A popunder that actually opens behind the page
The swap technique, plus the one line that stops the visitor's own click from cancelling it — the reason most popunder code silently loses the traffic it was supposed to send.
Ads, Traffic and Offerwalls
Banner serving, popunders, shortlink APIs, PTC runners and postback handling.

A banner embed that does not get cut off on a phone
A 728x90 in a 360px column overflows or gets clipped. Two CSS properties on the iframe and one change in the renderer fix it for every publisher at once.
Serve a banner with a rotation and a house fallback
Pick a creative that matches the slot size, prefer one the visitor has not already been paid for today, and never leave the slot empty.
Verify that someone owns the site they registered
Fetch the page, look for your token in a meta tag, and only let verified sites earn. The empty-needle bug in this check is worth knowing about before it bites you.
A shortlink API compatible with what faucet scripts expect
Faucet software already knows how to talk to shortlink providers. Match the contract they expect and operators can point their existing config at you without writing anything.
Handle an offerwall postback without paying twice
Signature check, unique constraint, credit inside a transaction. Networks retry postbacks, so the same completion will arrive more than once.
A PTC offer runner that pays only on a real view
Open the target, run the timer, verify server-side, credit once. The four steps and the checks that belong to each.
A surf engine that cycles a visitor through sites
Server-held session state, one destination at a time, dwell enforced on the server. The core of a traffic exchange in one table and two functions.
Credit maths for a traffic exchange
Send N, receive M, and keep the difference as the house margin. The one transaction that moves credits between two members without leaking any.
Gate earning by referer without blocking the page
Check that the request came from the site the slot belongs to. Refuse the credit, never the content — the same rule that keeps you out of trouble everywhere else.
An ad slot manager with a fallback chain
Sponsor, then network, then house, then nothing. One function that means an unsold slot never leaves a hole in the page.
