It's easy to become a webmaster. But, to become a really good webmaster takes a lot more. And this takes a lot of work and study.
Many years ago, I started yacht racing in Caribbean. I had been sailing since age of 11. I thought that I was an "expert" sailor, but I found that I was really a novice. It's easy to teach someone to sail from point A to point B. BUT, getting from point A to point B in shortest possible time is a whole new story. It took me a full year before I won my first race in a field of 10-12 boats.
Webmastering is very similar. Sure, anyone with more than three brain cells rubbing together can learn HTML, and with all free editors out, it doesn't even take that much effort. (Like learning to sail from one point to another.)
As my own webmaster, being retired, an ex-digital engineer (before psychologist), and computer guru, ex-sales engineer/sales manager, etc. I thought that I had tools to do job.
After having a web site for over a year, I found that I have put thousands of hours of just plain study in to all facets of this fascinating job. Having spent my "retirement" money in sailing around Caribbean for several years, I don't have much money, so had to learn it all on my own. (I don't regret cruising years at all, by way.)
So, what did I learn about webmastering? It's a very complex job, requiring several levels of completely different areas of basic knowledge. I've been studying it intensely for well over a year, and have set up four web sites for different types of sales, (free health advice, a yacht company, a travel company, and a personal site). When starting a web site, what is necessary?
First, webmaster (and you if you have decided to hire one), have to analyse just what you are selling. After that analysis, decide how to present what you are selling, and how to do that on a website. All too many people just jump into a web site using one of fancy editors such as Front Page. Using their "flashy" setups is easy, but is it really way you want to present your message?
How about graphics and salemanship? If your graphics are too big and take too long to load, people will click off before they get to your real message. So, you have to know (or learn) a lot about how to make graphics effective - not just flashy - and how to condense them so that they load as fast as you can get them to. You have to learn a lot more than you wanted to know about graphics, but it's all necessary. If you'd like to see a site (mine) that has minimal graphics for message, loads fast, easy to read, see:
