Honestly, I'm not 100% sure about how the attack vector looks. The fact of the matter is they're basically spamming very specific search queries and not really looking at the results. But most larger search engines store and analyze search queries to for example produce typeahead suggestions or error corrections. You can conceivably poison this data to manipulate how a search engine operates, perhaps directing users to your website or affecting ad auctions. I think the benefit of not directly spamming Google or Bing is that they're harder to identify.
