What does a search arbitrage page look like?
Most look like a short article with a box of suggested searches in or under the text, such as "Best SUV lease deals" or "Dental implant costs near you". Tapping a suggestion opens a results page on the same site, with a few sponsored listings labelled as ads. Older versions were a bare list of keywords with no article at all.
The article version is a content page carrying a Related Search on Content unit. The suggestions are related search terms, some chosen by Google and some proposed by the publisher through the terms parameter. The results page behind them is powered by AdSense for Search.
The bare version is a keyword lander, common on parked domains and on Bing or Yahoo feeds. Either way, the tell-tale signs are a domain you have never heard of, an advert that brought you there, and a page whose main job is to offer you another click. That alone does not make it dishonest. It becomes a problem when the advert promised something the page does not deliver.
