The subject of this post is something that little people consider, when they buy a data base, is probable that has been sold them, also has been sold them to other people, having this a simple end, contained duplicate, yes! , my better friend. The recommendation for those who buy data bases is to take the work to modify the content, the first lines at least, I do not talk about to erase everything and to rewrite it, but to change words to him, in case of being possible to change the position of the paragraphs. The important thing to change the first lines is that generally they are those that use the systems of handling of content by defect to create the descriptions of the pages. Other things to consider are the spelling, the writing, and the origin. The spelling perhaps not but the important thing, but a bad writing can at least be a delicate subject but, because the automatic text correctors do not know to write up, not so far.
Origin is key, because there is some alive that simply copies of different sites information they are and it keeping and they load later it in a data base they sell and it, this can cause problems to us with those who have been the original owners of the content.
