computers get faster, but some people in the community don’t like it.

So at first sight TinyMCE looks nicer than the CKEditor.

TinyMCE Screenshot

I understand most of it’s elements as only the common ones are itemized and for the others they use dropdown menu’s and text-labels. If you haven’t given this too much thought, here’s why this is a good move. Let’s continue by inserting a table:

TinyMCE Table Insertion

What I like about it, is the grid-selection of the table size. What I don’t like about it is, that it show’s 1 option which is clickable and 5 options which aren’t.

TinyMCE useless buttons

Why is it showing this to me? Well anyways, this is a detail. Afterwards, the inserted table looks nice and I get options to edit it:

TinyMCE table editing

So all-in-all the TinyMCE table experience is satisfactory but not overwhelming. Let’s perform an image upload next. Oh that’s right, I can’t. I can only link a URL where my image is. That’s really handy of course, since I always upload my images first to another server, before using them on the actual platform! Great!

TinyMCE image insertion

Of course, for any image upload to a server, the editor can’t do it by itself, but I think it should at least provide the interface and explain how you can wire it to your server.  I tried to Google for a workaround, but wasn’t finding anything fast, which is usually a bad sign. On the other hand, I’m sure there are things and even if there are not, adding a “Add Media” button yourself won’t be too hard. Actually, WordPress does it like that:

Wordpress Add Media Button

They use the TinyMCE with an external button to upload media. So if TinyMCE is good enough for WordPress, it will surely be good enough for you? Well, consider that WordPress has been around for quite a while and so has TinyMCE and it thus just might be a legacy choice. Also, WordPress has to use open source code in order to be able to distribute it. The next option will be a paid one, so if your solution doesn’t need to be open source, you might consider it.


Ahh isn’t this a bliss? Start’s really nicely. Until you notice it’s not free.

Well, can I still customize it? Yes, you can. You can write plugins for this editor, as well as for CK or TinyMCE. The only difference is that it will make you between $99 and $799 poorer, while looking better. Let’s see whether the table feature and images are implemented better than in CK or TinyMCE. That’s really the anything hard for a wysiwyg anyways. Making something bold I could even do myself… So, tables:

Froala Table Insertion

That’s all I need for inserting! Thank you! Editing tables:

Screen Shot 2016-05-12 at 01.42.58

I can only say one thing: Very sophisticated and thought through. Borders are draggable and stylable and individual cells are even colorable.

Froala Tables

What about images?

Froala Image Insertion

YES, this is what I need! First priority: UPLOAD. If you really want to, then fine, click that darn link so you can insert an image by URL. How does it look like once it’s inserted?

Froala Image Editing Part 1Froala Image Editing

Wow, I can resize it and everything! That’s just great.

I want to conclude the summary about Froala with a statement that I’m not affiliated with them or their product. Simply the frustration about CK and Tiny got me to be so excited about something that will cost you 800 bucks for commercial use. Following are some more editor’s, just not described as in detail anymore.


I wrote this review originally about Froala Editor v1. Now they have released a v2, and it’s even better. We’re now using the Froala Editor in our product Taskbase including customizations. Their API is intuitive and it was a joy to work with it. With only 300 lines of code I managed to strap together a math plugin, gap text plugin and a special list feature. All the options of the editor are well documented and useful. They found a good balance between powerful features yet not overloading the editor and it is really well designed (code as well as layout). When you buy the editor, you can download the full source code. However, I would not recommend you to “hack their core” (google hacking core if you haven’t heard of this), but instead to write plugins. This way you’re sure to stay compatible with their updates.


Next to Froala, there is another paid wysiwyg editor. It’s called Redactor. Redactor has less features than Froala. They only allow for full-width images and full-width tables. Furthermore tables cannot be stacked into each other or customized. Those restrictions might be exactly what some people are looking for.

Redactor Screenshot

However, I think even if you want a simplistic editor Froala is the better choice. You may easily take out a lot of functionality out of Froala (e.g. not displaying a file upload button or a change-color button) but once you decide afterwards you want those things anyhow, you’ll be damn glad the editor already has them and you don’t have to program it yourself!


Screenshot of the QuillJS editor

QuillJS is a a nice option if you want an editor that works without JQuery, for example if you need to use the ShadowDOM. It’s an open source project you can find on Github at with over 13k stars.

On the downside it doesn’t offer extended functionality like for example tables.


While ContentToolsJS also has a strong focus on beauty, it throws overboard quite a lot of the classical editor notion. Their editor just dangles in the air, which I imagine could become a problem on mobile phones? Also I couldn’t find anything about cusomizability, so I expect that I couldn’t write any plugin for it. Last but not least, let’s inspect our favourite quality give-away element, the table:

ContentToolsJS Screenshot

It’s not customizable at all and always equidistant (here ⅓, ⅓,⅓ ). So if you Have a lot of text in let’s say column two and three and only labels in column one, then you’re “the former name of ck-editor-ed”


While all the other editors discussed so far were HTML editors, let’s review a markdown editor for a change. It’s easier to write a markdown editor because it’s only a subset of the html features, but on the other hand you’ll have to live with those restrictions afterwards. SimpleMDE has done a good job with bold, italics, headings and so on. As usually. It’s left out tables even though those would be supported by Markdown. Shame on you SimpleMDE! Still the best Markdown-Almost-Wysiwyg out there.

SimpleMDE Screenshot

Other Editors

I’ve tried a bunch of other editors like Trubowyg, textAngular or Summernote. I’ll just say they didn’t really convince me and leave it at that. Choose Froala and go out and play rather than reading about more editors!

Just for fun: If you want to see how Wikipedia does it, you can! Just click on “edit” in Wikipedia. For the German pages, they have a quite elaborate editor catering to almost any need:

Wikipedia Editor Screenshot


I wouldn’t have thought it’s so damn hard to find a decent wysiwyg in 2016. But apparently it is. If you need an open source solution and can’t spare a few bucks, TinyMCE is the best option. If you don’t mind spending a little money or it would be more expensive for you to program your custom “Add Media” button, choose Froala. If you don’t want to take my word for it, here’s another review.

MathJax vs KaTeX vs MathML vs Latex2Img


There is a multitude of options to display mathematics on the web including MathJax, Katex, MathML and Latex2Image. Which one is right for you?

TL;DR: Choose Mathjax.


Mathjax can work with latex or mathml input, then sends the code to the mathjax library which renders a “mathjax element”. This is a svg with fonts, which can also be copy pasted (right click). Are there limitations? Mathjax can render most of the “standard” Latex. So as long as your users don’t wanna go too crazy (e.g. tikz or some other specialized library), you’re fine with Mathjax. The major advantage is that it’s svg and thus looks “beautiful”, and you also do not need to compile every equation yourself. Often you’ll read that mathjax is a bit slow. But I found that even with lots and lots of math on the page, it would render fast.

The idea behind mathjax is not to do everything with mathjax, but to leave things like bold-font and italic to the html and only cover the mathematics of the page.

For example in Latex, you’d write:

Hello \textbf{World}, let's do some math: $\frac a b = c$

whereas in mathjax the equivalent for this is:

Hello <b> World </b>, let's do some math: $\frac a b = c$

Notice how the bold font is just regular html, it has nothing to do with mathjax. Mathjax only covers the mathematics on the page.

Mathjax keeps things nice and simple, you can choose delimiters for inline math (e.g. $ to start and $ to end as we’re used from latex) and for “display-math” (meaning a centered block element).

It’s very easy to get started with it, just import the mathjax library and optionally configure the mathjax object. Mathjax will do the rendering from there. Here’s an example config for the mathjax object:

  tex2jax: {
    inlineMath: [['$','$'],['\\(','\\)']],
    displayMath: [['$$','$$'],['\\[','\\]']],
    balanceBraces: true,
    processEscapes: true,
    processRefs: true,
    processEnvironments: true,
    ignoreClass: "no-mathjax"
  TeX: {
    equationNumbers: { autoNumber: "AMS" },
    extensions: ["[Contrib]/siunitx/unpacked/siunitx.js"],
    Macros: {
      mustbe: "\\overset{!}{=}",
      RR: "\\mathbb{R}",
      ZZ: "\\mathbb{Z}",
      NN: "\\mathbb{N}",
      QQ: "\\mathbb{Q}"

Here are the cornerstones explained:

  • inlinemath, displaymath: Delimiters for mathematics. Note that $ some math $ is NOT the default for inline-math, the default is \( some math \)!
  • ignoreClass: For example if you want to parse your entire page for mathematics except some parts, you can exclude those parts by surrounding them with the css-class specified in ignoreClass.
  • Macros: Macros as you’d know them from Latex
  • extensions: In case default Mathjax isn’t enough, it’s also possible to use (or write) additional extensions

Finally, here’s an example of some rendered Mathjax inline \( \int_0^\infty x^2\) and block \[\sum_{n=0}^3 n-3 = … \]


While with Mathjax there seem (almost) no Latex features missing, KaTeX can’t render a number of equations such as \overrightarrow{AB} or aligned equations. This disqualifies Katex for the moment being. Once it hosts a more comprehensive latex-feature set, it becomes a viable alternative to Mathjax, because it renders much faster. However, we never experienced any problems with the speed of mathjax, so I don’t really see the need.


The advantage of MathML is, that it can be interpreted by the browser. So for example, when you write <math xmlns=”“><mfrac><mn>1</mn><mn>2</mn></mfrac></math> into your html, the browser will display ½. Actually, let’s rather say it should, since it doesn’t work e.g. with Chrome Browser but does work with firefox. When you type $\frac 1 2$, the browser will display $\frac 1 2$ (unless you use mathjax). Overall, it can be said that this is a very shaky way to display your math and I don’t see any reason to do so.

A look at Google trends reveals, that MathML is clearly de-trending and being surpassed by Mathjax.

Converting Latex to image (png,svg,…)

That’s the way Wikipedia does it. On the downside, you’ll have to handle all the scaling and storing of images yourself. On the upside, there isn’t anything from latex, that can’t be rendered, and it’s fast. There are also two possibilities here: Either you only compile equations or you compile the entire thing. Compiling the entire thing is rather bad, since it’s not scalable width wise and all the text is not selectable anymore.

Bonus Option: Mixed

Since Mathjax perfectly handles most of the latex, it can be safely used for displaying math of a web page, for example together with a wysiwyg editor. However, sometimes you want to have the crazy latex stuff like tikzpictures anyways. There’s nothing wrong with combining mathjax and latex2image. You can handle the simple math with Mathjax and the the advanced latex stuff with a “latex” plugin for your wysiwyg editor.

Here’s what this could look like:

Bla bla bla it’s still html now some mathjax \(\frac a b = c\) and for the complex stuff latex2img like here:



It’s a close race between Mathjax and compiling equations with latex to png’s and displaying them as images. I would recommend the Mathjax option, since Mathjax has gained wide support and will improve over time and saves development time. Also, when done correctly, Mathjax rendering can be quite fast.

To be sure not to make the wrong decision, take an example from

You will need a running ubuntu server to follow the steps in this article.


  1. Enter in terminal:
    sudo apt-get update
    sudo apt-get install apache2 apache2-utils
    sudo htpasswd -c /etc/apache2/.htpasswd some-username
    sudo nano /etc/apache2/sites-enabled/000-default.conf
  2. Add:
    <Directory "/var/www/html">
            AuthType Basic
            AuthName "Restricted Content"
            AuthUserFile /etc/apache2/.htpasswd
            Require valid-user

    Replace /var/www/html with the path to the directory you want to restrict access to.

  3. sudo service apache2 restart


Host Static Files with Apache on Digitalocean

1. Setup Digital Ocean Server

Login or create an account and spin up a new ubuntu 14.04 droplet at, it is pretty self explanatory. In the options, you should choose login through SSH if you want to follow this article step by step.

Then login to your Server:
ssh root@<yourIp> (e.g. ssh root@

2. Install Apache

sudo apt-get update
sudo apt-get install apache2
When you type <yourIp> into your browser (e.g. Screen Shot 2016-04-29 at 12.12.09), you should now be able to see the following:
Screen Shot 2016-04-29 at 12.10.23

3. Change index.html

Now “hosting static files” can mean two things. Either you want to host something like mycoolfile.txt or you want a classic website.

Option 1: Host files for downloading

  1. Switch directory to cd /var/www/html and remove the index.html file (rm index.html)
  2. Copy the files to your server. Navigate to the directory containing your file in a new terminal window and scp mycoolfile.txt root@<yourIp>:/var/www/html.

You should see the following result when navigating to yourIp in your browser:

Screen Shot 2016-04-29 at 12.40.03

Option 2: Host your personal website

  1. Switch directory to cd /var/www/html and remove the index.html file (rm index.html)
  2. Then nano index.html. Then you can write any valid html, for example:
    <!DOCTYPE html>
    <h2>Much Doge! Wow!</h2>
    <img src="" alt="Doge" width=300px>

    which should yield:

Install SSL certificate through letsencrypt on nginx

The days of expensive SSL Certificates are over. Letsencrypt is rapidly changing the way certificates are handled. The basic functionality is that you install the letsencrypt client on your server and from there it does its magic to authenticate your server. They also offer a lot of automation tools, which might scare you at first. But it’s really easy to get certificates and install them e.g. with nginx. Here’s how, assuming you have nginx installed on an ubuntu server.

1) Go to your registrar and point your site, e.g. to your servers IP e.g.

2) Login to your server (ssh root@ on digital ocean for example), then:

git clone
cd letsencrypt
./letsencrypt-auto certonly --standalone --email -d -d
cd /etc/nginx/ssl/
ln -s /etc/letsencrypt/live/ nginx.key
ln -s /etc/letsencrypt/live/ nginx.crt

3) Use the following inside your http block of the nginx.conf file:

  upstream project {
    server localhost:8080;

  server {
    listen  80;
    return  301 https://$host$request_uri;

  server {
    listen 443 ssl;
    ssl_certificate /etc/nginx/ssl/nginx.crt;
    ssl_certificate_key /etc/nginx/ssl/nginx.key;
    ssl_protocols TLSv1.2 TLSv1.1 TLSv1;

    location / {
      proxy_pass http://project;
      proxy_read_timeout 1000;

4) service nginx reload and enjoy.


How to setup www vs non-www, http vs https for SEO

When learning about SEO, you have probably read that you should only use www or non-www and only http or https. This begs the question: What does “only” even mean? Does it mean in all your blogs and PR events you must link consistently to or is a forward from to good enough? My research for this suggests that a forward is enough and you do not need to worry, as long as you register all the versions of your site in the Google Search Console.

Nowadays if you have a somewhat potent webapp, you probably need users to login and therefore you need SSL (https). Whether you use www or non-www doesn’t matter as long as you are consistent. redirects to www and stackoverflow redirects to non-www, so you have examples of two sites that are good at SEO with different settings.

Now lets say we want to setup our www https page. What we can’t do is a 301 permanent redirect on the registrar, since they can’t redirect https non-www. So we will have to write the redirects on our own servers. So in the end we will have:

A record: @ pointing to <my_IP>
CNAME alias: www pointing to @

while the redirects non-www to www and http to https happen on the server. Here is an example for how to redirect from http to https using nginx.
