As I was saying on my SEO page, I no longer care about Page Ranking.
I have many links to WikiPedia and W3C Schools. The reason for this as I find that they are both good sources of information that is relevant to my pages. In all cases when I make a link to a website that I do not own or control I do so in a manner so as not to assign any endorsement of that website.
How I now construct an External Link
The use of a rel="nofollow" and a 🔗 symbol (the code for which is: 🔗)
