competitive key term in the financial sector, ranking top 3, unrelated to the topic, ranks only because it links to a relevant site using invisible links in the footer.
I see a similar example in the automotive niche. A completely unrelated charity site ranks for an automotive money-keyword just because of an anchor text in the hidden link to an automotive store. Looks like a hacked site.
What's even more funny, that the site it is linking to, the one that has many more hidden links like that (on other, probably hacked, sites) is ranking even higher!
