Without the ad-tech bloat.

For the life of jsschools.com. If we shut the site down, we refund the unused portion. We have no plans to shut it down — we've been building for 5+ years.

For Lesson Banner, the side banner on every lesson rotates randomly every second among all Lesson Banner partners — equal fair-share, no auction, no bidding. For Hero Sponsor, the home-page hero title is randomly picked from the Hero Sponsor pool on every page visit. Single Page ads don't rotate — you own that page outright.

Your share dilutes proportionally — that's the trade for a permanent rotation slot at a flat fee. We publish the current partner count on this page so you always know what you're getting. Realistically we cap the pool well below "too thin to notice".

Two reasons. First, they slow pages down with megabytes of tracking JS. Second, the content next to a Google Ad is, statistically, whatever pays the most — usually irrelevant to our readers and often actively user-hostile. We'd rather curate.

A short tagline (≤ 50 chars), a target URL, and a logo. For Hero Sponsor, we also ask for a 50-word write-up. We'll handle the styling so your ad fits the page. No animation, no auto-play, no popups, ever.

Yes — one update per year is included. Want to swap copy or change the link? Email us; we'll deploy the change within 48 hours.

No. We don't run any ad-tracking infrastructure — that's the whole point of buying a placement here instead of on an ad network. Performance measurement is the advertiser's responsibility: add UTM parameters to your URL and read the traffic in your own analytics.
