"Is this illegal?" IANAL, but in certain jurisdictions, most certainly yes. Many countries have copyright laws that protect compilations of things that are individually not worthy of copyright, for example telephone books. Copying down an individual telephone book entry is of course not a copyright violation, but copying the whole listing in a systematic fashion is. I'd guess that this law applies to search engine rankings as well - rankings/listings of individual items that are not protected by copyright, but where a lot of effort goes into producing the listing itself.
