A very helpful article. Effective keywording is a skill and takes some effort, but I think it is critical for success in micro stock. I am wondering, does the number of keywords used for an image have any effect on what page of search results the image is shown on?
Art always affirms that too much keywords affects placement in the search results negatively.
However, recently, I read a comment from some admin who told that number does not matter, there should be as many KW as image needs (unfortunately, I do not remember the thread).
I think that number of words itself has no effect as soon as all they are RELEVANT ones. But if one increses the number of KW ONLY TO KEEP it large one unavoidable has to use NON-RELEVANT ones. In this case placement in the search results becomes worse. 'Relevancy requirement' leads to 15-20 keywords in most of practical cases, on my experience.
