Yes, making an internet marketing video is a very good idea.
Nobody has mentioned podcasting as a marketing tool - does anybody have any experience of that medium?
Going back to article marketing, I'd like to add that when you write your internet marketing article it's a good idea to do some keyword research and plug some suitable keyword phrases into the title, subtitle and of course the main body of the text.
Don't over-egg the pudding by gratuitous repetition, but you can greatly improve your hit rate by paying attention to how you phrase each sentence and plugging in keyword phrases where they will fit naturally. I usually write the article first and then do my keyword research and modify the article accordingly.
The free keyword search tool at Overture is a bit dated now (last updated January 2007) and doesn't give the complete picture of what keywords people are using to do their searches, but it is great for getting some quick ideas:

If you are just starting out with article marketing, don't always go for the most popular keywords - choose the ones that get between a few hundred and a couple of thousand hits per month. That way your article stands a better chance of getting into the top 10 on the search terms.
