I'm marketing an ebook. My main pages are an article on a good article site and my main blog post page (on my domain name). When I search for the ebook title in all of the main search engines and use quotation marks, both of my main sites are on the front page, but when I don't use quotation marks, both pages fall to the third or so page. I'm using link wheels to build backlinks. Is there any reason this is happening and is there something I can do to better my results without quotations? Thanks for any suggestions.
