We've been having serious conversion issues as of late. Our advertising spend has been very high but our ROI has been dead. Doing digging and it was suggested to see what happens when we load our site in a browser that has a third party tool bar installed (pay per view tool bar I was told it is called). What we discovered is on our page load, a different site from the same vertical loads over our site. In addition, our site is framed in banners and copy within our site has added links to exterior offers that are not ours. Is there anything we can do about this?
