A really cool thing about this domain is the quality of backlinks. There was nothing spammy about it ever, and the original owner seems to have put a lot of thought and effort into link building as the links feature a highly diverse array of anchor texts a lot of which refer to particular titles of Spanish literature.
When I bought this domain (September 2015) I was looking for a head start in the niche of Spanish literature, and the overall weight of the domain's backlink portfolio appeared to be in the $2.5-3.5K range as approximated by the amount of money needed to achieve similar qualty and Moz metrics by hiring a SEO agency. Mid 20-s for both DA and PA is quite strong for the Spanish-speaking Internet (equivalent to perhaps mid 30-s in the English-speaking Internet), but unfortunately, my project came to a screeching halt (I understand Spanish but I am not fluent enough to develop the domain on my own).
The best I could do was to use it for some English marketing, but, as expected, the results were insufficient. I hate to see the domain not working for the right cause, so I am looking for a buyer who can do it justice. There is still a lot of value in the backlinks, but I set the reserve price at a lower level, so the buyer could get value for his or her money.
To simplify things for you, I attached an Excel export of the backlinks as found by Ahrefs on 4/9/2017. Also, feel free to ask for view-only access to Google Webmaster tools. Like I said, I speak Spanish a little, so you can write to me in that language if that is easier for you. Don't expect me to write back with perfect grammar, though :-).
All in all, if you are looking for a seasoned domain with quality backlinks to attract Spanish-speaking audience interested in books, literature and publishing look no further. Thank you for your interest, and good luck!
