So the guy who brought the world supernovae and neutron stars also discovered and named the concept of "dark matter" in 1933. Interestingly, he also coined the term "spherical bastard" for someone who is a bastard no matter which way you look at them. Fritz Zwicky had jokes. 😀 In spite of his considerable contributions to science, most of us have never heard of him. There's speculation that it's because the term he coined may also have been self-descriptive. 🤷🏽♀️
Nevertheless, scientists tested his dark matter theory and today in 2006, released the strongest direct evidence that it actually exists. While other telescopes like Hubble, the Very Large Telescope, and Magellan were measuring the matter we can see, the then-new Chandra X-ray telescope helped us understand how much total matter actually exists, and when you compare the two, something weird happens. There are huge gaps. Basically, we can deduce the existence of FAR more matter than we can actually see in all the wavelengths of light that we know about. 👀The "missing" matter that we can't see is what we call dark matter.
In compiling this proof, no single telescope did everything. Each had its own purpose.
SEO works through a similar division of labor.
On Monday we asked:
How many keywords should you focus on for SEO?
The answer: Match one primary keyword to each significant page or page group.
While your website can have many keywords, each page should have its own SEO purpose, just like each telescope did. When you put all the pages together, you hopefully are able to rank for a variety of searches that bring qualified customers to your site.
