1,500 links in all. Must be a great resource, right?
No, not really.
If you look closely at the green SEO section the advice is stuff like:
Do lots of link building!
Architect your site for search
Set up webmaster tools
Really, the content itself is "lackluster" to put it nicely.
But just look at the graphic. To say it's "eyecatching" is an understatement. It's beautiful. The colors, the data visualization. 10/10 on looks.
The takeaway is simple: If your content is shit, make sure it at least looks amazing.
