Recently I gave a copyright release to a European professor who has a Phd level book coming out in a few months allowing him to cite and quote one of the articles I wrote and published on my site. The citation refers back to the url of the original article and mentions my name and the site name. From what I understand, my article is being quoted verbatim in its entirety. The topic of the book is highly relevant to my website. This is a professional/academic book and there is very little chance of it being published in an electronic machine readable format. It is also likely to be read in a very small niche circle. The publisher is John Wiley.
I have an informational/paid membership site based in US with global clientele.
I consider this a very authoritative citation and I am wondering if this is something that Google might consider as a quality signal. Or do they even have the ability to recognize the citation in print.
While the algo can't read books per se, the effect of this is likely to be that readers will type your URL into their Google search bar. Google seems to recognize "type ins" as an indicator that your site's being talked about offline, and they seem to reward it.
