I have a site where each page has approx. 500 words of unique content and 500 words of advertising content made with 5 affiliate links. The advertising content is the same on each page.
Is there a way to write that advertising content in such a way that it is ignored by search engines? Javascript text?
This isn't secret text, or keyword-stuffed text. Nothing bad will happen if search engines read it... except that it dissolves the page-specific content.
