Great experiment. I really enjoyed reading about it.

Two observations. One is that the swimwatch pic is NAMED ‘tom critchlow’ and linked to with ‘tom critchlow image’ anchor text. I think the word IMAGE is more important because since ur using the ‘image search’ in google.

My second observation is that the post titled ’seo experiment’ has a lot of surround text with ‘tom critchlow’ but the image itself is NOT named ‘tom critchlow’ it’s named ‘att00068_resize.jpg’.

My third observation is that Yahoo Search Explorer says ‘att00068_resize.jpg’ does NOT have any links pointing to it.

In conclusion, maybe a follow-up experiment could be ‘what approx. weight does google and others give to having the picture named after the keyword’.

Although, I think we both know naming the image after a keyword IS a factor, but the question is ‘how much of a factor….’

Great stuff man. Your great on WBF.
