Every agency in the directory is scored against Avenue Z on the sectors both work in, the services both name, whether they sell to the same kind of buyer and whether they are in the same country. Sectors count for more than services, because two agencies serving the same industry are closer substitutes than two that both list technical SEO, which nearly every agency does.
Nothing here is paid for. Where a Featured agency appears it is labelled, and it earns its place on the same match as everything else. Details come from each agency’s own website, checked before the listing went live, and claimed listings add pricing, team size and the engines covered.
