I'm working on a series of guest posts to help promote a site. These are competitive, high quality posts from a well-respected resource in the industry. I placed the author introduction at the front of the posts, with anchor text for the keywords we are targetting (e.g., "This is a guest post by John Doe, a [keyword] who ... and writes about [keyword].").
I understand that having the anchor text in a prominent location - such as near the front of the post - will probably be more authoritative than a sentence at the very end. My question: how significant is this difference?
The blog that I am posting on wants to include author information at the end only and only have one link using the site name (which doesn't contain keywords). The post I sent had two deep links using keyword-rich anchor text, placed at the beginning. I am trying to decide whether to walk away and keep shopping the material around.
