Sitewide sponsor slot

Reach designers while they choose what to buy

Your product sits in the sponsor rail on every page of the site — the directory, every tool page, the free tools and the blog. Not a banner in one corner of one page.

How it works: Logo, name and one line, in a fixed card outside the content. There are only 6 slots, so your card is on screen the whole time, not one of dozens taking turns.
What it never does: It never changes a ranking, softens a drawback, buys a listing or removes a competitor. Every card is labelled Sponsored. That rule is why the recommendations are worth sponsoring.
Availability: 6 slots open right now.
