I stumbled across something by accident that has me perplexed: I was doing research about stock options and ran a Google search for options spread trading bot. The first few pages of SERPs are totally littered with what appear to be cloaked links or re-directs to an options-trading website: IQOption -- which is a spammy-looking options-trading site, which has many online reviews describing them as something of a scam. Tried to link to the search / screenshot, but my account is too new, so I can't...but go ahead and run a Google search for the string above, and you'll see what I mean. There's dozens of URLs seemingly unrelated to anything having to do with options (e.g. dozeo, parablevisions, roman10), which -- if you follow them -- take you to IQOption; and if you check the landing URL for any of them, you'll see the same ?aff=### affiliate code, so this is obviously all the work of a single affiliate. All I want to know is how exactly does this SEO practice work? If you look at cached versions of the pages, it looks like it's just old-school keyword stuffing...buy domain names, stuff with options-related keywords, then re-direct them to your affiliate-link(??) But this seems like exactly the sort of Internet 1.0 technique that I thought Google long-ago snuffed out. And this is painfully transparent. And I've been seeing this happening across several of my google searches, in several different industries. So what's going on here? I'm just surprised that it's even working so well, given how crude it appears to be.
