Should golf pros have a web site?
Yes, golf professionals should have a web site. At the very least, they should register the domain of their name if possible so that other people will not take it. Then in the future, if one wants to do something with the domain as a web site or use it for email only, one can do so and not have to worry about another person squatting on the domain.
Then the golfer is ready to utilize their domain to show data of themselves to their fans, they can setup their web site to show information accordingly. However, that is only the start. An effective web site is one that is kept up to date on a regular basis. So if a pro golfer does decide to run their own web site they need to realize that it takes some effort to keep things up to date. To help with that, golfers can use data feeds from golf-related web site. For example, GolfInvestors (and other golf-related web sites) can help golfers can utilize data feeds to help keep tournament results, associated news, and sponsorship data up to date on their web site. Then the golfer can focus on writing blog / journal entires to keep their fans coming back to the site.
