There are 3 different names for this type of strategy:
Bum Marketing
Piggybacking
Parasite Hosting
They all mean the same thing. Create a well optimized article and put it on an authority website. Putting in on your own website won’t get you high rankings because its damn near impossible to outrank some of these high budget and very old, authority websites. This strategy works very well and I use it all the time. Your articles wont maintain their high SERP’s though for more than a few days to a week unless you have a solid link building campaign going to that article on the authority site. Or you can choose some less competitive search terms and they might stay there longer. Depends on the niche and doing the proper research.
