If you're going to use images on your site, make sure you use an Alt Image Tag. You'll need one for each image, and each tag will need to include a couple of your target keywords. Without the tags, the spiders won't pick up on your pictures.
As for the rest of the content, you may want to consider starting a blog. That would be the best way to sum up important points or give out tips in a way that's informative and friendly (after all, it is a hobby site, which gives you leeway to make it a little more relaxed)
If you're not a golf pro yourself, you're going to have to research, research, research. And don't put any videos on your site unless you know you have permission to do so.
Thanks for replies, Yeah youtube has some cool vids, but i dont know how i stand with permissions/copyright issues. I am not a golf pro but i do have quite a bit if knowledge of the game, so could come up with some content. The site will be aimed at a County wide society of golfers with a forum attached to arrange games and stuff.
