In my opinion, music is a no- no, even if it is a catchy tune. I find myself leaving a website almost immediately if there is music playing. I find it most distracting.
I like pasture pictures the most. Fancy calves in fancy dress make me wonder what they are hiding, however, I use show pictures if the animal(s) have placed well or won. I carry a digital camera in every vehicle and take literally hundreds of pictures when I check cows. You will be surprised how many times you will see an animal standing perfectly and you can oftentimes get a good picture without trying. The picture of Major Leroy, under my name at the side was taken out my truck window as I drove up to him. I got lucky as I snapped a few pictures before I got out of the truck as I thought he might move. It was early in the morning, and I snapped several pictures in 15 minutes that we will be using on our website, and in advertising and sales in the coming months.
Video clips are a nice touch, but I would agree that you may lose some interested people simply because the website will take so long to download. It may be a suggestion to use good pictures on the website, and mention that video is available. When someone contacts you to ask for the video, you know you have definite interest, and you can follow up following them seeing the video.
Our website has probably been the greatest promotional tool we have ever used. Within a week of getting our internet up and running, I had a commercail man email me about bulls. I ran out to the bull pen and snapped some pictures and emailed him back with the info. Sold two bulls that night to a guy I had never met and who had never seen the bulls. We have sold numerous embryos to 5 countries, from our website, and have never spoke with the buyers. Last week I sold $6000 of embryos to Scotland to a person I have never heard of and never spoke too. His certified cheque arrived and the embryos are on their way to Britain and should be there tomorrow. Your website literally allows you to market to the world without ever leaving home, and for very little costs. Quite frankly, I could have never dreamt that a website would generate as much interest and business.
It is very important to update your website on a very regular basis. We did this fro the first couple years, on a monthly basis, but are very guilty of not doing it for a few months now. Actually, I just finished writing out the changes and picked out some new pictures tonight, and hopefully, my wife can get these changes completed in the next few days. I am lucky in that my wife has some computer talents and does our websites along with a few others. We have been renovating our house and that has seemed to take more time than we planned.... but it certainly is not a good enough excuse.
If people like what they see on your website, they will stop back at it regularly to see if you have added some info. I get frustrated with some pretty big breeders who have not changed their websites for many months... some for years. Your website can act as a very good communication tool to an interested audience.
Use the best pictures you can get. If you aren't happy with a picture keep trying until you get a better one. Good pics will make you more money than anything else you can do.
