Guides — category index

Buyer guides answer one buying question each, such as where to buy backlinks, with a short ordered pick drawn from one ranking. Each guide names its first pick in the opening paragraph and links every provider's own website, its article and its rankings.

The table at the top of each guide renders from the current round's results, so it changes when the ranking it draws on is rescored. Prices and terms in a guide are dated on the day they were read from the providers' own pages.
