I am hoping someone can help me regarding anchor text. Of course, I reaiize the importance of the "anchor text" after a link and before the </a> but my question is about "not" using any anchor text.
For example, in my blog and websites there are often images which are clickable and go to a linked site since they are preceeded by <a href=. However, the image is there mostly for its graphical impact and also acts as a link when clicked.
My question is does the fact there may be NO anchor text detract from the links value as far as the search engines are concerned and if the answer is yes, to what degree and is there an alternative?
