In searching for copied content, I was really surprised to find that a well-respected online retailer in my niche had stolen a paragraph or two about a brand of widgets. It's something I wrote a few years ago, but I would have thought they would be above such things, particularly since they already rank extremely well.
I'm finding portions of my content scraped as well as the better part of whole pages. I don't see filing complaints as a solution, as it's very time-consuming. The material copied is years, months or even weeks old. It would seem that the only solution would be to constantly re-write pages.
How would Google rank sites where the text changes every few weeks?
