When I decided to create and manage my own web pages I was tempted by a local college of technology evening class.
Sadly I discovered that the fruit of Blair's meetings with Bill Gates was that what they taught was how to use the Microsoft product, not about web design in general nor anything about SEO etc. Also, since the course tutor seemed to be only one page ahead of everyone else I dropped out and bought myself Serif Web Plus (they have free simplified versions available)
Web plus does let you capture an existing site (more or less complete)and I have my old site stored.
What is concerning are the antics of Google. I am far from pleased with their search engine nor with their "characterisation" of searches personalised to your previous browsing history and even less enchanted by the news that AT&T etc, the US cable companies, are presently trying to get the law changed so that can charge different rates. Not sure I understand all of this except that it means that those who can pay will always be top of the searches along with paid for adverts and the rest of us will drop out of the first few search pages, if we ever managed to get there, and will quickly sink into oblivion.
Occasionally I do vanity searches on Google. What makes the first 6 pages might affect how someone views me in the world. Up till about a year ago, my comments from numberwatch, jref, and WUWT showed up with many others. Now about all that is there are links to social sites.
Correlation and causation insert ugly anti-side. Google found ways to make correlation work for them. The SEO people found ways to make google's use of correlation work for them. Google is still better than AltaVista. The need for revenue $$$$ still exists though.
