Reference sites and their ad networks

Dictionaries, thesauruses, encyclopedias, translation, calculators and unit converters, statistics and data lookups, legal and medical reference, academic journals and papers, how-to and instructional guides not tied to a single hobby, obituary and public-record search, maps and atlases. The defining trait is that visitors arrive with a specific question and leave once it is answered. Choose education-careers instead when the site teaches a subject through courses, lessons or degree and job guidance. We currently track 691 Reference sites, and this page lists them with the advertising networks each one runs. The most common partner in this category is Ezoic, which appears on 332 of them — a useful signal of who actually buys this kind of inventory, as opposed to who says they do.

Publishers use this page to see which networks accept sites like theirs and at what authority level; buyers use it to size the inventory available in a category before approaching anyone. The table is ordered by authority, so the strongest sites in Reference are at the top.

Reference monetisation — frequently asked

Which ad network is best for a reference site?

By share of sites in this category, Ezoic is the most common partner — it appears on 332 of the 691 Reference sites we track. "Best" depends on your traffic and authority, so compare the tier and median authority on each network's page before applying.

How many networks do reference sites usually run?

Most publishers carry more than one. The "Also uses" column in the table shows the stack on each individual site, which is a more reliable answer for your own situation than an average.

What authority score do these networks require?

The average site in Reference scores 25. Each network page shows its own median, which is the more useful number: it tells you the level of site that network actually accepts, rather than the level it advertises.

Where does this classification come from?

Each site is classified from the text of its own homepage, into one category. A site that spans two categories is filed under the dominant one, so a recipe blog that also reviews cookware appears here rather than in Shopping.
