I have a collection of websites that I do not control in terms of content or page creation/editing. As a result, I have no way to add links to outside sites on any existing or new pages. Given this, how can I go about finding and requesting other sites link back to our sites/pages if I cannot offer them a link to their site in return? I know that content is a link driver, but I do not control the content, so I cannot develop new content to help drive links.
I appreciate any help/advice any experts can provide.
